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.
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。
