Acute renal failure treated by slow continuous ultrafiltration. Preliminary report.

We report our initial experience with the use of slow continuous ultrafiltration in the treatment of acute renal failure. Advantages of slow continuous ultrafiltration over conventional hemodialysis are greater blood pressure stability, no need for systemic anticoagulation, augmented fluid input and removal, and enhanced ease of operation. Our results in two patients confirm other reports that this method can be successfully performed in hemodynamically unstable patients with acute renal failure.
