Anesthetic management experience of 20 cases of coronary artery bypass grafting

Objective To summarize the clinical effect of coronary artery bypass grafting.Methods In 20 patients undergoing elective coronary artery bypass grafting,sufentanil anesthesia was the main method,and propofol and midazolam were selected to protect myocardial function,and sevoflurane intravenous inhalation was combined to maintain intraoperative sedation.The changes of blood pressure index,heart rate and bispeetral index(BIS)before and after anesthesia were compared.Results After anesthesia,the systolic blood pressure(112.36±3.36)mm Hg(1 mm Hg=0.133 kPa)and diastolic blood pressure(63.36±3.25)mm Hg were lower than(150.52±2.25)and(90.25±2.25)mm Hg before anesthesia,and the difference was statistically significant(P<0.05).After anesthesia,the heart rate(69.02±0.58)beats/min and BIS(42.36±1.36)were lower than(98.12±0.26)beats/min and(86.36±3.36)before anesthesia,and the difference was statistically significant(P<0.05).Conclusion The primary task of anesthesia surgery should be to prevent myocardial hypoxia and ischemia and prevent cerebral ischemia and hypoxia.So we should ensure sufficient oxygen supply before anesthesia,maintain sedation,strive to maintain stable hemodynamics during anesthesia,and properly use vasodilators during perioperative period to reduce cardiac load.
