McGrath Videolaryngoscopy and Direct Laryngoscopy in Morbidly Obese Patients

Completed · Not applicable

Conditions studied: Morbid Obesity

In brief

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.
