Macewan-type endotracheal tubes, United Kingdom, 1871-1900

William Macewan (1848-1924), a Glasgow surgeon, invented this type of endotracheal tube. He was the first person to use an endotracheal tube to give a patient anaesthetic, in 1878. A tube was placed in the larynx to give the patient a dose of chloroform. These examples are made from steel and brass. They range in length from 210 mm to 80 mm for patients of all sizes.
