Effects Of Different Delivery Modes On Female Pelvic Floor Muscle Strength And Therapeutic Effect Of The Biofeedback Combined With Electrostimulation On Pelvic Floor

Objective:To analyze the effects of different delivery modes on female pelvic floor muscle strength in the early postpartum period and the important significance of biofeedback combined with electrostimulation on restoring female pelvic floor muscle strength.Methods:450 cases of primipara who delivered and had the follow-up at 6~8 weeks after delivery in the Department of Gynecology and Obstetrics of Lanzhou University Second Hospital from January 2013 to April 2015 were selected as study objects, and then they were divided into cesarean section group(204 cases), transit cesarean delivery group(24 cases), perineal protection group(59 cases) and episiotomy group(163 cases), pelvic floor muscle strength assessments by pelvic floor myoelectricity physiologic instrument were performed in the four groups, 42 cases of pelvic floor dysfunction undergoed the therapy of biofeedback combined with electrostimulation and then pelvic floor muscle strength assessments were performed again.Results:1.The composition ratio of higher type on the former resting state in cesarean section group(71.57%) was statistically significantly higher than in episiotomy group(47.24%) and the averaged electromyogram(AEMG) of higher type in cesarean section group was statistically significantly higher than in perineal protection group and episiotomy group, differences were of statistical significance(P<0.05).2.The composition ratio of lower type on the fast pelvic floor muscle fiber in perineal protection group(81.36%) and episiotomy group(74.23%) was statistically significantly higher than in cesarean section group(46.57%) and the AEMG of lower type in episiotomy group was statistically lower than in cesarean section group, differences were of statistical significance(P<0.05).3.The composition ratio of lower type on the mixed pelvic floor muscle fiber in perineal protection group(91.53%) and episiotomy group(92.64%) was statistically significantly higher than in cesarean section group(73.53%) and the AEMGs of lower type in those were statisticallylower than in cesarean section group, differences were of statistical significance(P<0.05).4.The composition ratio of lower type on the slow pelvic floor muscle fiber in episiotomy group(89.57%) was higher than in cesarean section group(75.98%) and the AEMG of lower type in cesarean section group was statistically higher than in the rest of groups, differences were of statistical significance(P<0.05).5.The composition ratio of higher type on the latter resting state in cesarean section group(72.55%) was statistically significantly higher than in perineal protection group(49.15%) and episiotomy group(49.08%) and the AEMG of higher type in cesarean section group was statistically significantly higher than in perineal protection group and episiotomy group,differences were of statistical significance(P<0.05).6.There was no statistically significant difference when compared perineal protection group and episiotomy group in all the test indicators(P>0.05).7.After biofeedback combined with electrostimulation therapy, the composition ratio of lower type on the fast, mixed and slow pelvic floor muscle fiber were statistically significantly lower and the AEMGs of fast, mixed and slow pelvic floor muscle fiber were statistically significantly better,differences were of statistical significance(P<0.05).Conclusions:1.Cesarean section made the female pelvic floor muscle tighter in the resting state, so we should pay more attention to the follow-up and rehabilitation treatment in the early postpartum period after cesarean section.2.The damage caused by perineal protection and episiotomy on female pelvic floor muscle strength was more serious then cesarean section.3.There was no statistically significant difference on the damage caused by perineal protection and episiotomy on female pelvic floor muscle strength and we should select episiotomy after comprehensive assessment.4.The therapy of biofeedback combined with electrostimulation has important clinical significance on restoring female pelvic floor muscle strength and we should promote it.
