Açık kalp ameliyatı geçiren ileri yaştaki hastalarda akut böbrek hasarı için risk faktörleri

Abstract: Objective: Our studys goal is, to determine the risk factors for acute kidney injury in octogenarians undergoing open-heart surgery to decrease mortality and morbidity by enhancing accurate patient selection in the preoperative period. Materials and Method: Between January 2017-December 2022, 678 patients analyzed retrospectively. The patient groups were divided as follows: < 70 years old = control group, 70–80 years old = septuagenarian group, and > 80 years old = octogenarian group. Age, sex, ethnicity, Euroscore, preoperative serum creatinine levels, postoperative first-month serum creatinine levels, dialysis requirements, and first-year mortality parameters were analyzed. Results: 206 patients has included into study, with 94 patients in the control group (79 male), 29 patients in the septuagenarian group (22 male), and 83 patients in the octogenarian group (70 male). There was a statistically significant difference between the groups based on preoperative serum creatinine. Of the 26 patients requiring renal replacement therapy, 6 were in the control group, 3 were in the septuagenarian group, and 17 were in the octogenarian group. There was a statistically significant difference between groups based on requiring renal replacement therapy, and 11 of the patients requiring renal replacement therapy died. Of the 22 patients who died overall, 4 were in the control group, 3 were in the septuagenarian group, and 15 were in the octogenarian group. Conclusion: In the senior patient group, the best approach for optimal patient selection is to ensure meticulous surgical technique and myocardial protection.
