Abstract

Background:To define acute kidney injury (AKI) that develops following coronary artery bypass grafting (CABG) surgery using RIFLE classification system and to determine the risk factors affecting the early and late mortality of the patients who developed acute kidney injury.Materials and Methods: A total of 213 patients who underwent isolated CABG operation in our clinic between February 2016 and September 2018 were retrospectively investigated. Preoperative and postoperative estimated glomerular filtration rates were calculated for all patients. The diagnosis and severity of AKI was determined by RIFLE classification.Results: The median age of the patients included in the study was 62, of whom 114 were male. In the postoperative period, AKI was detected in 65 (30.5%) patients according to RIFLE classification. 63.1 % of the patients were in stage R, 23.1 % were in stage I, 13.8 % were in stage F. L and E stages of AKI did not develop in any patients. Comorbid conditions such as diabetes mellitus, hypertension, congestive heart failure and peripheral artery disease, and the duration of cardiopulmonary bypass (CPB) were detected to be independent risk factors for the development of AKI. Bleeding revision need for hemodialysis, usage of intra aortic balloon pump and respiratory complications were higher in the AKI group than in the non-AKI group. In addition, in-hospital and long term mortality rates were significantly higher in AKI group. As the severity of AKI increased, the survival rates of the patients were decreased. The patients in stage –F had the lowest survival rate. Conclusion: RIFLE classification is a low-cost and easy-to-use tool to detect AKI developing after CABG surgery and it helps to detect kidney injury at the initial stage. This classification provides a prediction about the mortality and morbidity of the patients who developed AKI following CABG surgery.

Özet

Amaç: RIFLE sınıflamasını kullanarak Koroner arter bypass greftleme (KABG) cerrahisi sonrasında gelişen akut böbrek hasarını (ABH) tanımlamak, hasar gelişmiş hastaların erken ve geç dönem mortalitelerine etki eden risk faktörlerini belirlemektir.Materyal ve Metod: Kliniğimizde Şubat 2016 ile Eylül 2018 yılları arasında izole KABG operasyonu yapılan 213 hasta geriye dönük olarak incelendi. Tüm hastaların operasyon öncesi ve sonrası tahmini glomeruler filtrasyon hızları hesaplandı. ABH’nin tanısı ve ciddiyeti, RIFLE sınıflaması ile belirlendi. Bulgular: Çalışmaya dâhil edilen hastaların medyan yaşı 62 yıldı, hastaların 144’ü (%67,6) erkekti. Postoperatif dönemde, RIFLE sınıflamasına göre 65 (%30,5) hastada ABH saptandı. Hastaların %63,1’i evre R, %23,1’i evre I, %13,8’i ise F evresindeydi. ABH’nin L ve E evresi hiçbir hastada gelişmedi. Diyabetes mellitus, hipertansiyon, konjestif kalp yetmezliği, periferik arter hastalığı gibi komorbid faktörler ve kardiyopulmoner bypass (KPB) süresi ABH gelişiminde bağımsız risk faktörleri olarak saptandı. ABH bulunan grupta ABH bulunmayan gruba göre post operatif dönemde kanama revizyonu, hemodiyaliz ihtiyacı, intraaortik balon pompası kullanımı ve solunumsal komplikasyonlar daha fazlaydı. Ek olarak, hastane içi ve geç dönem mortalite oranları ABH olan grupta daha yüksekti. Hastaların sağkalım oranları ABH’nin ciddiyeti arttıkça düştü. Evre F’deki hastalar en düşük sağkalım oranına sahipti. Sonuç: RIFLE sınıflaması, KABG cerrahisi sonrası gelişen ABH’yi gösteren maliyeti düşük ve kolay uygulanabilir bir araçtır ve böbrek hasarının başlangıç evresinde saptanmasına yardımcı olur. Bu sınıflama, KABG cerrahisi sonrası ABH gelişen hastaların mortalite ve morbiditesi hakkında öngörü sağlar.
