The responses of newborn babies to overheating were investigated by exposing them to progressively higher incubator air temperatures until either sweating occurred or the rectal temperature reached 37.9 degrees C. 112 studies were performed on 83 healthy term and preterm infants. Activity, posture, heart rate, respiratory rate, skin colour and abdominal skin and hand temperature were monitored. Most babies regardless of gestational age became less active, and they frequently fell asleep at the warmest setting. The majority of infants altered their posture from predominantly flexion to extension. There were no significant changes in heart rate or respiratory rate. The skin of almost all the babies became redder, and the difference between central and peripheral skin temperatures decreased with warming. The pattern of these changes varied with maturity suggesting the development of vasomotor control. It is a surprising finding that even the most immature babies appear to make appropriate responses to heat stress. These responses may aid in the recognition of a baby who is too warm.
通过将新生儿置于逐渐升高的培养箱空气温度中，直至出汗或直肠温度达到37.9摄氏度，来研究新生儿对过热的反应。对83名健康足月儿和早产儿进行了112项研究。监测了活动、姿势、心率、呼吸频率、皮肤颜色以及腹部皮肤和手部温度。大多数婴儿，无论其胎龄如何，活动都减少了，并且在最温暖的环境中经常入睡。大多数婴儿的姿势从主要的屈曲变为伸展。心率和呼吸频率没有显著变化。几乎所有婴儿的皮肤都变得更红，随着温度升高，中心皮肤温度与外周皮肤温度之间的差异减小。这些变化模式随成熟度而变化，表明血管运动控制的发展。一个令人惊讶的发现是，即使是最不成熟的婴儿似乎也能对热应激做出适当反应。这些反应可能有助于识别过热的婴儿。
