ABSTRACT

Introduction: Acute renal dysfunction is one of the most serious complications of the critical patient, has a high incidence of more than 55% and a mortality of around 40%. Continuous renal replacement therapies are extracorporeal support methods that replace the glomerular filtration function continuously. Methods. A retrospective and observational study was performed in patients with acute renal dysfunction treated with renal replacement therapy, admitted to the intensive care service of the Surgical Medical Research Center in the period from January 2015 to September 2019. The risk factors associated with mortality and recovery of renal function were studied. Results. 126 patients were studied; The main risk factors associated with acute renal failure were sepsis (85,7%) and arterial hypotension (95,2%). The overall mortality in the intensive care unit was 59,5%, the main cause of death being the multi-organ failure. The most affected systems were cardiovascular (95,2%) and respiratory (69%). The mean Sepsis-related Organ Failure Assessment score was 12 ± 2,5. Of the survivors upon discharge from the intensive care unit, it stands out that only 13,7% were left with intermittent hemodialysis dependence. The factors most related to the recovery of renal function were creatinine at admission and the presence of anuria. Conclusions. The mortality of critical patients treated with renal replacement therapy is still high. Oliguric and traumatic patients had better survival. Age over 60 years and the Sepsis-related Organ Failure Assessment score over 11 points were independent risk factors for mortality.
