Abstract:
Objective To explore the effect of exogenous hormones on the pelvic floor function in delivery of term pregnancy using transvaginal 3D ultrasound.Methods Ninety puerperae delivered transvaginally were classified into three groups according to exogenous hormones,natural labor group (n =30),oxytocin group (n =30) and prostaglandin E2 group (n=30).Hiatal diameter and area at resting,Valsalva,levator ani muscle maximum contraction states were obtained in hiatal images and were compared among 3 groups in 42 days postpartum.Results There were no significant differences of hiatal diameter and area at resting,Valsalva,levator ani muscle maximum contraction state between natural labor group and oxytocin group (all P＞0.05).There were significant differences of hiatal diameter and area at resting,Valsalva,levator ani muscle maximum contraction state between prostaglandin E2 group and natural labor group,oxytocin group (all P ＜0.05).Conclusion Different exogenous hormones have different effects on the pelvic floor function in delivery of term pregnancy.The injury of the pelvic floor of using prostaglandin E2 is bigger than natural labor and using oxytocin.And the use of exogenous oxytocin is not significant correlated with pelvic floor function injury.
