Abstract: ObjectiveTo systematically assess the effect of evidence-based nursing on labor outcomes among Chinese puerperae with natural childbirth and to provide evidences for clinic nursing.MethodsRelevant literatures were searched through Chinese databases such as Chinese National Knowledge Infrastructure(CNKI),Wanfang,and Weipu via internet according to the inclusion and the exclusion criteria.Note Express software was used in screening and duplicate checking of the literatures and RevMan 5.2 software was adopted in the analyses.ResultsA total of 14 studies were included in the study,with totally 2 028 participants in the intervention group and 1 984 in the control group.The results of meta-analysis showed that evidence-based nursing could shorten the time(in hour) of first stage of labor,with a mean difference(MD)of-2.3 and its 95% confidence interval(95%CI)of -2.60--2.01),the time of second stage of labor(MD=-0.41,95%CI:-0.54--0.28),and the time of third stage of labor(MD=-0.05,95%CI:-0.05--0.04).Moreover,the implementation of evidence-based nursing could significantly decrease the rate of neonatal asphyxia,with an odds ratio of 0.36(95%CI=0.27-0.4). ConclusionApplication of evidence-based nursing can shorten parturient labor time of natural childbirth and reduce the incidence of neonatal asphyxia and its clinical application should be promoted.
