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 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 ]
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.

In 1877, Clover invented an ether inhaler with a water jacket, and by the late 1899 alternatives to ether came to the fore, mainly due to the introduction of spinal anesthesia. Subsequently, this resulted in the decline of ether (1930–1956) use due to the introduction of cyclopropane, trichloroethylene, and halothane.
Enflurane (2-chloro-1,1,2-trifluoroethyl difluoromethyl ether) is a halogenated ether. Developed by Ross Terrell in 1963, it was first used clinically in 1966. It was increasingly used for inhalational anesthesia during the 1970s and 1980s [2] but is no longer in common use. [3] Enflurane is a structural isomer of isoflurane. It vaporizes ...
Then high-volatility anesthetic (usually diethyl ether or halothane, and historically chloroform) is dripped on it, allowing the patient to inhale a mix of the evaporated anesthetic and air. The device is designed to prevent the anesthetic from coming in contact with the patient's skin, where it can cause irritation.
