Comparison of McGrath Videolaryngoscopy and Direct Laryngoscopy for Intubation in Patients With Morbid Obesity in Non-cardiac Surgery
In Brief
A clinical study evaluating McGrath videolaryngoscopy and Direct laryngoscopy for Morbid Obesity. Completed, enrolled 130 participants across 1 site.
Detailed 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.
Study Details
Timeline
Interventions
Intubations will be performed with a regular endotracheal tube of adequate diameter, usually 7.5 mm or 8.0 mm. Endotracheal tubes will be equipped with a hockey-stick-shaped stylette, which will be prepared by the anesthesiologist in advance. The McGrath or the Macintosh blade will be introduced into oral cavity according to manufacturer recommendations and clinical practice. Minor airway manipulation procedures including BURP or Sellick maneuvers will be allowed to improve visualization of the vocal cords.
