Abstract：
OBJECTIVE: Body temperature for a known ambient temperature is not known for infants born at term. We aimed to determine the normal range and the incidences of hypothermia and hyperthermia during the first 24 hours of life in healthy term-born infants nursed according to WHO recommendations.
METHODS: Prospective observational study.
METHODS: Norwegian single centre district hospital. Infants were observed during skin-to-skin care or when dressed in cots.
METHODS: Convenience sample of 951 healthy infants born at term.
METHODS: Delivery room temperature was aimed at 26-30°C and rooming-in temperature at 24°C. We measured rectal and room temperatures at 2, 4, 8, 16 and 24 hours of age.
METHODS: Percentile curves for rectal temperature. Proportions and risk factors for hypothermia and hyperthermia.
RESULTS: The mean (SD) room temperature was 24.0°C (1.1), 23.8°C (1.0), 23.8°C (1.0)., 23.7°C (0.9) and 23.8°C (0.9). The median (2.5, 97.5 percentile) rectal temperature was 36.9°C (35.7-37.9), 36.8°C (35.9-37.5), 36.9°C (36.1-37.5), 37.0°C (36.4-37.7) and 37.1°C (36.5-37.7). Hypothermia (<36.5°C) occurred in 28% of the infants, 82% of incidents during the first 8 hours. Risk factors for hypothermia were low birth weight (OR 3.1 (95% CI, 2.0 to 4.6), per kg), male sex, being born at night and nursed in a cot versus skin to skin. Hyperthermia (>37.5°C) occurred in 12% and most commonly in large infants after 8 hours of life. Risk factors for hyperthermia were high birth weight (OR 2.2 (95% CI, 1.4 to 3.5), per kg), being awake, nursed skin to skin and being born through heavily stained amniotic fluid.
CONCLUSIONS: Term-born infants were at risk of hypothermia during the first hours after birth even when nursed in an assumed adequate thermal environment and at risk of hyperthermia after 8 hours of age.

摘要：
目的：足月出生的婴儿不知道已知环境温度的体温。我们旨在确定健康足月出生婴儿在生命的头24小时内的正常范围以及低温和高温的发生率根据WHO的建议进行护理。
方法：前瞻性观察性研究。
方法：挪威单中心地区医院。在皮肤对皮肤护理或穿着婴儿床时观察到婴儿。
方法：足月出生的951名健康婴儿的便利样本。
方法：分娩室温度为26-30°C，房间温度为24°C。我们测量了2、4、8、16和24小时的直肠和室温。
方法：直肠温度的百分位曲线。低体温和高热的比例和危险因素。
结果：室温的平均值（SD）为24.0°C（1.1），23.8°C(1.0),23.8°C(1.0)。,23.7°C（0.9）和23.8°C（0.9）。直肠温度中位数（2.5，97.5百分位数）为36.9°C（35.7-37.9），36.8°C(35.9-37.5),36.9°C(36.1-37.5),37.0°C（36.4-37.7）和37.1°C（36.5-37.7）。28％的婴儿发生低温（<36.5°C），82%的事故发生在前8小时。低体温的危险因素是低出生体重（OR3.1（95％CI，2.0至4.6），每公斤），男性,晚上出生，在婴儿床里护理，而不是皮肤对皮肤。热疗（>37.5°C）发生在12％，最常见于8小时后的大婴儿。高热的危险因素是高出生体重（OR2.2（95％CI，1.4至3.5），每公斤），醒着,护理皮肤到皮肤，并通过严重染色的羊水出生。
结论：足月出生的婴儿在出生后的头几个小时内，即使在假定的适当热环境中进行护理，也有体温过低的风险，并且在8小时后有体温过高的风险。
