Twenty-four-hour metabolic balance studies were performed in ten jaundiced preterm infants, five light-treated (phototherapy) and five controls. Each of the light-treated infants was studied twice, once during phototherapy (period I) and once 48 hours after phototherapy (period II). Control infants were similarly studied during the corresponding days. Compared to period II and control infants, during period I the light-treated infants had less weight gain. Intestinal transit time was decreased by 50%. Fecal excretion of nitrogen, sodium, and potassium was increased. Stool water loss was increased twofold to threefold with a decrease in water balance. Unmeasured water loss was increased. These studies underscore the need for careful attention to fluid and caloric supplementation during phototherapy.
对10名黄疸早产儿进行了24小时代谢平衡研究，其中5名接受光照治疗（光疗），5名作为对照。每名接受光疗的婴儿均进行了两次研究，一次在光疗期间（第一阶段），一次在光疗后48小时（第二阶段）。对照婴儿在相应的日子里也进行了类似的研究。与第二阶段和对照婴儿相比，在第一阶段，接受光疗的婴儿体重增加较少。肠道转运时间减少了50%。氮、钠和钾的粪便排泄增加。粪便水分流失增加了两倍至三倍，水平衡下降。未测定的水分流失增加。这些研究强调了在光疗期间需要密切关注液体和热量补充。
