Abstract [en]

The impression among the attending physicians at their Burn Centre is that the number of contact burns caused by glass-fronted stoves is increasing, particularly in the youngest group of patients. It is an interesting subgroup, as these injuries are preventable. The authors’ aim of this study was to find out whether the incidence of burns after contact with glass-fronted stoves has increased.

The authors included all patients aged between 0 and 3.9 years who presented to the National Burn Centre during the period 2008–2015 with contact burn injuries caused by glass-fronted stoves. The change in incidence over time was calculated from national records and analyzed with simple linear regression.

Fifty-six patients were included, of whom 20 were treated during the past 2 years of the study. Thirty-seven of the 56 were boys (66%), median (10–90 percentiles) age was 1.1 (0.7–2.5) years, percentage total body surface area burned was 0.6% (0.1–2.0), 12 were admitted for overnight stay in hospital, and seven needed operations. The incidence was 0.34/100 000 children-years during the first 2 years, and it was three times as high during the past 2 years. The increase in incidence was 0.24/100 000 children-years by each 2-year period (P = .02).

The authors’ results indicate that contact burns among children caused by glass-fronted stoves are increasing in Sweden. The authors propose that there should be a plan for their prevention put in place.

Abstract [en]

Background Laser Speckle Contrast Imaging (LSCI) is a non-invasive and fast technique for measuring microvascular blood flow that recently has found clinical use for burn assessment and evaluation of flaps. Tissue motion caused by for example breathing or patient movements may however affect the measurements in these clinical applications, as may distance between the camera and the skin and tissue curvature. Therefore, the aims of this study were to investigate the effect of frame rate, number of frames/image, movement of the tissue, measuring distance and tissue curvature on the measured perfusion. Methods Methyl nicotinate-induced vasodilation in the forearm skin was measured using LSCI during controlled motion at different speeds, using different combinations of frame rate and number of frames/image, and at varying camera angles and distances. Experiments were made on healthy volunteers and on a cloth soaked in a colloidal suspension of polystyrene microspheres. Results Measured perfusion increased with tissue motion speed. The relation was independent of the absolute perfusion in the skin and of frame rate and number of frames/image. The measured perfusion decreased with increasing angles (16% at 60, p = 0.01). Measured perfusion did not vary significantly between measurement distances from 15 to 40 cm (p = 0.77, %CV 0.9%). Conclusion Tissue motion increases and measurement angles beyond 45 decrease the measured perfusion in LSCI. These findings have to be taken into account when LSCI is used to assess moving or curved tissue surfaces, which is common in clinical applications.

Abstract [en]

Background: Venous congestion in skin flaps is difficult to detect. This study evaluated the ability of tissue viability imaging (TiVi) to measure changes in the concentration of red blood cells (CRBC), oxygenation, and heterogeneity during vascular provocations in a porcine fasciocutaneous flap model.

Methods: In 5 pigs, cranial gluteal artery perforator flaps were raised (8 flaps in 5 pigs). The arterial and venous blood flow was monitored with ultrasonic flow probes. CRBC, tissue oxygenation, and heterogeneity in the skin were monitored with TiVi during baseline, 50% and 100% venous occlusion, recovery, 100% arterial occlusion and final recovery, thereby simulating venous and arterial occlusion of a free fasciocutaneous flap. A laser Doppler probe was used as a reference for microvascular perfusion in the flap.

Results: During partial and complete venous occlusion, increases in CRBC were seen in different regions of the flap. They were more pronounced in the distal part. During complete arterial occlusion, CRBC decreased in all but the most distal parts of the flap. There were also increases in tissue oxygenation and heterogeneity during venous occlusion.

Conclusions: TiVi measures regional changes in CRBC in the skin of the flap during arterial and venous occlusion, as well as an increase in oxygenated hemoglobin during venous occlusion that may be the result of reduced metabolism and impaired delivery of oxygen to the tissue. TiVi may provide a promising method for measuring flap viability because it is hand-held, easy to-use, and provides spatial information on venous congestion.
