Abstract:
Objective To determine the risk factors for postoperative acute kidney injury (AKI) in the patients undergoing cardiac transplantation.Methods Forty patients with end-stage heart failure (both sexes) , aged 13-66 yr, weighing 45-84 kg, of ASA physical status Ⅳ or Ⅴ (NYHA Ⅲ or Ⅳ), undergoing heart transplantation, with normal kidney function before operation, were selected.According to whether or not AKI occurred within 7 days after operation, the patients were divided into either AKI group or non-AKI group.Factors including age, gender, body weight, complications (including hypertension and diabetes mellitus), preoperative blood glucose, hemoglobin, serum creatinine, cardiac output, ejection fraction, pulmonary arterial systolic pressure, intraoperative cardiopulmonary bypass (CPB) time, transfusion of allogeneic red blood cells, and urine volume within 24 h after operation were recorded.The risk factors of which P values were less than 0.05 would enter the multivariate logistic regression analysis to stratify postoperative AKI-related risk factors for this type of patients.Results A total of 39 patients were enrolled in this study.Of the 39 patients, 14 patients suffered from AKI after operation, and the incidence was 36％.The results of logistic regression analysis showed that preoperative pulmonary hypertension and CPB time ＞ 180 min were the independent risk factors for AKI after cardiac transplantation.Conclusion Preoperative pulmonary hypertension and CPB time＞180 min are the independent risk factors for postoperative AKI in the patients undergoing cardiac transplantation.
