Some types of anesthesia are local, general and regional anesthesia. Regional anesthesia includes peripheral nerve blocks, and epidural and spinal anesthesia, according to WebMD. The anesthesiologist decides which type to use, based on a patient’s health, type of procedure and test results.
A local anesthesia is a numbing medication that the anesthesiologist administers to stop pain in a particular area, states Johns Hopkins Medicine. He injects the anesthetic directly into a small section of the body.
A regional anesthesia is a numbing agent that blocks pain to a larger region of the body, explains WedMD. A peripheral nerve block is an injection to stop the pain surrounding a nerve or groups of nerves that affect a part of the body. Doctors provide nerve blocks to feet, legs, face, arms and hands. Epidural and spinal anesthesia are injections to block pain from larger regions of the body, such as the legs, hips or belly.
General anesthesia is a combination of sedative, anesthetic and narcotic agents that the doctor administers intravenously or via inhalation to induce unconsciousness during surgery, explains Madison Anesthesiology Consultants. The doctor also uses it to control pain.
