OBJECTIVE: Kidney dysfunction is a major complication in the postoperative cardiac surgery setting. Operative risk factors for its development are cardiopulmonary bypass, anemia, antifibrinolytic drugs and blood transfusion. The objective of this study was to identify the risk factors for developing kidney dysfunction in patients undergoing cardiac surgery. METHODS: Ninety-seven patients were studied and 84 were analyzed. The sample was stratified into two groups. A serum creatinine higher than 30% compared to the preoperative period was considered for the kidney dysfunction group (n=9; 10.71%). There also was a control group when the increase in serum creatinine remained lower than 30% (n=75; 89.28%). RESULTS: It was observed that intraoperative transfusion of fresh frozen plasma in the control group was 2.05 ± 0.78 units and 3.80 ± 2.16 units in the kidney dysfunction group with P= 0.032. CONCLUSION: It was possible to associate that fresh frozen plasma transfusion is a risk factor for postoperative kidney dysfunction after cardiovascular surgery.
