Abstract

The aim of laryngoscopy is to obtain good visualization of vocal cords to facilitate smooth endotracheal intubation. Many factors have shown to
influence Laryngoscopic view of vocal cords. These include forward displacement of mandible, prominent or absent teeth, backward displacement of tongue. Difficult Mask Ventilation i.e., Bones. Laryngoscopy and endotracheal intubation trigger major stress
response, in the form of increased catecholaminesleading to tachycardia and hypertension, which may be catastrophic in patients with cardiovascular disease.1,2 Present study was done to evaluate the ease
of intubation and there effect on hemodynamic parameters by using two different laryngoscopy blades. Taking Mallampati grading, Cormack and Lehane grading into consideration the various parameters were studied.The McCoy blade, which is a modification of the Macintosh blade with its levering tip significantly reduces the duration of laryngoscopy, improves the visualization of the larynx. less increase in
hemodynamic parameters during laryngoscopy and intubation, early return of hemodynamic parameters towards baseline following intubation.
