Objective To investigate and compare the application effect of artificial rupture of membrane and COOK double-balloon induction of labor in full-term pregnant women.Methods A total of 100 full-term pregnant women admitted to the Department of Obstetrics of Huiyang Sanhe Hospital in Huizhou City,Guangdong Province from April 2021 to February 2022 were selected as the research objects.They were divided into observation group (50 cases)and control group(50 cases) by random number table method.The control group was induced by artificial rupture of membrane,and the observation group was induced by COOK double-balloon on the basis of the control group.The stages of labor and cervical maturation before and after intervention were compared between the two groups.The outcomes of delivery and postpartum hemorrhage were compared between the two groups.Neonatal Apgar scores were compared between the two groups.Results The first stage of labor and the total stage of labor in the observation group were shorter than those in the control group,and the differences were statistically significant (P＜0.05).The cervical maturity score (Bishop score)of the observation group after intervention was higher than that of the control group,and the difference was statistically significant (P＜0.05).There was no significant difference in the overall incidence of adverse delivery outcomes between the two groups (P＞0.05).The blood loss at 1 and 2 hours after delivery in the observation group was less than that in the control group,and the difference was statistically significant (P＜0.05).The Apgar scores at 1 and 5 min postnatal in the observation group were higher than those in the control group,and the differences were statistically significant (P＜0.05).Conclusion In the induction of labor of full-term pregnant women,the application of COOK double-balloon can shorten the total labor process,improve the degree of cervical maturation and the delivery outcome,reduce the occurrence of adverse outcomes,further control the amount of postpartum blood loss,and improve the Apgar score of newborns,which is worthy of research and reference.
