分娩镇痛启动时机对分娩结局影响的Meta分析

Meta-analysis of the Effect of Timing of Labor Analgesia Initiation on Labor Outcomes

目的探讨分娩镇痛时机对分娩结局的影响。方法在国内外各大知名数据库检索关于分娩镇痛启动时机相关文献,对文献进行筛选,并用RevMan 5.3.5软件进行分析。结果共纳入14篇文献,证据强度中等。结论目前并无研究表明早期实施分娩镇痛会导致分娩不良结局,反而可以缩短第一产程时间。因此,为了提升产妇分娩舒适度,可以不必按照宫口大小而是根据产妇意愿实施分娩镇痛。

Objective To explore the effect of timing of analgesia in labor on the outcome of labor.Methods The literature on the timing of onset of labor analgesia was searched in well-known databases at home and abroad,and the lit-erature was screened and analyzed with RevMan 5.3.5 software.Results A total of 14 literatures were included,with moderate evidence strength.Conclusion At present,no studies have shown that early implementation of labor analgesia will lead to adverse outcomes in labor,but can shorten the time of the first stage of labor.Therefore,in order to improve the comfort of childbirth,labor analgesia can be implemented according to the will of the mother rather than according to the size of the uterine opening.
