The nerve root blocked in pudendal nerve block
Correct Answer: S2-4
Description: Pudendal nerve block, blocks sacral segments (S2-4) thus provides perineal analgesia. The anesthesia is produced by blocking the pudendal nerves near the ischial spine of the pelvis. The pudendal block gets its name because a local anesthetic, such as lidocaine or chloroprocaine, is injected into the pudendal canal where the pudendal nerve is located. Ref Robbins 9/e pg 345
