不同年龄段初产妇不同分娩方式后盆底肌力的变化

Changes of pelvic floor muscle strength in primiparas in different ages after different delivery modes

目的:分析不同年龄段初产妇不同分娩方式后盆底肌力的变化及临床意义。方法:以2016年8月至2018年8月秦皇岛市妇幼保健院收治的160例初产妇为研究对象,比较无保护接生及传统接生初产妇产后6周盆底肌力变化,并观察不同年龄段无保护接生初产妇及传统接生初产妇盆底肌力变化情况。结果:无保护接生初产妇年龄、BMI、文化程度、职业、产程及新生儿体重与传统接生初产妇相比差异无统计学意义(P>0.05);无保护接生组盆底肌力强度评分、前静息状态、最大收缩力、持续收缩力、后静息状态均较传统接生组明显高,差异有统计学意义(P<0.05);23~30岁无保护接生初产妇产后6周盆底肌力明显优于<23岁、>30岁初产妇,差异有统计学意义(P<0.05);且23~30岁传统接生初产妇产后6周盆底肌力明显优于<23岁、>30岁初产妇,差异有统计学意义(P<0.05)。结论:年龄、分娩方式均影响初产妇盆底肌力,年龄<23岁或>30岁初产妇产后盆底肌力降低更为明显,而无保护接生初产妇产后盆底肌力明显改善,或可建议为<23岁或>30岁初产妇行无保护接生分娩。

Objective:To analyze the changes and clinical significance of pelvic floor muscle strength in primiparas in different age levels after different delivery modes.Methods:A total of 160 primiparas who were admitted to the hospital from August 2016 to August 2018 were enrolled in this study.The changes of pelvic floor muscle strength were compared in primiparas of unprotected delivery and traditional delivery at 6 weeks after delivery.Changes in pelvic floor muscle strength of primiparas of unprotected delivery and traditional delivery in different age levels were observed.Results:There was no significant difference in age,BMI,education level,occupation,labor and neonatal weight between primiparas of unprotected delivery and traditional delivery (P>0.05).The score of pelvic floor muscle strength,the anterior resting state,maximum contraction force,continuous contraction force and post1706 resting state of the unprotected delivery group were significantly higher than those of the traditional delivery group (P<0.05).The pelvic floor muscle strength of 23 to 30 years old primiparas of unprotected delivery at 6 weeks after delivery was significantly better than that aged less than 23 years old and greater than 30 years old primiparas (P<0.05).The pelvic floor muscle strength of 23 to 30 years old primiparas of traditional delivery at 6 weeks after delivery was significantly better than that aged less than 23 years old and greater than 30 years old primiparas (P<0.05).Conclusion:Both age and delivery mode affect the pelvic floor muscle strength of the primipara.The decrease of pelvic floor muscle strength in primiparas aged less than 23 years old and greater than 30 years old is more obvious.The pelvic floor muscle strength is obviously improved in primiparas of the unprotected delivery after delivery.It is recommended in clinical obstetrics and gynaecology to promote unprotected delivery for primipara aged less than 23 years old and greater than 30 years old.
