Abstract [en]

Introduction and hypothesisHow body mass index (BMI) affects pelvic floor function after a second-degree perineal laceration is unknown. The hypothesis of this study is that pelvic floor dysfunction and complications after an obstetric second-degree perineal laceration are more common in women with a higher BMI 8 weeks postpartum.MethodsThis register-based cohort study includes 10,876 primiparous women with an obstetric second-degree perineal laceration between 2014 and 2021. Data were retrieved from the Swedish Perineal Laceration Registry. Outcomes in relation to maternal BMI were urinary incontinence (UI), anal incontinence (AI) and common complications attributable to the laceration. Uni- and multivariate logistic regressions were used for comparison between normal weight (BMI < 24.9, reference), overweight (25.0-29.9) and obese (& GE; 30) women.ResultsMultivariate analyses showed an increased risk for UI in both overweight and obese women compared to normal-weight women 8 weeks after a second-degree perineal laceration with an adjusted odds ratio (aOR) of 1.21 (CI 1.02-1.44) and 1.27 (CI 1.13-1.58) respectively. Overweight and obese women had a decreased risk for AI (aOR 0.81, CI 0.68-0.96; aOR 0.72, CI 0.57-0.90 respectively) compared with normal-weight women. No significant differences were found in the univariate analyses over BMI strata concerning complications after perineal laceration.ConclusionsPrimiparous overweight and obese women report less AI and more UI than normal-weight women 8 weeks after a second-degree perineal laceration. No differences were found regarding complications. These findings are new and merit further study to find potential preventive factors and interventions after a second-degree perineal laceration.

Abstract [en]

Objectives: This study aimed to determine the association between the total cumulative oxytocin dose during labour and adverse postpartum outcomes, childbirth experience and breastfeeding in term primiparous women with spontaneous onset of labour.

Study design: A prospective observational multicentre study, including 1395 women with spontaneous labour, in seven hospitals in Southeast Sweden. Multivariable logistic regression (Crude Odds Ratios (OR) and adjusted OR (aOR) for relevant confounders) was used to analyze the association between oxytocin dose and postpartum outcomes. The exposure was the cumulative oxytocin dose during labour, classified in percentiles (<25th, 25-75th, >75th). The outcomes were occurrence of obstetric anal sphincter injury, postpartum haemorrhage (blood loss > 1000 ml), Apgar score < 7 at five minutes, umbilical cord arterial pH, postpartum bladder overdistension, exclusive breastfeeding at one week and three months, and the woman’s perceived birth experience.

Results: Women receiving high amounts (>75th percentile, >4370 mU) of oxytocin infusion during labour had an increased risk of postpartum haemorrhage (OR 2.73 (1.78–4.19)), an overdistended bladder (OR 2.19 (1.11–4.31)), an infant with an Apgar score < 7 at five minutes (OR 2.89 (1.27–6.57)), a negative birth experience (OR 1.83 (1.25–2.69)), and a decreased chance of exclusive breastfeeding at one week (OR 0.63 (0.41–0.96)). After adjusting for confounders, all outcomes remained statistically significant except risk of low Apgar score and chance of exclusive breastfeeding.

Conclusion: In women with high cumulative oxytocin dose during labour prompt, and prophylactic administration of uterotonics after delivery of the placenta should be considered to reduce the risk of postpartum haemorrhage. The risk for bladder overdistension can be reduced by implementing routines for observation for signs of bladder filling in the early postpartum period, as well as routine use of bladder scans post micturition to assess for successful bladder emptying. As women’s birth experience have a major impact on their future mental health, should be routinely assessed postpartum, and support should be offered to women with negative experiences.

Abstract [en]

Introduction: Postpartum hemorrhage is the leading cause of maternal morbidity and mortality worldwide. There are several known risk factors for postpartum hemorrhage related to pregnancy and delivery, but less evidence of predisposing factors. Recent research has shown that vitamin D deficiency may increase the risk of cesarean section due to dystocia, based on its effect on striated muscle as well as possible effect on the myometrium. Whether vitamin D deficiency increases the risk for postpartum hemorrhage and especially atonic hemorrhage is unknown.Material and methods; This was a retrospective translational study. The study population included 1367 women in Sweden and the main exposure was the serum concentration of 25-hydroxylated vitamin D at time of delivery. The LIASON (R) 25 OH vitamin D total assay method was used for analyzing 25-hydroxylated vitamin D. Vitamin D insufficiency was defined as serum concentration &lt;50 nmol/L and vitamin D deficiency as serum concentrations &lt;25 nmol/L. Primary outcomes were postpartum hemorrhage and severe postpartum hemorrhage defined as bleeding &gt;= 500 mL and &gt;= 1000 mL, respectively 2 h after delivery. Secondary outcome was atonic postpartum hemorrhage. Crude and adjusted odds ratios were calculated with 95% confidence intervals using univariable and multivariable logistic regression. Three different adjustment methods were used, adjusting for maternal, obstetrical and neonatal confounders.Results; Postpartum hemorrhage and severe postpartum hemorrhage afflicted 31.3% and 6.4% of the women, respectively. Rate of atonic postpartum hemorrhage was 21% in the whole population. Rate of vitamin D insufficiency and deficiency was 57%. Vitamin D insufficiency or deficiency was neither found to be associated with postpartum hemorrhage, nor with atonic postpartum hemorrhage.Conclusions: In this study, the vitamin D status of women at the time of delivery was not a predictor of postpartum hemorrhage overall or atonic postpartum hemorrhage.

Abstract [en]

Introduction and hypothesis The impact of body mass index (BMI) on pelvic floor recovery after an obstetric anal sphincter injury (OASI) is unclear. The aim of this study was to evaluate the hypothesis that urinary incontinence (UI) and anal incontinence (AI) are more common in overweight and obese women than in normal-weight women 8 weeks postpartum in women with OASI. Methods A population-based cohort study including 6,595 primiparous women, with an OASI, delivered between 2014 and 2019. Exposure and questionnaire data were retrieved from the Swedish Perineal Laceration Registry. Uni- and multivariate analyses were used to compare normal-weight (BMI &lt;= 24.9, reference), overweight (25.0-29.9), and obese (&gt;= 30) women with regard to UI and AI at 8 weeks post-partum. Results Multivariate analyses showed an increased risk for urinary incontinence (OR 1.54, 95% CI 1.27-1.87) among overweight women as well as among obese women (OR 1.72, 95% CI 1.32-2.24). In contrast to our hypothesis, both overweight women (OR 0.68, 95% CI 0.56-0.83) and obese women (OR 0.65, 95% CI 0.49-0.87) were at a decreased risk for any gas and/or faecal incontinence after adjustment to possible confounding factors. The absolute rate of AI was 40.1% among normal-weight women, 34.2% among overweight women, and 29.1% in the obese group. Conclusions Urinary incontinence is more common, whereas AI is less common among overweight and obese women than in primiparous women with a BMI &lt;24.9, 8 weeks after an OASI. The new finding, that overweight women report less AI than normal-weight women, merits further study.

Abstract [en]

This paper explains how simulation-based continuing professional education can enable professionals to overcome significant challenges in healthcare practice. It focuses on pedagogies that address conflicts of motives experienced by teams at work by promoting collective use of protocols and an auxiliary motive to collaborate in agile, relational practices. Data relating to a simulation programme (PROBE) associated with reduced injuries in emergency birth situations are examined. The concept of double stimulation informs analysis of simulated scenarios and linked debriefs. PROBE transforms a commonly used protocol from a memory tool used by individuals to an ‘in-between’ tool used expansively and collectively across the birthing team. Crucial to this are diverse epistemic levels of mediation that enable teams to resolve conflicted, high-stakes situations through fluid, responsive interactions. Indications in the data that PROBE pedagogies foster transformative agency among health professionals are highlighted and discussed. The paper thus adds to understanding of how double stimulation as a principle of volitional action can be put to work in continuing professional education.

Abstract [en]

Introduction

The nine‐item list, with organizational and cultural changes, was implemented at the delivery unit in Linköping, Sweden between 2007 and 2010, aiming at improving the quality of care by offering more women a safe and attractive vaginal delivery. The target group for the intervention was nulliparous women at term with spontaneous onset of labor and cephalic presentation (Robson group 1). The aim of this study was to evaluate pregnancy outcomes before, during, early post and late post introduction of the nine‐item list.

Material and methods

Robson group 1 births (n = 12 763) from 2004 to 2018 were divided into four time periods; before the nine‐item list (2004‐2006), during introduction of the nine‐item list (2007‐2010), early post introduction of the nine‐item list (2011‐2014) and late post introduction of the nine‐item list (2015‐2018). The nine‐item list consists of monitoring of obstetric results, midwife coordinator, risk classification of women, three midwife‐competence levels, teamwork—the midwife, obstetrician and nurse working as a team with the common goal of a normal delivery, obstetric morning round, fetal monitoring skills and obstetric skills training. Perinatal outcomes before, during, early post and late post introduction were compared using a Student's t test for numerical variables and a Pearson chi‐squared test for categorical variables.

Results

Apgar score <7 at 5 minutes, Apgar score <4 at 5 minutes and umbilical cord arterial pH <7 did not differ significantly between the four time periods. Between before introduction and early post introduction, instrumental vaginal delivery decreased from 19.8% to 12.2% and cesarean section from 9.6% to 4.5%. The late post introduction period showed a maintained effect with 10.7% instrumental deliveries and 3.9% cesarean sections. Obstetric anal sphincter injury grade III decreased instantly during the introduction of the nine‐item list from 7.8% to 5.1% and thereafter remained unchanged.

Conclusions

Implementation of the nine‐item list increased the proportion of spontaneous vaginal deliveries by reducing the number of instrumental deliveries and cesarean sections without affecting the neonatal outcomes in nulliparous women with spontaneous onset of labor. The nine‐item list intervention seems to provide long‐term sustainable results.

Abstract [en]

Introduction

Preterm labor is a common clinical problem in obstetrics. Since the majority of women with preterm labor eventually deliver at full term, biomarkers are needed to more accurately predict who will deliver preterm. Oxylipins, given their importance in inflammation regulation, are highly interesting in this respect since labor is an inflammatory process.

Methods

Eighty women with preterm labor before 34 weeks of gestation were enrolled in a prospective observational multi-center cohort study. Oxylipin levels of 67 analytes in plasma samples were analyzed by liquid chromatography coupled to tandem mass spectrometry.

Results

Twenty-one (26%) of the women delivered before 34 weeks of gestation, and of those women, fourteen delivered within 48 h of admission. Logistic multivariate regression showed that lower levels of 9,10-DiHODE were associated with delivery before 34 weeks of gestation (aOR 0.12 (0.024–0.62)) and within 48 h ((aOR 0.13 (0.019–0.93)). Furthermore, higher levels of 11,12-DiHETrE were associated with delivery before 34 weeks of gestation ((aOR 6.19 (1.17–32.7)) and higher levels of 8-HETE were associated with delivery within 48 h ((aOR 5.01 (1.13–22.14)).

Conclusions

The oxylipin 9,10-DiHODE may be protective in preterm labor, both for delivery after 34 weeks of gestation and for delivery later than 48 h of admission, whereas 11,12-DiHETrE and 8-HETE display the opposite effect. Larger studies are needed to validate these mediators as biomarkers for prediction of preterm birth following preterm labor.
