Abstract: Background and aim: Laryngoscopy and tracheal intubation are known to evoke the stress responses, Thus, use of different types of laryngoscope blades can help decreasing these responses. The aim of the study was to assess the effect of using McCoy blade laryngoscope and inexpensive video laryngoscope in endotracheal intubation. Methodology: This study included 50 patients, who were divided into 2 groups of 25 each. In group A patients McCoy laryngoscope were used. In group B Inexpensive video laryngoscope were used. Parameters like heart rate (HR), and mean arterial pressure (MAP) were recordedat the baseline, post induction, just after tracheal intubation and at 1, 3, 5 and 10 min post intubation. Any episode of heamodynamic instability was noted. Result: The increase in mean arterial pressure and heart rate was less with Inexpensive video laryngoscope when compared to the McCoy laryngoscope. Themean arterial pressure and heart rate increased after intubation in all groups but returned to baseline within 5 min after intubation in each group. Statistically significant, post laryngoscopy values noted in McCoy group. Conclusion: This study shows that the Inexpensive video laryngoscope require less laryngeal manipulations and force required during intubation, thereby reducing thepotential for haemodynamic variation.
