Abstract:Objective: To explore the effects of sevoflurane anesthesia and propofol anesthesia on hemodynamics, myocardial protection and adverse events in elderly patients with coronary heart disease undergoing non-cardiac surgery. Methods: A total of 132 elderly patients with coronary heart disease admitted to the hospital between September 2017 and September 2020 were selected as the research subjects, and they were simply randomly divided into sevoflurane group (n=66) and propofol group (n=66), and respectively given continuous inhalation of 3% sevoflurane and continuous infusion of 3 μg/ml propofol for anesthesia during non-cardiac surgery. The surgical status, myocardial markers, hemodynamic parameters and occurrence of cardiac adverse events and other adverse events were compared between the two groups. Results: The awake time, extubation time and transfusion volume of sevoflurane group were significantly shorter or less than those of propofol group (P<0.05). Immediate measure after surgery showed that the level of cardiac troponin I (cTnI) was significantly lower in sevoflurane group than that in propofol group (P<0.05). The levels of cTnI and creatine kinase-MB (CK-MB) in sevoflurane group at 12h and 24h after surgery were significantly lower than those in propofol group (P<0.05). At T1, the SBP of sevoflurane group was significantly higher compared to propofol group (P<0.05). At T2, the heart rate (HR) of sevoflurane group was significantly lower than that of propofol group while the systolic blood pressure (SBP) was significantly higher than that of propofol group (P<0.05). At T3, the SBP was significantly higher in sevoflurane group compared with that in propofol group (P<0.05). At T4, the HR of sevoflurane group was significantly lower while the SBP and diastolic blood pressure (DBP) were significantly higher compared to propofol group (P<0.05). At T5, the SBP and DBP in sevoflurane group were significantly higher than those in propofol group (P<0.05). The total incidence rate of adverse cardiac reactions was 10.61% in sevoflurane group, which was significantly lower than 28.79% in propofol group. The total incidence rate of other adverse reactions in sevoflurane group was significantly higher than that in propofol group (19.70% vs 6.06%) (P<0.05). Conclusion: Sevoflurane for anesthesia has a more stable hemodynamic effect and shorter anesthesia time and recovery time in elderly patients with coronary heart disease undergoing non-cardiac surgery, and it better protects the myocardium and has less transfusion volume and lower incidence of cardiac adverse events. But it is prone to adverse events such as nausea and vomiting, thus it is suitable for patients with fear of injections, potential airway difficulties and heart risks.
