无保护会阴助产分娩对初产妇妊娠结局及自我效能的影响

Effect of Unprotected Perineal Assisted Delivery on Pregnancy Outcomes and Self-Efficacy in Primipara

目的:探讨无保护会阴助产分娩对初产妇妊娠结局及自我效能的影响。方法:选取2019年1—12月扬州大学附属医院收治的初产妇140例作为研究对象,根据随机数字表法分为对照组和观察组,各70例。对照组行常规助产,观察组行无保护会阴助产。比较两组会阴侧切情况及会阴撕裂程度、新生儿不良事件发生情况、自我效能。结果:观察组会阴侧切率低于对照组,差异有统计学意义(P=0.003)。观察组会阴Ⅰ度撕裂率高于对照组,Ⅱ度撕裂率低于对照组,差异有统计学意义(P<0.05);两组会阴Ⅲ度撕裂率比较,差异无统计学意义(P>0.05)。观察组新生儿不良事件发生率低于对照组,差异有统计学意义(P=0.009)。干预后,观察组期望量表和自我效能期望量表评分高于对照组,差异有统计学意义(P<0.001)。结论:无保护会阴助产可降低初产妇会阴侧切率、会阴撕裂程度及新生儿不良事件发生率,提高初产妇自我效能。

Objective:To investigate the effect of unprotected perineal assisted delivery on pregnancy outcomes and self-efficacy in primipara.Methods:A total of 140 primiparas admitted to Affiliated Hospital of Yangzhou University from January 2019 to December 2019 were selected as the study subjects.According to the random number table method,they were divided into control group and observation group,with 70 cases in each group.The control group underwent routine assisted delivery and the observation group underwent unprotected perineal assisted delivery.The rate of lateral episiotomy,the degree of perineal laceration,adverse neonatal events,and self-efficacy in two groups were compared.Results:The rate of lateral episiotomy in the observation group was lower than that in the control group,and the difference was statistically significant(P=0.003).The firstdegree perineal laceration rate in the observation group was higher than that in the control group,and the second-degree perineal laceration rate in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).There was no significant difference in the third-degree perineal laceration rate between the two groups(P>0.05).The incidence of adverse neonatal events in the observation group was lower than that in the control group,and the difference was statistically significant(P=0.009).After the intervention,the scores of the Expectation Scale and the Self-Efficacy Expectation Scale in the observation group were higher than those in the control group,and the difference was statistically significant(P<0.001).Conclusion:Unprotected perineal assisted delivery can reduce the rate of lateral episiotomy,the degree of perineal laceration and the incidence of neonatal adverse events,and improve the self-efficacy of primipara.
