Aim: Prostaglandins have a dual action of cervical ripening and induction of uterine contraction. This study was designed to compare the effectiveness of vaginal washing just before insertion of intravaginal dinoprostone., Methods: A randomized controlled trial was conducted at the Zeynep Kamil Women and Children's Health Training and Research Hospital. One hundred and ninety-one women with singleton, term pregnancy who underwent labor induction were randomly assigned to two groups: Group 1 consisted of 95 pregnant women with vaginal washing before intravaginal dinoprostone (Propess system for slow release system of 10 mg of dinoprostone) insertion (study group), and 96 pregnant women constituted the control group who did not undergo vaginal washing before intravaginal dinoprostone insertion. A parallel randomized controlled trial was conducted with an allocation ratio of 1:1 to compare the effectiveness of vaginal washing before intravaginal dinoprostone insertion., Results: The groups had similar mean age, body mass index, gestational age, gravidity, parity and Bishop score before agent insertion (P > 0.05). Duration of dinoprostone kept intravaginally, duration from the beginning of dinoprostone insert vaginally to the active phase of labor and duration from the time of intravaginal dinoprostone insertion to delivery were significantly longer in the control group (P < 0.05). Uterine hyperstimulation rate was significantly higher in study group compared to control group (P < 0.05). Meconium passage, fetal infection and neonatal intensive care unit admission were significantly higher in the control group (P < 0.05)., Conclusion: Vaginal washing before intravaginal dinoprostone insertion may increase Prostaglandin E2 bioavailability as we found shorter duration and better outcome of labor induction in the present study., (© 2018 Japan Society of Obstetrics and Gynecology.)

Objective: We compared the safety and effectiveness of oxytocin, dinoprostone and misoprostol for cervical priming., Study Design: A total of 218 patients were enrolled to receive between one and three treatments according to physicians' options. The end points were: (1) vaginal delivery or Bishop score ≥ 8 at the end of 12 h, (2) vaginal delivery by 12 h or difference ≥ 4 between the initial and 12th hour Bishop scores. Statistical analyses were performed with ANOVA, Krustal Wallis, Scheffe, χ², Fisher, Advanced χ², and Kolmogorov-Smirnov tests. Tukey's HSD was used as a post hoc test., Results: Misoprostol showed statistical significance for the rate of vaginal delivery <12 h, ≥ 8 Bishop score at the end of 12 h, and cervical change of ≥ 4 Bishop scores within 12 h (p = 0.013)., Conclusions: Comparison between cases Bishop score <4 showed that misoprostol is more effective than dinoprostone and oxytocin. Considering Bishop score = 0 cases we calculated no statistical significance.
