硬膜外麻醉联合无保护会阴接生降低会阴切开率的临床观察

Clinical observation of epidural anesthesia combined with unprotected perineum delivery in reducing episiotomy rate

目的探讨硬膜外麻醉联合无保护会阴接生在降低会阴切开率方面的作用。方法选取2016-04~2017-12于该院正常分娩的产妇80例为实验组,接受硬膜外麻醉联合无保护会阴接生。同时选取同期在该院正常分娩产妇80例为对照组,接受传统阻滞麻醉下的保护会阴接生。对比分析两组产妇的第二产程时间、会阴侧切率和会阴裂伤程度。结果实验组产妇的第二产程时间为(31.6±5.4)min,明显短于对照组产妇(P<0.05)。实验组产妇的会阴侧切率和会阴Ⅱ度损伤率明显低于对照组产妇,会阴完整率明显高于对照组产妇,差异有统计学意义(P<0.05)。结论与传统的分娩模式相比,硬膜外麻醉联合无保护会阴接生技术能明显地缩短产程,降低会阴侧切率和减少会阴裂伤程度,促进产后恢复,值得推广应用。

Objective To investigate the effect of epidural anesthesia combined with unprotected perineum delivery on reducing episiotomy rate.Methods 80 cases of pregnant women who gave normal birth in our hospital from April 2016 to December 2017 were selected as the experimental group,and the experimental group received epidural anesthesia combined with unprotected perineum delivery.80 cases of pregnant women who gave normal birth in our hospital in the same period were selected as the control group.The control group received traditional block anesthesia.The second stage of labor time,maternal perineal resection rate and perineal laceration were compared between the two groups.Results The second stage of labor time in the experimental group(31.6±5.4)min was significantly shorter than that in the control group(P<0.05).The maternal perineal resection rate and perineumⅡinjury rate in the experimental group were significantly lower than those in the control group.The integrity rate of the experimental group was significantly higher than that of the control group(P<0.05).Conclusion Compared with the traditional delivery mode,epidural anesthesia combined with unprotected perineum delivery technique can significantly shorten the labor process,reduce the episiotomy rate and perineal laceration degree,and promote postpartum recovery.
