Intrathecal anesthesia; Subarachnoid anesthesia; Epidural
Spinal and epidural anesthesia are procedures that deliver medicines that numb parts of your body to block pain. They are given through shots in or around the spine.
The doctor who gives you epidural or spinal anesthesia is called an anesthesiologist.
First, the area of your back where the needle is inserted is cleaned with a special solution. The area may also be numbed with a local anesthetic.
