Evaluation of Truview evo2 Laryngoscope In Anticipated Difficult Intubation - A Comparison To Macintosh Laryngoscope.

The aim of the study was to assess and compare laryngoscopic view of Truview evo2 laryngoscope with that of Macintosh laryngoscope in patients with one or more predictors of difficult intubation (PDI). Moreover ease of intubation with Truview evo2 in terms of absolute time requirement was also aimed at. Patients for elective surgery requiring endotracheal intubation were initially assessed for three PDI parameters - modified Mallampati test, thyro-mental distance & Atlanto-occipital (AO) joint extension.
