目的评价阴道分娩前后盆底肌力。设计前瞻性重复测量研究。设主区医院。人口55例，初产妇25例，经产妇20例，并以10例择期剖宫产产妇为对照组。方法在分娩前分别于妊娠36~42周、产后3~8天、产后6~10周分别进行盆底肌力触诊、会阴测量和会阴部超声检查。主要观察指标：产后36~42周、产后3~8天、产后6~10周。结果阴道分娩后3~8天盆底肌力明显降低，剖宫产后盆底肌力无明显变化。产后6~10周，会阴部超声触诊和膀胱颈抬高与产前无明显差异，初产妇会阴测压显著降低，经产妇无明显变化。结论经阴道分娩后不久，盆底肌力受损，但多数产妇在两个月内恢复。
Objective To evaluate pelvic floor muscle strength before and after vaginal birth.Design Prospective repeated measures study.Setting Main district hospital.Population Fifty-five women: 25 primiparae and 20 multiparae following vaginal birth, and 10 women following elective caesarean delivery as a control group.Methods Pelvic muscle strength was evaluated by palpation, perineometry and perineal ultrasound before childbirth in the 36th to 42nd week of pregnancy, three to eight days postpartum and six to ten weeks postpartum.Main outcome measures Pelvic floor muscle strength on palpation, intravaginal squeeze pressure and vesical neck elevation during squeeze.Results Pelvic floor muscle strength is significantly reduced three to eight days postpartum in women following vaginal birth but not in women after caesarean delivery. Six to ten weeks later palpation and vesical neck elevation on perineal ultrasound do not show any significant differences to antepartum values, while intravaginal pressure on perineometry remains significantly lower in primiparae, but not in multiparae.Conclusions Pelvic floor muscle strength is impaired shortly after vaginal birth, but for most women returns within two months.
