Abstract:

Objectives: This study aims to investigate the association between blood transfusion and acute kidney injury (AKI) in diabetic coronary artery bypass grafting (CABG) patients. Patients and methods: Between October 2016 and September 2019, a total of 270 elective CABG patients with diabetes (62 males, 208 females; mean age: 63.2±9.3 years; range, 40 to 86 years) were retrospectively analyzed. The patients were divided into two groups according to presence of cardiac surgery-related AKI. Risk factors were compared between the groups. Results: No significant difference was found between the groups in terms of baseline characteristics, except for body mass index, EuroSCORE II, and platelet count. The significant factors in the univariate analysis were included in the logistic regression. Only blood transfusion was found to be associated with AKI with red blood cell, fresh frozen plasma, platelet, and complete transfusions (p<0.001, p<0.001, p=0.002, and p<0.001, respectively). Conclusion: Our study results suggest that perioperative red blood cell, fresh frozen plasma, platelet, and complete transfusions are associated with postoperative AKI in diabetic CABG patients.
