CONTINUOUS ARTERIOVENOUS HEMOFILTRATION THERAPY FOR ACUTE RENAL FAILURE FOLLOWING AORTIC RECONSTRUCTION

Abstract

Continuous arteriovenous hemofiltration (CAVH) was performed in seven patients with acute renal failure following aortic reconstruction. Hemofilter was PAN-5OP. Blood access was obtained with 14G catheter from femoral artery. Ultrafiltration was obtained by the arterial blood pressure. Heparin was administered as anticoagulation therapy. Hemofilter was exchanged when ultrafiltration rate was getting less than 200 mililiter per hour. The average period of hemofilter exchange was 41.6 hours and the average rate of ultrafiltration was 791 mililiter per hour. Systolic arterial blood pressure and ultrafiltraion rate had a positive correlative tendency. Three cases were weaned from CAVH, two cases died within two days after the begining of CAVH and another two cases were well controlled for long period concerning acid-base, electrolyte and body fluid valance. In three of four unsuccessful cases retroperitoneal hematoma which had existed before operation increased. We need further examination about the anticoagulation therapy but CAVH was effective for acute renal failure following aortic reconstruction.
