Toxic epidermal necrolysis: use of Biobrane or skin coverage reduces pain, improves mobilisation and decreases infection in elderly patients.

Abstract

Toxic epidermal necrolysis is a rare disease with high mortality due to generalised infection, sepsis or lung involvement, and requires discontinuation of all potentially triggering medications and intensive care in a specialised burn centre. Apart from wound care with antiseptics, wound coverage may be achieved with a skin substitute; treatments are compared with regard to infection, protein loss, re-epithelialisation and mortality. Of 14 people with toxic epidermal necrolysis affecting >30% body surface area, eight received daily dressing changes using Lavasept nd six received wound coverage with Biobrane. Demographic data, SCORTEN score, mortality, visual-analog pain scale, mobilisation, time to re-epithelialisation, serum protein, albumin, C-reactive protein and leukocytes, and body temperature were evaluated in all cases. Mean age of patients was 68.0+/-14.8 years, mean body surface area affected was 66.4%, median SCORTEN score was three and overall mortality was 36%. In the Biobrane ompared with the Lavasept control) group, mean pain was significantly reduced (2.9 versus 5.5 on the scale, p<0.05), mobilisation was significantly earlier (walking at 3 days versus 7 days, p=0.003), re-epithelialisation was complete in 12.5 days versus 16 days, and at 9 days there was reduced decrease of serum proteins and significantly lower levels of C-reactive protein and white cells (p<0.05). Early wound coverage with synthetic skin substitute such as Biobrane s beneficial compared with conservative antiseptic wound treatment, but mortality rate is not significantly different.
