Study Summary
Our goal is to compare conventional direct laryngoscopy using a Macintosh blade with the McGrath videolaryngoscope for endotracheal intubation in very morbidly obese patients undergoing non-cardiac surgery. Specifically, we propose to test the primary hypotheses that videolaryngoscopy improves visualization of the vocal cords, defined with modified Cormack and Lehane classification, compared to direct laryngoscopy.
Primary Outcome
Glottis visualization is evaluated according to the modified Cormack and Lehane classification. It is a grading system from 1 to 4: 1 = full view of glottis; 2a = partial view of glottis;2b = only posterior extremity of glottis seen or only arytenoid cartilages; 3 = only epiglottis seen, none of glottis seen; 4 = neither glottis nor epiglottis seen.
Interventions
- DEVICE Direct laryngoscopy
- DEVICE McGrath videolaryngoscopy
