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.
两名无尿婴儿在慢性腹膜透析（PD）期间反复出现低钠血症。出现这种情况的原因是，在正常血清钠浓度（[Na]）下，超滤（UF）导致的钠丢失量大于婴儿配方奶粉摄入的钠量。通过增加口服钠摄入量或提高透析液[Na]浓度来纠正低钠血症。接受PD治疗的无尿婴儿出现低钠血症是因为他们超滤需求/体重较高以及市售婴儿配方奶粉钠含量较低。
