Use of cultured epidermal autografts in the treatment of large burns.
Mortality in patients with large areas of full skin thickness burns is, in part, due to complications developing during the period of prolonged delay required to obtain enough wound healing to permit skin grafting from limited donor sites. Cultured epithelial autograft (CEA) has become available as an alternative measure to the use of expanded skin autografts and regrafting. Small biopsies are taken and transported to the laboratories of BioSurface Technology where keratinocytes are grown to cover large areas during a 3-week period. The cultured keratinocytes are then available on petroleum jelly gauze which is applied to the patient. The gauze is used as a temporary dressing. To date, 37 patients have been biopsied. Grafts have been applied in 15. Graft 'take' averaged 71.5 per cent at our institution. Two of the patients grafted with CEA died of sepsis. One patient had a 100 per cent loss of the CEA grafts. In 12 patients, the use of CEA probably contributed significantly to wound coverage and survival. Such grafts are more susceptible to mechanical loss than routine autograft, although long-term coverage after several years is considered to be satisfactory. The cost of the process is high.
