pudendal block
Pronunciation: pyoo-DEN-dal
Regional anesthesia technique involving injection of local anesthetic near the pudendal nerve to provide perineal analgesia during delivery.
Full Definition
A pudendal block is a regional anesthesia technique used to provide pain relief during the second stage of labor and for perineal procedures. The procedure involves injection of local anesthetic (typically lidocaine or bupivacaine) near the pudendal nerve as it passes around the ischial spine on each side of the pelvis. This provides anesthesia to the perineum, lower vagina, and vulva, making it useful for episiotomy, perineal repair, or assisted vaginal delivery. The block is performed transvaginally using a specialized needle guide and is considered safe with minimal maternal or fetal risk. It provides targeted analgesia without the motor blockade associated with epidural anesthesia.
Usage
Usage note: Anatomical term derived from Latin 'pudenda' meaning shameful parts; ensure correct spelling.
