Multiple efforts to achieve immediate and complete burn wound closure following early debridement have been attempted to prevent septic complications, and to decrease the morbidity and mortality associated with major burns. The BG University Hospital Bergmannsheil Bochum (BGUBB) Burn Centre admitted 157 patients with deep partial thickness and full thickness skin burns during 1991 and 1992. ⋯ A total of 57 allograft transplantations were performed on these 28 patients. Our indications for the use of glycerolized human allografts, as well as our results, are presented and discussed.

Cultured epidermal autografts (CEA) have been shown to be an effective permanent skin replacement for major burn injuries, but are more sensitive to adverse conditions than split thickness grafts (Clarke et al., 1988). Cuono et al. (1986, 1987) have described the successful use of engrafted allodermis as a wound bed for cultured grafts. We report on a method of preparing allodermis and grafting CEA in five patients with major burns (48-70 per cent TBSA, average 59.6 per cent). ⋯ Seven to 10 days after surgery, the gauze backings were removed. The average take ranged from 87-100 per cent (average 93.6 per cent). Follow-up for up to 4 years shows supple skin that has been durable, and resistant to trauma and infection.

Previous clinical observations have suggested that the application of glycerol-preserved donor skin as a temporary wound dressing provokes a weaker rejection reaction than fresh, vital donor skin. Like others, we frequently observed that considerable parts of the allodermis not only remained on the wound for an extended period of time, but even became re-epithelialized in some cases. ⋯ The immunological reaction after grafting vital DA-skin, glycerolized DA-skin onto Lewis rats, and vital as well as glycerolized Lewis-skin onto Lewis rats was compared. The results of these experiments do not support the clinical observations that the glycerolization procedure results in decreased immunogenicity of donor skin.
