Clinical significance of different delivery modes based on ultrasound monitoring on postpartum pelvic floor structure and pelvic floor muscle strength repair
Objective To explore the significance of different delivery modes based on ultrasound monitoring on the postpartum pelvic floor structure and pelvic floor muscle strength repair.Methods A total of 168 primiparas who gave birth in Jiaozhou Central Hospital of Qingdao from March 2021 to March 2023 were selected as research subjects.Among the patients,98 cases with vaginal delivery were included in vaginal delivery group,32 cases undergoing vaginal midwifery were enrolled as vaginal midwifery group,and 38 cases with cesarean section were assigned as cesarean section group.All the three groups received postpartum rehabilitation treatment.Pelvic floor ultrasound examination and pelvic floor muscle strength examination were performed before treatment and after 6 weeks of treatment.The ultrasound indicators[posterior vesicourethral angle(PUA),urethral tilt angle(UTA)and bladder neck position(BNP)under valsalva motion of holding the breath downward and the resting state]and pelvic floor muscle strength(type Ⅰ muscle continuous contraction force,type Ⅱ muscle maximum contraction force)were compared among the three groups.Results Under the Valsalva motion of holding the breath downward,the PUA,UTA and BNP before treatment and after 6 weeks of rehabilitation treatment were expressed as vaginal midwifery group＞vaginal delivery group＞cesarean section group(P＜0.05),and the differences of the above indicators before and after treatment were shown as cesarean section group＞vaginal delivery group and vaginal midwifery group(P＜0.05).Under the resting state,the PUA and UTA showed vaginal midwifery group＞vaginal delivery group＞cesarean section group(P＜0.05)while the BNP was shown as vaginal midwifery group＜vaginal delivery group＜cesarean section group(P＜0.05),and the differences of the above three indicators before and after treatment indicated that cesarean section group＞vaginal delivery group and vaginal midwifery group(P＜0.05).The type Ⅰ muscle continuous contraction force and type Ⅱ muscle maximum contraction force were manifested as vaginal midwifery group＜vaginal delivery group＜cesarean section group(P＜0.05),and the differences of the above two indicators before and after treatment were shown as cesarean section group＞vaginal delivery group and vaginal midwifery group(P＜0.05).Conclusions There are pelvic structural changes and decreased pelvic floor muscle strength in postpartum women with different delivery modes,and vaginal midwifery has the greatest effect,followed by vaginal delivery and cesarean section.The postpartum pelvic floor repair speed of puerperae with cesarean section is faster than that in vaginal delivery.
