Brief Summary
Difficult tracheal intubation is a cause of severe patient damage and death. There is not a good method to predict it. The McGrath Series 5 video laryngoscope can improve visualization of the glottic structures one to two grades. Moreover unlike a classical laryngoscope with a Macintosh blade, the McGrath provides a view of the glottis without requiring alignment of the oral, pharyngeal and laryngeal axes. In this study, the investigators will use it to compare the Cormack-Lehane score in sedation and anesthesia condition. It helps to know the role of videolaryngoscope in predicting difficult intubation.
