足月阴道试产失败转急诊剖宫产的回顾性分析

摘要

目的 研究足月阴道试产失败转急诊剖宫产的相关因素.方法 采用回顾分析,选取该院2014-2015年接诊的100例足月阴道试产失败转急诊剖宫产孕妇作为研究组,另选取100例阴道试产成功孕妇作为对照组,2组产妇均进行常规检查,检测并记录2组孕妇的身高、体质量增加、临产时体质量、年龄、孕周、体质量指数(BMI)、新生儿体质量等指标,以及分娩镇痛情况、临产发动方式及不同临产方式下孕妇的剖宫产指征等,并进行比较分析.结果 2组孕妇的身高、体质量增加、临产时体质量差异均无统计学意义(P>0.05).研究组孕妇的年龄、孕周、BMI值及新生儿体质量均明显高于对照组孕妇,差异有统计学意义(P<0.05).2组孕妇在胎盘早破、胎儿性别及受孕方式方面差异均无统计学意义(P>0.05).研究组孕妇使用宫缩素加强的比例明显高于对照组,而存在镇痛分娩的比例及自然临产发动的比例明显低于对照组,差异均有统计学意义(P<0.05).相对头盆不称组孕妇临产时BMI与新生儿体质量明显高于胎儿窘迫组和对照组,差异均有统计学意义(P<0.05);而3组孕妇的孕期体质量增加与临产时体质量比较,差异无统计学意义(P>0.05).结论 对于足月阴道试产孕妇而言,随着孕妇体质量、年龄、孕周及新生儿体质量增加等,其阴道试产成功率将有所下降,合理控制临产时的BM I值将有利于提高孕妇阴道试产的成功率.%Objective To study retrospectively of term vaginal failure emergency cesarean section and vaginal delivery in preg-nant women .Methods Retrospective analysis of 100 cases of full-term vaginal delivery in our hospital during January 2014 to De-cember 2015 were the failure of emergency cesarean section in pregnant women as the study group ,and selected 100 cases of vaginal delivery in pregnant women as control group were studied ,two groups were routine inspection ,the height ,the weight of pregnant women .Detected and recorded the two groups of pregnant women increased the time of birth weight ,pregnant women ,maternal age ,gestational age ,birth weight ,BMI value and other indicators of labor analgesia ,labor and labor under different maternal cesare-an section index .Results The two groups of pregnant women ,pregnant women ,pregnant women height weight increased the time of birth weight had not obvious difference ,it was not statistical significance (P>0 .05) .In the study group ,the age ,gestational age , BMI value and the weight of newborn were higher than those in the control group ,the difference was statistically significant (P<0 .05) .Two groups of pregnant women in the presence of placental premature rupture of fetal sex and pregnancy ,it was not statisti-cal significance (P>0 .05) ,the study group maternal use of oxytocin to strengthen the proportion of women was significantly high-er than the control group ,and the existence of labor analgesia and the proportion of natural labor wage ratio was significantly lower than the control group .The difference was statistically significant (P<0 .05) .Relative head basin of its labor maternal BMI was significantly higher than that of fetal distress and neonatal weight group and the control group ,the difference was statistically sig-nificant (P<0 .05);and three groups of maternal weight gain during pregnancy compared with giving birth weight ,it was not sta-tistically significant difference (P>0 .05) .Conclusion The term vaginal delivery ,with maternal weight ,age ,gestational age and birth weight increased ,the success rate of vaginal delivery will decline ,the reasonable control of labor when the value of BMI will help to improve the success rate of vaginal delivery in pregnant women .
