目的观察双侧阴部神经阻滞在自然分娩中的应用效果。方法选取2013年6月-2014年6月在医院行自然分娩的低危初产妇602例,根据不同身体素质与要求分为观察组308例和对照组294例,对照组产妇予局部浸润麻醉,观察组产妇予阴部神经阻滞,并观察2组镇痛效果。结果观察组镇痛总有效率为83.18%明显高于对照组的69.05%(P<0.05),观察组会阴完整率为28.2%明显高于对照组的11.6%(P<0.05),会阴裂伤及侧切分别为12.3%、59.4%低于对照组的15.3%、73.1%(P<0.05);观察组缝合时间(23.5±2.93)min明显低于对照组的(39.2±1.86)min(P<0.05),观察组新生儿Apgar评分8~10分率97.08%明显高于对照组的91.84%,差异均有统计学意义(P<0.05)。结论阴部神经阻滞可明显减轻产妇痛苦,可广泛应用于产科自然分娩。
Objective To observe the effect of bilateral pudendal nerve block in natural childbirth. Methods Sixty-two cases of low-risk primipara were selected from June 2013 to June 2014 in our hospital. According to different physical quality and requirements, we divided them into observation group (308 cases) and control group (294 cases). The control group was given partial infiltration anesthesia, Observation group maternal to the genitals nerve block, and observed two groups analgesic effect. Results The total effective rate of analgesia in the observation group was 83.18%, which was significantly higher than that in the control group (P <0.05). The perineal completeness rate in the observation group was 28.2%, significantly higher than that in the control group (11.6%, P <0.05) (23.5 ± 2.93) min in the observation group were significantly lower than those in the control group (39.2 ± 1.86) min (P < 0.05). In the observation group, Apgar score of 8-10 was 97.08% higher than 91.84% of the control group, with significant difference (P <0.05). Conclusion Pussy nerve block can significantly reduce the pain of maternal, can be widely used in obstetric natural childbirth.
