Abstract：Objective To explore the application effect of COOK cervical balloon in induced labor of pregnant women and its influence on pregnancy outcome. Methods A total of 98 full-term pregnant women who were expected to give birth in our hospital from June 2018 to January 2020 were selected as the research objects, they were divided into two groups by random number table method, with 49 cases in each group. The control group was given Oxytocin to induce labor, and the observation group was given COOK cervical balloon in induced labor. The cervical maturity, newborn conditions and maternal delivery were compared between two groups,and the occurrence of maternal adverse reactions was counted. Results Before intervention, there was no significant difference in the cervical Bishop score of pregnant women of the two groups (P＞0.05); after intervention, the cervical Bishop scores of pregnant women of two groups were higher than those in this group before intervention, and the observation group was higher than that in the control group, the differences were statistically significant (P＜0.05). The total labor time in the observation group was shorter than that in the control group, the natural delivery rate in the observation group was higher than that in the control group, the cesarean section rate and the total incidence of adverse reactions in the observation group were lower than those in the control group, the differences were statistically significant (P＜0.05). There were no significant differences in the neonatal Apgar score, neonatal asphyxia rate and postpartum bleeding volume between the two groups (P＞0.05). Conclusion The use of COOK cervical balloon in induced labor of pregnant women can increase cervical Bishop score, promote cervical maturity, improve pregnancy outcome, reduce cesarean section rate, and shorten the stages of labor, which is worthy of clinical application and promotion.
