We describe a simple method of determining weight loss and hence water loss of infants in incubators. Unlike previously reported methods, it does not interfere with the microenvironment surrounding the infant. Weight loss of 16 term and 32 preterm infants was measured in both forced and natural convection. No significant increase in water loss was observed in the term infants but in the preterm infants the mean loss in natural convection was 0.85 g/kg/hour compared with 1.26 g/kg/hour in forced convection: in the most extreme situation it was doubled. This water loss represents a substantial energy loss and suggestions to minimise it are discussed.
我们描述了一种测定保温箱中婴儿体重减轻从而确定其水分流失的简单方法。与先前报道的方法不同，该方法不会干扰婴儿周围的微环境。在强制对流和自然对流两种情况下，对16名足月儿和32名早产儿的体重减轻情况进行了测量。足月儿的水分流失没有显著增加，但早产儿在自然对流中的平均流失量为0.85克/千克/小时，而在强制对流中为1.26克/千克/小时：在最极端的情况下，流失量增加了一倍。这种水分流失代表了大量的能量损失，文中还讨论了将其降至最低的建议。
