Abstract | OBJECTIVE: METHODS: One hundred and thirteen patients undergoing OPCABG were studied. Anesthesia induction was achieved by giving midazolam 0.05 mg/kg, ketamine 0.5 mg/kg, vecuronium 0.13-0.15 mg/kg and fentanyl 5-10 microg/kg. Vecuronium and fentanyl were given as needed, isoflurane and propofol were administered for maintenance. Hemodynamic indexes, ST-segment change in electrocardiogram (ECG) and lidocaine's influence to the cardiac rhythm were observed and recorded during the main process of operation. RESULTS: Observation before and during the operation showed that mean arterial pressure (MAP) and heart rate (HR) decreased a little but within clinical acceptable range, at the beginning, and it recovered soon. The result of rate-pressure product (RPP) showed that the reduction of cardiac muscle oxygen consumption was satisfactory. There was no significant change in ST-segment in ECG (P>0.05) before and during the main procedure. Giving 1 mg/kg lidocaine before the operation could obviously lower the possibility or degree of premature ventricular extrasystole. CONCLUSION: OPCABG can be performed safely under the above method of anesthesia. The perioperative management is effective and satisfactory in maintaining stable circulation and in keeping oxygen supply and consumption balance.
