Randomized Controlled Trial
[Efficacy of bougie in difficult intubation with the Airway Scope caused by inability to lift the epiglottis directly].
There are some disadvantages of the Airway Scope (AWS), and the most crucial one is that the AWS has only one fixed-size AWS blade. When the blade is too short to reach beneath the epiglottis and to lift it directly, an endotracheal tube hits the epiglottis and cannot be advanced into the glottic aperture even when it is visible. A bougie may solve this difficulty because its angulated tip can be controlled in a desired direction. Therefore, we examined the efficacy of the bougie on this problem. ⋯ Use of the bougie was useful for difficult intubation with the AWS caused by inability to lift the epiglottis directly.
