ABSTRACT
Background: Renal damage and subsequent acute renal failure is one of the most important complications in patients who had cardiac surgery. Multicenter studies with thousands of patients which exposed the risk factors for acute renal failure has been published especially in the last decade. This study is designed for evaluation of heparin-coated and non-coated oxygenators on the renal functions. Methods: This study has been performed prospectively with 50 patients who had undergone coronary bypass surgery in our clinic from March 2006 to September 2006. The patients have been divided into two groups as non-coated oxygenators (n = 25, Group 1) used and heparin-coated oxygenators (n = 25, Group 2) used. Blood samples were collected at the preoperative, and at 1st, 24th and 96th postoperative hours. The demographic data were similar in two groups. Results: There was no early mortality in both groups. Operative and postoperative parameters were similar in both groups. There were no statistical differences between the evaluated parameters like BUN, creatinine, sodium, potassium, calcium, chloride, phosphorus, urine protein, creatinine clearence, urine sodium, urine calcium and urine chloride tests at preoperative period in both groups. We did not detect renal dysfunction in any patients. There are no statistical differences in the creatinine clearance in preoperative and postoperative periods in both groups. In group one, creatinin levels were lower than group two at 24 hours after surgery and these differences were statistically important in two groups. We found no significant difference between two groups regarding the other parameters for renal function during the postoperative period. Conclusion: In this study, there were not any significant difference between coated and non-coated oxygenators’ effects over renal functions of patients whose renal functions were normal preoperatively.
