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.
摘要：
Foley导管的使用是最古老的已知引产方法之一。因此,已经开发并测试了使用不同体积的Foley导管球囊的方案，以准确确定其有效性。在这项研究中,我们决定对两种引产(IOL)方案进行回顾性评估.选择符合该标准并接受低容量球囊方案(40-60mL)IOL的最后300例符合条件的患者。然后接下来,选择符合标准并接受高容量球囊（80-100mL）IOL的300例患者。结果包括分娩时间和分娩类型，催产素增强,手术分娩和产时麻醉的应用。总的来说,大多数患者在24小时内分娩。接受高容量Foley导管的患者在统计学上有更多的阴道分娩。高容量导管组的平均分娩时间在统计学上明显短于低容量导管组。与使用低容量Foley导管的患者相比，接受高容量Foley导管的患者在引产期间需要统计学上明显减少催产素的增加。不管使用了多少气球,手术分娩的百分比保持在相似的水平，低水平（8.36%和2.14%）。无论使用多少导管,大多数患者选择硬膜外麻醉而不是静脉麻醉。总之,高容量球囊Foley导管人工晶状体的特点是阴道分娩的百分比增加,缩短交货时间，无论交货类型如何，并降低催产素增强的需求。
