Determinants of mortality in pediatric patients with greater than 70% full-thickness total body surface area thermal injury treated by early total excision and grafting.

Recent advancements in burn care have improved the survival rates of victims with severe burn injuries. The total mortality rate in a series of 1,057 pediatric patients admitted to Shriners Burns Institute Galveston Unit between 1982 and 1986 was 2.7%. The burn size resulting in a 50% death rate was 95% of the total body surface area (TBSA). In this study 19 survivors and 13 nonsurvivors with greater than 70% full-thickness TBSA burn injuries were compared. All survivors were adequately resuscitated upon arrival 11% sustained an inhalation injury. Forty-six per cent of the nonsurvivors sustained an inhalation injury; 31% were not initially adequately resuscitated. The presence of preadmission shock and inhalation injury were early determinants of mortality with secondary renal, pulmonary, or cardiovascular collapse being the later predictors of mortality in these massively burned pediatric patients.
