To evaluate in preterm infants whether polyethylene caps prevent heat loss after delivery better than polyethylene occlusive wrapping and conventional drying.
This was a prospective, randomized, controlled trial of infants <29 weeks' gestation including 3 study groups: (1) experimental group in which the heads of patients were covered with a polyethylene cap; (2) polyethylene occlusive skin wrap group; and (3) control group in which infants were dried. Axillary temperatures were compared at the time of admission to the neonatal intensive care unit (NICU) immediately after cap and wrap removal and 1 hour later.
The 96 infants randomly assigned (32 covered with caps, 32 wrapped, 32 control) completed the study. Mean axillary temperature on NICU admission was similar in the cap group (36.1 degrees C +/- 0.8 degrees C) and wrap group (35.8 degrees C +/- 0.9 degrees C), and temperatures on admission to the NICU were significantly higher than in the control group (35.3 degrees C +/- 0.8 degrees C; P < .01). Infants covered with polyethylene caps (43%) and placed in polyethylene bags (62%) were less likely to have a temperature <36.4 degrees C on admission to the NICU than control infants (90%). In the cap group, temperature 1 hour after admission was significantly higher than in the control group.
For very preterm infants, polyethylene caps are comparable with polyethylene occlusive skin wrapping to prevent heat loss after delivery. Both these methods are more effective than conventional treatment.
评估在早产儿中，聚乙烯帽是否比聚乙烯密闭包裹和常规干燥更能防止分娩后热量散失。
这是一项针对<29 周龄婴儿的前瞻性、随机、对照试验，包括 3 个研究组：（1）实验组，患者头部覆盖聚乙烯帽；（2）聚乙烯密闭皮肤包裹组；（3）对照组，婴儿干燥。在新生儿重症监护病房（NICU）入院时、帽和包裹去除后立即以及 1 小时后比较腋温。
96 名随机分配的婴儿（32 名覆盖帽子，32 名包裹，32 名对照组）完成了研究。帽组（36.1°C ± 0.8°C）和包裹组（35.8°C ± 0.9°C）NICU 入院时的平均腋温相似，NICU 入院时的体温明显高于对照组（35.3°C ± 0.8°C；P<.01）。用聚乙烯帽覆盖的婴儿（43%）和放在聚乙烯袋中的婴儿（62%）在 NICU 入院时体温<36.4°C 的比例低于对照组（90%）。在帽组中，入院 1 小时后的体温明显高于对照组。
对于极早产儿，聚乙烯帽与聚乙烯密闭包裹一样能防止分娩后热量散失。这两种方法都比常规治疗更有效。
