    Validation of the burn intervention score in a National Burn Centre2018In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, no 5, p. 1159-1166Article in journal (Refereed)
    Abstract [en]

    The Linköping burn score has been used for two decades to calculate the cost to the hospital of each burned patient. Our aim was to validate the Burn Score in a dedicated Burn Centre by analysing the associations with burn-specific factors: percentage of total body surface area burned (TBSA%), cause of injury, patients referred from other (non-specialist) centres, and survival, to find out which of these factors resulted in higher scores. Our second aim was to analyse the variation in scores of each category of care (surveillance, respiration, circulation, wound care, mobilisation, laboratory tests, infusions, and operation).

    We made a retrospective analysis of all burned patients admitted during the period 2000–15. Multivariable regression models were used to analyse predictive factors for an increased daily burn score, the cumulative burn score (the sum of the daily burn scores for each patient) and the total burn score (total sum of burn scores for the whole group throughout the study period) in addition to sub-analysis of the different categories of care that make up the burn score.

    We retrieved 22 301 daily recordings for inpatients. Mobilisation and care of the wound accounted for more than half of the total burn score during the study. Increased TBSA% and age over 45 years were associated with increased cumulative (model R2 0.43, p < 0.001) and daily (model R2 0.61, p < 0.001) burn scores. Patients who died had higher daily burn scores, while the cumulative burn score decreased with shorter duration of hospital stay (p < 0.001).

    To our knowledge this is the first long term analysis and validation of a system for scoring burn interventions in patients with burns that explores its association with the factors important for outcome. Calculations of costs are based on the score, and it provides an indicator of the nurses’ workload. It also gives important information about the different dimensions of the care provided from thorough investigation of the scores for each category.

    Division of overall duration of stay into operative stay and postoperative stay improves the overall estimate as a measure of quality of outcome in burn care.2017In: PLOS ONE, E-ISSN 1932-6203, Vol. 12, no 3, article id e0174579Article in journal (Refereed)
    Abstract [en]

    Patients and Methods: Surgically managed burn patients admitted between 2010-14 were included. Operative stay was defined as the time from admission until the last operation, postoperative stay as the time from the last operation until discharge. The difference in variation was analysed with F-test. A retrospective review of medical records was done to explore reasons for extended postoperative stay. Multivariable regression was used to assess factors associated with operative stay and postoperative stay.less thanbr /greater thanResults: Operative stay/TBSA% showed less variation than total duration/TBSA% (F test = 2.38, pless than0.01). The size of the burn, and the number of operations, were the independent factors that influenced operative stay (R2 0.65). Except for the size of the burn other factors were associated with duration of postoperative stay: wound related, psychological and other medical causes, advanced medical support, and accommodation arrangements before discharge, of which the two last were the most important with an increase of (mean) 12 and 17 days (pless than0.001, R2 0.51).less thanbr /greater thanConclusion: Adjusted operative stay showed less variation than total hospital stay and thus can be considered a more accurate outcome measure for surgically managed burns. The size of burn and number of operations are the factors affecting this outcome measure.

    Improvement in mortality at a National Burn Centre since 2000: Was it the result of increased resources?2017In: Medicine, ISSN 0025-7974, E-ISSN 1536-5964, Vol. 96, no 25, article id e6727Article in journal (Refereed)
    Abstract [en]

    Abstract The aim of this study was to find out whether the charging costs (calculated using interventional burn score) increased as mortality decreased. During the last 2 decades, mortality has declined significantly in the Linköping Burn Centre. The burn score that we use has been validated as a measure of workload and is used to calculate the charging costs of each burned patient. We compared the charging costs and mortality in 2 time periods (2000–2007 and 2008–2015). A total of 1363 admissions were included. We investigated the change in the burn score, as a surrogate for total costs per patient. Multivariable regression was used to analyze risk-adjusted mortality and burn score. The median total body surface area % (TBSA%) was 6.5% (10–90 centile 1.0–31.0), age 33 years (1.3–72.2), duration of stay/ TBSA% was 1.4 days (0.3–5.3), and 960 (70%) were males. Crude mortality declined from 7.5% in 2000–2007 to 3.4% in 2008–2015, whereas the cumulative burn score was not increased (P=.08). Regression analysis showed that risk-adjusted mortality decreased (odds ratio 0.42, P=.02), whereas the adjusted burn score did not change (P=.14, model R2 0.86). Mortality decreased but there was no increase in the daily use of resources as measured by the interventional burn score. The data suggest that the improvements in quality obtained have been achieved within present routines for care of patients (multidisciplinary/ orientated to patients’ safety).

    Abbreviation: TBSA% = total body surface area %.

    Versatility of the Extensor Digitorum Brevis Muscle Flap in Lower Limb Reconstruction2018In: Plastic and Reconstructive Surgery - Global Open, E-ISSN 2169-7574, Vol. 6, no 12, article id e2071Article in journal (Refereed)
    Abstract [en]

    Background: Reconstruction of complex defects in the lower leg is a challenge. Although microvascular free tissue transfer is a popular technique, experience and available resources limit its use. Furthermore, free tissue transfer is not always required in the reconstruction of small lower leg defects, as many of them can be reconstructed with local alternatives such as an extensor digitorum brevis flap (EDB). Our aim was to describe our experience of the last 20 years with the EDB as a local muscle flap to cover small complex lower leg defects to establish its clinical feasibility and to document its associated complications. Methods: All adult patients who were operated with EDB flap reconstruction of the lower limb during 1997–2017 at the Department of Hand and Plastic Surgery, Linköping University Hospital, were included in this retrospective study. Results: Of 64 patients operated, only 7 had total flap failure, and the rate of complete success was 73% (47/64). Most of the skin defects were associated with fractures or complications thereof and were located in the ankle region, the dorsum of the foot, and the distal third of tibia or even the proximal tibia. Defects in the malleolar region and coexisting cardiovascular condition were factors associated with flap loss (either partial or total). Conclusion: The pedicled EDB-flap has, in our hands, proved to be a versatile and safe reconstructive option in the reconstruction of small defects in the lower leg and foot. Long-time follow-up is, however, recommended.

    Needle Fasciotomy or Collagenase Injection in the Treatment of Dupuytren’s Contracture: A Retrospective Study2020In: Plastic and Reconstructive Surgery - Global Open, E-ISSN 2169-7574, Vol. 8, no 1Article, review/survey (Refereed)
    Abstract [en]

    Background: Dupuytren’s contracture is common among older people in Sweden. Previous studies comparing the treatment with an injection of collagenase with percutaneous needle fasciotomy found no differences. Methods: We retrospectively compared the degree of improvement in the deficit in extension of the joints in 2 groups of patients who had been treated with collagenase (71 fingers) or needle fasciotomy (109 fingers) before and 1 year after treatment. We compared the improvement of the extension deficit among the metacarpophalangeal (MCP) and proximal interphalangeal joints before and after the intervention; additionally, the level of improvement was classified into 3 levels (mild = 0° to 29°; moderate = 30° to 60°; considerable = 61° and more). Results: The degree of improvement of extension in the MCP joints was 11° greater in the collagenase group (P = 0.001). The number of patients who had an improvement of >60° (considerable) in extension was greater in the collagenase group (P = 0.02). Conclusion: Collagenase was more effective than needle fasciotomy in treating extension deficits of the MCP joints in Dupuytren’s contracture in this retrospective analysis. Further prospective studies are required to confirm the finding.

    Lidocaine infusion has a 25% opioid-sparing effect on background pain after burns: A prospective, randomised, double-blind, controlled trial2020In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 46, no 2, p. 465-471Article in journal (Refereed)
    Abstract [en]

    Background

    The pain of a burn mainly results from the inflammatory cascade that is induced by the injured tissue, and is classified as background, breakthrough, procedural and postoperative pain. High doses of opioids are usually needed to treat background pain, so its management includes a combination of types of analgesia to reduce the side effects. Lidocaine given intravenously has been shown in two small, uncontrolled studies to have an appreciable effect on pain after burns.

    Objectives

    In this prospective double-blind controlled trial we aimed to examine and quantify the opioid-sparing effect of a continuous infusion of lidocaine for the treatment of background pain during the early period after a burn.

    Methods

    Adult patients injured with burns of >10 total body surface area burned (TBSA%) and treated with a morphine based patient-controlled analgesia device (PCA) were randomised to have either lidocaine infusion starting with a bolus dose (1 mg lidocaine/kg) followed by continuous infusion (180 mg lidocaine/hour) or a placebo infusion, for seven consecutive days. Total daily consumption of opioids (mg) and amount of pain (visual analogue score, VAS) were recorded.

    Results

    We included 19 patients, 10 of whom were given a lidocaine infusion. There were no differences between groups in VAS, TBSA%, time of enrolment to the study since the initial burn, or duration of hospital stay. The opioid consumption in the lidocaine group declined by roughly 25% during the period of the study.

    Conclusion

    An intravenous infusion of lidocaine was safe and had an opioid-sparing effect when treating background pain in burns.

    Use of the burn intervention score to calculate the charges of the care of burns2019In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 45, no 2, p. 303-309Article in journal (Refereed)
    Abstract [en]

    Background To our knowledge this is the first published estimate of the charges of the care of burns in Sweden. The Linköping Burn Interventional Score has been used to calculate the charges for each burned patient since 1993. The treatment of burns is versatile, and depends on the depth and extension of the burn. This requires a flexible system to detect the actual differences in the care provided. We aimed to describe the model of burn care that we used to calculate the charges incurred during the acute phase until discharge, so it could be reproduced and applied in other burn centres, which would facilitate a future objective comparison of the expenses in burn care. Methods All patients admitted with burns during the period 2010–15 were included. We analysed clinical and economic data from the daily burn scores during the acute phase of the burn until discharge from the burn centre. Results Total median charge/patient was US$ 28 199 (10th–90th centiles 4668-197 781) for 696 patients admitted. Burns caused by hot objects and electricity resulted in the highest charges/TBSA%, while charges/day were similar for the different causes of injury. Flame burns resulted in the highest mean charges/admission, probably because they had the longest duration of stay. Mean charges/patient increased in a linear fashion among the different age groups. Conclusion Our intervention-based estimate of charges has proved to be a valid tool that is sensitive to the procedures that drive the costs of the care of burns such as large TBSA%, intensive care, and operations. The burn score system could be reproduced easily in other burn centres worldwide and facilitate the comparison regardless of the differences in the currency and the economic circumstances.

    Evaluation of Glandular Liposculpture as a Single Treatment for Grades I and II Gynaecomastia2018In: Aesthetic Plastic Surgery, ISSN 0364-216X, E-ISSN 1432-5241, Vol. 42, no 2, p. 1222-1230Article in journal (Refereed)
    Abstract [en]

    Background

    Gynaecomastia is a benign enlargement of the male breast, of which the psychological burden on the patient can be considerable, with the increased risk of disorders such as depression, anxiety, and social phobia. Minimal scarring can be achieved by liposuction alone, though it is known to have a limited effect on the dense glandular and fibroconnective tissues. We know of few studies published on “liposuction alone”, so we designed this study to evaluate the outcome of combining liposuction with glandular liposculpturing through two axillary incisions as a single treatment for the management of grades I and II gynaecomastia.

    Methods

    We made a retrospective analysis of 18 patients with grade I or II gynaecomastia who were operated on by combined liposuction and glandular liposculpturing using a fat disruptor cannula, without glandular excision, during the period 2014–2016. Patient satisfaction was assessed using the Breast Evaluation Questionnaire (BEQ), which is a 5-point Likert scale (1 = very dissatisfied; 2 = dissatisfied; 3 = neither; 4 = satisfied; 5 = very satisfied). The post-operative aesthetic appearance of the chest was evaluated by five independent observers on a scale from 1 to 5 (5 = considerable improvement).

    Results

    The patient mean (SD) overall satisfaction score was 4.7 (0.7), in which 92% of the responders were “satisfied” to “very satisfied”. The mean (SD) BEQ for all questions answered increased from 2.1 (0.2) “dissatisfied” preoperatively to 4.1 (0.2) “satisfied” post-operatively. The observers’ mean (SD) rate for the improvement in the shape of the front chest wall was 4.1 (0.7). No haematomas were recorded, one patient developed a wound infection, and two patients complained of remnants of tissue. The median (IQR) body mass index was 27.4 (26.7–29.4), 11 patients had gynaecomastia grade I, and 7 patients grade II. The median (IQR) volume of aspirated fat was 700 ml (650–800), operating time was 67 (65–75) minutes, 14 patients had general anaesthesia, and hospital charges were US$ 538 (481–594).

    Conclusions

    Combined liposuction and liposculpturing using the fat disruptor cannula resulted in satisfied patients and acceptable outcomes according to the observers’ ratings. It could be a useful alternative with an outcome that corresponds to that of more expensive methods.

    Pros and Cons of Early and Late Skin Grafting in Children with Burns—Evaluation of Common Concepts2022In: European Burn Journal, E-ISSN 2673-1991, Vol. 3, no 1, p. 180-187Article in journal (Refereed)
    Abstract [en]

    Background: There is no consensus regarding the timing of surgery in children with smallerburn size, specifically in deep dermal burns. Delayed surgery has risks in terms of infection anddelayed wound healing. Early surgery also risks the removal of potentially viable tissue. Our aim wasto investigate the effect of the timing of surgical intervention on the size of the area operated on andthe time to wound healing. Methods: A retrospective analysis for all children (<18 years) with burnsize <20% body surface area (BSA%) during 2009–2020 who were operated on with a split-thicknessskin graft. The patients were grouped by the timing of the first skin graft operation: early = operatedon within 14 days of injury; delayed = operated on more than two weeks after injury. Results: A totalof 84 patients were included in the study, 43 who had an early operation and 41 who had a delayedoperation. There were no differences between the groups regarding burn size, or whether the burnswere superficial or deep. The mean duration of healing time was seven days longer in the group withdelayed operation (p = 0.001). The area operated on was somewhat larger (not significantly so) in thegroup who had early operation. Nine children had two skin graft operations, eight in the early groupand one in the delayed group (p = 0.03). Conclusion: The patients who were operated on early hadthe advantage of a shorter healing time, but there was a higher rate of complementary operationsand a tendency towards a larger burn excision.

    Development of delirium: Association with old age, severe burns, and intensive care2020In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 46, no 4, p. 797-803Article in journal (Refereed)
    Abstract [en]

    Background Delirium is defined as a disturbance of attention and awareness that develops over a short period of time, is a change from the baseline, and typically fluctuates over time. Burn care involves a high prevalence of known risk factors for delirium such as sedation, inflammation, and prolonged stay in hospital. Our aim was to explore the extent of delirium and the impact of factors associated with it for adult patients who have been admitted to hospital with burns. Methods In this retrospective study, all adult patients who had been admitted with burns during a four-year period were studied, including both those who were treated with intensive care and intermediate care only (no intensive care). Daily records of the assessment of delirium using the Nursing Delirium Screening Scale (Nu-DESC) were analysed together with age, sex, the percentage of total body surface area burned, operations, and numbers of wound care procedures under anaesthesia, concentrations of plasma C-reactive protein, and other clinical variables. Logistic regression was used to analyse factors that were associated with delirium and its effect on mortality, and linear regression was used to analyse its effect on the duration of hospital stay. Results Fifty-one patients (19%) of the total 262 showed signs of delirium (Nu-DESC score of 2 or more) at least once during their stay in hospital. Signs of delirium were recorded in 42/89 patients (47%) who received intensive care, and in 9/173 (5%) who had intermediate care. Independent factors for delirium in the multivariable regression were: age over 74 years; number of operations and wound care procedures under anaesthesia; and the provision of intensive care (area under the curve 0.940, 95% CI 0.899–0.981). Duration of hospital stay, adjusted for age and burn size, was 13.2 (95% CI 7.4–18.9, p < 0.001) days longer in the group who had delirium. We found no independent effects of delirium on mortality. Conclusion We found a strong association between delirium and older age, provision ofr intensive care, and number of interventions under anaesthesia. A further 5% of patients who did not receive intensive care also showed signs of delirium, which is a finding that deserves to be thoroughly investigated in the future.

    Microbial cellulose dressing compared with silver sulphadiazine for the treatment of partial thickness burns: A prospective, randomised, clinical trial2018In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 44, no 8, p. 1982-1988Article in journal (Refereed)
    Abstract [en]

    Background

    The current treatment for partial thickness burns at the trial site is silver sulphadiazine, as it minimises bacterial colonisation of wounds. Its deleterious effect on wound healing, together with the need for repeated, often painful, procedures, has brought about the search for a better treatment. Microbial cellulose has shown promising results that avoid these disadvantages. The aim of this study was therefore to compare microbial cellulose with silver sulphadiazine as a dressing for partial thickness burns.

    Method

    All patients who presented with partial thickness (superficial and deep dermal) burns from October 2014 to October 2016 were screened for this randomised clinical trial. Twenty patients were included in each group: the cellulose group was treated with microbial cellulose sheets and the control group with silver sulphadiazine cream 10 mg/g. The wound was evaluated every third day. Pain was assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) scale during and after each procedure. Other variables recorded were age, sex, percentage total body surface area burned (TBSA%), clinical signs of infection, time for epithelialisation and hospital stay. Linear multivariable regression was used to analyse the significance of differences between the treatment groups by adjusting for the size and depth of the burn, and the patient’s age.

    Results

    Median TBSA% was 9% (IQR 5.5–12.5). The median number of dressing changes was 1 (IQR 1–2) in the cellulose group, which was lower than that in the control group (median 9.5, IQR 6–16) (p < 0.001). Multivariable regression analysis showed that the group treated with microbial cellulose spent 6.3 (95% CI 0.2–12.5) fewer days in hospital (p = 0.04), had a mean score that was 3.4 (95% CI 2.5–4.3) points lower during wound care (p < 0.001), and 2.2 (95% CI 1.6–2.7) afterwards (p < 0.001). Epithelialisation was quicker, but not significantly so.

    Conclusion

    These results suggest that the microbial cellulose dressing is a better first choice for treatment of partial thickness burns than silver sulphadiazine cream. Fewer dressings of the wound were done and, combined with the low pain scores, this is good for both the patients and the health care system. The differences in randomisation of the area of burns is, however, a concern that needs to be included in the interpretation of the results.

    Cardiac dysfunction after burns2008In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 34, no 5, p. 603-609Article in journal (Refereed)
    Abstract [en]

    Objectives

    Using transoesophageal echocardiography (TEE) we investigated the occurrence, and the association of possible abnormalities of motion of the regional wall of the heart (WMA) or diastolic dysfunction with raised troponin concentrations, or both during fluid resuscitation in patients with severe burns.

    Patients and methods

    Ten consecutive adults (aged 36–89 years, two women) with burns exceeding 20% total burned body surface area who needed mechanical ventilation were studied. Their mean Baux index was 92.7, and they were resuscitated according to the Parkland formula. Thirty series of TEE examinations and simultaneous laboratory tests for myocyte damage were done 12, 24, and 36 h after the burn.

    Results

    Half (n = 5) the patients had varying grades of leakage of the marker that correlated with changeable WMA at 12, 24 and 36 h after the burn (p ≤ 0.001, 0.044 and 0.02, respectively). No patient had WMA and normal concentrations of biomarkers or vice versa. The mitral deceleration time was short, but left ventricular filling velocity increased together with stroke volume.

    Conclusion

    Acute myocardial damage recorded by both echocardiography and leakage of troponin was common, and there was a close correlation between them. This is true also when global systolic function is not deteriorated. The mitral flow Doppler pattern suggested restrictive left ventricular diastolic function.

    Hemodynamic Changes During Resuscitation After Burns Using the Parkland Formula2009In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 66, no 2, p. 329-336Article in journal (Refereed)
    Abstract [en]

    Background: The Parkland formula (2-4 mL/kg/burned area of total body surface area %) with urine output and mean arterial pressure (MAP) as endpoints; for the fluid resuscitation in burns is recommended all over the world. There has recently been a discussion on whether central circulatory endpoints should be used instead, and also whether volumes of fluid should be larger. Despite this, there are few central hemodynamic data available in the literature about the results when the formula is used correctly.

    Methods: Ten burned patients, admitted to our unit early, and with a burned area of >20% of total body sur-face area were investigated at 12, 24, and 36 hours after injury. Using transesophageal echocardiography, pulmonary artery catheterization, and transpulmonary thermodilution to monitor them, we evaluated the cardiovascular coupling when urinary output and MAP were used as endpoints.

    Results: Oxygen transport variables, heart rate, MAP, and left ventricular fractional area, did not change significantly during fluid resuscitation. Left ventricular end-systolic and end-diastolic area and global end-diastolic volume index increased from subnormal values at 12 hours to normal ranges at 24 hours after the burn. Extravascular lung intrathoracal blood volume ratio was increased 12 hours after the burn.

    Conclusions: Preload variables, global systolic function, and oxygen transport recorded simultaneously by three separate methods showed no need to increase the total fluid volume within 36 hours of a major burn. Early (12 hours) signs of central circulatory hypovolemia, however, support more rapid infusion of fluid at the beginning of treatment.

    Human cardiovascular dose-response to supplemental oxygen2007In: Acta Physiologica, ISSN 1748-1708, E-ISSN 1748-1716, Vol. 191, no 1, p. 15-24Article in journal (Refereed)
    Abstract [en]

    Aim: The aim of the study was to examine the central and peripheral cardiovascular adaptation and its coupling during increasing levels of hyperoxaemia. We hypothesized a dose-related effect of hyperoxaemia on left ventricular performance and the vascular properties of the arterial tree.

    Methods: Oscillometrically calibrated arterial subclavian pulse trace data were combined with echocardiographic recordings to obtain non-invasive estimates of left ventricular volumes, aortic root pressure and flow data. For complementary vascular parameters and control purposes whole-body impedance cardiography was applied. In nine (seven males) supine, resting healthy volunteers, aged 23–48 years, data was collected after 15 min of air breathing and at increasing transcutaneous oxygen tensions (20, 40 and 60 kPa), accomplished by a two group, random order and blinded hyperoxemic protocol.

    Results: Left ventricular stroke volume [86 ± 13 to 75 ± 9 mL (mean ± SD)] and end-diastolic area (19.3 ± 4.4 to 16.8 ± 4.3 cm2) declined (P < 0.05), and showed a linear, negative dose–response relationship to increasing arterial oxygen levels in a regression model. Peripheral resistance and characteristic impedance increased in a similar manner. Heart rate, left ventricular fractional area change, end-systolic area, mean arterial pressure, arterial compliance or carbon dioxide levels did not change.

    Conclusion: There is a linear dose–response relationship between arterial oxygen and cardiovascular parameters when the systemic oxygen tension increases above normal. A direct effect of supplemental oxygen on the vessels may therefore not be excluded. Proximal aortic and peripheral resistance increases from hyperoxaemia, but a decrease of venous return implies extra cardiac blood-pooling and compensatory relaxation of the capacitance vessels.

    Deaths caused by injury among people of working age (18-64) are decreasing, while those among older people (64+) are increasing2018In: European Journal of Trauma and Emergency Surgery, ISSN 1863-9933, E-ISSN 1863-9941, Vol. 44, no 4, p. 589-596Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Injury is an important cause of death in all age groups worldwide, and contributes to many losses of human and economic resources. Currently, we know a few data about mortality from injury, particularly among the working population. The aim of the present study was to examine death from injury over a period of 14 years (1999-2012) using the Swedish Cause of Death Registry (CDR) and the National Patient Registry, which have complete national coverage.

    METHOD: CDR was used to identify injury-related deaths among adults (18 years or over) during the years 1999-2012. ICD-10 diagnoses from V01 to X39 were included. The significance of changes over time was analyzed by linear regression.

    RESULTS: The incidence of prehospital death decreased significantly (coefficient -0.22, r (2) = 0.30; p = 0.041) during the study period, while that of deaths in hospital increased significantly (coefficient 0.20, r (2) = 0.75; p < 0.001). Mortality/100,000 person-years in the working age group (18-64 years) decreased significantly (coefficient -0.40, r (2) = 0.37; p = 0.020), mainly as a result of decrease in traffic-related deaths (coefficient -0.34, r (2) = 0.85; p < 0.001). The incidence of deaths from injury among elderly (65 years and older) patients increased because of the increase in falls (coefficient 1.71, r (2) = 0.84; p < 0.001) and poisoning (coefficient 0.13, r (2) = 0.69; p < 0.001).

    CONCLUSION: The epidemiology of injury in Sweden has changed during recent years in that mortality from injury has declined in the working age group and increased among those people 64 years old and over.

    Change in child mortality patterns after injuries in Sweden: a nationwide 14-year study.2017In: European Journal of Trauma and Emergency Surgery, ISSN 1863-9933, E-ISSN 1863-9941, Vol. 43, no 3, p. 343-349Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Sweden has one of the world's lowest child injury mortality rates, but injuries are still the leading cause of death among children. Child injury mortality in the country has been declining, but this decline seems to decrease recently. Our objective was therefore to further examine changes in the mortality of children's death from injury over time and to assess the contribution of various effects on mortality. The underlying hypothesis for this investigation is that the incidence of lethal injuries in children, still is decreasing and that this may be sex specific.

    PATIENTS AND METHODS: We studied all deaths from injury in Sweden under-18-year-olds during the 14 years 1999-2012. We identified those aged under 18 whose underlying cause of death was recorded as International Classification of Diseases, 10th Revision (ICD-10) diagnosis from V01 to X39 in the Swedish cause of death, where all dead citizens are registered.

    RESULTS: From the 1 January 1999 to 31 December 2012, 1213 children under the age of 18 died of injuries in Sweden. The incidence declined during this period (r = -0.606, p = 0.02) to 3.3 deaths/100,000 children-years (95 % CI 2.6-4.2). Death from unintentional injury was more common than that after intentional injury (p < 0.0001). There was a reduction in the incidence of unintentional injuries during the study period (r = -0.757, p = 0.03). The most common causes of death were injury to the brain (n = 337, 41 %), followed by drowning (n = 109, 13 %). The number of deaths after intentional injury increased (r = 0.585, p = 0.03) and at the end of the period was 1.5 deaths/100,000 children-years. The most common causes of death after intentional injuries were asphyxia (n = 177, 45 %), followed by injury to the brain (n = 76, 19 %).

    DISCUSSION: Mortality patterns in injured children in Sweden have changed from being dominated by unintentional injuries to a more equal distribution between unintentional and intentional injuries as well as between sexes and the overall rate has declined further. These findings are important as they might contribute to the preventive work that is being done to further reduce mortality in injured children.

    A prospective dual-centre intra-individual controlled study for the treatment of burns comparing dermis graft with split-thickness skin auto-graft2022In: Scientific Reports, E-ISSN 2045-2322, Vol. 12, no 1, article id 21666Article in journal (Refereed)
    Abstract [en]

    To investigate if donor and recipient site morbidity (healing time and cosmesis) could be reduced by a novel, modified split-thickness skin grafting (STSG) technique using a dermal component in the STSG procedure (DG). The STSG technique has been used for 150 years in surgery with limited improvements. Its drawbacks are well known and relate to donor site morbidity and recipient site cosmetic shortcomings (especially mesh patterns, wound contracture, and scarring). The Dermal graft technique (DG) has emerged as an interesting alternative, which reduces donor site morbidity, increases graft yield, and has the potential to avoid the mesh procedure in the STSG procedure due to its elastic properties. A prospective, dual-centre, intra-individual controlled comparison study. Twenty-one patients received both an unmeshed dermis graft and a regular 1:1.5 meshed STSG. Aesthetic and scar assessments were done using The Patient and Observer Scar Assessment Scale (POSAS) and a Cutometer Dual MPA 580 on both donor and recipient sites. These were also examined histologically for remodelling and scar formation. Dermal graft donor sites and the STSG donor sites healed in 8 and 14 days, respectively (p < 0.005). Patient-reported POSAS showed better values for colour for all three measurements, i.e., 3, 6, and 12 months, and the observers rated both vascularity and pigmentation better on these occasions (p < 0.01). At the recipient site, (n = 21) the mesh patterns were avoided as the DG covered the donor site due to its elastic properties and rendered the meshing procedure unnecessary. Scar formation was seen at the dermal donor and recipient sites after 6 months as in the standard scar healing process. The dermis graft technique, besides potentially rendering a larger graft yield, reduced donor site morbidity, as it healed faster than the standard STSG. Due to its elastic properties, the DG procedure eliminated the meshing requirement (when compared to a 1:1.5 meshed STSG). This promising outcome presented for the DG technique needs to be further explored, especially regarding the elasticity of the dermal graft and its ability to reduce mesh patterns.

    Skin perfusion and oxygen saturation after mastectomy and radiation therapy in breast cancer patients2024In: Breast, ISSN 0960-9776, E-ISSN 1532-3080, Vol. 75, article id 103704Article in journal (Refereed)
    Abstract [en]

    The pathophysiological mechanism behind complications associated with postmastectomy radiotherapy (PMRT) and subsequent implant-based breast reconstruction are not completely understood. The aim of this study was to examine if there is a relationship between PMRT and microvascular perfusion and saturation in the skin after mastectomy and assess if there is impaired responsiveness to a topically applied vasodilator (Methyl nicotinate - MN). Skin microvascular perfusion and oxygenation >2 years after PMRT were measured using white light diffuse reflectance spectroscopy (DRS) and laser Doppler flowmetry (LDF) in the irradiated chest wall of 31 women with the contralateral breast as a control. In the non-irradiated breast, the perfusion after application of MN (median 0.84, 25th-75th centile 0.59-1.02 % RBC × mm/s) was higher compared to the irradiated chest wall (median 0.51, 25th-75th centile 0.21-0.68 % RBC × mm/s, p < 0.001). The same phenomenon was noted for saturation (median 91 %, 25th-75th centile 89-94 % compared to 89 % 25th-75th centile 77-93 %, p = 0.001). Eight of the women (26%) had a ≥10 % difference in skin oxygenation between the non-irradiated breast and the irradiated chest wall. These results indicate that late microvascular changes caused by radiotherapy of the chest wall significantly affect skin perfusion and oxygenation.

    Experimental study of the effects of nitroglycerin, botulinum toxin A, and clopidogrel on bipedicled superficial inferior epigastric artery flap survival.2022In: Scientific Reports, E-ISSN 2045-2322, Vol. 12, no 1, article id 20891Article in journal (Refereed)
    Abstract [en]

    Beneficial effects could be achieved by various agents such as nitroglycerin, botulinum toxin A (BoTA), and clopidogrel to improve skin flap ischaemia and venous congestion injuries. Eighty rats were subjected to either arterial ischaemia or venous congestion and applied to a bipedicled U-shaped superficial inferior epigastric artery (SIEA) flap with the administration of nitroglycerin, BoTA, or clopidogrel treatments. After 7 days, all rats were sacrificed for flap evaluation. Necrotic area percentage was significantly minimized in flaps treated with clopidogrel (24.49%) versus the ischemic flaps (34.78%); while nitroglycerin (19.22%) versus flaps with venous congestion (43.26%). With ischemia, light and electron microscopic assessments revealed that nitroglycerin produced degeneration of keratinocytes and disorganization of collagen fibers. At the same time, with clopidogrel administration, there was an improvement in the integrity of these structures. With venous congestion, nitroglycerin and BoTA treatments mitigated the epidermal and dermal injury; and clopidogrel caused coagulative necrosis. There was a significant increase in tissue gene expression and serum levels of vascular endothelial growth factor (VEGF) in ischemic flaps with BoTA and clopidogrel, nitroglycerin, and BoTA clopidogrel in flaps with venous congestion. With the 3 treatment agents, gene expression levels of tumor necrosis factor-α (TNF-α) were up-regulated in the flaps with ischemia and venous congestion. With all treatment modalities, its serum levels were significantly increased in flaps with venous congestion and significantly decreased in ischemic flaps. Our analyses suggest that the best treatment option for ischemic flaps is clopidogrel, while for flaps with venous congestion are nitroglycerin and BoTA.

    Assessment of Freestyle Local Facial Perforator Flaps for Coverage of Facial Defects2021In: The Journal of Craniofacial Surgery, ISSN 1049-2275, E-ISSN 1536-3732, Vol. 32, no 2, p. e122-e125Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To assess local freestyle facial perforator flaps in the reconstruction of small to medium-sized facial defects.

    MATERIALS AND METHODS: In a case series, local freestyle perforator flaps were used in Suez Canal University Hospital to reconstruct 28 facial defects in 26 patients between 2017 and 2019. Adequate perforators were identified near those defects and flaps were designed as propeller or VY advancement. Four scales from the FACE-Q (satisfaction with facial appearance, satisfaction with the outcome, psychological function, and appearance-related psychosocial distress) and 2 scales from the SCAR-Q (Appearance scale and Symptom scale) were used as well as the observer part of the Patient and Observer Scar Assessment Scale. The mean follow up period was 10 months.

    RESULTS: Complete reconstruction was achieved in all cases with a high rate of patient satisfaction which was assessed by FACE-Q and SCAR-Q. Moreover, observer assessment by Patient and Observer Scar Assessment Scale score showed high patient satisfaction with the scars with a mean (SD) 15.5 (3.4) and there was a positive correlation between subjective and objective: results (r2 from 0.27 to 0.41, P < 0.01). Regarding complications, bulkiness occurred in 2 flaps, congestion in 2 flaps, dehiscence in 1 flap, and tip necrosis in 5 flaps. Accordingly, secondary intervention in the form of medicinal leech therapy was used in 3 flaps, delayed closure for the dehisced flap and debulking for 1 flap.

    CONCLUSIONS: Local freestyle perforator flap reconstruction is one of the recommended techniques for small to medium-sized facial defects which gives a high aesthetic outcome and patient satisfaction.

    Dual Reconstruction of Lumbar and Gluteal Defects with Freestyle Propeller Flap and Muscle Flap2021In: Plastic and Reconstructive Surgery - Global Open, E-ISSN 2169-7574, Vol. 9, no 1, article id e3376Article in journal (Refereed)
    Abstract [en]

    Background: The reconstruction of complex tissue defects in the lumbar and gluteal areas is a surgical challenge. The use of freestyle perforator-based flaps has gained popularity in the reconstruction of these defects due to several advantages: versatility, minimal donor-site morbidity, and tension-free closure. The present study reports the outcome of using a dual coverage of lumbar and gluteal defects with a gluteus maximus rotation flap as a deep layer and a freestyle propeller perforator-based flap as a superficial layer. Methods: A retrospective analysis of 18 patients who had a dual coverage of complex wounds of the lumbar and the gluteal areas was conducted. Different propeller flaps were used as superior gluteal artery perforator flap (SGAP), inferior gluteal artery perforator flap (IGAP), and posterior thigh perforator flap (PTP). Results: The study included 15 men and 3 women. The mean age was 26.3 years. The causes of the defects were: pressure ulcers in 14 patients and post-traumatic in 4 patients. A total of 28 freestyle flaps was used: 11 patients had 1 flap, 4 had 2 flaps, and 3 had 3 flaps. The mean postoperative follow-up was 12.2 months. The complications registered in the medical records were venous congestion in 2 patients, partial flap necrosis in 2 patients, and wound dehiscence in 1 patient. Conclusions: A freestyle propeller perforator-based flap combined with a gluteus maximus muscle flap is a solution that provides well-padding over bony prominence with a low complication rate. However, a long-term follow-up is needed to verify these results. Published online 26 January 2021. Received for publication October 7, 2020; accepted November 23, 2020.

    Laser speckle contrast imaging in children with scalds: Its influence on timing of intervention, duration of healing and care, and costs2019In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 45, no 4, p. 798-804Article in journal (Refereed)
    Abstract [sv]

    Background

    Scalds are the most common type of burn injury in children, and the initial evaluation of burn depth is a problem. Early identification of deep dermal areas that need excision and grafting would save unnecessary visits and stays in hospital. Laser speckle contrast imaging (LSCI) shows promise for the evaluation of this type of burn. The aim of this study was to find out whether perfusion measured with LSCI has an influence on the decision for operation, duration of healing and care period, and costs, in children with scalds.

    Methods

    We studied a group of children with scalds whose wounds were evaluated with LSCI on day 3–4 after injury during the period 2012–2015. Regression (adjustment for percentage total body surface area burned (TBSA%), age, and sex) was used to analyse the significance of associations between degree of perfusion and clinical outcome.

    Results

    We studied 33 children with a mean TBSA% of 6.0 (95% CI 4.4–7.7)%. Lower perfusion values were associated with operation (area under the receiver-operating characteristic curve 0.86, 95% CI 0.73–1.00). The perfusion cut-off with 100% specificity for not undergoing an operation was ≥191 PU units (66.7% sensitivity and 72.7% accurately classified). Multivariable analyses showed that perfusion was independently associated with duration of healing and care period.

    Conclusion

    Lower perfusion values, as measured with LSCI, are associated with longer healing time and longer care period. By earlier identification of burns that will be operated, perfusion measurements may further decrease the duration of care of burns in children with scalds.

    Staged excisions of moderate-sized burns compared with total excision with immediate autograft: an evaluation of two strategies.2017In: International journal of burns and trauma, ISSN 2160-2026, Vol. 7, no 1, p. 6-11Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Different surgical techniques have evolved since excision and autografting became the treatment of choice for deep burns in the 1970s. The treatment plan at the Burn Center, Linköping University Hospital, Sweden, has shifted from single-stage excision and immediate autografting to staged excisions and temporary cover with xenografts before autografting. The aim of this study was to find out if the change in policy resulted in extended duration of hospital stay/total body surface area burned (LOS/TBSA%).

    METHODS: Retrospective clinical cohort including surgically-managed patients with burns of 15%-60% TBSA% within each treatment group. The first had early full excisions of deep dermal and full thickness burns and immediate autografts (1997-98), excision and immediate autograft group) and the second had staged excisions before final autografts using xenografts for temporary cover (2010-11, staged excision group).

    RESULTS: The study included 57 patients with deep dermal and full-thickness burns, 28 of whom had excision and immediate autografting, and 29 of whom had staged excisions with xenografting before final autografting. Adjusted (LOS/TBSA%) was close to 1, and did not differ between groups. Mean operating time for the staged excision group was shorter and the excised area/operation was smaller. The total operating time/TBSA% did not differ between groups.

    CONCLUSION: Staged excisions with temporary cover did not affect adjusted LOS/TBSA% or total operating time. Staged excisions may be thought to be more expensive because of the cost of covering the wound between stages, but this needs to be further investigated as do the factors that predict long term outcome.

    Temporary coverage of burns with a xenograft and sequential excision, compared with total early excision and autograft2016In: Annals of burns and fire disasters, ISSN 1592-9558, Vol. 29, no 3, p. 196-201Article in journal (Refereed)
    Abstract [en]

    During the 80s and 90s, early and total excision of full thickness burns followed by immediate autograft was the most common treatment, with repeated excision and grafting, mostly for failed grafts. It was hypothesized, therefore, that delayed coverage with an autograft preceded by a temporary xenograft after early and sequential smaller excisions would lead to a better wound bed with fewer failed grafts, a smaller donor site, and possibly also a shorter duration of stay in hospital. We carried out a case control study with retrospective analysis from our National Burn Centre registry for the period 1997-2011. Patients who had been managed with early total excision and autograft were compared with those who had had sequential smaller excisions covered with temporary xenografts until the burn was ready for the final autograft. The sequential excision and xenograft group (n=42) required one-third fewer autografts than patients in the total excision and autograft group (n=45), who needed more than one operation (p<0.001). We could not detect any differences in duration of stay in hospital / total body surface area burned% (duration of stay/TBSA%) (2.0 and 1.8) (p=0.83). The two groups showed no major differences in terms of adjusted duration of stay, but our findings suggest that doing early, smaller, sequential excisions using a xenograft for temporary cover can result in shorter operating times, saving us the trouble of making big excisions. However, costs tended to be higher when the burns were > 25% TBSA.

    Skin regeneration in three dimensions, current status, challenges and opportunities2017In: Differentiation, ISSN 0301-4681, E-ISSN 1432-0436, Vol. 96, p. 4p. 26-29Article, review/survey (Refereed)
    Abstract [en]

    Skin regeneration is a life-saving need for many patients, whom list is stretched from burn victims to motor-car accidents. Spraying cells, either keratinocytes or stem cells, were associated with variable results and, in many cases, unfavorable outcomes. As the spatial configuration of the skin is distinctive, many trials investigated the bio-printing or the construction of three dimensional skin models where different layers of the skin were preserved. Although some of these models showed the histological configuration of the skin, their acceptance by the wound was questionable as a consequence of delayed vascularization. In this mini-review, different models for three dimensional regeneration of the skin will be discussed with their main points of strength and challenges as well as their possible opportunities.

    Burn unit design - the missing link for quality and safety.2021In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488, Vol. 42, no 3, p. 369-375Article, review/survey (Refereed)
    Abstract [en]

    The relationship between infrastructure, technology, model of care and human resources influences patient outcomes and safety, staff productivity and satisfaction, retention of personnel, and treatment and social costs. This concept underpins the need for evidence-based design, and has been widely adopted to inform hospital infrastructure planning. The aim of this review is to establish evidence-based, universally-applicable key features of a burn unit that support function in a comprehensive patient-centred model of care. A literature search in medical, architectural and engineering databases was conducted. Burn associations' guidelines and relevant articles published in English, between 1990 and 2020, were included, and the available evidence is summarized in the review. Few studies have been published on burn unit design in the last thirty years. Most of them focus on the role of design in infection control and prevention, and consist primarily of descriptive or observational reports, opportunistic historical cohort studies, and reviews. The evidence available in the literature is not sufficient to create a definitive infrastructure guideline to inform burn unit design, and there are considerable difficulties in creating evidence that will be widely applicable. In the absence of a strong evidence base, consensus guidelines on burn unit infrastructure should be developed, to help healthcare providers, architects and engineers make informed decisions, when designing new or renovated facilities.

    Dynamics of leucocytes correlate with increased pulmonary vascular permeability and decreased PaO2:FiO2 ratio early after major burns2009Manuscript (preprint) (Other academic)
    Abstract [en]

    Introduction: The lung is affected soon after a major burn as indicated by a decreased PaO2:FiO2 ratio. The exact mechanism underlying this is not known. Polymorphonuclear leucocytes (PMN) are activated systemically and their numbers are largely increased soon after a burn followed by a rapid decline to low normal or subnormal numbers within 24 hours, possibly by increased extravasation. Experimental data have supported the hypothesis that an important target for this extravasation is the lungs. Other studies also show that when PMN adhere to endothelial cells they increase vascular permeability, and this effect is mediated, at least in part, by release of heparin binding protein (HBP, also known as CAP-37 and azurocidin). We hypothesised that there is a relation between early increased pulmonary vascular permeability or a decreased PaO2:FiO2 ratio and the dynamic change in blood leucocytes after a burn, possibly mediated by the local release of HBP.

    Material and methods: This is a prospective, descriptive, exploratory, singlecentre study at a national burn centre. We investigated the dynamic changes of leucocytes in blood, plasma concentrations of HBP, pulmonary vascular permeability index (PVPI) by thermodilution, and PaO2:FiO2 ratios in 20 patients during the first 21 days after a major burn (20% >total burn surface area %).

    Results: Median total burn surface area was 40% (IQR 25-52) and full thickness burn 28% (IQR 2-39). There was a correlation between the early (<24 hours) alteration in circulating white blood cell count and both early increased vascular permeability in the lung (r=0.63, p=0.004) and the decreased oxygenation index defined as PaO2:FiO2 < 27 kPa (p=0.004). There were no associations between plasma concentrations of HBP and measured pulmonary vascular permeability or PaO2:FiO2 ratios.

    Conclusions: The results indicate that trapping of leucocytes in the lung may be an important factor in early increased pulmonary vascular permeability and decrease of the PaO2:FiO2 ratio. Our data do not support the idea that HBP, assessed by systemic plasma concentrations, mediate this effect.

    Alteration of Leukocyte Count Correlates With Increased Pulmonary Vascular Permeability and Decreased PaO2:FiO(2) Ratio Early After Major Burns2015In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488, Vol. 36, no 4, p. 484-492Article in journal (Refereed)
    Abstract [en]

    Leukocytes are activated systemically and their numbers increase soon after a burn followed by a rapid decline to low normal or subnormal levels, possibly by increased extravasation. Experimental data support that an important target for such extravasation is the lungs and that leukocytes when they adhere to endothelial cells cause an increase in vascular permeability. The authors investigated a possible relation between early increased pulmonary vascular permeability or a decreased PaO2:FiO(2) ratio and the dynamic change in concentration of blood leukocytes after a burn. This is a prospective, exploratory, single-center study. The authors measured the dynamic changes of leukocytes in blood starting early after the burn, pulmonary vascular permeability index by thermodilution, and PaO2:FiO(2)-ratios in 20 patients during the first 21 days after a major burn (greater than20% TBSA%). Median TBSA was 40% interquartile range (IQR, 25-52) and full thickness burn 28% (IQR, 2-39). There was a correlation between the early (less than24 hours) alteration in white blood cell count and both early increased pulmonary vascular permeability (r = .63, P = .004) and the decreased oxygenation index defined as PaO2:FiO(2) less than 27 kPa (P = .004). The authors have documented a correlation between dynamic change of blood leukocytes and pulmonary failure early after burns.

    Scarring At Donor Sites After Split-Thickness Skin Graft: A Prospective, Longitudinal, Randomized Trial2018In: Advances in Skin & Wound Care, ISSN 1527-7941, E-ISSN 1538-8654, Vol. 3, no 4, p. 183-188Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of this study was to evaluate scarring at split-thickness skin graft donor sites 8 years after surgery.

    METHODS: At surgery, 67 patients were randomized to hydrofiber, polyurethane foam, or porcine xenograft treatment. Scars were evaluated with the Patient and Observer Scar Assessment Scale.

    RESULTS: Results showed significant differences in observed scar outcomes at donor sites, leaving the polyurethane foam–treated and the porcine xenograft–treated patients with the least satisfying scars. Multivariable regression analysis showed that the group treated with the xenografts had worse scores for overall opinion of the scar than did the other groups (P = .03), the most important factor being pigmentation. There was no correlation between duration of healing time and quality of the scar.

    CONCLUSIONS: There were significant differences among the groups, with the hydrofiber group being the most satisfied with the appearance of their scar.

    Scarring at Donor Sites after Split-Thickness Skin Graft: A Prospective, Longitudinal, Randomized Trial2020In: Advances in Skin & Wound Care, ISSN 1527-7941, E-ISSN 1538-8654, Vol. 33, no 12Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To investigate if previous findings on the association between dressing treatments and subjective opinion on final donor site scar outcome using the Patient and Observer Scar Assessment Scale (POSAS) can be confirmed objectively. The previous study showed that patients dressed with hydrofiber covered with film were more satisfied with their donor site scars than patients receiving porcine xenograft or polyurethane foam dressings. METHODS: Scar outcome measurements were assessed by a blinded observer using POSAS and the Cutometer dual MPA 580 device to measure the viscoelasticity of skin. RESULTS: A total of 17 participants were included in this study, five of whom were treated with hydrofiber, six with polyurethane foam, and another six with porcine xenograft. There were no significant differences among groups in any of the POSAS items or in the viscoelasticity measurements made with the Cutometer. CONCLUSIONS: The investigators could not confirm previous associations between dressing treatment and long-term donor site scars. No associations between donor sites healing times and final scarring were found. Hypopigmentation was reported in 15 of 17 donor sites evaluated.

    Suprathel® or Mepilex® Ag for treatment of partial thickness burns in children: A case control study2023In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 49, no 7, p. 1585-1591Article in journal (Refereed)
    Abstract [en]

    Aim

    The study aim was to investigate if Suprathel® can be an adequate alternative to Mepilex® Ag for the treatment of partial-thickness scalds in children.

    Methods

    A retrospective study including 58 children admitted to The Burn Centre in Linköping, Sweden between year 2015 and 2022. Of the 58 children, 30 were dressed with Suprathel ® and 28 with Mepilex ® Ag. Outcomes investigated were healing time, burn wound infection (BWI), need for operations and number of dressing changes.

    Results

    We found no significant differences in any of the outcomes. In the Suprathel ® group 17 children and in the Mepilex ® Ag group 15 children were healed within 14 days. Ten children from each group received antibiotics for suspected BWI and two from each group underwent an operation with skin grafting. Each group had on median four dressing changes.

    Conclusions

    Two different treatments were compared for children with partial-thickness scalds, and the data indicates that similar results are received with both dressings.

    Sprayed cultured autologous keratinocytes in the treatment of severe burns: a retrospective matched cohort study.2020In: Annals of burns and fire disasters, ISSN 1592-9558, Vol. 33, no 2, p. 134-142Article in journal (Refereed)
    Abstract [en]

    The standard treatment of burns is early excision followed by autologous skin grafting. The closure of extensive deep burns poses a considerable challenge. Cultured autologous keratinocytes have been used since 1981 in an effort to improve healing. However, the time required to culture the cells and the lack of a dermal component limit the expectations of outcome. Our aim was to compare the duration of hospital stay between patients who were treated with autologous skin grafts and cultured autologous keratinocytes and those who were treated with autologous skin grafting without cultured autologous keratinocytes. In this retrospective study all patients treated with cultured autologous keratinocytes between 2012 and 2015 were matched by size and depth of burn with patients not treated with cultured autologous keratinocytes. Multivariable regression was used to analyse associations between duration of hospital stay and treatment adjusted for age, mortality, size and depth of the burn. Then, we investigated the possibility of differentiation of human bone marrow stem cell line to keratinocyte- like cells as a future direction. The regression analysis showed a coefficient of 17.36 (95% CI -17.69 to 52.40), p= 0.32, for hospital stay in the treatment group, compared with the matched group. Our results showed no difference in the duration of hospital stay between the two treatments. Autologous stem cells should be considered as a future modality of burn management, although further studies are needed.

    Burn scar outcome at six and 12 months after injury in children with partial thickness scalds: Effects of dressing treatment.2020In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 46, no 3, p. 546-551, article id S0305-4179(19)30714-4Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: In line with other researchers in the field of burns' care, we think that research investigating the long-term outcome of scars is largely lacking. As scarring is of the utmost importance to the patient, clinicians who treat burns must aim to find treatments that lead to a good end result. The aim of this study was to study scar outcomes at six and 12 months after injury. It is an extension of a previous randomised controlled trial (RCT) in which two dressings (porcine xenograft and silver foam dressing) were examined with respect to their ability to help heal partial thickness scalds.

    METHOD: Children aged six months - six years with acute partial thickness scalds, on the trunk, or extremities, or both, were included. In the previous study, the silver foam was found to have significantly shorter healing times than the xenograft. Children were assessed at six and 12 months after injury for this study, and photographs were taken of the burn site, and both the patient and observer scar assessment scale (POSAS) and the Vancouver scar scale (VSS) were completed and evaluated by blinded observers.

    RESULTS: Of the 58 children from the original RCT, 39 returned to the clinic for evaluation of their scars at six months, and 34 at 12 months after injury. There were no differences in POSAS, VSS total scores, or incidence of hypertrophic scarring between the different dressings. Fifteen children were assessed as having hypertrophic scarring, all of whom had healing times that had extended beyond 14 days.

    CONCLUSIONS: This study compared burn scarring after two different treatments for burns in children with partial-thickness scalds and the data suggested that neither dressing had a more favourable impact on scar outcome. The conclusion is, however, tempered by the non-return of all the patients to the follow up. However, as anticipated, regardless of the dressing used, longer healing times were associated with higher scar scores (more scarring) and hypertrophic scarring.

    Wound infection among children with moderate burns – An explorative review of the association between reported frequency and diagnosis2023In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 50, no 3, p. 742-753Article in journal (Refereed)
    Abstract [en]

    Introduction: The Linkoping burn centre in Sweden has, even though being a high income country, reported high burn wound infections (BWI) frequencies in scalded children compared to similar populations in other parts of the world.

    Aim: The aim was to investigate possible explanations for differences in frequency of BWI among children with partial thickness burns treated at the Linköping burn centre in Sweden, and that reported in other studies.

    Method: In order to investigate what BWI criteria that were used in similar studies a literature search on PubMed Central was done along with a retrospective analysis of children previously diagnosed as infected to confirm or reject the high infection frequency reported earlier.

    Result: Of the 34 selected publications reporting on BWI frequency 16 (47%) did not define a criteria for the BWI diagnosis and almost a third did not report on wound culturing. Of those who did report the use a third do not mention any bacterial growth found is these cultures. The retrospective analysis on children at the centre did not show any decrease in infection frequency even with some disagreement on onset for the BWI.

    Conclusion: The reporting of criteria and diagnosis of burn wound infection is highly variable making it difficult to interpret results and come to conclusions. The high frequency of BWI at the centre might be a result of close monitoring due to study participation, use of clean instead of sterile routine at dressing changes or low thresholds for the diagnosis in respect to changes in infection markers.

    Xeno-free workflow exhibits comparable efficiency and quality of keratinocytes isolated from human skin biopsies2021In: Regenerative Therapy, ISSN 2352-3204, Vol. 18, p. 401-407Article in journal (Refereed)
    Abstract [en]

    Introduction Regenerative solutions of the skin represent a hope for burn victims with extensive skin loss and chronic wound patients. The development of xeno-free workflow is crucial for clinical application in compliance with the directives of the European Medicines Agency. This study aimed at evaluating the outcome of the xeno-free isolation workflow of keratinocytes from human skin biopsy. Methods Skin biopsies were obtained from volunteers. The epidermis was digested with TrypLE™ Select, which was deactivated by dilution or with trypsin, deactivated by media with fetal bovine serum. Freshly isolated cells were compared for total cell number, viability, activity of caspase 3, gene expression and the presence of the keratinocyte surface markers cytokeratin 14. The cells were cultured in xeno-free conditions for one week and characterized regarding the number and viability as well as the metalloproteinase secretion. Results The number of obtained cells was similar in both workflows. The cell viability was less in the TrypLE group, with slight reduction of the cell surface marker cytokeratin 14. Caspase 3 activity was comparable as well as the gene expression of the apoptotic markers BAX, BCL2 and SLUG, as well as the keratinocyte markers cytokeratin 14, stratifin and filaggrin. Upon culture, the number of keratinocytes, their viability and secretion of matrix metalloproteinases 1 and 10 were equal in both groups. Conclusion This study reports the possibility of isolating functioning and viable keratinocytes through a xeno-free workflow for clinical application.

    Decreased risk adjusted 30-day mortality for hospital admitted injuries: a multi-centre longitudinal study2018In: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, E-ISSN 1757-7241, Vol. 26, no 1, article id 24Article in journal (Refereed)
    Abstract [en]

    Background: The interpretation of changes in injury-related mortality over time requires an understanding of changes in the incidence of the various types of injury, and adjustment for their severity. Our aim was to investigate changes over time in incidence of hospital admission for injuries caused by falls, traffic incidents, or assaults, and to assess the risk-adjusted short-term mortality for these patients.less thanbr /greater thanMethods: All patients admitted to hospital with injuries caused by falls, traffic incidents, or assaults during the years 2001-11 in Sweden were identified from the nationwide population-based Patient Registry. The trend in mortality over time for each cause of injury was adjusted for age, sex, comorbidity and severity of injury as classified from the International Classification of diseases, version 10 Injury Severity Score (ICISS).less thanbr /greater thanResults: Both the incidence of fall (689 to 636/100000 inhabitants: p = 0.047, coefficient - 4.71) and traffic related injuries (169 to 123/100000 inhabitants: p less than 0.0001, coefficient - 5.37) decreased over time while incidence of assault related injuries remained essentially unchanged during the study period. There was an overall decrease in risk-adjusted 30-day mortality in all three groups (OR 1.00; CI95% 0.99-1.00). Decreases in traffic (OR 0.95; 95% CI 0.93 to 0.97) and assault (OR 0.93; 95% CI 0.87 to 0.99) related injuries was significant whereas falls were not during this 11-year period.less thanbr /greater thanDiscussion: Risk-adjustment is a good way to use big materials to find epidemiological changes. However after adjusting for age, year, sex and risk we find that a possible factor is left in the pre- and/or in-hospital care.less thanbr /greater thanConclusions: The decrease in risk-adjusted mortality may suggest changes over time in pre- and/or in-hospital care. A non-significantdecrease in risk-adjusted mortality was registered for falls, which may indicate that low-energy trauma has not benefited for the increased survivability as much as high-energy trauma, ie traffic- and assault related injuries.

    Female risk-adjusted survival advantage after injuries caused by falls, traffic or assault: a nationwide 11-year study2019In: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, E-ISSN 1757-7241, Vol. 27, no 1, article id 24Article in journal (Refereed)
    Abstract [en]

    Background: A female survival advantage after injury has been observed, and animal models of trauma have suggested either hormonal or genetic mechanisms as component causes. Our aim was to compare age and riskadjusted sex-related mortality in hospital for the three most common mechanisms of injury in relation to hormonal effects as seen by age.

    Methods: All hospital admissions for injury in Sweden during the period 2001–2011 were retrieved from the National Patient Registry and linked to the Cause of Death Registry. The International Classification of Diseases Injury Severity Score (ICISS) was used to adjust for injury severity, and the Charlson Comorbidity Index to adjust for comorbidity. Age categories (0–14, 15–50, and ≥ 51 years) were used to represent pre-menarche, reproductive and post- menopausal women.

    Results: Women had overall a survival benefit (OR 0.51; 95% CI 0.50 to 0.53) after adjustment for injury severity and comorbidity. A similar pattern was seen across the age categories (0–14 years OR 0.56 (95% CI 0.25 to 1.25), 15–50 years OR 0.70 (95% CI 0.57 to 0.87), and ≥ 51 years OR 0.49 (95% CI 0.48 to 0.51)).

    Conclusion: In this 11-year population-based study we found no support for an oestrogen-related mechanism to explain the survival advantage for females compared to males following hospitalisation for injury.

    Children aged 0-16 admitted to Swedish intensive care units and paediatric intensive care units showed low mortality rates.2019In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 108, no 8, p. 1460-1466Article in journal (Refereed)
    Abstract [en]

    AIM: This study described the basic characteristics of children aged 0-16 years who were treated in intensive care units (ICUs) and paediatric ICUs (PICUs), compared their outcomes and examined any causes of death.

    METHODS: This was a retrospective cohort study of admissions to 74 ICUs and three PICUs in Sweden that were recorded in the Swedish Intensive Care Registry from January 1, 2008 to December 31, 2012.

    RESULTS: We retrieved data on 12 756 children who were admitted 17 003 times. The case mix differed between the ICUs, which were mainly admissions for injuries, accidents and observation, and PICUs, which were mainly admissions for malformations, genetic abnormalities and respiratory problems (p < 0.001). The median stays in the ICUs and PICUs were 1.4 and 3.5 days (p < 0.001), respectively. The respective crude mortality rates were 1.1% and 2.0, and the Paediatric Index of Mortality version 2 standardised mortality ratios were 0.43 and 0.50. None of these differences were significant. Most deaths were within 24 hours: About 57% in the ICUs, mainly from brain anomalies, and 13% in the PICUs, mainly from circulatory problems.

    CONCLUSION: Sweden had a low mortality rate in both ICUs and PICUs and the children admitted to these two types of unit differed.

    Patient controlled sedation using a standard protocol for dressing changes in burns: Patients' preference, procedural details and a preliminary safety evaluation2008In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 34, no 7, p. 929-934Article in journal (Refereed)
    Abstract [en]

    Background: Patient controlled sedation (PCS) enables patients to titrate doses of drugs by themselves during different procedures involving pain or discomfort. Methods: We studied it in a prospective crossover design using a fixed protocol without lockout time to examine it as an alternative method of sedation for changing dressings in burned patients. Eleven patients with >10% total burn surface area (TBSA) had their dressings changed, starting with sedation by an anaesthetist (ACS). The second dressing change was done with PCS (propofol/alfentanil) and the third time the patients had to choose ACS or PCS. During the procedures, data on cardiopulmonary variables, sedation (bispectral index), pain intensity (VAS), procedural details, doses of drugs, and patients' preferences were collected to compare the two sedation techniques. Results: The study data indicated that wound care in burned patients is feasible with a standardized PCS protocol. The patients preferred PCS to ACS on the basis of self-control, and because they had less discomfort during the recovery period. Wound care was also considered adequate by the staff during PCS. No respiratory (respiratory rate/transcutaneous PCO2) or cardiovascular (heart rate/blood pressure) adverse events were recorded at any time during any of the PCS procedures. The doses of propofol and alfentanil and BIS index decrease were less during PCS than ACS. Procedural pain was higher during PCS but lower after the procedure. Conclusion: We suggest that PCS using a standard protocol is an interesting alternative to anaesthetist-provided sedation during dressing changes. It seems effective, saves resources, is safe, and at same time is preferred by the patients. The strength of these conclusions is, however, hampered by the small size of this investigation and therefore further studies are warranted. © 2008 Elsevier Ltd and ISBI.

    Flap Survival after Reconstructive Surgery for Pressure Ulcers: A Cohort Study2023In: Plastic and Reconstructive Surgery - Global Open, E-ISSN 2169-7574, Vol. 11, no 12, p. e5451-e5451Article in journal (Refereed)
    Abstract [en]

    Background: Pressure ulcers are troublesome for patients and require considerable resources to resolve. Previous studies have focused on recurrence, whereas there are few studies on flap survival. The aim was to describe the group and to analyze possible factors for flap survival.

    Method: A descriptive retrospective analysis of all operations between 2008 and 2020 was carried out. Flap survival at 40 days was assessed. A flap was classified as a failure if a reoperation with removal or replacement was planned before, or in connection with, the first return visit. Variables of patient demographics, details of the pressure ulcers, and surgical treatment and care were analyzed with multivariable logistic regression for their effect on flap survival.

    Results: A total of 111 flaps were included [78 (70%) with random blood supply and 33 (30%) with axial or perforator-based blood supply]; 54 (49%) of the flaps were fasciocutaneous. Body mass index was 25 (IQR 22–28). Flap survival rate was 90%. Variables associated with flap failure were higher body mass index, congenital spinal cord injury, type of blood supply to the flap, and the use of methylene blue to guide debridement of the wound.

    Conclusions: The findings show factors that can be modified to improve future results, including a normalized body mass index and use of methylene blue in surgery to outline wound edges and depth, as this has been shown to protect against flap failure. Our data suggest that random flaps, such as V-Y, are preferable to axial flaps in the studied group.

    Patient Reported Experiences at a Swedish National Burn Centre2022In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488, Vol. 43, no 1, p. 249-254Article in journal (Refereed)
    Abstract [en]

    Previous studies have shown that burn patients were satisfied with the received care. Satisfaction was not strongly associated to burns or to psycho-social characteristics, suggesting that other factors, related to burn care specific aspects, may be important. The aim of this study was to analyze the independent effect of provided workload on the general satisfaction in adult patients at a Swedish national Burn Centre. The study population (n = 122) included patients ≥18 years, treated at the Linköping Burn Centre between 2016 and 2017. Experienced burn care was evaluated with the PS-RESKA survey (score range: 0-4), and provided workload was scored with the Burn Scoring System (BSC). Groups were compared with χ 2 test, MW test, or Fisher´s exact test. Multivariable logistic regression analyzed the independent effect of BSC on the outcome High Satisfaction (= score ≥3 to the survey-question: "How would you score your global experience at the Burn Centre?"). In-patients (n = 60) had more often larger burns and required more workload than out-patients (median[IQR]: TBSA% = 6.3 [3-12.3] % vs. 0.7 [0.3-2] %, p < .001; BSC = 65 [25.5-135.5] vs. 6 [4-9], p < .001). Both groups were highly satisfied with the experienced care (mean score [SD] = 3.68 [0.57] vs. 3.41 [0.77], p = .03). Neither characteristics of the patients (age, sex), nor TBSA% nor provided workload (BSC) were independently associated with High Satisfaction. Regardless of burn severity, demographics and provided workload, adult patients with burns were highly satisfied with the experienced burn care. This finding suggested that the reason of the satisfaction was multifactorial.

    Are there any differences in the provided burn care between men and women? A retrospective study2018In: Burns & Trauma, E-ISSN 2321-3876, Vol. 6, article id 22Article in journal (Refereed)
    Abstract [en]

    Background

    Disparity between medical treatment for men and women has been recorded worldwide. However, it is difficult to find out if the disparities in both the use of resources and outcome depend entirely on sex-related discrimination. Our aim was to investigate if there are differences in burn treatments between the sexes.

    Methods

    All patients admitted with burns to Linköping University Hospital during the 16-year period 2000–2015 were included. Interventions were prospectively recorded using the validated Burn SCoring system (BSC). Data were analysed using a multivariable panel regression model adjusted for age, percentage total body surface area (%TBSA), and in-hospital mortality.

    Results

    A total of 1363 patients were included, who generated a total of 22,301 daily recordings while they were inpatients. Males were 70% (930/1363). Sex was not an independent factor for daily scores after adjustment for age, %TBSA, and mortality in hospital (model R2=0.60, p < 0.001).

    Conclusion

    We found no evidence of inequity between the sexes in treatments given in our burn centre when we had adjusted for size of burn, age, and mortality. BSC seems to be an appropriate model in which to evaluate sex-related differences in the delivery of treatments.

    Self-inflicted burns in a National Swedish Burn Centre [BRÛLURES VOLONTAIRES DANS UN CTB SUÉDOIS]: an overview [REVUE D’UNE SÉRIE]2019In: Annals of burns and fire disasters, ISSN 1592-9558, Vol. 32, no 4, p. 272-277Article in journal (Refereed)
    Abstract [en]

    In the Western world, self-inflicted burns are often associated with mental health disorders, and the management, particularly the pain treatment, can often be complicated by the psycho-social background of the patients. The aim was to describe a group of patients with self-inflicted burns by analysing their in-hospital mortality and the use of sedation during procedures. All patients with self-inflicted burns admitted to the Linköping Burn Centre during 2000-2017 were included. The control group consisted of adults (≥17 years) with accidental burns, admitted during the same period. Multivariable logistic and linear regression was used for analysis. Three percent of all patients (47/1601) had self-inflicted burns: most of them were men (60%, 28/47), none was younger than 17 years, and flame was the major cause of injury. Self-inflicted burn patients were younger and had larger burns: mean age (SD) was 42 (16) and 49 (20) years, respectively; mean TBSA (SD) was 29% (26) and 14% (17), respectively. The crude rate of procedures done under sedation was higher (mean (SD) 0.37 (0.23) compared with 0.24 (0.25)) as was crude in-hospital mortality (8/47, 17% compared with 72/1018, 7%). Multivariable analyses showed no difference in the use of sedation for procedures or in-hospital mortality after adjustment for TBSA%, full thickness burns, age and sex. Age and TBSA% were associated with in-hospital mortality, whereas the intentionality of the burn was not. TBSA% and female sex were associated with increased use of sedation for wound care procedures, whereas self-inflicted burns were not.

    Burned patients who die from causes other than the burn affect the model used to predict mortality: a national exploratory study2018In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 44, no 2, p. 280-287Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: The Baux score - the sum of age and total body surface area burned (TBSA %) - is a good predictor of mortality has a high specificity but low sensitivity. Our aim was to examine the causes of death in patients who die with Baux scores of <100, which may explain the lower sensitivity and possibly affect the prediction of mortality.

    METHODS: All patients admitted to our centre for burn care from 1993 to 2015 (n=1946) were included in this retrospective, descriptive, exploratory study. The study group comprised those patients who died with Baux scores of <100 (n=23), and their medical charts were examined for the cause of death and for coexisting diseases.

    RESULTS: Crude mortality was 5% (93/1946) for the overall cohort, and a quarter of the patients who died (23/93) had Baux scores of less than 100 (range 64-99). In this latter group, flame burns were the most common (18/23), the median (10th-90th centile) age was 70 (46-86) years and for TBSA 21 (5.0-40.5) %, of which 7 (0-27.0) % of the area was full thickness. The main causes of death in 17 of the 23 were classified as "other than burn", being cerebral disease (n=9), cardiovascular disease (n=6), and respiratory failure (n=2). Among the remaining six (burn-related) deaths, multiple organ failure (predominantly renal failure) was responsible. When we excluded the cases in which the cause of death was not related to the burn, the Baux mortality prediction value improved (receiver operating characteristics area under the curve, AUC) from 0.9733 (95% CI 0.9633-0.9834) to 0.9888 (95% CI 0.9839-0.9936) and the sensitivity estimate increased from 45.2% to 53.9%.

    CONCLUSION: Patients with burns who died with a Baux score <100 were a quarter of all the patients who died. An important finding is that most of these deaths were caused by reasons other than the burn, usually cerebrovascular disease. This may be the explanation why the sensitivity of the Baux score is low, as factors other than age and TBSA % explain the fatal outcome.

    Inclusion of coexisting morbidity in a TBSA% and age based model for the prediction of mortality after burns does not increase its predictive power2015In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 41, no 8, p. 1868-1876Article in journal (Refereed)
    Abstract [en]

    Introduction: Several models for predicting mortality have been developed for patients with burns, and the most commonly used are based on age and total body surface area (TBSA%). They often show good predictive precision as depicted by high values for area under the receiver operating characteristic curves (AUC). However the effect of coexisting morbidity on such prediction models has not to our knowledge been thoroughly examined. We hypothesised that adding it to a previously published model (based on age, TBSA%, full thickness burns, gender, and need for mechanical ventilation) would further improve its predictive power. Methods: We studied 772 patients admitted during the period 1997-2008 to the Linkoping University Hospital, National Burn Centre with any type of burns. We defined coexisting morbidity as any of the medical conditions listed in the Charlson list, as well as psychiatric disorders or drug or alcohol misuse. We added coexisting medical conditions to the model for predicting mortality (age, TBSA%, and need for mechanical ventilation) to determine whether it improved the model as assessed by changes in deviances between the models. Results: Mean (SD) age and TBSA% was 35 (26) years and 13 (17) %, respectively. Among 725 patients who survived, 105 (14%) had one or more coexisting condition, compared with 28 (60%) among those 47 who died. The presence of coexisting conditions increased with age (p &lt; 0.001) among patients with burns. The AUC of the mortality prediction model in this study, based on the variables age, TBSA%, and need for mechanical ventilation was 0.980 (n = 772); after inclusion of coexisting morbidity in the model, the AUC improved only marginally, to 0.986. The model was not significantly better either. Conclusion: Adding coexisting morbidity to a model for prediction of mortality after a burn based on age, TBSA%, and the need for mechanical ventilation did not significantly improve its predictive value. This is probably because coexisting morbidity is automatically adjusted for by age in the original model. (C) 2015 Elsevier Ltd and ISBI. All rights reserved.

    N-Terminal Brain Natriuretic Peptide First Week After Burn Injury2018In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488, Vol. 39, no 5, p. 805-810Article in journal (Refereed)
    Abstract [en]

    B-type natriuretic peptide has shown promising results as a biomarker for acute kidney injury in general intensive care patients. It may also indirectly reflect fluid balance of the circulation. Among burn patients, it has been observed to indicate excessive fluid resuscitation and organ dysfunction, although its clinical use to indicate acute kidney injury or guide fluid resuscitation has not been validated. The aim of this study was to evaluate whether the N-terminal pro-brain natriuretic peptide values are related to the amount of fluids given after severe burn injury and whether it can act as a novel biomarker for acute kidney injury in these patients. Nineteen consecutive burn patients were included. Plasma N-terminal pro-brain natriuretic peptide was measured daily during 1 week from admission. Other variables such as laboratory values and intravenous infusions were also recorded. The association between acute kidney injury and N-terminal pro-brain natriuretic peptide values was analyzed with a multivariable panel regression model, adjusted for burned total body surface area, age, body mass index, and laboratory values. N-terminal pro-brain natriuretic peptide values varied between single patients, and even more between the patients who developed acute kidney injury. Older age, lower body mass index, and cumulative infusions were independently associated with higher N-terminal pro-brain natriuretic peptide values, whereas acute ki
