阴道分娩孕产妇不同时期盆底肌功能锻炼对其功能恢复的影响

目的探讨阴道分娩孕产妇不同时期盆底肌功能锻炼对其功能恢复的影响。方法选择正常孕产妇156例，分为产前组50例，盆底肌肉锻炼自孕28周～分娩前；产后组52例，盆底肌肉锻炼自产后第3天～产后3个月；全程组54例，盆底肌肉锻炼自孕第28周．产后3个月；另设对照组55例，未进行盆底肌肉锻炼，比较分析四组产前、产后3个月盆底肌张力变化。结果经产前进行盆底肌肉锻炼后，产前组和全程组阴道收缩时间、VRP、VSP较产后组和对照组明显改善，差异具有统计学意义（P〈0．05）；经盆底肌肉锻炼后，全程组孕产妇阴道收缩时间明显长于其他i组，VRP、VSP高于其他三组（P〈0．05）；产前组和产后组阴道收缩时间、VRP、VSP差异无统计学意义（P〉0．05），但均高于对照组（P〈0．05）。结论孕产妇尽早进行盆底肌肉锻炼且持续时间至产后3个月能最大限度地保持和恢复盆底肌功能恢复，值得临床应用推广。

Effects of different periods of pelvic floor muscle exercise on the recovery of vaginal delivery of maternal pelvic floor muscle function

Objective To investigate the effect about pelvic floor muscle exercises in different periods on pelvic floor muscle function recovery vaginal delivery in pregnant women. Methods We seleeted 156 cases of normal pregnant women, they were randomly divided into prenatal group（n = 50）,who done pelvic floor muscle exercises from 28 preg- nancy weeks to delivering; postpartum group（n = 52） who done pelvic floor muscle exercises from postpartum third to postpartum 3 months; whole group （n = 54） who done pelvic floor muscle exercises from 28 pregnancy weeks to post- partum 3 months, control group （n = 55） who didn＇t pelvic floor muscle exercises, prenatal, postpartum 3 months pelvic floor muscle tension of the four groups were comparativly analysised. Results After antenatal pelvic floor muscle exercises, the vaginal contraction time, VRP, VSP of prenatal group and whole group were improved significantly than postnatal group and control group（P 〈 0.05）. After pelvic floor muscle exercises, the maternal vaginal contraction time of whole group was significantly longer than the other 3 groups, VRP, VSP was higher than the other 3 groups（P 〈 0.05）; the vaginal contraction time of prenatal group and postpartum group, VRP, VSP had no significant difference （P 〉 0.05）, but were significantly higher than those in control group （P 〈 0.05）. Conclusion Maternal early do pelvic floor muscle exercises and continue to postpartum 3 months can maximally maintain and restore pelvic floor muscle function recov- ery, it is worthy of clinical application.
