目的:探讨阴部管内神经阻滞麻醉配合无保护会阴接生的效果。方法:回顾性分析怀孕37~42周经阴道头位分娩的初产妇80例,按照是否采用双侧阴部管内神经阻滞麻醉分成麻醉组和对照组,比较2组产妇的疼痛程度、会阴裂伤严重程度。结果:麻醉组的疼痛程度明显低于对照组,麻醉组的会阴完整率高于对照组,差异均有统计学意义(P<0.05)。结论:阴部管内神经阻滞麻醉能有效地松驰会阴组织肌肉,减轻产妇分娩时及缝合时的疼痛,减少会阴部的裂伤,提高无保护会阴接生的成功率,促进自然分娩。
Objective: To explore the effect of intracranial nerve block anesthesia combined with unprotected perineal delivery. Methods: A retrospective analysis of 80 pregnant women 37 to 42 weeks of vaginal head delivery of primiparae, according to whether the use of bilateral genitals nerve block anesthesia into anesthesia group and control group, compared the two groups of maternal pain, perineal laceration severity. Results: The pain in the anesthetic group was significantly lower than that in the control group. The perineal complete rate in the anesthetic group was significantly higher than that in the control group (P <0.05). Conclusion: Nerve block anesthesia can effectively relax the perineal tissue muscles, relieve pain during delivery and suture, reduce perineal laceration, improve the success rate of unprotected perineal delivery, and promote natural childbirth.
