16 октября 1846 года хирург и стоматолог из Бостона Уильям Мортон продемонстрировал эфирный наркоз

His colleagues were delighted and expressed their intention to use ether in their daily practice. The World Anesthesia Day celebrated on October 16 is timed specifically to this very demonstration. Less than ten years later, famous Russian surgeon Nikolay Pirogov gave anesthesia in field settings, in Sevastopol besieged by the British and French. Scientific thought knew no boundaries and secrets at that time.
