我们测量了207名平均出生年龄为12.7±10.6周的婴儿的经皮水分蒸发率（ER）。在标准条件下进行多测睡眠记录时，使用蒸发仪从前额进行测量。ER值以g/m2 X h计算。与安静清醒（11.6 +/- 7.4）或非快速眼动（NREM）睡眠（11.2 +/- 7.6）期间测量的值相比，快速眼动（REM）睡眠期间的蒸发速率（8.5 +/- 4.4 g/m2 X h）显著降低。协方差分析显示，这些差异与年龄、性别、体重或直肠温度无关。这些记录在正常婴儿身上的数据表明，在比较水分蒸发研究的结果时，需要考虑受试者的睡眠或清醒状态。
Transepidermal water evaporation rate (ER) was measured in 207 infants with a mean postnatal age of 12.7 +/- 10.6 weeks. Measurements were made from the forehead with the use of an Evaporimeter during polygraphic sleep recordings performed under standard conditions. ER values were computed in g/m2 X h. Evaporation rates were significantly lower during rapid eye movement (REM) sleep (8.5 +/- 4.4 g/m2 X h), compared to values measured during quiet wakefulness (11.6 +/- 7.4) or non-REM (NREM) sleep (11.2 +/- 7.6). The differences were not related to age, sex, weight, or rectal temperature, as shown by a covariance analysis. These data, recorded in normal infants, indicate the need to consider the state of sleep or wakefulness of the subjects when comparing results of water evaporation studies.
