Some of ICU patients with Acute Renal Failure (ARF) require dialysis. Conventional or intermittent hemodialysis (HD) may cause hypotension and insufficient loss of fluids and toxins from blood. Peritoneal dialysis also my cause peritonitis and has lower efficiency than HD. We did continuous Venovenous Hemodialysis (CVVHD) for three ICU patients with ARF in Saint-Zahra Medical Center for the first time in our country. Method and Material: With a polysulfone membrane, blood pump, peritoneal dialysis solution, heparin, and a fix nurse, HD was done for 12-24 hours. Results: 1) Urea clearance was 18-50 ml/h. 2) Ultrafiltration was 160-1000 ml/h. 3) With dialysis, hemorrhage, coagulation disorder, and oxygenation recovered. 4) All of patients developed hyperglycemia and hypothermia. 5) All of patients died (two with septicemia and one with hypotension). Conclusion: In the absence of hemodialysis or peritoneal dialysis, CVVHD with present preliminary equipments is suitable and can excrete more toxins and fluids.
