Cultured Epithelial Autografts

Le résumé fourni par la source

Eighteen patients with major burns (mean total body surface area burned was 49% and mean total body surface area with full-thickness burns was 38%) had cultured epithelial autografts applied to 2% to 35% of the body surface area. In six patients successful "take" of greater than 65% occurred, and in 12 patients less than 40% "take" occurred. Most wounds underwent early excision to subcutaneous fat or fascia, and the wounds of 16 patients had been treated previously with homograft. Cultured epithelial autografts were covered with either single or multilayered dressings. Perioperative wound cultures showed that all patients had microorganisms, and appropriate perioperative antibiotic coverage of Staphylococcus epidermidis and Pseudomonas aeruginosa was noted less frequently in the poor take group, which may have influenced subsequent cultured epithelial allograft take. Adherence and stability of cultured epithelial allografts lag behind adherence and stability of meshed split-thickness autograft. The anterior trunk and thighs are the best recipient sites. The number of autograft harvests that were required to close wounds and the length of hospital stay were not significantly decreased by the use of cultured epithelial allografts as compared with comparable full-thickness burns that were treated previously without cultured epithelial allografts. Presently, grafting with cultured epithelial allografts is an adjunct but not an alternative to conventional burn-wound coverage with split-thickness autograft, because engraftment is inconsistent.
