Definition (MEDLINEPLUS)

If you are having surgery, your doctor will give you a drug called an anesthetic. Anesthetics reduce or prevent pain. There are four main types.

  • Local: numbs one small area of the body. You stay awake and alert.
  • Conscious or intravenous (IV) sedation: uses a mild sedative to relax you and pain medicine to relieve pain. You stay awake but may not remember the procedure afterwards.
  • Regional anesthesia: blocks pain in an area of the body, such an arm or leg. Epidural anesthesia, which is sometimes used during childbirth, is a type of regional anesthesia.
  • General anesthesia: affects your whole body. You go to sleep and feel nothing. You have no memory of the procedure afterwards.

The type of anesthesia your doctor chooses depends on many factors. These include the procedure you are having and your current health.

Definition (NCI) Treatment with a pharmacological substance that produces a loss of feeling.
Definition (NCI_NCI-GLOSS) A loss of feeling or awareness caused by drugs or other substances. Anesthesia keeps patients from feeling pain during surgery or other procedures. Local anesthesia is a loss of feeling in one small area of the body. Regional anesthesia is a loss of feeling in a part of the body, such as an arm or leg. General anesthesia is a loss of feeling and a complete loss of awareness that feels like a very deep sleep.
Definition (MSH) A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures.
Definition (CSP) state characterized by loss of feeling or sensation; depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures.
