The stress produced by anesthesia and surgery may produce undesirable hemodynamic effects. Different agents have been used as preoperative medication to eliminate or suppress stress reactions. We hypothesize Dexmedetomidine provides better hemodynamic control as compared to midazolam when used as a premedication for patients. In this study, we evaluated the effects of a pre-anesthetic single dose of intravenous Dexmedetomidine in a dose of 0.06 mcg/kg body weight with intravenous midazolam 0.05mg/kg body weight on hemodynamic parameters
