Effect of Video Laryngoscopy Versus Conventional Laryngoscopy Upon Hemodynamics

In general anestheisa airway is secured by passing a tube down the widpipe. This helps the patient to breath via ventilator during anesthesia. For placing this tube laryngoscopy is done which results in increase in blood pressure and heart rate. This study will compare the rise in blood pressure and heart rate among when using video laryngoscope with conventional laryngoscope.

About this study

In this study Patients will be randomly divided into two groups with group V patients being intubated using Videolaryngoscope while group M patients will be intubated using Macintosh laryngoscope. The amount of rise in blood pressure and heart rate as a result of laryngoscopy will be noted.
