Acute Renal Failure in the Elderly Treated by One‐Time Peritoneal Dialysis

To determine the factors affecting outcome of acute renal failure (ARF) in the elderly, we retrospectively studied 44 patients over the age of 65 who had undergone acute peritoneal dialysis. Thirteen patients (29%) survived 2 months or longer after dialysis treatment (“survivors”). Thirty‐one patients (71%) died within this period (“nonsurvivors”). The main factor distinguishing survivors was the frequency of sepsis (none of 13 survivors vs 17 of 31 nonsurvivors). Preexisting malignancy and total number of acute insults to renal function were signficantly less frequent, and immediate clinical and biochemical outcome of dialysis significantly better in survivors. The overall complication rate of dialysis was high (31 of 44 patients), but was significantly lower in survivors. Acute peritoneal dialysis is a useful procedure in the management of ARF in the elderly. However, we suggest that elderly patients in whom sepsis is a contributory factor to the development of ARF do not benefit from peritoneal dialysis therapy. 1988 The American Geriatrics Society
