Doctors in this department give anesthetic for operations and procedures. An anesthetic is a drug or agent that produces a complete or partial loss of feeling. There are three kinds of anesthetic general, regional and local. Anesthesia or anaesthesia (from Greek "without sensation") is a state of controlled, temporary loss of sensation or awareness that is induced for medical purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness.
