Almost a year later, an Adelaide newspaper, The South Australian Register, reproduced a poem about chloroform from the British satirical magazine Punch. This poem, ‘The Blessings of Chloroform’, has been attributed to Percival Leigh, a British medical practitioner who became a comic writer.

The device was an alternative to the inflatable cuff used on tracheal tubes. Guedel did not publish a description of the laryngeal plug and the most detailed description of it was published by Gilbert Troup, an Australian anaesthetist.

In March 1848, Andrew Buchanan, MD, of Glasgow, Scotland, penned a letter to Simpson to suggest a more semantically precise word, the spelling of which is not clear in Buchanan's letter. We do not know whether Simpson replied to Buchanan. Simpson continued using the words anaesthesia and anaesthetic in his publications.

After working as a ship’s surgeon, he settled in Australia. In May 1875, Thomas presented a paper on the mortality from ether and chloroform at a meeting of the Medical Society of Victoria in Melbourne, Victoria. Surveys conducted in Europe and North America had established that the mortality from chloroform was eight to ten times higher than that from ether. At that time, chloroform was the most widely administered anaesthetic in Australia. Thomas’ paper was published in The Australian Medical Journal and reprinted by the Medical Society of Victoria for distribution to hospitals in the Colony of Victoria. Later that year, Thomas moved to Adelaide, South Australia, where he may have been influential at the Adelaide Hospital in ensuring that ether was administered more often than chloroform. It does not appear that Tho...

Morton secured a provisional English patent for etherization in December 1846. The full patent specification was submitted 6 months later, and the patent was sealed on June 18, 1847. The enrolled copies of the provisional and full patents, which are held in The National Archives, London, have not been previously documented in the anesthesia literature. We review the communications between Boston and London regarding the patent for etherization, the possibility that preliminary discussions and trials of etherization may have been conducted in London before the earliest known application of the discovery for a dental extraction on December 19, 1846, and the role of the American lawyer James Augustus Dorr, who was Morton's agent in the United Kingdom.

The Leech airway formed a seal with the pharyngeal tissues, resulting in a closed system during cyclopropane anaesthesia. Two prototypes and four commercially available versions of the airway have been identified.

Both groups received alfentanil 15 micrograms/kg, thiopentone 3-4 mg/kg and vecuronium 0.1 mg/kg and were ventilated with oxygen, nitrous oxide and isoflurane for 3 minutes prior to laryngeal mask insertion or tracheal intubation. Blood pressure and heart rate decreased equally in both groups after induction of anaesthesia. Haemodynamic variables increased after tracheal intubation but were unchanged after laryngeal mask insertion (P < 0.05 for intergroup differences). Heart rate, but not blood pressure, increased above baseline levels in the tracheal intubation group. The anaesthetic technique used blunted the haemodynamic response to tracheal intubation, but completely blocked the response to laryngeal mask insertion.
