Abstract:
We describe the clinical use of a new video-laryngoscope (GlideScope, GS) in patients with a difficult airway and morbid obesity. In 4 patients with a difficult airway, showing a Cormack-Lehane grade III view with Macintosh direct laryngoscope, the glottic opening (Cormack-Lehane grade I or II) was visualized with GS. In 2 patients, showing a Cormack-Lehane grade IV view with Macintosh direct laryngoscope, Cormack-Lehane grade II view of the glottic opening was obtained. GS also provided a good view of glottic opening in a patient with morbid obesity. GS will have a profound impact on the management of the difficult airway.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
