适度保护会阴技术对降低初产妇会阴侧切率的效果评价

目的探讨适度保护会阴技术对降低初产妇会阴侧切率的临床效果。方法选取经阴道分娩并实施传统接生技术的初产妇350例作为对照组，经阴道分娩并实施适度会阴保护技术的初产妇366例作为观察组。比较2组初产妇的会阴裂伤发生率、会阴侧切率、第二产程时间、产后2 h出血量。结果观察组产妇会阴裂伤程度明显优于对照组（P < 0.01），会阴侧切率明显低于对照组（P < 0.01），第二产程时长和产后2 h出血量均明显高于对照组（P < 0.01）。2组均无新生儿窒息发生。结论实施适度保护会阴技术能有效减少初产妇会阴裂伤和会阴侧切率，第二产程时间和产后2 h出血量均在正常值范围内，不会提升新生儿窒息发生率，值得临床推广。

Evaluation of the effects of appropriate perineal protection technique in reducing the rate of lateral perineal resection in primipara

ObjectiveTo investigate the clinical effects of appropriate perineal protection technique in reducing the rate of lateral perineal resection among primiparas.MethodsA total of 350 primiparas who delivered vaginally and performed traditional delivery techniques were selected as the control group, and 366 primiparas who delivered vaginally and performed moderate perineal protection techniques were selected as the observation group.The incidence rate of perineal laceration, rate of lateral perineectomy, second stage of labor and postpartum 2 h blood loss were compared between two groups.ResultsThe degree of perineal laceration in observation group was significantly better than that in control group(P < 0.01), the rate of perineal lateral resection in observation group was significantly lower than that in the control group(P < 0.01), and the duration of the second stage of labor and postpartum 2 h blood loss in observation group were significantly higher than that in the control group(P < 0.01).No neonatal asphyxia occurred in two groups.ConclusionsThe implementation of moderate perineal protection technology can effectively reduce the rate of perineal laceration and lateral perineectomy of primiparas, the second stage of labor time and postpartum 2h blood loss are within the normal range, and will not increase the incidence rate of neonatal asphyxia, and which is worthy of clinical promotion.
