Dialysis convection

WebUnfortunately, the efficiency of convection-based dialysis treatment, or hemofiltration (HF), was limited by the relatively low ultrafiltration coefficient of the dialyzers available at the time. Thus, the exchanged volume was low, and the corresponding clearance of low-molecular-weight solutes was insufficient with respect to the current ... WebAbstract. In the 1980s, conventional hemodialysis was considered as dialysis with acetate dialysate, dialysis machines without volumetric control, low blood flow and low-flux dialyzers; in the 1990s, the concept of conventional hemodialysis changed due to technological advances in dialysis machines, control of ultrafiltration and the widespread ...
