Tracheal Intubation of Morbidly Obese Patients. GlideScope Versus Direct Laryngoscopy

February 23, 2010 updated by: Glostrup University Hospital, Copenhagen

Orotracheal Intubation of Morbidly Obese Patients. A Randomised Controlled Trial Comparing the GlideScope Videolaryngoscope to the Macintosh Direct Laryngoscope.

The purpose of this study is to examine whether orotracheal intubation in morbidly obese patients is faster, gentler and safer using the GlideScope videolaryngoscope than with the Macintosh direct laryngoscope.
