Since 1982, ether is not used in the United States. [7] Now, because of the use of intravenous induction agents with muscle relaxants and the discontinuation of ether, elements of Guedel's classification have been superseded by depth of anaesthesia monitoring devices such as the BIS monitor; [5] however, the use of BIS monitoring remains ...
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 .
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.
Chloroform is a much stronger and effective anaesthetic than ether, it is non-inflammable and it did not irritate the airways, unlike ether. First non-gaseous inhalational anaesthetics such as ether and chloroform were inhaled from a handkerchief which the liquid was poured on and allowed to evaporate.
Drinking ether is challenging as it boils below body temperature and is not miscible with water, requiring precautions: . There is an art in swallowing the ether. The drinker first washes out his mouth with water “to cool it;” next he swallows a little water to cool his throat; then he tosses down the glass of ether; finally, he closes in with another draught of water to keep the ether ...
Historically, ether (the first volatile agent) was first used by John Snow's inhaler (1847) but was superseded by the use of chloroform (1848). Ether then slowly made a revival (1862–1872) with regular use via Curt Schimmelbusch's "mask", a narcosis mask for dripping liquid ether. Now obsolete, it was a mask constructed of wire, and covered ...
Sevoflurane, sold under the brand name Sevorane, among others, is a sweet-smelling, nonflammable, highly fluorinated methyl isopropyl ether used as an inhalational anaesthetic for induction and maintenance of general anesthesia. After desflurane, it is the volatile anesthetic with the fastest onset. [8]
Newer anesthetics (such as desflurane) typically have smaller blood–gas partition coefficients than older ones (such as ether); this leads to faster onset of anesthesia and faster emergence from anesthesia once application of the anesthetic is stopped, which may be preferable in certain clinical scenarios.
