An evaluation of the TruView EVO2 laryngoscope.

The TruView EVO2 laryngoscope was compared with the traditional Macintosh laryngoscope in 200 patients who required tracheal intubation for elective surgery. Mallampati score determined prior to laryngoscopy was significantly related to the view of the glottis during laryngoscopy for both laryngoscopes. The view of the larynx was better with the TruView EVO2 laryngoscope than with the Macintosh laryngoscope in patients with a Cormack and Lehane grade greater than 1 (p < 0.01). The mean time to intubate was significantly shorter with the Macintosh laryngoscope (34 s) than with the TruView laryngoscope (51 s) (p < 0.01).
