MO861THE PROGNOSIS OF PATIENTS RECEIVING CONTINUOUS RENAL REPLACEMENT THERAPY (CRRT) AFTER CARDIOVASCULAR SURGERY DEPENDS ON THE INDICATION FOR ITS INITIATION

Abstract Background and Aims Continuous Renal Replacement Therapy is required in 2.6% to 5% of patients who have undergone cardiovascular surgery. Although its implementation is frequent, several aspects of this therapeutic measure still remain uncertain. Method The data of all patients who were surgically treated during a 3-year period (2017-2019) at a single cardiovascular department were collected and the cases in which continuous renal replacement therapy was used were identified. From this group, the data of those that received dialysis for the first time were analyzed. Results In about 5% of patients renal replacement was inevitable, and the mortality rate among them reached 57.6%. The mean duration of renal therapy was 8.4 days. The investigation of laboratory parameters in different stages revealed certain aspects about the expected outcomes. The survival rate varied significantly in relation to the indication for CRRT. Fluid overload and electrolytic disorders were associated with high survival rate, while oliguria or anuria, acidosis or intoxications were linked to increased mortality rate. Conclusion Despite CRRT being associated with high mortality rates, it is the only option for life-threatening conditions in clinical practice. The indication for CRRT is a key factor for the prognosis, decision-making and the overall management of a patient.
