Abstract
Objective: To compare the efficacy of simultaneous and sequential administration of oxytocin and intrauterine balloons in labor induction.
Methods: The databases of Cochrane Library, Web of Science, PubMed, ClinicalTrials.gov, and Embase were thoroughly searched from their inception to November 2023. Randomized controlled trials (RCTs) investigating the simultaneous and sequential use of oxytocin and intrauterine balloons for labor induction in pregnancy were included. The meta-analysis was performed using RevMan 5.3 statistical software. Heterogeneity among the selected studies was evaluated using the I2 statistic. Dichotomous outcomes were estimated using relative risk (RR) with corresponding 95% confidence intervals (CI), while continuous outcomes were measured as the mean difference (MD).
Results: A total of eight studies, involving a total of 1,315 nulliparous and multiparous women with an unfavorable cervix, were included in the systematic review. Moreover, a subgroup analysis was conducted, separately evaluating nulliparous and multiparous women. Compared with the sequential groups, simultaneous use of oxytocin and intrauterine balloons resulted in a significantly higher rate of delivery within 24h in nulliparas (RR = 1.30, 95%CI:1.04, 1.63, p = 0.02), a higher rate of vaginal delivery within 24h in multiparas (RR = 1.32, 95%CI:1.15,1.51, p < 0.00001), a superior rate of delivery within 12h and a shorter time to delivery in both nulliparas and multiparas. No statistically significant differences were observed in cesarean delivery and maternal and neonatal adverse outcomes between the sequential and simultaneous groups.
Conclusions: These findings provide support for the simultaneous use of intrauterine balloons and oxytocin during labor induction in nulliparous women. Additionally, this approach may also prove beneficial for multiparas.
