Abstract

INTRODUCTION:

The purpose of this study was to compare the effectiveness of cervical ripening with transcervical double balloon catheter alone versus transcervical double balloon catheter with concurrent oxytocin in women undergoing induction of labor at term.

METHODS:

This retrospective cohort study included 321 women with singleton pregnancies who underwent induction of labor with cervical ripening using a transcervical double balloon catheter between January 2012 and January 2014. Women receiving a transcervical double balloon catheter with concurrent oxytocin administration (oxytocin group) were compared to women undergoing cervical ripening with transcervical double balloon catheter alone (control group). Labor was managed according to routine obstetric protocols. We compared the time from insertion of the transcervical double balloon catheter to delivery for both groups.

RESULTS:

There were 205 women in the control group and 116 women in the oxytocin group. There was no significant difference in maternal demographics between the two groups. The median time from transcervical double balloon catheter placement to delivery in the oxytocin group was 12 hours and was 17.04 hours in the control group. The median difference in time from induction to delivery was 5.04 hours (95% CI 2.54–7.54; P<.001). In addition, the control group had a significantly higher rate of chorioamnionitis (4.4% vs 0%; P=.029) and postpartum hemorrhage (9.8% vs 2.6%; P=.022) than the oxytocin group.

CONCLUSION:

Concurrent oxytocin administration with transcervical double balloon catheter cervical ripening shortens time to delivery by 5.04 hours. A prospective study on the use of oxytocin in conjunction with double balloon catheter is warranted to confirm these findings.
