182 例低危初产妇行无保护会阴接生技术的临床效果

目的探讨无保护会阴接生技术对低危阴道分娩初产妇会阴裂伤程度及分娩期并发症的影响。方法选择 2015 年 1~3 月， 阴道分娩且无会阴侧切指征的初产妇 182 例，随机分为 2 组，观察组 86 例，对照组 96 例，观察组在胎头着冠后实行无保护会阴接生技术；对照组则按照传统会阴保护接生技术，比较两组产妇的会阴完整率及裂伤程度、会阴水肿情况、产后 2 h 出血量及新生儿窒息情况。结果观察组的会阴完整率高于对照组（χ²=5.419，P＜0.05），会阴水肿发生率低于观察组（Z=-2.377，P＜0.05），差异有统计学意义，两组会阴裂伤程度（Z=-0.647，P＞0.05）、产后 2 h 出血量（Z=-0.423，P＞0.05）及新生儿窒息率（Z=-0.486，P＞0.05）， 差异无统计学意义。结论无保护会阴接生技术减轻了产妇会阴损伤程度，没有造成明显的分娩并发症，值得在临床推广。

Effect of unprotected perineum delivery technique in low risk primipara

ObjectiveTo explore the effect of unprotected perineum delivery technique in spontaneous vaginal delivery in low risk primipara. MethodsFrom January to March 2015 ,182 primipare with spontaneous vaginal delivery in the hospital with no episiotomy indication were randomly divided into observation group (n=86) and control group (n=96).Unprotected perineum delivery technique and routine delivery technique were adopted in the observation group and control group after the fetal head crowned. Perineal integrity rate, the degree of perineal laceration,perineal edema,the hemorrhage volume 2 h after delivery, newborn asphyxia situation were compared in two groups. ResultsTheperineal integrity rate was higher and perineal edema rate was lower in observation group than that in control group（P＜0.05）. No significant difference was detected in the degree of perineal laceration, the hemorrhage volume 2 h after delivery, newborn asphyxia situation between the two groups（P＞0.05）. ConclusionUnprotected perineum delivery technique can decrease the degree injury of perineum, with no labor complications.
