为探讨低体温儿与产科因素的关系，对我院６７３ 例新生儿采用腋温测定法，观察产后体温下降程度及恢复正常所需要的时间，有产科因素的新生儿体温小于３６ ℃占７４－９２％ ，生后４８ 小时仍未恢复者占８２－２９％ ，早产儿、低体重儿生后体温均小于３５ ℃；剖宫产儿体温≤３５ ℃占６６－１１％ ，与阴道分娩儿比较差异显著（ Ｐ＜ ０－０１）；有胎儿窘迫和新生儿窒息者与无此因素相比较，低体温发生程度差异显著（ Ｐ＜０－０１）。纠正产科因素是降低低体温儿发生率的重要环节。
In order to explore the relationship between hypothermia and obstetric factors, the 673 newborns in our hospital axillary temperature measurement method to observe the degree of postpartum body temperature decreased and the time required to return to normal, obstetric neonatal body temperature is less than 36 ℃ accounted for 74- 92%, 48 hours after birth still not recovered accounted for 82-29%, premature children, low birth weight body weight after birth were less than 35 ℃; cesarean section body temperature ≤ 35 ℃ accounted for 66-11%, compared with vaginal delivery (P <0-01). Compared with those without fetal distress and neonatal asphyxia, the incidence of hypothermia was significantly different (P <0-01). Correcting obstetric factors is an important part of reducing the incidence of hypothermia.
