World Anaesthesia Day
World Anesthesia Day commemorates the first successful demonstration of ether anesthesia on October 16, 1846. This ranks as one of the most significant events in the history of medicine and took place at the Massachusetts General Hospital, home of the Harvard School of Medicine. The discovery made it possible for patients to obtain the benefits of surgical treatment without the pain associated with an operation. The date (16 October) is now globally recognised as World Anaesthesia Day in respect of the importance of this event.
