目的探讨硬膜外阻滞麻醉用于无痛分娩的临床效果。方法选取2014年1月至2016年1月辽宁省开原市妇幼保健院收治的178例足月、初产、单胎、头位、无产科合并症、无麻醉禁忌证的孕产妇为研究对象,根据自愿原则,将要求无痛分娩的86例孕产妇作为观察组,其余选择自然分娩的92例孕产妇为对照组。观察组孕产妇在硬膜外阻滞麻醉下行无痛分娩,对照组孕产妇给予常规产科治疗,比较两组孕产妇的镇痛效果、宫缩时间及各产程时间、分娩方式、新生儿Apgar评分、产后2 h出血量(称重法测量)。结果观察组孕产妇的镇痛有效率明显高于对照组,差异有统计学意义(P<0.05);观察组孕产妇的第一产程时间明显短于对照组,差异有统计学意义(P<0.05);观察组孕产妇自然分娩率明显高于对照组,差异有统计学意义(P<0.05)。结论硬膜外阻滞麻醉用于无痛分娩可明显降低分娩所带来的疼痛,并能有效缩短第一产程时间,提高自然分娩率。
Objective To investigate the clinical effect of epidural anesthesia in painless labor.

Results The analgesic efficiency of pregnant women in the observation group was significantly higher than that of the control group (P <0.05). The time of the first stage of labor in the observation group was significantly shorter than that of the control group (P < 0.05). The rate of natural childbirth in observation group was significantly higher than that in control group (P <0.05). Conclusion Epidural anesthesia for painless labor can significantly reduce the pain caused by labor and can effectively shorten the time of the first stage of labor and improve the rate of natural delivery.
