【Abstract】 Objective To evaluate the value of a large dosage of fentany1 adminstration intravenously for coronary artery bypass graftingc (GABG) surgery. Methods 10 patients with coronary heart disease were scheduled for CABG under cardiopulmonary bypass and anesthesized mainly with a large dosage of fentany1.During anesthesia, MAP,HR,RPP were maintained at levels of 90～120 mmHg,50～60 bPm/min and <12 000,respectively. For myocardial protection, the hearts were perfused with cold crystal cardioplegia contained with postassium. Positive intropic and coronary artery-dilated medicines were used after the heart rebeat.Results After operation, no complications were found and ECG of 6 cases showed that myocardial ischemia had been improved.Conclusion Anesthesia with large dosage of fentanyl injected intravenously is a effective way for CABG surgery.更多还原
