Abstract:
Objective To investigate the correlation of possible risk factors with acute renal injury (AKI) after coronary artery bypass surgery (CABG) and explore if the incidence of AKI could be lower by off-pump CABG for kidney protection.Methods Two hundred and nine patients who underwent coronary artery bypass surgery in Nanjing First Hospital from September 2010 to November 2013 were recruited.The patients were divided into AKI group (fifty-five cases) and non-AKI group (one hundred and fifty-four cases) according to the AKI criteria and compared the possible risk factors between two the groups by univariate analysis and multivariate analysis.Results The index of female gender,body mass index,age,hypertension,basic serum creatinine,ejection fraction,the number of coronary atherosclerosis,cardiopulmonary bypass,IABP for circulatory support,postoperative low cardiac output,lactate in AKI group were higher than that in non-AKI group by univariate analysis (P ＜ 0.05).And basic serum creatinine,ejection fraction,cardiopulmonary bypass,postoperative low cardiac output showed a significantly statistical difference between two group by multivariate analysis.Conclusions Cardiopulmonary bypass,basic serum creatinine,ejection fraction,postoperative low cardiac output were independent risk factors.Off-pump CABG could benefit for kidney protection.
