Intracervical Foley catheter balloon vs. prostaglandin in preinduction cervical ripening.

OBJECTIVES: The aim of this study is to compare the effectiveness of the intracervical Foley balloon catheter and 3 mg prostaglandin E(2) tablet(s) in preinduction cervical ripening. METHODS: Ninety women referred to the maternity clinic for induction of labor with a Bishop score of less than or equal to 5 were randomized to receive an intracervical Foley catheter or prostaglandin E(2) tablets. The primary measured outcome was ripening of the cervix as measured with the Bishop score. RESULTS: There were no differences in mean Bishop scores between the prostaglandin and the Foley catheter groups. Bishop scores (mean+/-S.D.) after ripening were 6.6+/-0.80 and 6.7+/-0.86 for the Foley catheter and prostaglandin groups, respectively (P=0.54). The Foley catheter group showed a statistically shorter time to ripening compared with the prostaglandin group (3.4+/-2.1 and 6.5+/-3.2 h, respectively (P=0.001). There was no statistically significant difference in induction time (4.8+/-1.8 h and 5.3+/-2.4 h, respectively (P=0.36). CONCLUSIONS: There are no differences in preinduction cervical ripening efficacy between prostaglandin E(2) and the Foley catheter, but the Foley catheter has the advantage of ripening an unfavorable cervix in a shorter time.     

Foley尿管水囊联合缩宫素用于足月妊娠促宫颈成熟的有效性、安全性和对产程的影响#br#

Objective?To explore the application effectiveness and safety of Foley catheter water bag combined with oxytocin in promoting cervical ripening and its influences on stages of labor in full-term pregnancy. Methods?A total of 102 full-term pregnant women with induced labor indications in Obstetrics Department of our hospital were enrolled between June 2017 and January 2021. According to different treatment methods by their willingness, they were divided into control group (51 cases, oxytocin) and combination group (51 cases, Foley balloon combined with oxytocin). Before induced labor and after intervention, cervical ripening effects in both groups were observed. The effect of cervical ripening before labor induction and after intervention in the two groups was observed, and the labor process and maternal and infant outcomes were compared between the two groups. Results?After intervention, Bishop scores were significantly higher than those before induced labor in both groups, which were significantly higher in combination group than control group (P<0.05). The first stage of labor and total stage of labor in combination group were significantly shorter than those in control group (P<0.05). The successful rate of labor induction and vaginal delivery in the combined group were higher than those in the control group, and the rates of postpartum hemorrhage and soft birth canal tearing were lower than those in the control group (P<0.05). The neonatal Apgar score in combination group was higher than that in control group (P<0.05). Conclusion?Foley catheter water bag combined with oxytocin can effectively and safely promote cervical ripening and shorten stages of labor in full-term pregnant women.     

可控释地诺前列酮栓与米索前列醇及Foley尿管用于足月妊娠促宫颈成熟及引产的效果及安全性比较

Objective?To explore the effects and safety of controlled-release dinoprostone suppositories, misoprostol and Foley catheters for full-term pregnancy in promoting cervical ripening and induce labor. Methods?86 full-term pregnant primiparas with cervical Bishop score<6 and indications for labor induction were prospectively selected and admitted between May 2020 and August 2021. They were divided into 3 groups according to the internal sampling method, 29 cases as group A were treated with controlled-release dinoprostone suppositories, 27 cases as group B were treated with misoprostol, and 30 cases as group C were treated with Foley catheters. The treatment effects and safety of the three groups were compared. Results?The time from induction to labor and the time from labor induction to delivery in group A and C were shorter than those in group B (P＜0.05), and the success rate of induction was higher than that in group B (P＜0.05). The cervical Bishop scores after administration of 4 h, 12 h and 24 h were all higher than group B (P＜0.05). Conclusion?Compared with misoprostol, the controlled-release dinoprostone suppository and Foley catheter are more suitable for full-term pregnancy induction, which can promote cervical ripening and increase the success rate of labor induction.     

A randomized trial comparing a 30-mL and an 80-mL Foley catheter balloon for preinduction cervical ripening

OBJECTIVES: The purpose of this study was to compare the efficacy of cervical ripening with 2 Foley catheter balloon volumes. STUDY DESIGN: Pregnant women admitted for induction of labor with a term singleton gestation were randomly assigned for cervical ripening by a balloon inflated with 30 mL or 80 mL of sterile saline. RESULTS: Two hundred and three women were included in the analysis. Ripening of the cervix with the larger balloon volume was associated with a significantly higher rate of post-ripening dilatation of 3 cm or more (76.0% vs 52.4%, P < .001). In primiparous women, the larger balloon volume resulted in a significantly higher rate of deliveries by 24 hours (71.4% vs 49%, P < .05), and a significantly less requirement of augmentation with oxytocin (69.3% vs 90.4%, P < .05). CONCLUSION: Ripening of the unfavorable cervix in primiparous women with a Foley catheter balloon inflated with 80 mL provided effective more dilatation, faster labor, and decreased need for oxytocin than with a balloon inflated with 30 mL of sterile saline.     

Labor induction in women with an unfavorable Bishop score: randomized controlled trial of intrauterine Foley catheter with concurrent oxytocin infusion versus Foley catheter with extra-amniotic saline infusion with concurrent oxytocin infusion

OBJECTIVES: This study was undertaken to determine whether the addition of extra-amniotic saline infusion improves the efficacy of the Foley catheter in women undergoing cervical ripening and induction of labor with an unfavorable cervical examination. STUDY DESIGN: One hundred consenting women with a Bishop score less than 5 with singleton gestation, intact membranes, vertex presentation, who required induction of labor were randomly assigned to 2 groups: Foley alone (Foley, n=49) or to the Foley catheter with extra-amniotic saline infusion (EASI, 30 mL of NS per hour infused through the distal port of the Foley, n=51). All women received concurrent dilute oxytocin infusion per protocol. The primary analysis was intent to treat. Nonparametric tests were used as indicated. RESULTS: At randomization, the groups were well balanced for potential confounders including: parity, gestational age, prior cesarean delivery, preeclampsia, mean dilation, effacement, and Bishop score. There were no differences between the groups for time to delivery (Foley 17.7 +/- 10.5 hours vs EASI 17.4 +/- 11.7 hours, P=.9), the proportion of women delivered before 24 hours (Foley 41/49 [84%] vs EASI 39/51 [77%], P=.37) or cesarean rates (Foley 9/49 [17.7%] vs EASI 9/51 [18.4%], P=.92). There were also no differences in complications, including chorioamnionitis, endometritis, and neonatal morbidity. CONCLUSION: EASI does not increase the efficacy of cervical ripening and induction of labor with a Foley catheter and concurrent oxytocin infusion.     

Unsucessful labour induction in women with unfavourable cervical scores: predictors and management

BACKGROUND: Misoprostol fails to induce labour in 5-20% of women at term. AIM: To analyse possible predictors of unsuccessful induction with 50 microg vaginal misoprostol and effectiveness and the safety of intracervical Foley catheter application in induction failures. METHODS: An observational study was conducted on 1030 women with singleton, live fetuses, vertex presentation, > 34 weeks of gestation and Bishop score < 5. Induction of labour with 50 microg vaginal misoprostol repeated every 6 h was attempted. Women without regular uterine contractions and cervical changes at the end of 24 h were considered to be unsuccessful, and a transcervical Foley balloon catheter was placed and inflated with 50 mL saline. Possible predictors of induction failures were analysed via logistic regression analysis. Neonatal outcomes and vaginal delivery achieved after Foley catheter were also determined. RESULTS: Induction was successful in 918 cases (89.1%) and Foley catheter was placed in 112 (10.8%) women. Increasing gestational age in weeks (odds ratio [OR] 0.77, 95% confidence interval [CI] 0.68-0.88) and increasing Bishop score (OR 0.73, 95% CI 0.60-0.90) decreased the risk of failed induction. Failure rates were 16% (27/169) in post-term nulliparous women with Bishop score 相似文献   

Comparison of extraamniotic Foley catheter and intracervical prostaglandin E gel for preinduction cervical ripening

BACKGROUND: The success of induced labor depends on the degree of ripening of cervix. Pharmacological preparations are in widespread use for cervical ripening but are not free from side-effects and complications. Mechanical methods, i.e. the use of Foley catheter balloon, though effective have not gained much popularity because of the fear of infection. Therefore, this study has been conducted to prove the efficacy and safety of extraamniotic Foley catheter balloon and to compare it with intracervical prostaglandin E2 (PGE2) gel. METHODS: The randomized prospective study was conducted in the Department of Obstetrics and Gynecology and Medical Microbiology of Nehru Hospital. Hundred women attending the labor ward for induction of labor were divided into two groups: Group A--Foley catheter, Group B--PGE2 gel. Cervical swabs before and after the insertion of ripening agents were taken for culture studies. Placental membranes were also sent for culture. Labor outcome, side-effects, and complications were compared in both the groups. The statistical methods used were Student's compared t-test, Chi-square test, and Wilcoxon-Mann-Whitney test. RESULTS: Foley catheter proved to be a very effective preinduction ripening agent for unfavorable cervix compared with PGE2 gel, as is evident by the mean Bishop score at 12 h (P<0.001). Preparation delivery interval was significantly shorter (P<0.05) in women who underwent cervical ripening with Foley catheter balloon than with the PGE2 gel. No clinical evidence of chorioamnionitis was present in both the groups. CONCLUSION: This study concludes that extraamniotic Foley catheter balloon is an effective, safe, simple, low-cost, reversible, non-pharmacological mechanical method of preinduction cervical ripening.     

A randomized comparison of transcervical Foley catheter to intravaginal misoprostol for preinduction cervical ripening

OBJECTIVE: To compare the efficacy of intravaginal misoprostol tablets with transcervical Foley catheter for preinduction cervical ripening. METHODS: Pregnant women who presented for induction of labor with unfavorable cervices (Bishop score less than 6) were assigned randomly to intravaginal misoprostol (50 microg tablet every 4 hours for a maximum of six doses) or 30-mL Foley catheter placed transcervically with maintenance of traction. RESULTS: Among 111 women, 53 were allocated to misoprostol and 58 to Foley bulb. Contractile abnormalities were more frequent in the misoprostol group (20.4%) than the Foley group (0%) (P <.001). No statistically significant differences were noted between groups in change in Bishop score, preinduction cervical ripening times, and total induction times. There were no statistically significant differences in mode of delivery or adverse neonatal outcomes. Uterine rupture occurred in one woman with two previous cesarean deliveries in the misoprostol group. CONCLUSION: Intravaginal misoprostol and transcervical Foley catheter are equivalent for cervical ripening. Uterine contractile abnormalities and meconium passage are more common with misoprostol.
