Effect of Dexmedetomidine on Stress-induced Changes in Hemodynamics and Left Ventricular Function in Coronary Artery Bypass Graft Surgery Outcome
Effect of Dexmedetomidine on Stress-induced Changes in Hemodynamics and Left Ventricular Function in Coronary Artery Bypass Graft Surgery Outcome
50 patients of both sexes undergoing elective CABG surgery will be randomly divided into 2 groups, study group (Dex) group and control group (C) to determine the effect of dexmedetomidine on the peri-operative hemodynamic changes during CABG surgery.
The effect of dexmedetomidine during CABG surgery is studied regarding Ventricular function, pre bypass and post bypass using the transoeophageal echo (TEE), post-operative by transthoracic echocardiography (TTE) on day of surgery and after extubation.
Incidence of intraoperative and post operative ischemia and arrhythmias using Electrocardiogram (ECG) as well as the length of ICU and hospital stay.
