Paracervical block

Paracervical block is placed by injecting a total dose of 10 to 20 mL of anesthetic agent (usually 1% lidocaine or 2-chloroprocaine) approximately 10 mm into the cervical stroma at the 4 and 8 o'clock positions (some operators inject at the 2, 4, 8, and 10 o'clock positions) at the cervicovaginal junction.
