Meyer overton anesthesia
WebbAccording to the Meyer-Overton rule, anesthetic potency of a substance can be predicted by its lipid solubility, but a group of halogenated volatile compounds predicted to induce anesthesia does not obey this rule. Thus, these compounds are useful tools for studies of molecular targets of anesthetics. Webb1 juli 1979 · This was first recognized by H. H. Meyer and by Overton, both in 1901, and the lipid solubility theory that they proposed has been expressed in modern form by K. H. Meyer in 1937, who said that "Narcosis commences when any chemically indifferent substance has attained a certain molar concentration in the lipids of the cell.
