CHARACTERISTICS OF ACUTE KIDNEY INJURY IN PATIENTS UNDERGOING OPEN-HEART SURGERY AT MILITARY HOSPITAL 103
Main Article Content
Abstract
Objectives: To evaluate characteristics of acute kidney injury (AKI) in patients undergoing open-heart surgery with cardiopulmonary bypass (CPB). Methods: A retrospective, descriptive case series, uncontrolled study was conducted on 231 patients who underwent open-heart surgery at Military Hospital 103 from June 2018 to October 2025. Results: A total of 231 patients were included, with a mean age of 58.4 ± 13.8. The incidence of AKI was 67.5%, of which 54.5% at stage 1, 11.7% at stage 2, and 1.3% at stage 3. Patients in the AKI group had significantly higher age, surgical risk scores, urea levels, aortic cross-clamp time, and CPB duration compared to the non-AKI group (p < 0.05). Furthermore, the AKI group exhibited poorer cardiac function, lower glomerular filtration rate, and required more red blood cell transfusions (p < 0.05. Conclusion: AKI is a common complication following open-heart surgery, primarily occurring at a mild stage of severity. However, it significantly increases treatment costs due to prolonged ICU and postoperative hospital stays.
