Abstract

<abstract abstract-type="main" id="anae12075-abs-0001"> <title>Summary</title> <p>We compared the McGrath^® Series 5 videolaryngoscope with the Macintosh laryngoscope in a simulated difficult airway, using manual in‐line stabilisation in 88 anaesthestised patients of ASA physical status 1‐2. The primary outcome was laryngoscopic view. Secondary outcomes included rates of successful tracheal intubation and complications. A Cormack and Lehane grade‐1 or ‐2 view was found in all patients when using the McGrath compared with 45 (51%, p &lt; 0.0001) using the Macintosh laryngoscopes. The mean (SD) percentage of glottic opening was 82 (23)% using the McGrath compared with 13 (23)% using the Macintosh (p &lt; 0.0001). In 66 out of 88 patients (75%), the McGrath improved the glottic view by one to three grades compared with the Macintosh (p &lt; 0.001). Intubation of the trachea was successful in all patients using the McGrath, while the Macintosh was successful in 26 (59%, p &lt; 0.001). There was no significant difference in the complication rates between the devices.</p> </abstract>
