Endotracheal Intubation
Friedrich Trendelenburg performed the first endotracheal anaesthetic in 1869, followed by William Macewen’s orotracheal intubation in 1880. Franz Kuhn laid the foundations, and Ivan Magill refined the technique after the First World War. The laryngoscope, muscle relaxants, and cuffed tubes made intubation routine, transforming it into the cornerstone of modern anaesthesia.
