Abstract

The effect of bicarbonate dialysate (BD) on acid-base status in six pediatric CAVHD patients was examined during seven episodes of metabolic acidosis. When metabolic acidosis was not corrected with CAVHD, a sterile BD was substituted for either acetate- or lactate-based dialysate. Pre- and post-BD substitution levels of lactate, HCO3, PCO2, anion gap, and pH were recorded, as well as dose of intravenous (i.v.) bicarbonate. Improvements in pH and serum HCO3 were seen in all seven cases. Anion gap decreased in all but one of the patients who were switched from lactate to bicarbonate dialysate, with improvement most marked in those patients with marked elevation of the anion gap. No adverse effect on PCO2 was noted. Lactate dialysate may be less effective when serum lactate levels are high, and may contribute to further elevation of lactate levels and anion gap. These data suggest that bicarbonate dialysate may be preferable to lactate or acetate dialysate in CAVHD patients with persistent metabolic acidosis.
