Pudendal block

Pudendal block is a type of local anesthesia commonly used in obstetrics to alleviate pain during labor and delivery. It is named after the pudendal nerve, which it targets to numb the perineum, vulva, and vagina.

Procedure

The pudendal block is administered by injecting a local anesthetic into the pudendal canal where the pudendal nerve is located. This is usually done through the vaginal wall using a special needle. The procedure is typically performed during the second stage of labor, just before delivery.

Uses

The primary use of a pudendal block is to provide pain relief during childbirth. It is particularly effective for pain in the lower vagina and perineum. It can also be used during repair of perineal tears or an episiotomy after delivery.

Benefits

The main benefit of a pudendal block is that it provides effective pain relief without affecting the mother's consciousness or the baby's heart rate. It also does not interfere with the mother's ability to push during delivery.

Risks and complications

While generally safe, a pudendal block does carry some risks. These include bleeding, infection, and nerve damage. There is also a small risk of the anesthetic spreading to other parts of the body.
