Abstract:
Objective To explore and analysis feasibility of the prevention of edaravone on myocardial ischemia after beating cor-onary artery bypass grafting .Methods From June 2011 to December 2012 ,78 patients which accepted beating heart coronary artery bypass grafting were randomly divided into treatment group (39 cases) and control group(39 cases) .After induction of anesthesia , the treatment group were continued to intravenous edaravone 60 mg ,while the control group were continued infusion of equivalent saline .The serum superoxide dismutase(SOD) ,malondialdehyde(MDA) levels were compared between the two groups at different times which were before surgery (T1) ,after incision 1 h(T2) ,surgery (T3) ,and after 24 h(T4) ,plasma brain natriuretic peptide (BNP) ,troponin I(cTnI) levels were compared at T1 and T4 .Left ventricular ejection fraction(LVEF) were also be compared .Re-sults The two groups of patients before treatment ,there were not statistically significant difference between the two groups on SOD ,MDA ,CK-MB ,BNP and cTnI(P> 0 .05) .At T2 ,T3 ,T4 point ,the SOD activity of the treatment group was significantly higher than that of control group(P<0 .05) .The MDA ,CK-MB value were significantly lower than that of control group (P<0 . 05) .At T4 ,the BNP and cTnI in the treatment group were less than that of control group (P<0 .05) .The postoperative LVEF% in treatment group were significantly higher than that of control group (P<0 .05) .Postoperative ventilator treatment time and ICU stay time and total hospitalization time of the treatment group were all significantly less than that of control group (P<0 .05) .Con-clusion For the beating heart coronary artery bypass surgery patients ,edaravone can effectively scavenge oxygen free radicals and reduce the release of enzymes ,reduce injury caused by myocardial ischemia-reperfusion and protect myocardial cells .
