Pudendal (Description: For Forceps delivery, Pudendal block is supplemented with perineal & Labial infiltration)
Pudendal anesthesia, also known as a pudendal block, or saddle block, is a form of local anesthesia commonly used in the practice of obstetrics to relieve pain during the delivery of baby by forceps.
The pudendal nerve block prevents fainting during forceps delivery which was common before pudendal nerve block use was available.
The anesthesia is produced by blocking the pudendal 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.
