Abstract

PURPOSE: The most common cause of death in massive burn patients is burn wound sepsis. Therefore we have been using allograft skin for preventing burn wound sepsis.
METHODS
Included in this study were 71 subjects who had sustained extensive burns from December 2003 through February 2006. 1. Early selective Escharectomy was performed for full thickness burn areas. 2. Allograft skins were grafted on excision area. 3. An autograft was performed for areas with a formation of granulation tissue after the allograft skin had come away. 4. A modified sandwich grafting technique (1 : 4 ~ 6 meshed autograft with Cultured Epithelial Autografts) was performed in large sized burns. 5. Acellular dermal substitute was concurrently used to prevent burn scar contraction on joint areas.
RESULTS
Seventy one subjects were included (Fresh allograft: 9 cases, Cryo-preserved allograft: 42 cases, Glycerol preserved allograft: 20 cases). The average burn area was 41.8 (20 ~ 92) %TBSA (Total Body Surface Area). The mean area of the allograft skin used was 26.9 (8 ~ 70) %TBSA. The grafted allograft skins usually came away 3 weeks later. Four cases of initial take failure were occurred. All of these cases were pediatric patients using cadaver skin. Nine patients were dead from heart failure, severe inhalation, respiratory failure, pneumonia in old age, renal failure etc. There was no definite wound sepsis. Cultured Epithelial Autografts (CEAs) were used in fourteen cases. In twenty- five cases, acellular dermal substitute was simultaneously used.
CONCLUSION
Early selective escharectomy, allograft skin coverage, acellular dermal substitutes and wide meshed autograft with CEA application would be immensely helpful techniques in patients with extensive burns.
