Pudendal Block
Regional nerve block technique targeting the pudendal nerve to provide perineal anesthesia for delivery or episiotomy repair.
Full Definition
Pudendal block is a regional anesthetic technique that involves injecting local anesthetic around the pudendal nerve as it passes near the ischial spine and sacrospinous ligament. This block provides anesthesia to the perineum, including the lower vagina, vulva, and posterior portion of the labia, making it useful for spontaneous vaginal deliveries, episiotomy procedures, and perineal repairs. The technique can be performed via transvaginal or transcutaneous approaches, typically using a guide needle system. While less commonly used since the widespread adoption of neuraxial anesthesia, pudendal blocks remain valuable when epidural anesthesia is not available or contraindicated, or when additional perineal anesthesia is needed after delivery.
Usage
Usage note: Specify approach (transvaginal vs transcutaneous) and indication.
