In vitro Buffering Capacity of Residual Peritoneal Dialysate Fluid: Implications for Peritoneal Dialysis Therapy

Abstract

The buffering capacity of the residual peritoneal dialysate fluid from each of 5 patients undergoing continuous ambulatory peritoneal dialysis was assessed by titrating with fresh, conventional, acidic, and lactate-containing peritoneal dialysis solutions. It was found that residual fluids had considerable buffering capacity.
