On 30 March 1842, he administered diethyl ether by inhalation to a man named James Venable, in order to remove a tumor from the man's neck. [102] Long later removed a second tumor from Venable, again under ether anesthesia. He went on to employ ether as a general anesthetic for limb amputations and childbirth. Long, however, did not publish his ...
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
The MGH Department of Anesthesia, Critical Care and Pain Medicine traces its roots back to the October 16, 1846 public demonstration of medical ether. Edward Gilbert Abbott (1825–1855) was the patient upon whom William T. G. Morton first publicly demonstrated the use of ether as a surgical anesthetic .
CO 2 anesthesia was first demonstrated to the king of France in the early 1800s by Henry Hill Hickman. Initially CO 2 was thought to work through anoxia, but in the early 1900, increased CO 2 in the lung showed a dramatic increase oxygenation of the brain disproving the anoxia argument. [ 11 ]
Desflurane (1,2,2,2-tetrafluoroethyl difluoromethyl ether) is a highly fluorinated methyl ethyl ether used for maintenance of general anesthesia. Like halothane , enflurane , and isoflurane , it is a racemic mixture of ( R ) and ( S ) optical isomers ( enantiomers ).

Inhaled agents like diethyl ether are critical in anesthesia. Diethyl ether initially replaced non-flammable (but more toxic) halogenated hydrocarbons like chloroform and trichloroethylene. Halothane is a halogenated hydrocarbon anesthetic agent that was introduced into clinical practice in 1956. Due to its ease of use and improved safety ...
