A paracervical block is an anesthetic procedure used in obstetrics and gynecology, in which a local anesthetic is injected into between two and six sites at a depth of 3–7 mm alongside the vaginal portion of the cervix in the vaginal fornices.
It is used for various obstetric and gynecologic procedures, such as hysteroscopy and vacuum aspiration. It is as efficient as intracervical block, according to a study on women undergoing vacuum aspiration with lidocaine as anesthetic agent.
