The use of chloroform anesthesia expanded rapidly thereafter in Europe. Chloroform began to replace ether as an anesthetic in the United States at the beginning of the 20th century. It was soon abandoned in favor of ether when its hepatic and cardiac toxicity, especially its tendency to cause potentially fatal cardiac dysrhythmias, became ...
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induction agents with muscle relaxants and the discontinuation of ether, elements of Guedel's classification have been superseded by depth of anaesthesia monitoring devices such as the BIS monitor; [5] however, the use of BIS monitoring remains ...
Diethyl ether, or simply ether, is an organic compound with the chemical formula (CH 3 CH 2) 2 O, sometimes abbreviated as Et 2 O. [a] It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It belongs to the ether class of organic compounds. It is a common solvent. It was formerly used as a general ...
Subsequently, about 40 years later, in 1581, Giambattista Delia Porta demonstrated the use of ether on humans although it was not employed for any type of surgical anesthesia. [14] In modern medicine, Dr. Horace Wells used nitrous oxide for his own dental extraction in 1844.
After observing the same physiological effects with diethyl ether ("ether") that Humphry Davy had described for nitrous oxide in 1800, Long used ether for the first time on March 30, 1842, to remove a tumor from the neck of a patient, James M. Venable. [7] He administered sulfuric ether on a towel and simply had the patient inhale. [8]
Replica of the inhaler Morton used to administer the ether. Commissioned by William Thomas Green Morton, the Original Morton Etherizer was used on Ether Day as a means of inhalation anesthesia. The Etherizer was made of blown glass with brass fittings at the two open ends, a middle chamber, and a mouthpiece.
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.
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]
