Pudendal block
Description
A pudendal block might be used shortly before delivery to block pain between the vagina and anus (perineum). It can also be used to relieve pain during the repair of a tear after delivery. The anesthetic is injected into the vaginal wall near the pudendal nerve and takes effect in 10 to 20 minutes.
Pros
A pudendal block relieves pain in the lower vagina and perineum for up to an hour. Negative effects for the baby are rare.
Cons
A pudendal block might not work or might affect only one side of the perineum. An allergic reaction is possible. Rarely, a pudendal block can cause an infection at the injection site, and injecting the medication into a vein might affect your central nervous system or heart.
