epidural anesthesia
produced by injecting local anesthetic agent into the epidural space of the spinal canal at the first or second intercoccygeal space. Injection of a small amount of anesthetic agent produces anesthesia of the perineum without paralysis of the hindlimbs, a low epidural. Injection of a large volume at the same site produces a high epidural. The same effect is achieved by injecting the anesthetic at the lumbosacral or first interlumbar space. Called also extradural anesthesia, or analgesia, extradural block, epidural block.
