TL;DRAbstract

The general anaesthetics comprise a large group of compounds of diverse chemical structure which cause a loss of sensation and perception leading in adequate doses to a complete, but reversible loss of consciousness. Although they may cause an attenuation of pain sensation in subanaesthetic doses, this is not invariably so, and the anaesthetics as a class are distinct from the analgesic drugs which selectively reduce the sensation of pain but do not lead to a loss of consciousness at therapeutic concentrations.
