General Anaesthetic Agents

The mechanism by which anaesthetic drugs produce unconsciousness is still unknown. Meyer in 1899 and Overton in 1901 noted that within any group of drugs, anaesthetic potency correlates well with lipid solubility, and most modern theories agree that the site of action is probably the lipid bilayer of nerve cell mem­branes, or possibly a protein receptor in this sit­uation, but further knowledge is limited.

Inhalational Agents

Anaesthetic practice is unique in that a high proportion of the drugs are administered by the inhalational route. Such agents must either be gaseous, or the vapour of volatile liquids (Vari­ous Authors 1984).
Of the original three inhalational agents – ni­trous oxide, ether and chloroform – the first two are still used widely.
