What is a Pudendal Nerve Block?
A pudendal nerve block is an injection used to reduce pain in the second stage of labour. The pudendal nerve is a major nerve found in the pelvis. This nerve carries sensation to the vagina, vulva, and perineum (the area between the vagina and anus). When a pudendal nerve block is injected, it numbs the vaginal, vulval, and perineal area.When is a Pudendal Nerve Block Given?
A pudendal nerve block is administered in advanced labour when there is not enough time for an epidural. A pudendal nerve block is offered at the time of labour in the following situations:- During the pushing stage of labour.
- If you’re having an assisted delivery with forceps or a vacuum.
- Before or after an episiotomy.
Where is a Pudendal Nerve Block Administered?
A pudendal nerve block is delivered through three approaches. Your healthcare provider will choose the best route to deliver the injection. These three approaches include:- Transperineal (through the perineum)
- Transvaginal (through the vagina)
