Abstract
In 1846 Oliver Wendell Holmes coined the term anesthesia from the Greek word “anaesthesia” meaning “without sensation,” after William T.G. Morton, a Boston dentist, performed the first public demonstration of an inhalational anesthetic (ether). The most accepted current definition of general anesthesia is “a drug-induced, reversible condition composed of the behavioral states of unconsciousness, amnesia, analgesia, and immobility along with physiological stability.” A major challenge to defining ideal state of general anesthesia is the fact that the site and mechanism of action of general anesthetics are not entirely known.
