Effect of the Direction of Dialysate Flow on the Efficiency of Continuous Arteriovenous Haemodialysis

Abstract

We have investigated the effect of the direction of the dialysate flow during continuous arteriovenous haemodialysis. Under similar conditions countercurrent flow was more efficient than concurrent flow in terms of both urea clearance, (mean ± SEM), 23.5 ± 0.5 compared to 18.4 ± 0.4 ml/min (p
