Abstract

The use of a Foley catheter is one of the oldest known methods of labor induction. Therefore, protocols using different volumes of Foley catheter balloons have been developed and tested to accurately determine their effectiveness. In this study, it was decided to retrospectively evaluate two induction of labor (IOL) protocols. The last 300 eligible patients who met the criteria and underwent the low-volume balloon protocol (40-60 mL) IOL were selected. Then next, 300 patients who met the criteria and underwent high-volume balloon (80-100 mL) IOL were selected. Outcomes included time to delivery and parturition type, oxytocin augmentation, operative deliveries and application of intrapartum anesthesia. Overall, the majority of patients delivered within 24 h. Patients who received a high-volume Foley catheter had statistically significantly more vaginal deliveries. The mean-time to delivery in the high-volume catheter group was statistically significantly shorter than in the low-volume catheter group. Patients who received a high-volume Foley catheter required statistically significantly less oxytocin augmentation during induction of labor compared to patients with a low-volume Foley catheter. Regardless of the balloon volume used, the percentage of operative deliveries remained at a similar, low level (8.36% and 2.14%). Regardless of the catheter volume used, the majority of patients chose epidural over intravenous anesthesia. In conclusion, a high-volume balloon Foley catheter IOL is characterized by an increased percentage of vaginal deliveries, shortened time to delivery regardless of the type of delivery, and lower need for oxytocin augmentation.
