Increased survival after massive thermal injuries in adults

Abstract

Survival of major burn injuries has improved markedly from an expected survival of 10% to 20% in both children and adults to an expected survival of 60% in children with burns greater than 70% BSA. Increased survival for adults after similar burn injuries has been less dramatic than in children because of the profound influences of advancing age and the coexistent processes of aging upon survival after a major injury. Consecutive admissions of patients with massive burn injuries (greater than or equal to 70% BSA) to the Massachusetts General Hospital Adult Burn Unit from 1974 to 1986 were analyzed statistically using univariate and multiple logistic regression analysis to identify factors associated with survival and to identify patient characteristics associated with increases in expected survival. Survival of adults with massive burn injuries has improved markedly, from 24% of adults admitted to the Adult Burn Center in 1974-75 to 48% of adults admitted in 1984-86. An increased likelihood of survival was shown to be associated with the use of artificial skin. Improved survival rates in these massive burn injuries were attributed to multiple factors including wound management of prompt eschar excision and immediate wound closure.
