Hyponatremia in the very young chronic peritoneal dialysis patient.
Two anuric infants had recurrent hyponatremia during chronic peritoneal dialysis (PD). This occurred because at normal serum sodium concentrations ([Na]), Na losses from ultrafiltration (UF) were greater than the Na ingested from infant formula. Hyponatremia was corrected with increased oral Na intake or with increased dialysis solution [Na]. Anuric infants undergoing PD have hyponatremia because of their high UF requirements/body weight and the low Na content of proprietary infant formulas.
