Treatment of deep partial thickness burns by a single dressing of porcine acellular dermal matrix

Abstract

To explore the effect of one dressing of porcine acellular dermal matrix on deep partial thickness burns. From January 1997 to January 2004, sixty-seven cases of deep partial thickness total burned surface area (TBSA) from 50% to 90% burn wound were treated by a single dressing of porcine acellular dermal matrix (the porcine acellular dermal matrix group). Ten cases of deep partial thickness burned patients with the same TBSA treated by exposure method served as the exposure method group. The healing time of the wound was observed. The patients were followed up for 3 months to 2 years, and the scar proliferation was observed. The deep partial-thickness wound would be healed without dressing change in the porcine acellular dermal matrix group, and the average healing time was (12.2 +/- 2.6) days. The average healing time of the exposure method group was (27.4 +/- 3.5) days. Follow up of the patients within 3 months to 2 years showed that scar proliferation in the porcine acellular dermal matrix group was much less than that in the exposure method group, even no scar proliferation was observed in some patients. Without tangential excision, autografting and dressing change, a single dressing of porcine acellular dermal matrix on deep partial thickness burn wound could shorten the healing time and inhibit scar proliferation.
