Abstract: Objective To explore the value of cook cervical dilatation balloon versus misoprostol for induction of labour in full-time pregnancy hypertensive women. Methods From June 2017 to May 2018, 110 hypertensive parturient women of full-time pregnancy who plan to delivered in our hospital were randomly divided into balloon group (55 cases) and misoprostol group (55 cases) and were given cook cervical dilatation balloon and oral misoprostol respectively for induction. The delivery situation, the information of induction to vaginal birth, complication of induction and birth, newborn information and complication after induction. Results No significant difference in Rupture of membranes, first stage of labor and second stage of labor between the two group (P>0.05) and the cases of vaginal birth, effective cervix mature improving, cases of oxytocin usage and artifact rupture of membranes were significantly higher in balloon group than those in misoprostol group and time from induction to parturient in balloon group were lower than those in misoprostol group (P<0.05). The total cases of induction to vaginal birth in balloon group (74.54%) was significantly higher than that in misoprostol group (52.72%) and total time from induction to birth in balloon group was significantly lower than that in misoprostol group (P＜0.001). The total rate of complication in balloon group (43.64%) was significantly higher than that in misoprostol group (65.45%)， P=0.035. Apgar score, newborn death, cases admitted to nursery, given oxygen and complication were no significant different between two group (P>0.05). No significant difference were found in dizziness, nausea, vomit and long pain during incubation between two group (P>0.05). Conclusion For hypertensive parturient women of full-time pregnancy, comparing with oral misoprostol, cook cervical dilatation balloon can short the stage of delivery, increase success rate of induction, reduce delivery complication and has high safety.
