Background: Induction of labor (IOL) is an artificial initiation of labor before its spontaneous onset for the purpose of delivery of the fetoplacental unit. Many factors are associated with its success in postdatism. Objective: To compare the induction delivery intervals using transcervical Foley catheter plus oxytocin and vaginal misoprostol, and to identify the factors associated with successful induction among postdate singleton multiparae. Materials and Methods: The study was a prospective randomized controlled trial of singleton multiparous pregnant women. They were randomized into two groups, one group for intravaginal misoprostol and the other group for transcervical Foley catheter insertion as a method of cervical ripening and IOL. The data were analyzed using SPSS version 17 computer software (SPSS Inc., IL, Chicago, USA). Comparisons of categorical variables were done using Chi-squared test, with P < 0.05 considered as significant. Student's t-test was used for continuous variables. Results: The incidence of postdatism was found to be 136 (13.1%). The mean induction delivery time interval was shorter in the misoprostol group 70 (5.54 ± 1.8 h) than in the Foley catheter oxytocin infusion group 66 (6.65 ± 1.7 h) (P = 0.035). There was, however, no statistically significant difference in the maternal and neonatal outcomes when these two agents were used for cervical ripening and IOL. Higher parity and higher Bishop's score were the factors found to be associated with high success rate of IOL (P < 0.001). Conclusion: Vaginal misoprostol resulted in shorter induction delivery time interval as compared to transcervical Foley catheter. High parity and high Bishop's scores were the factors found to be associated with the success of IOL.
