RESUMO
INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) and Continuous renal replacement therapy (CRRT) are treatments for critically ill patients with respiratory failure and acute kidney injury. However, no reliable factors have been identified to predict survival in patients treated with both ECMO and CRRT. The aim of this study was to identify prognostic factors for discharging intensive care unit (ICU) patients who required CRRT during ECMO. METHODS: We retrospectively analyzed data from patients who required CRRT in addition to the ECMO, between April 2015 and March 2018. The patients were divided into two groups: patients who survived and patients who died during ICU hospitalization. We determined their demographic and clinical characteristics, Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, Simplified Acute Physiology Score II (SAPS II) scores, and sequential organ failure assessment (SOFA) scores. Further, we assessed whether these characteristics differed between individuals who did or did not survive the ICU hospitalization. RESULTS: We found that the APACHE II and SAPS II scores differed significantly between both ECMO and CRRT treated patients who did or did not survive hospitalization. Further, intracranial hemorrhage during ECMO and CRRT therapy was associated with lower survival rate. CONCLUSIONS: Using APACHE II and SAPS II scores might be helpful in making treatment decisions for patients treated with ECMO and CRRT. Intracranial hemorrhage could be a poor prognostic factor. Our findings indicate the potential utility of APACHE II and SAPS II scores to predict mortality in patients treated with both ECMO and CRRT.
