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.
