AbstractBackground. The use of skin substitutes as temporary or permanent coverings has been a subject of research and study since 1500 BC. Temporary coverage of the burn wound can decrease the metabolic rate, fluid loss, pain, and colonization. The aim of this study is to review clinical experience with Biobrane and aldehyde-treated porcine skin (E.Z. Derm) as biosynthetic skin substitutes for the treatment of excised burn wounds. Methods. Fifty-two patients (42 males and 10 females) with deep dermal and full-thickness burns were selected for this retrospective study. Half of these patients were treated with Biobrane (this part of the study covered the period Jan. 1995/Dec. 1999) and the other half were treated with E.Z. Derm (Jan. 2000/Dec. 2005). The mean total body surface area (TBSA) burned was 30%. The excisional therapy was carried out in stages, each procedure being limited to 7-15% TBSA. All the patients underwent either tangential excision or excision down to the muscle fascia. The male/female ratio was 3:1 and the patients' ages ranged between 5 and 67 yr (mean, 35 yr). Data collection included: initial observation (age, sex extent of burn, depth of burn, photograph), skin substitute observation (adherence, presence of fluid collection, rejection, infection, photograph), and follow-up wound evaluation. Results. Both Biobrane and E.Z. Derm reduced pain, decreased evaporative water and heat loss, and limited bacterial growth. Both decreased exudative protein loss, protected the underlying vessels and nerves, and enhanced the healing of partial-thickness wounds. Both promoted the development of granulation tissues to be ready for autografting, and neither presented antigenicity or transmitted diseases. Porcine skin showed limited wound adhesion and limited control of infection compared to Biobrane. Conclusion. Biobrane and E.Z. Derm protected excised burn wounds from bacterial contamination and dehydration. It can be concluded that Biobrane has the potential for long-term adherence (10 days). Aldehyde-treated porcine skin (E.Z. Derm) is a reliable tool for short-term use and should not remain on the wound more than 3-4 days.
