During the control period in this study, small premature infants, 1500 g in birth weight, had insensible water loss (IWL) of 2.28 g/kg/hr (equivlaent to 54 ml/kg/day), which is considerably higher than in full term infants. Under phototherapy, there was a significant increase in IWL (3.14 g/kg/hr) associated with increase of skin and rectal temperature. The heart rate and respiratory rates were comparable. Full term infants in stress situations such as phototherapy can compensate for water losses by increasing oral intake. In small premature infants, reliance must be placed upon increased amounts of parenteral fluids when under phototherapy.
在本研究的对照期,出生体重1500克的小早产儿的不显性失水量(IWL)为2.28克/千克/小时(相当于54毫升/千克/天),这明显高于足月儿。在光疗期间,IWL显著增加(3.14克/千克/小时),同时皮肤和直肠温度升高。心率和呼吸频率相当。处于光疗等应激状态下的足月儿可通过增加口服摄入量来补偿水分流失。对于小早产儿,光疗期间必须依赖增加肠外补液量。
