There were significantly less women with uterine hyperstimulation in the double balloon catheter group (2 vs 24, p=<0.0001) compared to the prostaglandin group. There were no women with uterine hyperstimulation and non-reassuring fetal status in the double balloon group while there were 5 women with uterine hyperstimulation and fetal distress in the prostaglandin group. Use of pain relief was significantly less in the double balloon catheter group (p=0.009). There were no significant differences in both groups in mode and time to delivery, although significant less time was needed to achieve os dilation more than 4cm in the double balloon catheter group (p=<0.0001).
