Three groups of "healthy' fullterm infants with hyperbilirubinaemia exposed to continuous phototherapy of different intensities, increased their oral intake of milk formula by 33%, 48% and 52% and 24, 48 and 72 h, respectively, irrespective of the intensity of exposure; this was significantly more than in the controls, who were swaddled. Serum osmolality and electrolyte values demonstrated no significant change from pre-phototherapy values, and were similar to those of the control group except for significantly raised potassium levels at 72 h in 2 of the 3 phototherapy groups. These raised values were, however, not dangerously high, and rapidly reverted to normal with cessation of phototherapy. The osmolality of the milk formula feeds was 272.4 +/- 8.2 (mean +/- SE) mmol/kg, potassium 27.8 +/- 1.4 mmol/l and sodium 16.0 +/- 0.8 mmol/l. Phototherapy even for 72 h does not significantly affect the fluid and electrolyte status of hyperbilirubinaemic infants fed with fairly high solute load milk formulas.
三组患有高胆红素血症的“健康”足月儿接受了不同强度的持续光疗，在24小时、48小时和72小时时，无论光照强度如何，其配方奶的口服摄入量分别增加了33%、48%和52%；这显著高于用襁褓包裹的对照组。血清渗透压和电解质值与光疗前的值相比无显著变化，除了3个光疗组中有2组在72小时时钾水平显著升高外，与对照组相似。然而，这些升高的值并非高到危险程度，随着光疗停止迅速恢复正常。配方奶喂养的渗透压为272.4±8.2（均值±标准误）mmol/kg，钾为27.8±1.4 mmol/L，钠为16.0±0.8 mmol/L。即使光疗72小时，对于喂养溶质负荷相当高的配方奶的高胆红素血症婴儿，其体液和电解质状态也不会受到显著影响。
