Summary Slow continuous therapies are the choice treatment in critically ill patients with acute renal failure (ARF). Over 4 years (1994‐97) we retrospectively studied 84 intensive‐care unit patients suffering from ARF and multiple organ failure, and treated with continuous venonenous haemodialysis (CVV‐HD). The main cause of ARF was sepsis (59.3%). The global mortality was 88% and the patients who died were older than the survivors (p = 0.004). The main cause of dialyser change was the ratio FUN/BUN ≤ 0.8 (61.6%); this ratio was calculated from the quotient filtrate urea nitrogen / blood urea nitrogen (urea nitrogen = urea / 2.14). Most patients (94.8%) treated with initial replacement fluid infusion didn't show falls in blood pressure (BP). Conclusions : 1. The mortality was higher in elderly patients. 2. In most cases the monitoring FUN/BUN ratio allowed recovery of the patient's blood before clotting in the extracorporeal circuit. 3. The replacement fluid infusion at the beginning of the CVV‐HD procedure contributes to patient's haemodynamic stability, because BP usually falls due to excessive ultrafiltration.
