OBJECTIVETo seek ideal strategies in saving a patient with very extensive deep burns, and measures for functional reconstruction after convalescence.

METHODSA patient with 99. 5% TBSA flame burn injury (III degrees 80%, deep second degree 14.5% and superficial II degrees 5%), complicated with hypernatremia and hyperchloraemia was admitted 76 hours after the injury. Early escharectomy and alloskin grafting were performed. Because of the lack of autoskin donor site, the skin grafting of autologous skin was only undertaken whenever there was an available source, and the remaining wounds were temporarily covered with allografts. Finally the patient survived. After healing of all the wounds, contractures were corrected with skin from scars, flaps of scarred skin or composite skin, and more than 30 cicatricial contracture deformities were corrected after convalescence.

RESULTSAfter initial treatments and extensive early escharectomy, the patient's condition became stable gradually, without adverse complications. After 7 operations, the wounds finally healed completely after 106 days. The function of all joints were restored well and external appearance improved after 15 plastic and reconstructive operations during convalescence period. The patient was fully rehabilitated and resumed his original work 26 months after the injury.

CONCLUSIONFor those patients with massive burns and short of donor site, alloskin grafting after early escharectomy, and persistent repeated microskin grafting whenever any small amounts of own skin is available, is essential to stabilize the patients' condition, and reduce complications. Covering the wounds as the result of shedding off of eschar with alloskin can protect the undamaged cells in skin appendages to promote re-epithelization and wound healing. It is feasible to harvest skin grafts from scars, and use scar skin flaps and composite skin to repair contractures after convalescence with good outcome in function and external appearance.
