To compare the efficacy of vinyl bags and thermal warming mattresses in preventing hypothermia during delivery room resuscitation and stabilization of extremely low-gestational-age neonates (ELGANs).
Preterm infants 23 to 28 weeks' gestational age were randomly allocated to either vinyl bag or thermal mattress group at delivery to prevent hypothermia. The primary outcome of the study was the axillary temperature on admission to the neonatal intensive care unit.
A total of 41 infants were enrolled in the study. The mean admission temperature in the vinyl bag group was 36.1°C ± 0.7°C as compared with 35.8°C ± 1.3°C in the thermal mattress group. The subgroup of these infants with lower birth weight (<750 g) had significantly higher admission temperature with vinyl bags (36°C ± 0.4°C) compared with thermal mattress (35°C ± 1.3°C).
Vinyl bags and warming mattress are equally effective in improving admission temperature in ELGANs. Improvements in other areas such as delivery room temperature may be needed to achieve the goal of preventing hypothermia in this vulnerable population.
比较乙烯袋和热保温床垫在预防产房复苏和稳定极低出生体重儿（ELGANs）期间低体温的疗效。
将 23 至 28 周胎龄的早产儿在分娩时随机分配到乙烯袋或热床垫组，以预防低体温。本研究的主要结局是新生儿重症监护病房入院时的腋温。
共有 41 名婴儿入组本研究。乙烯袋组的平均入院温度为 36.1°C ± 0.7°C，而热床垫组为 35.8°C ± 1.3°C。对于出生体重较低（<750 g）的婴儿亚组，乙烯袋的入院温度明显较高（36°C ± 0.4°C），而热床垫组为 35°C ± 1.3°C。
乙烯袋和加热床垫在改善 ELGANs 的入院温度方面同样有效。可能需要改善分娩室温度等其他方面，以实现预防这一脆弱人群低体温的目标。
