Labor and delivery: Pain medications

Local anesthetic injection

Description

A local anesthetic might be used to quickly numb the vaginal area if you need an incision to extend the opening of the vagina (episiotomy) or repair a tear after delivery. The medication is injected into the area around the nerves that carry feeling to the vagina, vulva and perineum.

Pros

Local anesthetics temporarily numb a specific area. Negative effects for mother and baby are rare.

Cons

Local anesthetics don't relieve the pain of contractions. An allergic reaction is possible. Rarely, injecting local anesthetics into a vein might produce a toxic reaction, affecting your central nervous system or heart.
