阴部神经阻滞麻醉联合局部浸润麻醉在第二产程中的应用

Application of Pudendal Nerve Block Anesthesia and Local inFiltration Anesthesia in the Second Stage of Labor

目的评价阴部神经阻滞麻醉联合局部浸润麻醉在第二产程中的应用。方法 200例初产妇在第二产程中用0.5%的利多卡因行双侧阴部神经阻滞麻醉联合局部浸润麻醉,另外200例初产妇在第二产程不进行麻醉,仅缝合时行局部浸润麻醉。结果联合麻醉组在第2产程的时间、侧切率、会阴裂伤程度、缝合时疼痛程度、时间和第3产程时间、产后2h出血量明显少于对照组,差异具有统计学意义P<0.05,两组组会阴肿胀、切口甲级愈合方面无显著差异P>0.05。结论阴部神经阻滞麻醉联合局部浸润麻醉能使盆底肌肉放松,降低会阴裂伤、会阴侧切率,提高其阴道分娩的积极性,且操作简单,安全,值得推广。

Objective To evalue the application of pundendal nerve block anesthesia and local infiltration anesthesia in the second-stage of labor. Method 200 caese of primipara during the second stage of labor with 0.5% lidocaine bilateral pudendal nerve block anesthesia combined with local infiltration anesthesia; Another 200 cases of primipara during the second stage of labor without anesthesia, only the suture after local infiltration anesthesia. Result Combined anesthesia group in the second stage of labor time, side of the cutting rate, perineal laceration, suture the degree of pain, time and the time of third stage of labor ,postpartum hemorrhage 2 hours was significantly less than that in the control group, the difference was statistically significant P〈0.05. Two groups of perineal swelling and incision healing, there was no significant difference between P〉0.05. Conclusion The application of pundendal nerve block anesthesia and local infiltration anesthesia can can make pelvic floor muscle relaxation, reduce perineal laceration, perineotomy rate, improve the enthusiasm of vaginal delivery, and the operation is simple, safe, ts worth popularizing.
