目的探讨低危初产妇经阴道分娩会阴无侧切方式对母儿结局的影响。方法对2013年8月-2014年9月某院收治的经阴道分娩的产妇311例进行分析,选取其中符合纳入标准的232例低危初产妇,以会阴无侧切产妇159例作为观察组,行会阴侧切产妇73例为对照组,分别从会阴完整率、新生儿窒息率、第二产程平均时长、产后会阴疼痛情况进行对比分析。结果两组新生儿窒息发生率、会阴Ⅲ度裂伤发生率比较差异无统计学意义(P>0.05);在第二产程用时上,观察组平均37.95 min,对照组平均55.36 min;产后会阴疼痛情况上比较差异具统计学意义(P<0.05)。结论低危初产妇经阴道分娩会阴无侧切与会阴侧切分娩方式之间,会阴侧切并不能缩短第二产程,会阴无侧切法增加产妇的产后舒适感。主张会阴无侧切分娩法,避免常规会阴侧切术,降低会阴侧切率,促进产妇身心健康。
Objective To investigate the effect of perineal unilateral cleavage on maternal and infant outcomes in low-risk primipara. Methods 311 cases of vaginal delivery during August 2013 to September 2014 in a hospital were analyzed. Among them, 232 cases of low-risk primipara were selected, and 159 cases of unilateral meningeal episiotomy were selected as the observation group. Sixty-three women with episiotomy were selected as the control group. The perineal completeness rate, neonatal asphyxia rate, average length of the second stage of labor and postpartum perineal pain were compared and analyzed. Results The incidence of neonatal asphyxia and perineal third degree laceration in two groups had no significant difference (P> 0.05). In the second stage of labor, the observation group averaged 37.95 minutes and the control group averaged 55.36 minutes. The postpartum perineal pain The difference was statistically significant (P <0.05). Conclusion Low-risk primiparous vaginal delivery during perineal unilateral and episiotomy lateral delivery mode, episiotomy and can not shorten the second stage of labor, perineal unilateral approach to increase postpartum comfort. Advocated perineal unilateral delivery method to avoid the routine perineal excision, reduce the perineal lateral incision rate and promote maternal physical and mental health.
