Tracheal intubation of morbidly obese patients: a randomized trial comparing performance of Macintosh and Airtraq™ laryngoscopes

摘要

Background The Airtraq™ laryngoscope is designed to allow visualization of the glottis without alignment of the oral, pharyngeal, and laryngeal axes. We hypothesized that this new airway device would facilitate tracheal intubation of morbidly obese patients. We compared tracheal intubation performance of standard Macintosh laryngoscope with the Airtraq™ laryngoscope in morbidly obese patients.
