Spinal Anesthesia

Spinal anesthesia may be chosen for surgical procedures performed on the lower half of the body. In this case, a needle will be inserted at waist level between the bones of the spine into the space containing spinal fluid. A local anesthetic agent is injected to numb the nerves coming from the spinal cord, and you will temporarily lose feeling and ability to move the lower part of your body. You may remain conscious or may receive sedation if you wish. In rare instances (less than 1 percent) when spinal anesthesia is used, you may experience a post-spinal headache. However, the smallest gauge needle possible will be used so the incidence of a headache will be minimal. Also, during spinal or epidural anesthesia, you may experience a higher than planned level of anesthesia resulting in temporary low blood pressure or nausea.
