The history of airway management has become an issue of concern for clinicians because of the remarkable advances that have occurred in airway management in recent years. Endotracheal intubation became a routine medical practice in the second half of the 20 th century. Thereafter, progress was made in modern anesthesia and thoracic surgery. As the number of intubated patients increased, the need for a more effective placement of the tube also increased. (JAEM 2015; 14: 35-6)
