AIM: To evaluate the cardioprotective effect of sevoflurane on a beating heart in patients undergoing coronary artery bypass grafting with normal preoperative left ventricular function. METHODS: The randomized controlled study included 32 patients induced withsevoflurane and then randomized to receive either 1 minimal alveolar concentration (MAC) end-tidal concentration of sevoflurane (n=16) or propofol (n=16) 2 to 3 mg kg(-1) hour(-1). The acceleration of the aortic blood flow, cardiac index, heart rate, mean arterial pressure, and central venous pressure were measured 5 minutes after anesthesia induction, at the beginning of ischemia, 15 minutes after ischemia, and 15 minutes after sternum closure. RESULTS: There were no differences in heart rate, mean arterial pressure, and central venous pressure within each group and between groups during surgery. Acceleration increased in the sevoflurane group 15 minutes after ischemia (10.3+/-3.5 m/s(2); P=0.004) and 15 minutes after sternum closure (10.7+/-3.9 m/s(2); P<0.001). Acceleration in the propofol group decreased from the beginning of ischemia (P<0.001) and remained lower 15 minutes after sternum closure (P=0.001 and P=0.024, respectively). Acceleration was higher in the sevoflurane group at the beginning of ischemia and 15 minutes after sternum closure (P=0.017 and P=0.046, respectively). There were no significant differences in cardiac index values within the sevoflurane group. In the propofol group, significant decreases in cardiac index were seen at the beginning of ischemia (P<0.001). There were between-group differences in cardiac index values at the beginning of ischemia and 15 minutes after ischemia (P=0.002, and P=0.011, respectively). CONCLUSION:Cardiac function was better preserved in the patients anesthetized with sevoflurane than in patients anesthetized with propofol.
