Analysis of the risk factors acute kidney injury after off-pump coronary artery bypass surgery / 国际外科学杂志

ABSTRACT

Objective Univariate analysis and multivariate risk factors of early acute kidney injury on off-pump coronary artery bypass grafting are performed.Methods Analyzed retrospectively the clinical date of 261 patients who underwent off-pump coronary artery bypass surgery between Jan 2011 to Dec 2013.According to the clinical diagnostic ctriteria,261 patients were divided into AKI group (n =29) and NAKI group(n =232).There were 22 males and 7 females with an age of (68.74 ± 10.27) years in the AKI group,there were 179 males and 53 females with an age of (66.26 ± 9.82) years in the NAKI group.we summarize the clinical date,including blood pressure,left ventricular ejecting fraction,diameter of the left ventricle and serum creatinine before operation,and observed postoperative complications etc.Evaluated the factors for AKI Using Logistics regression analysis statistical methods.Results Among all the patients,the incidence of AKI was 11.11％ (29/261),1 patients died in all the patients for AKI.The statistical analysis revealed that the serum creatinine after operation,anesthesia time,and perioperative blood transfusion were the risk factors for acute injury after off-pump coronary artery bypass surgery.Conclusion AKI is the most common complication of off-pump coronary artery bypass surgery.we should carefully evaluate risk factors and enhance protection of the renal function and reduce the risk of AKI occurred.
