目的探讨无保护会阴接生法在阴道分娩过程中的临床应用效果。方法选择2014年1~6月份符合入选标准实行无保护会阴接生法的阴道分娩产妇500例作为观察组,选择2013年同期同样标准实行传统保护会阴接生法的阴道分娩产妇500例作为对照组,比较2组会阴损伤、会阴伤口愈合情况、分娩不良结局等情况。结果 2组产妇的会阴侧切率、会阴完整率比较,差异有统计学意义(P<0.05),而产后出血率、新生儿窒息率、会阴伤口愈合率比较,差异无统计学意义(P>0.05)。结论无保护会阴接生法降低会阴侧切率、增加会阴完整率,减轻产妇会阴损伤程度,不增加分娩不良结局,减少助产人员的职业劳损。该方法操作简单、安全、有效,值得临床推广。
Objective To investigate the clinical effect of unprotected perineal birth in vaginal delivery. Methods 500 cases of vaginal delivery mothers who met the inclusion criteria in January to June 2014 undergoing unprotected perineal birth were selected as the observation group and 500 cases of vaginal delivery mothers who adopted the same standard of the same period of 2013 for vaginal delivery were selected as the control group 2 episodes of perineal injury, perineal wound healing, poor delivery and other circumstances. Results There were significant differences in episiotomy rate and perineal completeness between the two groups (P <0.05), but there was no significant difference in postpartum hemorrhage rate, neonatal asphyxia rate and perineal wound healing rate (P> 0.05 ). Conclusion The unprotected perineal birth reduction reduces the episiotomy rate of the perineum, increases the perineal completeness, reduces the severity of perineal injury, does not increase the adverse outcomes of childbirth, and reduces the occupational strain of midwives. The method is simple, safe and effective, worthy of clinical promotion.
