摘要宫口开全立即屏气在国内已普遍存在，有研究表明会造成产妇体力消耗和酸中毒，而相关证明发现第二产程自主式屏气可促进自然分娩、缩短屏气时间、减少手术助产率。为改善妊娠结局，本文综述国内外研究自主屏气对分娩结局、积极屏气时间、盆底功能、满意度的影响，从而为促进人性化分娩提供实践依据。

abstractsIt is common that we tell the women to push when cervical dilation is ten centimeters, while studies have shown that will cause maternal physical consumption and acidosis. Relevant researches found spontaneous pushing can promote natural childbirth, shorten pushing time, and reduce the operation rate of delivery. To improve pregnancy outcomes, this paper reviews the domestic and foreign research of spontaneous pushing about delivery outcomes, positive pushing time, influence of the pelvic floor function, degree of women satisfaction. Supporting spontaneous pushing and encouraging women to choose their own method of pushing should be accepted as best clinical practice.
