title: Continuous arteriovenous hemodiafiltration in postoperative and traumatic renal failure.
abstract: Management of acute renal failure (ARF) in surgical patients has relied on supportive measures including hemodialysis and peritoneal dialysis. An alternative technique currently available is continuous arteriovenous hemodiafiltration (CAVH-D). Records of 44 surgical patients with ARF who were treated with CAVH-D in our surgical intensive care unit from 1989 to 1992 were reviewed. Thirty-five patients underwent emergency operations, and 4 patients underwent elective operations. Thirty-three patients were hemodynamically unstable immediately prior to the institution of CAVH-D, making hemodialysis a contraindication. A total of 565 CAVH-D days with an average of 13 days per patient were evaluated. Seventeen patients survived, with recovery of renal function in 13 patients. Vascular access was obtained via 227 percutaneous femoral catheters and 4 Scribner shunts. Seven vascular complications occurred, including arteriovenous fistula, pseudoaneurysm, limb ischemia, femoral artery hemorrhage, and femoral vein thrombosis. Based on these data, we conclude that CAVH-D is a safe and effective alternative in surgical patients with ARF.
