Effect Of Labor Analgesia On Bleeding During Cesarean Section

PurposeTo investigate the effect of epidural analgesia on hemorrhage during cesarean section during trial delivery failure.MethodsA single live birth of a healthy primiparous woman who gave birth in the obstetrics department of the Bengbu Third People's Hospital from September 2017 to September2019 was selected.After screening according to the inclusion and exclusion criteria,a total of 683 primiparas met.Of these,384 primiparas who volunteered for childbirth analgesia were the observation group,and 299 primiparous women who did not implement any analgesic measures were the control group.On the basis of no abnormalities in ECG monitoring and fetal heart monitoring,women in the observation group were given epidural analgesia when the uterine opening was 3 cm,0.08%ropivacaine 150 ml + low-dose sufentanil 40 ug combined application,maintenance amount 6 ~ 8ml / h,according to the degree of pain,the maternal can control the administration until the medicine is stopped after delivery.Throughout the process of analgesic delivery,the midwife closely monitors the situation of the mother and the fetus,and the anesthesiologist visits regularly to deal with abnormal conditions in the process of analgesia in time.The control group was treated according to the routine procedure of vaginal delivery.The rates of oxytocin use,cesarean section rate,indications for cesarean section,and blood loss during cesarean section were recorded in the two groups.ResultsThe incidence of cesarean section in the observation group was lower than that in the control group,and the difference was statistically significant(P <0.05).The oxytocin use rate was higher than that of the control group,and the difference was statistically significant(P <0.05).The volume of bleeding during cesarean section in the observation group was higher than that in the control group,and the difference was statistically significant(P <0.05).The mothers in the two groups switched to cesareansection due to abnormal fetal orientation,active stagnation,and fetal distress.The observation group had a higher incidence of abnormal fetal orientation than the control group,and the differences were statistically significant(P <0.05).Among the indications of abnormal fetal orientation,the incidence of anterior occipital fetal position in the observation group was lower than that in the control group,and the difference was statistically significant(P <0.05).Conclusion:1.Labor analgesia will increase the possibility of maternal uterine contraction weakness,leading to increased oxytocin use.2.Failure of childbirth analgesia trial delivery failed to transfer to cesarean section,increased bleeding during cesarean section.3.For pregnant women who fail to give birth to analgesia and try to deliver to cesarean section,the main reason for the increase in intraoperative bleeding is due to weakness of contractions.Anesthetics affect the pelvic floor tissue,increase the abnormal fetal position and the occurrence of active stagnation,and reflex causes contraction fatigue.For women undergoing labor analgesia,when trial delivery fails and they are transferred to cesarean section,care should be taken to prevent the increase in bleeding caused by uterine insufficiency and improve measures in advance.
