Combined use of allograft and autograft epidermal cultures in therapy of burns.
Cultivation of human epidermal keratinocytes made possible the use of cultured autografts as part of the therapy of extensively burned patients. On the basis of our early results using banked cultured allografts and autografts, we developed an integral and combined burn therapy comprising banked cultured allografts for rapid healing of skin donor sites and deep partial-thickness burns, conventional split-thickness skin autografting, and when needed, cultured autografts for full-thickness burns. We compared hospital stay in 32 burn patients treated with the combined therapy and in 39 who were not treated with cultured epidermis. Three groups of patients were defined: 15 to 29 percent (n = 12), 30 to 49 percent (n = 10), and more than 49 percent (n = 10) burned body surface area. We found a 20 to 29 percent decrease in hospital stay in patients with up to 49 percent burned body surface area and a 46 percent reduction in patients suffering more extensive burns. Survival rate of extensively burned patients also was increased. We took advantage of the availability of banked cultured allografts for ambulatory treatment, without hospitalization, of pediatric patients with 5 to 20 percent burned body surface area. We show for the first time the use and benefits of this combined therapy.
