Abstract:
Objective:To identify the risk factors for postoperative acute kidney injury (AKI) in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:The medical records of patients who underwent elective OPCABG from January 1, 2018 to December 31, 2020 from the Heart Center of Henan Provincial People′s Hospital, were retrospectively collected.The patient′s gender, age, body mass index, history of diabetes, history of hypertension, history of hyperlipidemia, history of chronic obstructive pulmonary disease, history of cerebrovascular disease, history of myocardial infarction, New York Heart Association classification of cardiac function, Killip classification, values of last left ventricular ejection fraction measured by transthoracic echocardiography before operation, glycosylated hemoglobin, glucose and serum creatinine, duration of operation, intraoperative fluid intake and output such as red blood cell infusion, crystal fluid, colloid fluid, autologous blood, blood loss and urine volume, intraoperative hypotension, perioperative maximal blood glucose difference (MGD) and serum creatinine concentrations within 48 h and 7 days were recorded.Postoperative AKI was defined according to the Kidney Disease Improving Global Outcomes criteria and the patients were divided into AKI group and non-AKI group according to whether AKI occurred after surgery.Logistic regression analysis was used to identify the risk factors for AKI after OPCABG.Results:A total of 1 203 patients were included in this study, and the incidence of AKI after OPCABG was 28.1%.Logistic regression analysis showed that body mass index, history of hypertension and perioperative MGD were risk factors for AKI after OPCABG ( P<0.05). Conclusion:Body mass index, history of hypertension and perioperative MGD are risk factors for AKI after OPCABG.
