Prognostic effect of intrauterine pregnancy induced by different methods of cervical ripening

Objective To investigate the effect of different cervical ripening methods on induction of labor in term pregnancy. Methods 160 cases of labor induction of full-term pregnancy primipara were selected as the research subjecs.According to the different methods of cervical ripening, they were divided into two groups.The observation group (n=80) underwent dinoprostone suppositories induced labor, the control group (n=80) received intravenous infusion of small dose of oxytocin.The cervical Bishop score, cervical ripening effect, induction of labor, mode of delivery, neonatal outcome were observed in the two groups. Results Before treatment, the Bishop scores of the two groups had no statistically significant difference (t=0.436, P>0.05). After treatment for 24h, the Bishop score of the observation group was (8.3±2.6)points, which was higher than (5.9±2.0)points of the control group (t=6.544, P 0.05). In the observation group, 66cases (82.5%) were vaginal delivery, 14cases(17.5%) were cesarean section, those were 49cases(61.2%) and 31cases(38.8%) in the control group.The delivery mode of the observation group was significantly better than that of the control group(χ2=8.935, P 0.05). Conclusion Parturient with dinoprostone suppositories full-term pregnancy abortion can improve the cervical Bishop score and cervical ripening effect, improve the quality of delivery, it is better than oxytocin, and worthy of clinical application.
