The range of thermal control and the thermoneutral range of preterm infants under 30 weeks' gestation was calculated by extrapolation of data from studies on more mature infants. Even assuming some thermoregulatory capacity, the range of control is less than 3 degrees C, the thermoneutral range is less than 0.5 degrees C, and both are greatly influenced by the rate of transepidermal water loss. Measurements of metabolic rate and effective thermal environment made on 6 infants under 30 weeks' gestation in the first week of life showed that the very preterm infant exerts little thermoregulatory control and that variations in transepidermal water loss are a major factor determining the appropriate thermal environment.
通过对更成熟婴儿研究数据的外推,计算出孕周小于30周的早产儿的体温控制范围和热中性范围。即使假设存在一定的体温调节能力,控制范围也小于3摄氏度,热中性范围小于0.5摄氏度,并且两者都受到经皮水分流失率的极大影响。对6名孕周小于30周的婴儿在出生后第一周进行的代谢率和有效热环境测量表明,极早产儿的体温调节控制能力较弱,经皮水分流失的变化是决定适宜热环境的主要因素。
