The aim of the present study is to compare the effectiveness and safety of oxytocin and cervical ripening balloon in women with unfavorable cervices for inducing labor.

Material and Methods:

Total of eighty pregnant women between 37-41 gestational weeks having singleton pregnancies and intact membranes with unfavorable cervix were randomized in two groups, cervical ripening balloon (n=40) and oxytocin infusion (n=40). The primary outcomes were the labor time and the route of delivery. Secondary outcomes were the effect of parity on time of labor, obstetric and perinatal outcomes.


The median time to delivery was 9,45 hours in cervical ripening balloon and 13,2 hours in oxytocin group in multiparous women. The differences were statistically significant (p<0.001). Median time until delivery was 11.48 hours at cervical ripening balloon group and 13,46 hours at oxytocin group; the differences were statistically significant (p<0.001). Cesarean delivery ratios were similar in both groups (p=0.431).


The results of the present study were promising for balloon usage especially in multiparous women. It is beneficial to support these data with wide ranged population based studies.
