When his original article was published in "The Lancet" in February 1943, Dr. MacIntosh probably did not foresee the impact his new design would have on anesthesiology. Currently, the most popular of all curved-blade styles, the MacIntosh blade, has survived virtually unchanged since its conception. The idea for this blade originated from two previous papers. The first, published by J.V. Human in 1941, discussed passing the laryngoscope only until the epiglottis comes into view and then passing an endotracheal tube behind the epiglottis. The procedure reduced dental and posterial pharyngeal wall trauma.
The second article, published in 1942 by W.H. Cassels, discussed the importance of the curve, provided by the Miller blade, in compression of the epiglottis. These earlier blades helped to inspire the MacIntosh blade, a design that incorporates a gentle, continuous curve from the tip to the proximal end. The curve is compressed into the vallecula and the blade "lifted," indirectly raising the epiglottis. Welch Allyn recently modified our MacIntosh blades by reducing proximal blade height. This results in a lower profile that assists in intubating patients with limited oral access.
