Objective: To compare the significance of Bishop scores in neonates delivered via single versus double balloon induction of labor through a comprehensive metaanalysis.We conducted a meta-analysis of randomized controlled trials comparing single-balloon and double-balloon catheters for labor induction. Studies were identified through searches in MEDLINE, EMBASE, PubMed, and the Cochrane Library. The primary outcome was the Bishop score, while secondary outcomes included mode of delivery, complications, catheter-to-delivery interval, and Apgar score at 5 minutes.Our meta-analysis included six randomized trials with 996 women undergoing labor induction. We found a significant difference in Bishop scores favoring single balloon catheter induction. Specifically, neonates delivered via single balloon catheter had higher Bishop score compared to those delivered via double balloon catheter. This finding highlights the clinical significance of Bishop scores in identifying infants who require immediate medical attention. However, we did not find significant differences in mode of delivery, complications, or Apgar scores between the two groups (P > 0.05).Single balloon catheter induction of labor is more effective in ripening the cervix, as evidenced by higher Bishop scores, suggesting it may be a preferable method for labor induction.
