产后盆底表面肌电评估与相关因素分析

Assessment and related factors analysis of postpartum pelvic floor surface electromyography

目的应用盆底表面肌电生物反馈仪评估产后复查患者的盆底功能状况,分析相关因素对产后盆底功能的影响,为盆底功能障碍性疾病(PFD)的诊断和治疗提供理论依据。方法选取2017年11月-2018年10月在天津市南开医院进行产后复查的产妇92例,根据分娩方式、年龄、体质量指数(BMI)进行分组,分析比较组间盆底表面肌电值的差异。结果与剖宫产组相比,阴道分娩组盆底表面肌电值较低,盆底慢肌松弛的发生率较高,差异有统计学意义(P<0.05);较高年龄组、超重组与其对照相比,盆底功能状态差异无统计学意义(P>0.05)。结论阴道分娩产妇与剖宫产产妇相比,盆底功能较差。在一定范围内,年龄和超重对盆底功能无明显影响。

Objective The pelvic floor function was assessed by pelvic floor surface electromyography biofeedback instrument,and the related factors were analyzed to provide theoretical basis for the diagnosis and treatment of pelvic floor dysfunction disease(PFD).Methods 92 postpartum patients who underwent postpartum reexamination in Tianjin Nankai Hospital from November 2017 to October 2018 were selected and divided in different groups according to the delivery mode,the age and the body mass index(BMI),to analyze and compare the surface electromyographic values of pelvic floor between groups.Results Compared to the caesarean section group,the vaginal delivery group showed much lower surface electromyographic values and higher slow-muscle relaxation rate of pelvic floor,the differences were statistically significant(P<0.05).There were no significant differences between the different age and BMI groups(P>0.05).Conclusion Vaginal delivery patients have much worse pelvic floor function than caesarean section ones.Within a certain range,age and BMI had no significant effect on pelvic floor function.
