AbstractThe quantity of fluid retained during the first 48 hours of resuscitation has been suggested as an indicator of burn severity and mortality (13). In this study of 82 adult burned patients with more than 20% total body surface burns we found that the net fluid retention during the first 48 hours of resuscitation was a predictor of burn mortality and additionally 230 cc of retained fluid per kilogram of lean body mass in the initial 48 hours postburn was an excellent means for separating survivors from nonsurvivors. Fluid retention as an indicator of burn severity and mortality was compared to other methods of predicting burned patient mortality. Parameters evaluated included the per cent body surface area burned, per cent full thickness burn, presence or absence of inhalation injuries, sex, age, and ultimate outcome. The Abbreviated Burn Severity Index (ABSI) (14) was determined for each patient using these data. A comparison was made between fluid retention data, per cent body surface area burned, and the calculated Abbreviated Burn Severity Index and patient mortality. The power of each variable to predict mortality was evaluated by stepwise regression analysis. From this analysis net fluid retention during the first 48 hours of resuscitation was as accurate as the Abbreviated Burn Severity Index and was a better predictor of mortality than individual components of that Index.
