Objective To explore the influence of epidural analgesia(EA) on the effect of term labor induction of primiparous women by COOK double ballon

and evaluate the maternal and neonatal outcomes. Methods The data of 91 primiparous women who received COOK double ballon for induction of term labor were retrospectively analyzed.The cases received EA were named as group EA+COOK and others were named as group COOK.The mode of delivery was observed and compared between the two groups.The duration of labor

maternal complications

infant complications and medication of antibiotic of the patients delivered vaginally were observed and compared between the two groups. Results The vaginal delivery rate was 91.67% in the group EA+COOK and 50.91% in the group COOK.The first stage of labor and the second stage of labor in group EA+COOK were longer than those in group COOK

the vaginal delivery rate within 24 hours after balloon delivery and the vaginal delivery rate within 12 hours after rupture of membrance in group EA+COOK were lower than those in group COOK

and the rate of prenatal fever

the usage rate of antibiotics and the amount of postpartum hemorrhage in group EA+COOK were significantly higher than those in group COOK

the differences were significant(P<0.05).There was no statistical difference in the incidence of neonatal asphyxia between the two groups. Conclusion EA can promote the effectiveness of COOK double ballon for induction of term labor of primiparous women

whereas

more attention and interventions were needed because EA will prolong the labor stage and result in some adverse events.
