Acute renal failure (ARF) is a rare, but serious, complication after burn injury that is commonly thought to be fatal. Before the modern era, there were few survivors of burn injuries who required dialysis. We report our 10-year experience with ARF and dialysis at the Los Angeles County + USC burn unit. During the period of August 1994 to February 2004, 3356 patients were admitted. Furthermore, 1143 patients were admitted to the intensive care unit and 1125 had burns >10% TBSA. Thirty-three patients developed ARF necessitating dialysis, equaling 0.98% of all admitted patients, and 2.7% of patients with TBSA >10% burns, which is at the low end of published burn unit data. The average age of these patients requiring dialysis was 49 years, 91% were men, 24% were diabetic, and 39% were positive for substances of abuse at admission, and the average TBSA burned was 36%. This is compared with an average age of 31 years, 70% men, 7.3% diabetic, and 14.7% intoxicated in the general burned population at our burn unit. Furthermore, our overall mortality in the burn unit was 5% overall and 14% in patients with >10% TBSA burns during the study period. In patients requiring hemodialysis, the mortality rate was 69.7%. The average time to hemodialysis was 14 days in our series, and patients, on average, required 10.3 days of dialysis support. These mortality data are the lowest recorded for burned patients requiring dialysis and suggest that ARF is a survivable complication in some of these patients.
