生后72小时内新生儿体温调查

The Investigation of Neonatal Body Temperature in the First 72 Hours After Birth

目的探讨新生儿生后72小时内的体温调节情况,证实 WHO 暖链的重要性。方法1995年春、夏、冬三季在本院分娩的新生儿302例于生后脐带处理完毕,回休养室即刻,1,2,4,6,8,10,12,14,16,18,20,22,24,48及72小时测腋下体温,共17次,观察各时间段体温的变化。结果平均体温达到36.5℃的时间为春季生后10小时,夏、冬季生后14小时。夏季生后2小时低体温率达95%以上,冬季生后6小时仍有97.2%低体温新生儿。随生后时龄增加,低体温率逐渐下降。但生后72小时,春夏冬三季低体温率仍分别高达16.0%,34.1%,27.7%。结论降低新生儿寒冷损伤不仅是农村医院,而且也是大城市医院的重要任务,关键是医护人员对低体温新生儿的影响要有足够的认识。

Objective To comfirm the importance of WHO'warm chain' by investigating neonatal body temperature after birth.Methods Axillary temperatures of 302 neonates born in our hospital in spring,summer and winter of 1995 were monitored immediately after cord ceased and 1,2,4,6,8,10,12,14,16,18,20,22,24,48,and 72 hours after birth.The incidence of low body tem- perature in each time was calculated.Resultes The time after birth that average body temperature need to reach 36.5℃ was ten hours in spring,14 hours in summer and winter.The incidence of low body temperature at 2 hours after birth in summer was 95 %,at 6 hours in winter was 97%.The in- cidence of low body temperature at 72 hours were still 16% in spring,34.1% in summer and 27.7% in winter respectively.Conclusion Key point in carrying out'warm chain'is to enhance the re- sponsibility of medical staff not only in rural hospitals,but also in urban hospitals.
