ФАКТОРЫ РИСКА И ИСХОДЫ ОСТРОГО ПОЧЕЧНОГО ПОВРЕЖДЕНИЯ В РАННЕМ ПЕРИОДЕ ПОСЛЕ КАРДИОХИРУРГИЧЕСКИХ ОПЕРАЦИЙ

Aim. To assess the rate of acute kidney injury (AKI) development, incl. the necessity of renal replacement therapy (RRT), to evaluate the risk factors and outcomes of AKI. Material and methods. In the study, 2958 patients included, after a variety of cardiosurgical operations. The stage of AKI and indications for RRT were set based on the criteria of Kidney Disease: Improving Global Outcomes. Results. The rate of AKI development in general was 14%. AKI 1 stage was diagnosed in 10,2% (n=303), stage 2 in 3% (n=88) and stage 3 in 0,8% (n=23). RRT was implemented in 1,3% (n=38) of patients. The rate of AKI development post single coronary bypass (CBG) was 9,5% (n=35), single valve replacement (VR) and/or valve plastics (VP) — 19,8% (n=35), CBG+VR+VP — 33% (n=84), combination operations — 19,5% (n=107). Necessity of RRT post CBG — 0,3% (n=6), post VP/ VR — 0,56% (n=1), post CBG+VR/VP — 5,5% (n=14), post combination surgeries — 3% (n=17). Conclusion. The risk factors for AKI: age, body mass index, left atrium volume index, surgery type, the syndrome of low cardiac output, atrial fibrillation in early post operation period, inotropic and vasopressory support, lactat-acidosis. Development of AKI does prolong hospitalization time and increase mortality.
