子宫收缩力是产力的主要组成部分，能促进宫颈口扩张及胎先露下降，其作用贯穿于整个产程。当产程进入活跃期，机械刺激宫颈可加强子宫收缩力，加快窗口扩张速度、缩短产程。据此原理，肛查时反复按摩宫颈在加速产程、促进分娩方面可取得良好效果。我们在已往工作的基础上［’j Uterine contractility is a major component of productivity, can promote cervical dilatation and fetal exposure to decline, its role runs through the entire labor process. When the labor process into the active period, the mechanical stimulation of the cervix can enhance uterine contractility, speed up the expansion of the window, shorten the birth process. According to this principle, anal repeatedly massage the cervix in accelerating labor, to promote delivery can achieve good results. On the basis of our previous work, [j]
