Abstract To investigate the effect of cervical COOK double balloon combine with rivanol amniocentesis for induction of labor during the second trimester of pregnant women with scar uterus. Methods: 120 pregnant women during the second trimester with scar uterus were enrolled in the study from January 2016 to January 2018, and they were divided into 3 groups according to the random number table. 40 women in group A were treated by COOK double balloon combined with mifepristone, 40 women in group B were treated by COOK double balloon combined with rivanol amniocentesis, and 40 women in group C were treated by rivanol combined with mifepristone. The cervical Bishop score, blood pressure, effect of induction of labor, and bleeding volume of women were compared among the three groups. Results: The Bishop scores of women in group A or group B increased after treatment, and which was significant higher than that of women in group C (P<0.05).The effect of women in group A and group B was significant higher than that of women in group C (P<0.05), and the time of induction of labor of women in group A or group B was significant shorter than that of women in group C (P<0.05). There were no significant differences in uterine contraction time and bleeding volume among the three groups (P>0.05). There were no any women with cervical tears, uterine rupture, or profuse bleeding in the three groups. Conclusion: Cervical COOK double balloon for pregnancy induction of labor during the second trimester of patients can effectively promote cervical ripening, shorten the time of induction of labor, and have fewer complications.
