<unk> , also known as a<unk>  block, or saddle block, is a form of local<unk>  commonly used in the practice of obstetrics to relieve pain during the delivery of baby by forceps. The<unk>  nerve block prevents fainting during forceps delivery which was common before<unk>  nerve block use was available. The<unk>  is produced by blocking the<unk>  nerves near the ischial spine of the pelvis. The ischial spine separates the greater and lesser sciatic foramina at the exit of the bony pelvis. The<unk>  block gets its name because a local anesthetic, such as lidocaine or chloroprocaine, is injected into the<unk>  canal where the<unk>  nerve is located. This allows quick pain relief to the perineum, vulva, and vagina. A<unk>  block is usually given in the second stage of labor just before delivery of the baby. It relieves pain around the vagina and rectum as the baby comes down the birth canal. It is also helpful just before an episiotomy. Lidocaine is usually preferred for a<unk>  block because it has a longer duration than chloroprocaine which usually lasts less than one hour.
