Effects Of Balloon Bionics Combined With Non-invasive Midwifery On Pelvic Floor Function

Objective:A new midwifery technology was constructed by using the combination of balloon bionics instrument with non-invasive midwifery technique in vaginal delivery.And this new kind of midwifery,the traditional perineal protection midwifery group and single non-invasive technology group would constitute three different modes of delivery.After the follow-up of postpartum health examination,the pelvic floor functions of the three groups were evaluated and compared.The pelvic floor muscle strength scoring and grading three months and six months after delivery,and the stress urinary incontinence situation three months and six months after delivery were analyzed comprehensively.The pelvic floor organ structure and function detection after delivery was evaluated as an innovative point.To explore the application of balloon bionics combined with non-invasive midwifery technology in vaginal delivery under natural posture,the clinical value can reduce the injury of the soft birth canal,and provide effective solutions for effectively improving the recovery of postpartum pelvic floor function.Methods:1.Statistical data of all subjects:age,gestational age,pre-pregnancy body mass index,pelvic floor muscle tension during pregnancy.141 primipara with28 gestational weeks were confirmed,aged 20～33 years,with an average age of（27.60±3.32）years.The uterine height and abdominal circumference were within the normal range,excluding those who delivered by cesarean section,and those who kept vaginal delivery were given informed consent.Pelvic floor muscle strength and stress urinary incontinence were measured.2.Obstetric follow-up excluded late pregnancy complications and delivery in another hospital.There were 121 cases of vaginal delivery in our hospital.The gestational age ranged from 37 to 41⁺⁶weeks and the fetal weight ranged from 2500 to 3950 g.All of them were normal head vaginal delivery and full-term single live births.3.7 cases of cesarean section and dystocia midwifery,4 cases of second degree perineal laceration,1 case of uterine cavity remnants and 2 cases of postpartum missing follow-up were excluded.In this study,48 cases of pregnant and lying-in women were used as observation group（group A）.They received natural posture,balloon bionics and non-invasive midwifery technology in assisted vaginal delivery.Another 25 cases of pregnant and lying-in women were taken as control group by single noninvasive technique（group B）.34 cases of pregnant and lying-in women received traditional midwifery as control group（group C）.4.Inclusion criteria for postpartum study:107 cases of all cases originated from primipara women with 28 weeks gestational age.Balloon bionics combined with non-invasive midwifery,single non-invasive technique and traditional midwifery were used for vaginal delivery.After vaginal delivery,women were examined in gynecological clinic of our hospital at 3 and 6 months postpartum.Pelvic floor organ function was screened again.Stress urinary incontinence,pelvic floor muscle strength and pelvic organ prolapse were evaluated comprehensively.Results:1.Comparison of pelvic floor muscle strength at 3 months,6 months after delivery in three groups of parturients with different delivery methods:（1）The pelvic floor muscle strength of the parturients was normal at 28weeks of gestation.（2）Three months after delivery:In the comparison of the number of continuous contractions of type II muscle fibers within 15 seconds,there was difference between single noninvasive technique and traditional midwifery（P<0.05）;there was significant difference between balloon bionics combined with noninvasive midwifery and traditional midwifery（P<0.01）.In the comparison of the average vaginal pressure of type II muscle fibers,there was significant difference between balloon bionics combined with non-invasive midwifery and traditional midwifery（P<0.01）;there was difference between single non-invasive technique and traditional midwifery（P<0.05）.（3）Six months after delivery:Continuous contraction time of type I muscle fibers in 6 seconds,there was difference between the balloon bionics combined with non-invasive midwifery and the single non-invasive technique（P<0.05）;there was significant difference between the balloon bionics combined with non-invasive midwifery and the traditional midwifery（P<0.01）;there was difference between the single non-invasive technique and the traditional midwifery（P<0.05）.In the comparison of the number of continuous contraction of type II muscle fibers within 6 seconds,there was difference between balloon bionics combined with non-invasive midwifery and single non-invasive technique（P<0.05）;there was difference between single non-invasive technique and traditional midwifery（P<0.05）;there was significant difference between balloon bionics combined with non-invasive midwifery and traditional midwifery（P<0.01）.In the comparison of the average vaginal pressure of type II muscle fibers,there was difference between the airbag bionics combined with non-invasive midwifery and the single non-invasive technique（P<0.05）;there was difference between the single non-invasive technique and the traditional midwifery（P<0.05）;there was significant difference between the airbag bionics combined with non-invasive midwifery and the traditional midwifery（P<0.01）.（4）.To compare the self-repeated measurements of prenatal and postpartum women at three different stages.In pelvic floor muscle function,the traditional midwifery method decreased significantly 3 months and 6months after delivery（P<0.05）.2.Comparison of stress urinary incontinence at 3 and 6 months after delivery in three groups of parturients with different delivery modes:（1）Non-stress urinary incontinence of pregnant women at 28 weeks of gestation.（2）Three months after delivery:1 case of mild stress urinary incontinence（2.08%）was treated with balloon bionics combined with non-invasive midwifery,1 case of mild stress urinary incontinence（4.00%）was treated with single non-invasive technique,and 5 cases of mild stress urinary incontinence（14.71%）were treated with traditional midwifery.Compared with the traditional midwifery method,the airbag bionics combined with non-invasive midwifery method has statistical significance（P<0.05）.（3）Six months after delivery:1 case of mild stress urinary incontinence（2.08%）was treated with balloon bionics combined with non-invasive midwifery,1 case of mild stress urinary incontinence（4.00%）was treated with single non-invasive technique,6 cases of mild stress urinary incontinence and1 case of moderate stress urinary incontinence（20.59%）were treated with traditional midwifery.Compared with the traditional midwifery method,the airbag bionics combined with non-invasive midwifery method had significant difference（P<0.01）.Compared with the traditional midwifery method,the single noninvasive technique method had difference（P<0.05）.（4）There was no significant difference in self-repeated measurements of three months and six months after delivery between balloon bionics combined with non-invasive midwifery,single non-invasive technique and traditional midwifery（P>0.05）.3.Comparisons of pelvic organ prolapse among three groups of postpartum women with different delivery modes at 3 and 6 months postpartum.There was no prolapse of genitourinary tract in 3 and 6 months after delivery in three groups.Conclusion（s）:By comparing traditional midwifery and single non-invasive technology with natural posture and using balloon bionics combined with non-invasive midwifery technology to construct a new type of midwifery technology in vaginal delivery,non-invasive midwifery with balloon biomimetic device was used to achieve ideal muscle tension score and grading at 3 and 6 months after delivery,it can reduce stress urinary incontinence 3 and 6 months after delivery,and significantly improve the day of vaginal delivery,rehabilitation function of posterior pelvic floor organs and tissues can improve women’s healthy quality of life.
