摘要
目的:探讨双侧阴部神经阻滞麻醉配合无保护会阴接生法在初产妇自然分娩中的应用效果。方法:将2015年10月至2016年5月在我院进行自然分娩的150例初产妇随机分为观察组(n=75)与对照组(n=75)。为对照组产妇采用传统的保护会阴接生法进行助产,为观察组产妇采用双侧阴部神经阻滞麻醉配合无保护会阴接生法进行助产,然后对比分析两组产妇发生会阴撕裂、进行会阴侧切的情况、第二产程的时间、产后的出血量、其新生儿窒息的发生率及住院的时间。结果:两组产妇均未发生Ⅲ度与Ⅳ度会阴撕裂。与对照组产妇相比,观察组产妇会阴撕裂的总发生率及会阴侧切率均较低,差异有统计学意义(P<0.05)。与对照组产妇相比,观察组产妇第二产程的时间及住院的时间均较短,差异有统计学意义(P<0.05)。两组产妇产后的出血量及其新生儿窒息的发生率相比较差异无统计学意义(P>0.05)。结论:在初产妇进行自然分娩时采取双侧阴部神经阻滞麻醉与无保护会阴接生法对其进行助产可显著降低其会阴撕裂的发生率及会阴侧切率,缩短其第二产程的时间及住院的时间。
Objective Study effect of bilateral pudendal nerve block anesthesia with application of unprotected perineum delivery in natural delivery of primipara. Methods Randomly divide primipera in 150 cases in our hospital in experimental group （75 cases）and control granp（75 cases）.Deliver for control group with normal protection of perineum delivered method, deliver for experimental group with unprotected perineum delivery .Compare maternal perineal laceration, episiotomy, pain degree, second stage of birth process time, postpartum hemorrhage, newborn asphyxia rate and hospitalization time of two groups. Results The experimental group maternal perineal tear rate and episiotomy rate were significantly lower than the control group （P 〈 0.05）. Pain degree of experimental group was significantly lower than that of control group （P 〈 0.05）. Hospitalization time and birth process time of experimental group is significantly shorter than the control group （P 〈 0.05）. postpartum hemorrhage and newborn asphyxia rate of two group were no significant difference （P ：〉 0.05）. Conclusions Apply bilateral pudendal nerve block anesthesia with unprotected perineum delivery in natural delivery of primipara can reduce maternal perineal tear rate and episiotomy rate of primipara, and shorten the second stage birth process time.
