pudendal nerve block
Pronunciation: pyoo-DEN-dal
Regional anesthesia technique targeting the pudendal nerve to provide pain relief for perineal procedures during delivery.
Full Definition
A pudendal nerve block is a regional anesthetic technique that targets the pudendal nerve as it passes behind the ischial spine. This procedure provides anesthesia to the perineum, posterior vulva, and lower vagina, making it useful for episiotomy repair, perineal laceration repair, and assisted vaginal delivery. The block is typically performed transvaginally using a needle guide to locate the ischial spine. While generally safe, potential complications include intravascular injection, hematoma formation, and incomplete anesthesia. The block has largely been supplemented by epidural anesthesia in modern obstetric practice.
Usage
Usage note: Specify bilateral vs unilateral and document anesthetic agent and dosage used.
