Abstract
Recently, several reports have appeared on the application of Continuous Arteriovenous Hemofiltration (CAVH) for the management of severe acute renal failure. CAVH makes it possible to remove excessive sodium and water gradually without drastic change in hemodynamics. This technique is especially applicable to critically ill, perioperative renal failure patients with hemodynamic instability.
This paper reports the management of severe postoperative renal insufficiency by CAVH used in conjunction with hemodialysis. The fluid removal rate was quantitated and adjusted by a infusion pump at the ultrafiltrate end of the filter.
Three cases of severe postoperative renal failure were managed. A postoperative patient dependent on hemodialysis as well as patients with pulmonary edema and congestive heart failure markedly improved.
