Increased survival after major thermal injury. A nine year review

This study has reviewed the results of burn care in a burn center between 1978 and 1986. The total population included 1,458 patients. Mean burn size was 19 percent total body surface area, mean patient age was 24.4 years, and overall survival rate was 92 percent. We separately analyzed patients with burns of 30 percent total body surface area or greater during both halves of the study with respect to survival and length of hospital stay. Before 1982, patient survival was 59 percent and mean length of hospital stay was 28.1 days. Since that, the survival rate increased to 77 percent and mean length of hospital stay increased to 35.2 days. The early burn mortality rate remained nearly constant during the period of study (17 percent during the first half of the study and 16 percent during the second half), but the late mortality rate decreased significantly during the second half of the study (24 percent versus 8 percent, p less than 0.01). These data demonstrate increased survival rates after major thermal injury due to improvements in prevention and treatment of sepsis and other late complications of thermal injury.
