Abstract:
Objective To evaluate the effect of edaravone on myocardial injury in patients undergoing offpump coronary artery bypass grafting (OPCABG).Methods Forty ASA physical status Ⅲ-Ⅳ patients,aged 45-64 yr,weighing 55-95 kg,with NYHA class Ⅱ-Ⅲ,scheduled for elective OPCABG,were randomly divided into 2 groups (n =20):edaravone group (group E) and control group (group C).After induction of anesthesia,edaravone 60 mg (in 100 ml of normal saline) was infused over 30 min in group E,while the equal volume of normal saline was given instead of edaravone in group C.Venous blood samples were taken before operation (T1),after skin incision (T2),at the end of operation (T3),and at 24 h after operation (T4) to measure the serum levels of myocardial enzymes and cardiac troponin Ⅰ (cTnI).The time for ventilator treatment,duration of stay in the intensive care unit and duration of stay in hospital were recorded.Results Compared with group C,the activities of serum creatine kinase,creatine kinase isoenzyme-MB,aspartate aminotransferase and lactate dehydrogenase and cTnI concentrations were significantly increased at T3 and T4 (P ＜ 0.05) and no significant changes were found at T1 in group E (P ＞ 0.05).The parameters mentioned above were significantly higher at T3 and T4 than at T1 in the two groups (P ＜ 0.05).The time for ventilator treatment,duration of stay in the intensive care unit and duration of stay in hospital were significantly shortened in group E as compared with group C (P ＜ 0.05 or 0.01).Conclusion Edaravone 60 mg infused before OPCABG can provide effective myocardial protection in patients.
