Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* The enrolled patients were given a bolus of sufentanil 0.3-0.5μg/kg to achieve Ramsay sedation score 2-3. The Cormack-Lehane score in sedation was evaluated by McGrath videolaryngoscope.
* Then the patients were induced with propofol. A bolus of rocuronium was given to facilitate intubation. The Cormack-Lehane score in anesthesia was recorded when intubated by McGrath videolaryngoscope.
* BMI, mouth opening, thyromental distance, intubation duration and ramsay sedation score were also recorded.
* To compare the Cormack-Lehane score in sedate and anesthesia condition
