Clinical Study On The Maternal And Neonatal Safety With Transcutaneous Electrical Nerve Stimulation Or Epidural Analgesia In Labor

Objectives:Investigating the effects of transcutaneous electrical nerve stimulation and epidural analgesia among nulliparous women on delivery method,duration of labor,the use rate of oxytocin,the rate of episiotomy,incidence of acute fetal distress,Apgar score,postpartum hemorrhage and amniotic fluid properties,the study aimed to explore the safety of labor analgesia in clinical applications.Methods:In this study,415 nulliparous women meeting the inclusion and exclusion criteria for hospitalization in our department were selected and divided into transcutaneous electrical nerve stimulation(TENS)group,epidural analgesia(PCEA)group and control group.Record the message of delivery method,duration of labor(latent phase,active phase,second stage of labor,third stage of labor),the use rate of oxytocin in the stage of labor,the rate of episiotomy,incidence of acute fetal distress,Apgar score,rate of hospitalization in pediatrics,the total amount of bleeding for 2 hours postpartum,postpartum hemorrhage,amniotic fluid properties,other maternal and neonatal complications.To evaluate two modes of labor analgesia on maternal and neonatal safety.Results:1.There was no significant difference in age,gestational age,pregnancy time,body mass index and newborn weight among the three groups of nulliparous women(P>0.05).2.The cesarean section rate and the non-medical indication cesarean rate were lower in two analgesia group than control group,and the difference was statistically significant(P<0.05);the rate of cesarean section was significantly lower in the TENS-group(15.90%)than control group(29.07%)(P<0.05);the rate of cesarean in the PCEA-group(17.24%)was lower than control group(29.07%),the difference was statistically significant(P<0.05);the non-medical indication cesarean rate in the TENS-group(4.55%)was significantly lower than the control group(16.93%),the difference was statistically significant(P <0.05);non-medical indication cesareanrate in the PCEA-group(3.45%)was significantly lower than the control group(16.93%),the difference was statistically significant(P<0.01);There was no significant difference in the cesarean rate and the non-medical indication cesarean rate between the TENS-group and PCEA-group(P>0.05).3.The average amount of bleeding for 2 hours postpartum in the TENS-group,PCEA-group and control group was(404.20ml±188.07),(478.02ml±237.78)and(497.86 ml ± 248.87)respectively.The comparison between tow groups shows the bleeding volume at 2h postpartum in the TENS-group was significantly less than control group(P<0.05);The average blood loss at 2h postpartum in the PCEA-group was also less than control group,with no statistically significant difference(P>0.05).There was no significant difference in bleeding volume at 2h postpartum between the TENS-group and the PCEA-group(P>0.05).The incidence of postpartum hemorrhage in the TENS-group,PCEA-group and control group was2.27%,3.45% and 8.63% respectively,and the difference was not statistically significant(P>0.05).4.there was no significant difference in the duration of the stage of labor,the rate of episiotomy,the use rate of oxytocin and amniotic fluid properties amniotic fluid properties between the three groups(P>0.05).5.The incidence of acute fetal distress,Apgar score and neonatal transfer pediatric rate were not statistically significant(P>0.05).Conclusions: Transcutaneous electrical nerve stimulation and Epidural analgesia in labor can reduce the cesarean section rate;Transcutaneous electrical nerve stimulation of labor analgesia reduces the amount of bleeding for 2 hours postpartum;Two methods of labor analgesia have no short-term adverse effects on maternal and neonatal and can be used for clinical.
