Abstract
McCoy laryngoscope is reported to improve the laryngeal view of the vocal cord compared to a Macintosh laryngoscope. This study reports the beneficial effect of the McCoy laryngoscope in tracheal intubation in patients with difficult airways. Ninety-five patients in whom tracheal intubation with the Macintosh laryngoscope failed were studied. The laryngeal view (Cormack and Lehane classification) was compared between the two laryngoscopes. G1: G2: G3: G4 was 1 24: 66: 4 with the Macintosh laryngoscope, and 18: 55: 22: 0 with the McCoy laryngoscope (p<0.0001). All the patients could be intubated orally with the McCoy laryngoscope.
The McCoy laryngoscope was an effective device to intubate the difficult adult airways.
