Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Several studies demonstrate mifepristone's efficacy and safety as a cervical ripening agent for up to 16 weeks' gestation, however, despite its effectiveness, mifepristone for cervical preparation before procedural abortion has previously been limited by availability and cost. Recent studies demonstrating mifepristone's adjunctive benefit with osmotic dilators later in pregnancy, however, have broadened its use.
While most abortion care in the United States occurs in outpatient settings, about 3% occur in hospitals. This is expected to increase as the Dobbs versus Jackson Women's Health Organization decision exacerbates disparities in abortion access. In hospital-based abortion care, particularly at academic centers providing abortion training, there is a pressing need for innovative measures for cervical ripening. The Complex Family Planning Fellowship-trained faculty members at Montefiore will serve as research study surgeons. Cases will be performed in the main operating room under sedation or general anesthesia as determined by the anesthesiologist. A paracervical block of 20cc 1% lidocaine, with or without vasopressin, will be administered in accordance with standard practices.
