In the practice of medicine, anesthesia or anaesthesia is a temporary induced loss of sensation or awareness. It may include analgesia, paralysis, amnesia or unconsciousness.
It is used because enables the painless performance of medical procedures that would cause severe or intolerable pain to an unanesthetized patient.
In preparing for a medical procedure, the health care provider giving anesthesia chooses and determines the doses of one or more drugs to achieve the types and degree of anesthesia characteristics appropriate for the type of procedure and the particular patient. The types of drugs used include general anesthetics, hypnotics, sedatives, neuromuscular-blocking drugs, narcotic, and analgesics.
