椎管内分娩镇痛对产妇体温影响的机制研究

Study of influencing mechanism on spinal labor analgesia for maternal body temperature

目的探讨椎管内镇痛后对产妇体温的影响机制。方法临床随机选定样本120例,分为实验组和对照组各60例。实验组产妇行椎管内分娩镇痛,对照组不采取任何镇痛措施,观察比较两组产妇体温、心率、血压等指标的变化。结果实验组体温在麻醉后5 min、30 min、2 h与麻醉前比较均无显著性差异(P>0.05);实验组产妇麻醉后5 min、30 min、2 h内体温显著低于对照组(P<0.05)。结论采用椎管内分娩孕妇体温变化幅度较低,有效控制产妇基础代谢,建议产妇分娩时采用椎管内的镇痛处理。

Objective To study the influencing mechanism of spinal labor analgesia for maternal body temperature. Methods The 120 cases were randomly divided into experimental group and control group, 60 cases in each group. The puerperas in experimental group were treated with spinal labor analgesia, while the puerperas in control group were not treated with any analgesics, the maternal body temperature, heart rate, blood pressure and other indicators were compared between the two groups. Results Compared with before anesthesia, the maternal body temperature of experimental group in 5 min, 30 min, 2 h after anesthesia were not significant different （P 〉 0.05）; and the maternal body temperature of experimental group in 5 min, 30 min, 2 h after anesthesia were significantly lower than control group （P 〈 0.05）. Conclusion The range of maternal body temperature by using spinal labor analgesia is steady, and it can effectively control the basic metabolism, so we suggest using spinal labor analgesia for maternal delivery.
