Abstract
Maintenance of airway during anaesthesia is very important to anaesthesiologist. A prospective, randomized study was conducted in300 patients posted for various surgeries under general anaesthesia with endotracheal intubation to evaluate differences in glottic view, attempts of laryngoscopy and intubation attempts associated with the three blades- Macintosh, McCoy and Miller laryngoscope blade. They were allocated in three groups. In first group laryngoscopy was done with Macintosh blade, in second group with McCoy blade, in third group with Miller blade. In this study it was found that Cormack LehaneGrade III view was more with Macintosh and McCoy blade which was more in comparison to Miller blade. Degree of difficulty in intubation was more with Miller blade in comparison to Macintosh and McCoy blade which is statistically significant ( p value < 0.05).
