Clinical effects of Cook® cervical ripening balloon on promoting cervical dilation for early termination of pregnancy in high-risk parturients.

Abstract

We aimed to evaluate the clinical effects of oxytocin, misopros-tol, controlled-release dinoprostone suppository, and Cook® cervical ripening balloon on early termination of pregnancy in high-risk parturients. Four hun-dred high-risk full-term parturients not in labor who were unsuitable for await-ing delivery and treated from May 2018 to July 2020 were divided into groups I-IV with a random number table (n=100). They received labor induction by oxytocin, misoprostol, controlled-release dinoprostone suppository, and Cook® cervical ripening balloon, respectively. The general data, cervical ripening ef-fect, delivery outcome, delivery time, adverse reactions, and neonatal condi-tions were compared. The time from the beginning of labor induction to labor and duration of the first, third, and total stages of labor were shorter in group II-IV than in group I (p<0.05). The incidence rates of excessive uterine contrac-tion in groups II and III were higher than those of groups I and IV, and the inci-dence rates of fetal distress in groups I-III exceeded that of group IV (p<0.05). The neonatal Apgar scores of groups III and IV were higher than those of groups I and II (p<0.05). Cook® cervical ripening can promote cervical maturation and shorten the labor induction time and stage of labor.
