Comparison of weekly urea clearances with different dialysis techniques. Although continuous therapies are less efficient than intermittent techniques, overall clearances are higher as they are utilized continuously. It is also possible to increase clearances in continuous techniques by adjustment of the ultrafiltration rate and dialysate flow rate. In contrast, as intermittent dialysis techniques are operational at maximum capability, it is difficult to enhance clearances except by increasing the size of the membrane or the duration of therapy. CAV/CVVHDF—continuous arteriovenous/venovenous hemodiafiltration; IHD—intermittent hemodialysis; CAVH—continuous arteriovenous hemodialysis; PD—peritoneal dialysis.
