EFFECT OF DEXMEDETOMIDINE VERSUS LABETALOL FOR ATTENUATION OF HEMODYNAMIC STRESS RESPONSE TO LARYNGOSCOPY AND INTUBATION

Abstract

Introduction: In the field of anaesthesiology, attenuation of pressor response is one of the keenly researched subjects. As a standard practice we use rigid laryngoscope to view the larynx and adjacent structures for facilitating endotracheal intubation. This causes direct trauma to the oropharynx and larynx and apart from this it also causes stimulation resulting in a rise in heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure. Tachycardia, hypertension, and dysrhythmias all occur during laryngoscopy and intubations.
