Continuous arteriovenous hemofiltration in the treatment of 100 critically ill patients with acute renal failure: report on clinical outcome and nutritional aspects.
The clinical outcome for 100 consecutive patients with multiorgan failure including acute renal failure (ARF) was studied. Fifty-eight of the patients had acute renal failure due to complications during and after major surgery. Seventy-three of the patients had a urine output of less than 400 ml/24 hours. The majority of the patients also had complications such as septicemia or respiratory insufficiency and required vasopressor infusions. All patients were treated with continuous arteriovenous hemofiltration (CAVH). The duration of the CAVH treatment varied between a few hours and 90 days, with a mean of 8 days. The mean ultrafiltration volume per 24 hours was, on the average, 12 liters. CAVH resulted in adequate uremic control in 89 cases, but additional treatment with intermittent hemofiltration was necessary in 11 patients. The total survival rate was 45% including survival rates as high as 54% in patients with ARF complicating abdominal aortic surgery. Only three patients were referred for chronic dialysis therapy. In a subgroup of 17 patients with ARF complicating abdominal aortic surgery the nutritional aspects during CAVH were studied. It is concluded that during CAVH therapy it is possible to give adequate nutritional support even to hypercatabolic and anuric patients.
