Protocol summary

Summary
Objective: To comparison the effectiveness of dexmedetomidine with midazolam on incidence of cardiac arrhythmia in off-pump coronary artery bypass surgery patients. Design: A single blind block randomized clinical trial. Study population: Patients will be undergoing off-pump coronary artery bypass surgery. Inclusion criteria: Patients undergoing off-pump coronary artery bypass surgery; sustaining ASA I and ASA II; aged between 18-75 years; EF more than 35%. Exclusion criteria: History of arrhythmias or heart block; EF less than 35%; history of cardiac surgery; history of valvular heart disease; having left atrial enlargement (LAE) or cardiomegaly. Sample size: 70 cases. Study intervention: Control group is receiving 0.5 mg/kg midazolam addition of 10 mcg/kg fentanyl, 0.5 mg/kg atracurium, and 1.5 mg/kg propofol for induction of anesthesia. Interventional group is receiving 1 mcg/kg dexmedetomidine infusion for induction of anesthesia for 10 minutes, and then infusion is fallowing up with 0.2 to 0.6 mg/kg/h based on tolerance of patient for MAP decreased in ICU after surgery until 24 hours. Study outcome: Evaluation and comparison of cardiac arrhythmia rate, hemodynamic changes, the urge to use anesthetic drugs, heart block, myocardial infarction, and cardiac arrest with heart monitoring in control and interventional groups during and after surgery.
