Abstract Objective: To observe the clinical efficacy of cervical dilatation balloon for promoting cervical ripening and induction of labor of later stage pregnant women. Methods: 200 fullterm pregnant women in Fuyang district maternity and child health care hospital from October 2016 to December 2017 were selected and were divided into control group (n=100) and study group (n=100) according to the random number table method. Women in control group were given small dose oxytocin for induced labor, and women in study group were given cervical dilatation balloon for induced labor. The cervical maturity condition of women was evaluated, and the mode of delivery, pregnancy outcomes, and the rate of perinatal complications were compared. Results: After 12h of induction, the Bishop score of women in study group (6.8±1.4 scores) was significant higher than that (5.5±1.4 scores) of women in control group (P<0.05). The total effective rate of improving cervical maturity (94.0%) of women in study group was significant higher than that (77.0%) of women in control group (P<0.05), and the rate of vaginal delivery (82.0%) in study group was significant higher than that (69.0%) of control group (P<0.05). The during of the first stage of labor, the second stage of labor and the total stage of labor of the women in study group were significant shorter than those of women in control group (P<0.05). There was no significant differeny in the incidence of perinatal complications of women between study group (9.0%) and control group (10.0%) (P<0.05). There was no any woman with adverse reactions, such as phenomena, placental abruption and cervical rupture in both groups. Conclusion: Compared with oxytocin induction of labor, cervical dilatation balloon can significantly improve cervical maturity of women with late pregnancy stage, can increase the success rate of vaginal delivery, and can shorten the time of labor, and has better safety, so it is worthy of clinical application.
