Abstract To compare the clinical effects of single balloon, double balloon, and dinoprostone suppositories for the uterine cervical maturation and induction of labor of pregnant women with full term pregnancy. Methods: A retrospective analysis was performed on 300 pregnant women with full term pregnancy who had accepted induction of labor from January 2018 to June 2019. According to the different methods of promoting cervical maturity, they were divided into 3 groups, which included 100 women experienced promoting cervical maturity by single balloon in group A, 100 women experienced promoting cervical maturity by double balloon in group B, and 100 women experienced promoting cervical maturity by dinoprostone suppositories in group C. The cervical Bishop scores, the time from induction to labor, total labor time, postpartum hemorrhage volume, and delivery methods of women were compared among the three groups. Results: There were no significant different in the effective rate of cervical ripening (92%, 89% vs. 91%) among the three groups (P>0.05). The cesarean section rate of women in group C (28%) was significant higher than that (9%) of women in group A and that (11%) of women in group B (P＜0.05). The value added of cervical Bishop score of women in group A was 4.0±1.4 points, which had no significant different from that (3.5±1.6 points) of women in group B and that (3.6±1.6 points) of women in group C (P>0.05). The time from drug used to delivery and the total duration of labor of women in group C were 13.9± 10.8h and 7.1±2.6h, which were significant shorter than those in group A and B (P＜0.05). There was no significant different in postpartum blood loss of women among group A (335±91ml), group B (358±100ml) and group C (348±89ml) (P>0.05). There was no significant difference in neonatal birth weight among group A (3476±331g), group B (3482±296g) and group C (3483±296g) (P>0.05). Conclusion: There is no significant difference in the effect of promoting cervical maturation of the three induction of labor methods. The time from induction of labor to labor and the total labor time by dinoprostone suppositories are shorter than those by single or double balloon, but the cesarean rate of women after dinoprostone suppositories used is higher. So it is safer to promote cervical maturity by single or double balloon if no different effect of induction of labor.
