Application of different anesthetic methods in coronary artery bypass grafting and its effect on postoperative outcome were explored. Ninety-four patients undergoing coronary artery bypass grafting in Jining No. 1 People's Hospital from March 2017 to February 2018 were randomly divided into the control and observation groups. The control group was anesthetized by fentanyl and propofol. The observation group was anesthetized by sevoflurane combined anesthesia. The mean heart rates (HR), mean arterial pressure (MAP), systemic vascular resistance index (SVRI) and cardiac index (CI) in the two groups were compared. The levels of β endorphin (β-EP) and malondialdehyde (MDA) in patients were examined. Adverse reactions in the two groups were compared. The enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of serum inflammatory factors. The prognosis of the two groups was analyzed and compared. MoCA and MMSE scale were used to evaluate postoperative cognitive function in the two groups. The levels of β-EP and MDA in the two groups during operation were higher than those before operation (P&lt;0.05). On the third, fifth and seventh day after operation, the CRP, TNF-α and IL-6 levels of the two groups increased significantly compared to those before operation (P&lt;0.05). The eating time and out of bed time in the observation group were significantly earlier than those in the control group, and the length of stay in the observation group was significantly shorter than that in the control group (P&lt;0.05). On the first day after operation, the scores of MoCA and MMSE in the observation group were better than those in the control group (P&lt;0.05). The two different anesthetic methods can maintain the perioperative hemodynamic stability of coronary artery bypass patients, but sevoflurane intravenous-inhalation combined anesthesia can effectively adjust the β-EP in the body, and reduce the oxidative stress response, which is favorable for postoperative outcome.
