The present study compares some of the metabolic effects of hemodialysis of fasting patients with and without glucose in the dialysate bath. Unlike glucose dialysis, glucose-free dialysis caused marked decreases in blood levels of glucose, insulin, lactate, and pyruvate along with profound increases in acetoacetate and beta-hydroxybutyrate. It is concluded that oxidation of fatty acids increases to meet energy demands and that the combined processes of glycogenolysis and gluconeogenesis serve to prevent critical hypoglycemia during glucose-free dialysis.
