Maintenance of airway during anaesthesia is very important to anaesthesiologist. A prospective, randomized study was conducted in 90 patients (ASA-I & II) posted for various surgeries under general anaesthesia with endotracheal intubation to evaluate differences in glottic view, attempts and duration of laryngoscopy and intubation attempts along with hemodynamic variability associated with the three blades- Macintosh, McCoy and Miller laryngoscope blade. Patients were randomly allocated in three groups. In first group laryngoscopy was done with Macintosh blade, in second group with Miller blade, in third group with McCoy blade.
In this study it was found that McCoy laryngoscope is distinctly superior to the Macintosh and Miller with less hemodynamic changes and better glottic visualization. Degree of difficulty in intubation was more with Miller blade in comparison to Macintosh and McCoy blade which is statistically significant (p value < 0>

Keywords: Cormack lehane grade, Macintosh blade, McCoy blade, Miller blade, Degree of difficulty in intubation.
