Cervical Ripening: Single vs Double Balloon Catheters

Using mechanical options as a way to prime/ripen the cervix for labor is nothing new. Balloon catheters have been used for labor induction as far back as the 1890s. Embrey and Mollison reinvigorated the method in 1967 using it in combination with extraamniotic prostaglandins. Since then numerous studies have been performed worldwide, mostly using the Foley catheter. Then, in 1990, the double balloon catheter was introduced by Atad; this paved the way for the Cook Balloon. But what is the best way to use a balloon for cervical ripening? Should be a single balloon or a double balloon? If single balloon, does volume of the balloon matter? Should it be used alone or with combination with a second agent? Can it be used safely as an outpatient procedure? In this episode, we will present new data regarding traction vs no-traction for single balloon cervical ripening therapy. This new study was published on March 1, 2024 in Obstetrics and Gynecology (the Green Journal).
