Prognostic effect of intrauterine pregnancy induced by different methods of cervical ripening / 中国基层医药

ABSTRACT

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, the total effective rate of cervical ripening was 95.0%, which was higher than 66.2% of the control group (Z=-5.716, P<0.05). The duration of labor in the observation group was (12.6±4.5)h, which was significantly shorter than (21.7±7.8)h in the control group (t=9.039, P<0.05). The total labor, postpartum hemorrhage volume had no statistically significant differences between the two groups (t=2.298, 1.102, all 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). There were no statistically significant difference between the two groups in neonatal birth weight and postnatal 1min and 5min Apgar scores (all 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.
