INDUCTION OF LABOR

Labor can be induced through a myriad of ways. The aim of this study was to compare the effectiveness of theintracervical Foley balloon catheter and intra vaginal 3 mg prostaglandin E2 tablet(s) in preinduction cervical ripening at term. Methods:Prospective analytic study of a cohort of 280 women selected through non probability sampling admitted in Obstetrics units, in two privatehospitals one at Rawalpindi and the other at Mirpur (Azad Kashmir), from January 2009 to March 2010. All women were randomized to receivean intracervical Foley catheter or prostaglandin E2 tablets. The primary measured outcome was ripening of the cervix as measured with theBishop score. Results: There were no differences in mean Bishop Scores between the prostaglandin and the Foley catheter groups. Bishopscores (mean ± S.D.) after ripening were 6.6±0.81 and 6.7±0.86 for the Foley catheter and prostaglandin groups, respectively (P=0.54). Theprostaglandin group showed a statistically shorter induction to delivery time compared with the Foley catheter (16.5±2.2 and 20.51±3.89 h,respectively (P<0.01). Both the groups showed no statistically significant difference between the occurrences of spontaneous vaginal delivery.Labor was established in 72% cases of cervical Foley group. On the other hand induction occurred in 76% cases in prostaglandin group. Therewas no statistical difference between the need of oxytocin infusion for labor augmentation between the two groups and fetal distress was equallyfrequent in both the groups. Conclusions: Foley catheter was as effective as Prostaglandin E-2 at term for induction of labor with additionaladvantage of being cheaper, readily available and had no systemic side effects.
