Comparison Of Maternal And Infant Outcomes Under The Management Of New And Old Labor Standards

Objective: By comparing the success rate of vaginal delivery,the rate of vaginal delivery,the rate of conversion to cesarean section,the indication of conversion to cesarean section,the way of artificial intervention,the outcome of mother and infant and the prognosis of obstetrics in the Affiliated Hospital of Hebei University of engineering,under the management of the new and old standards of different stages of labor,we can further explore whether the new standard of birth is suitable for the delivery population in China.Materials and methods: retrospective study was used to collect the clinical data of 722 pregnant women who were hospitalized in the Affiliated Hospital of Hebei University of engineering from April 2013 to April 2014 and from April 2018 to April 2019 and who underwent vaginal trial delivery,excluding those who were premature,multiple,fetal malformation,stillbirth and pregnant women with serious internal and external diseases.364 pregnant women from April 2013 to April 2014 were divided into the control group and 358 pregnant women from April 2018 to April 2019 as the observation group.Friedman’s labor process standard was used in the treatment of the control group,and the treatment of the observation group was carried out in accordance with the expert consensus on new labor process standard and treatment(2014).Statistical methods: The data of this study were processed by SPSS v25.0 software package(IBM,Armonk,NY).The measurement data satisfying the normal distribution is represented by t-test and data is represented by x ± s;the measurement data not satisfying the normal distribution is represented by rank sum test and data is represented by median(interquartile spacing).Chi square test is used for variable analysis of counting data.When the expected frequency is less than 5 and the total number of cases is less than 40,Fisher’s exact probability method is used,and the number and percentage of data cases are used to represent.If P<0.05,it shows that there are differences between the data,which has statistical significance.Results:1.General information comparison In the comparison of the general data of the observation group and the control group,there were no statistically significant differences in maternal age,gestational week,gestation period,parity,BMI,and neonatal weight,and the clinical data were comparable.2.Comparison of delivery methods under the new / traditional labor standards The rate of vaginal helpless delivery and vaginal delivery rate in the control group was significantly lower than those in the observation group,meanwhile,the rate of transit to cesarean section was significantly lower than that in the control group.The data difference between the groups was statistically significant(P<0.05);the vaginal delivery rate in the control group was lower than that in the observation group,but after statistical comparison,the data difference between the groups was not significant(P> 0.05).3.Comparison of manual intervention methods under the standard management of new and old labor processes In the observation group,the rate of labor disruption with artificial rupture and oxytocin was significantly lower than that in the control group,and the data difference between the groups was statistically significant(P<0.05);the epidural block rate in the observation group was significantly higher than that in the control group.After statistical comparison,there was a significant difference(P<0.05).4.Comparison of production time limit under the new / old production standard management The first and second labor time in the control group were significantly lower than those in the observation group,and there was significant difference through statistical comparison(P<0.05).5.Comparison of maternal and infant outcomes under the new / old birth standard management The observation group’s postpartum hemorrhage rate,perineum III / IV degree laceration rate,neonatal asphyxia rate,and large child rate were slightly higher than those of the control group,but the difference was not significant after statistical comparison(P>0.05);Compared with the control group,the rate was obviously reduced,and the difference was statistically significant(P<0.05).6.Comparison of indications for transitional cesarean section in standard management of new and old labor processes The rate of transition to cesarean section in the control group was slightly lower than that in the observation group due to intrauterine distress,relative pelvic disproportion,abnormal fetal position,and placental abruption.The rate of transition to cesarean section was slightly higher due to social factors and umbilical cord prolapse It was lower than the control group,but after statistical comparison,the data difference between the groups was not significant(P>0.05).Conclusions:1.Using the new labor process standard to deal with the labor process,the vaginal trial is sufficient,the cesarean section rate is decreased,the vaginal delivery rate is increased,and the natural delivery is promoted.2.Using the new labor process standard to deal with the labor process can reduce unnecessary manual intervention,actively carry out labor analgesia,reduce the pain of the parturient,and reflect the medical humanistic care.3.Using the new labor process standard to deal with the labor process did not increase the occurrence of adverse outcomes of mothers and infants,but reduced the rate of lateral perineum incision,which was conducive to the prognosis of the parturient.4.The standard of new labor process accords with the characteristics of Chinese labor population and should be popularized in an all-round way.
