Loss of sensation
Administration of multiple drugs concurrently in smaller quantities than would be required if each were given alone, to produce sedation, tranquilization, muscle relaxation, analgesia, or a variety of other effects needed for a particular patient.
Regional anesthesia produced by injection of a local anesthetic or analgesic into the epidural space surrounding the spinal cord.
A reversible state of unconsciousness, immobility, muscle relaxation, and loss of sensation throughout the entire body produced by administration of one or more anesthetic agents.
A sleeplike state from which the patient can be aroused with sufficient stimulation.
A loss of sensation in a small area of the body produced by administration of a local anesthetic agent in proximity to the area of interest.
A drug-induced sleep from which the patient is not easily aroused and that is most often associated with the administration of narcotics.

A drug-induced CNS depression and drowsiness.
A specific stage of general anesthesia in which there is a sufficient degree of analgesia and muscle relaxation to allow surgery to be performed without pain or movement.
A ratio of the toxic to the therapeutic dose of a drug, used to measure relative safety.
A drug with a wide therapeutic index (much more of the drug is required to intoxicate a patient than is required to treat it) is relatively safer than a drug with a narrow therapeutic index (one for which the toxic and therapeutic doses are similar).
A loss of sensation of a localized area produced by administration of a local anesthetic directly to a body surface or to a surgical or traumatic wound.
