EFFECT OF AN ACIDIC PYRUVATE-BASED PERITONEAL-DIALYSIS SOLUTION ON THE PH OF A RESIDUAL PERITONEAL DIALYSATE FLUID

An acidic (pH 5.2) pyruvate-based peritoneal dialysis solution or an e qually acidic lactate-based counterpart was added to a residual fluid (i.e., peritoneal effluent) obtained from each of 6 continuous ambulat ory peritoneal dialysis patients. It was found that the residual fluid s were able to raise the pH of the resultant residual fluid/peritoneal dialysis solution mixture to a higher level in the case of the pyruva te-based solution than in the case of the lactate-based one.
