"Perhaps the best-known story in the history of Massachusetts General Hospital is the pivotal discovery and first use of ether as an anesthesia in 1846. But, that surgical first was only the beginning of a series of technological innovations that helped increase patient comfort and survivability during surgery. Warren Zapol, Emeritus Anesthetist-in-Chief of MGH, will discuss how the discovery of ether was only the start in a series of critical care developments. This program was presented as part of the December Middays at the Meeting House series 'Milestone in Public Care: The 200th Anniversary of Massachusetts General Hospital' and was cosponsored by Massachusetts General Hospital."
