摘　　要：目的研究经阴道分娩及剖宫产分娩对产后妇女盆底肌力的影响。方法将184例产妇根据分娩方式分为剖宫产分娩组(n=59)、阴道自然分娩组(n=117)及产钳分娩组(n=8);于产后6～8周进行问卷调查,并应用Femiscan生物反馈治疗仪检测产后盆底肌力。同期选择20例年龄相当的已婚未育女性作为对照组。结果对照组妇女盆底肌力的各项指标均高于产后妇女,差异有统计学意义(P<0.05)。剖宫产分娩组产妇产后盆底肌力最强,产钳分娩组产妇产后盆底肌力最差,两组盆底肌肉活力值的差异有统计学意义(P<0.05)。剖宫产分娩组及阴道自然分娩组产后左右两侧盆底肌肉活力值的差异无统计学意义(P>0.05)。产钳分娩组产妇左右两侧盆底肌肉活力值比较,差异有统计学意义(P<0.05)。阴道自然分娩组产妇第一产程时间与产钳分娩组比较,差异无统计学意义(P>0.05);两组第二产程时间比较,差异有统计学意义(P<0.05)。结论阴道自然分娩产妇产后早期的盆底肌力与选择性剖宫产分娩产妇相当;产钳分娩产妇盆底肌力最差,可能与其第二产程时间过长有关。Objective To investigate the effects of vaginal delivery and caesarean sectionon on activity of pelvic floor muscles after delivery.Methods One hundred and eighty-four women were divided into caesarean section group（n=59）,vaginal delivery group（n=117） and forceps delivery group（n=8） according to the ways of delivery.Questionnaire survey was conducted 6 to 8 weeks after delivery,and the activity of pelvic floor muscles after delivery was measured by Femiscan feedback instrument.Another 20 age-matched nulliparas were selected as control group.ResultsThe parameters of activity of pelvic floor muscles in control group were significantly higher than those of postpartum women（P0.05）.The activity of pelvic floor muscles in caesarean section group was the highest,that in forceps delivery group was the lowest,and there were significant differences between two groups（P0.05）.There was no significant difference between the activity of left pelvic floor muscles and that of right pelvic floor muscles in caesarean section group and vaginal delivery group（P0.05）.There were significant differences between the activity of left pelvic floor muscles and that of right pelvic floor muscles in forceps delivery group（P0.05）.There was no significant difference in the duration of first stage of labor between vaginal delivery group and forceps delivery group（P0.05）,while there were significant differences in the duration of second stage of labor between two groups（P0.05）.Conclusion The activity of pelvic floor muscles in women with vaginal delivery is similar to that in women with caesarean section.The activity of pelvic floor muscles in women with forceps delivery is the lowest,which may be related to the prolonged duration of second stage of labor.
