Abstract: Objective To analyze the effect of painless epidural anesthesia in primiparas and the influence on the outcome of labor and mother and infant. Methods 400 cases of primiparas from August 2016 to September 2016 in our hospital, 200 cases of the study group were used epidural anesthesia technique, 200 cases of control group were not given any analgesic measures, the maternal pain grade distribution, uterine contraction, fetal heart rate, fetal childbirth time delivery rate, hemodynamics, planing by the time of birth process, postpartum hemorrhage, neonatal Appar score, postpartum complications were compared between the 2 groups. Results The results showed that the distribution of pain in study group was significantly better than the control group(P<0.05), two groups of maternal uterine contraction time, fetal heart rate, fetal childbirth pregnant women mean arterial pressure, heart rate and pulse oxygen saturation had no significant difference(P>0.05). 15 patients in the study group expected through natural childbirth switched to cesarean section delivery, plane palace yield was 7.5%, while 37 cases in the control group had switched to cesarean section delivery the plane section rate was 18.5%, there was significant difference between two groups(P<0.05). The first birth processof the study group(10.83±0.76)h was shorter than that in the control group(12.41±0.97)h(P<0.05), there was no statistically significant difference in the amount of postpartum hemorrhage and neonatal Appar score in the two groups(P>0.05), there was no significant difference between the 2 groups considering postpartum bleeding, urination, perineal laceration(P>0.05). Conclusion Epidural block anesthesia painless delivery technology can relieve the pain and pain in the delivery process, shorten the labor process, reduce the cesarean section rate, and have less influence on the safety of mother and baby.
