Objective To explore the effect of vaginal biofeedback electrical stimulation combined with Kegel training on delivery outcomes and postpartum pelvic floor muscle recovery.Methods Totally 300 pregnant women from January 2015 to January 2016 in Guigang Maternal and Child Health Care Hospital of Guangxi Zhuang Autonomous Region were randomly divided into group A,B and C,with 100 cases in each group.Group A was treated with Kegel training in pregnancy and postpartum;group B was treated with vaginal electrical stimulation in postpartum for 1 month;group C was treated with vaginal biofeedback electrical stimulation combined with Kegel training.Electric potential,fiber fatigue degree,contractility of pelvic floor muscle and pelvic organ prolapsed quantification(POP-Q) were measured;occurrences of nocturia,constipation,urinary incontinence and delivery outcomes were recorded.Results In group C,mean electric potential and fiber fatigue degree of pelvic floor muscle were significantly better than those in group A and group B[(15.4 ±2.5) μV vs (10.6 ±2.1),(12.5 ±2.2) μV;(0.00 ± 0.01) ％ vs (-0.01 ± 0.02) ％,(-0.01 ± 0.01) ％] (P ＜ 0.05);contractility of pelvic floor muscle deep layer fiber Ⅰ,deep layer fiber Ⅱ,superfacial layer fiber Ⅰ and superfacial layer fiber Ⅱ were significantly higher than those in group A and group B [(3.6 ± 0.8) vs (2.2 ± 1.1),(3.3 ± 1.1);(3.6 ±1.2) vs (2.4±1.2),(3.3±1.2);(3.4±0.9) vs(2.1±0.7),(3.0±0.9);(3.6±1.0) vs (2.2±1.3),(3.3 ± 1.1)] (P ＜ 0.05).After treatment,POP-Q in group B was significantly better than that in group A;POP-Q in C group was significantly better than that in group A and group B(P ＜0.05).In group C,incidences of nocturia and urinary incontinence were significantly lower than those in group A and group B [24.0％ (24/100) vs 44.0％ (44/100),32.0％ (32/100);12.0％ (12/100) vs 28.0％ (28/100),22.0％ (22/100)] (P ＜0.05).Cesarean section rates in group B and group C were significantly lower than that in group A[13.0％ (13/100),12.0％ (12/100) vs 30.0％ (30/100)] (P ＜ 0.05).Conclusion Biofeedback vaginal electrical stimulation combined with Kegel training can improve delivery outcomes,and it can effectively promote the functional recovery of pelvic floor muscle.%目的 研究生物反馈阴道松弛电刺激联合Kegel训练对孕产妇分娩结局以及产后盆底肌恢复情况的影响.方法 选择2015年1月至2016年1月在广西壮族自治区贵港市妇幼保健院分娩的300名孕产妇作为研究对象.按照随机数字法分为A、B、C3组,各100名.A组孕期及产后采用Kegel训练;B组产后采用阴道松弛电刺激疗法治疗1个月;C组在进行孕期及产后Kegel训练的同时进行产后生物反馈阴道松弛电刺激疗法,治疗1个月.治疗结束后,比较3组孕产妇的盆底肌电位均值、盆底肌纤维疲劳度、盆底肌收缩力、治疗前后盆腔器官脱垂定量(POP-Q)分度;对孕产妇的夜尿、便秘、尿失禁发生情况以及分娩结局进行统计分析.结果 C组孕产妇的盆底肌电位均值明显高于A组和B组,盆底肌纤维疲劳度明显优于A组和B组,差异有统计学意义[(15.4±2.5)μV比(10.6±2.1)、(12.5±2.2) μV,(0.00±0.01)％比(-0.叭±0.02)％、(-0.01±0.01)％](P＜0.05);C组孕产妇的盆底肌深层与浅层Ⅰ类及Ⅱ类肌纤维的收缩力明显高于A组和B组,差异有统计学意义[深层Ⅰ类:(3.6±0.8)比(2.2±1.1)、(3.3±1.1),深层Ⅱ类:(3.6±1.2)比(2.4±1.2)、(3.3±1.2);浅层Ⅰ类:(3.4±0.9)比(2.1±0.7)、(3.0±0.9),浅层Ⅱ类:(3.6±1.0)比(2.2±1.3)、(3.3±1.1)](P＜0.05).治疗后B组孕产妇的POP-Q分度情况明显优于A组,C组产妇的POP-Q分度情况明显优于A组和B组,差异均有统计学意义(均P ＜0.05).C组孕产妇夜尿及尿失禁的发生率明显低于A组和B组,差异有统计学意义[24.0％(24/100)比44.0％ (44/100)、32.0％(32/100),12.0％(12/100)比28.0％ (28/100)、22.0％ (22/100)] (P ＜0.05).B组、C组孕产妇的剖宫产率明显低于A组,差异有统计学意义[13.0％ (13/100)、12.0％ (12/100)比30.0％ (30/100)] (P ＜0.05).结论 生物反馈阴道松弛电刺激联合Kegel训练对于改善孕产妇的分娩结局具有一定的帮助,而且能够有效促进产后盆底肌功能的恢复.
