[The Stadium analgeticum - Historical Highlights on the Ether Rush]

For decades, the term ether rush was synonymous with the practice of short-term anaesthesia, among patients and doctors. The term was first used shortly after the discovery of the anaesthetic properties of ether by Hamburg-based physician Elias Salomon Nathan in an article about the newly discovered ether anaesthesia. Decades later, the surgeon Paul Sudeck, who also worked in Hamburg, also described an anaesthetic technique he practiced as an ether rush and met with great approval from his surgical colleagues, as well as for his anaesthetic mask developed for carrying out the ether rush and the anaesthetic dropper, specified for this purpose.Sudeck did not want to be regarded as the inventor of the special anaesthetic technique and repeatedly pointed out that his procedure had already been described and applied before him, but was forgotten again. Nevertheless, Sudeck's ether rush remained a well-known, widespread analgesic method in German-speaking countries until the end of the 1940s, and it proved its worth many times during the World War. After 1945, when ether lost its pre-dominant role as an inhalation anaesthetic and was replaced by other, new agents and short-acting i. v. administered analgesics, the ether rush was also fell into oblivion and was no longer used.Against the background of the first successfully performed ether anaesthesia on October 16th, 1846 - 175 years ago - at the Massachusetts General Hospital in Boston, the description of the ether rush should be recalled in this context.
