Abstract

Objective: To compare the efficacy and safety of the trans-cervical double balloon catheter with and without extra-amniotic saline infusion (EASI) for cervical ripening. Methods: This is a secondary analysis of a prospective randomized study conducted between November 2007 and January 2011 evaluating different ripening methods. Women presenting for labor induction were assigned to receive the double balloon catheter with (study group) or without EASI (control group). Outcomes included time from device insertion to delivery, cesarean section rates, and adverse events. Results: One hundred and sixty women completed the study. Cesarean section rate (8.3% in study group, versus 20% in controls p = 0.07) and ripening success were comparable between the groups. Catheter insertion to delivery interval was significantly shorter and spontaneous catheter expulsion rate was significantly higher in the study group (14:19 hours versus 20:45 hours, p < 0.001, and 68.5% versus 51%, p = 0.04, respectively). Hospitalization length was significantly shorter in the study arm. There were no differences in other outcomes evaluated. A multivariable analysis found the EASI to be an independent predictor of a shorter insertion to delivery interval. Conclusions: The addition of EASI to the double balloon catheter for cervical ripening results in a shorter labor induction process without compromising its safety.
