Introduction

Since the time of inception of endotracheal anesthesia in the last quarter of 19^th century, endotracheal intubation has become one of the very common procedures performed in the practice of anesthesia. We have a novel drug from the family of alpha-2 adrenergic agonist, Dexmedetomidine, which is a D-isomer of medetomidine. It is more specific for alpha-2 adrenergic receptor and shorter acting than clonidine. In recent study this drug has been shown to have clinically significant effects on anesthetic requirements, hemodynamic responses induced by anesthesia and surgery in patients. This study is an attempt to assess the safety and efficacy of dexmedetomidine in attenuating hemodynamic responses to laryngoscopy and endotracheal intubation.
