Abstract

We aimed to evaluate the clinical effects of oxytocin, misoprostol, controlled-release dinoprostone suppository, and Cook® cervical ripening balloon on early termination of pregnancy in high-risk parturients. Four hundred high-risk full-term parturients not in labor who were unsuitable for awaiting 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 effect, delivery outcome, delivery time, adverse reactions, and neonatal conditions 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 contraction in groups II and III were higher than those of groups I and IV, and the incidence 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.
