Pudendal and paracervical blocks are single-injection nerve blocks that are commonly used during obstetric and gynecologic procedures. These blocks are typically administered by an obstetrician or gynecologist, rather than an anesthesiologist, and are easy to learn and simple to perform.

This topic will review the indications, technique, efficacy, and risks of pudendal and paracervical blocks in obstetrics and gynecology. Related topics on nerve blocks are presented elsewhere.

(See "Overview of peripheral nerve blocks".)

(See "Anesthesia and anesthetic choices".)


Pudendal and paracervical blocks are single-injection, or single-shot, nerve blocks that involve a one-time injection of local anesthetic adjacent to the nerve or plexus for pain relief. The duration and density of the block depends upon the dose, concentration, and pharmacology of the chosen local anesthetic. (See "Overview of peripheral nerve blocks", section on 'Single injection'.)
