ABSTRACT
Objective To investigate the prognostic effects of continuous renal replacement therapy on multiple organ dysfunction complicated with acute kidney injury.Methods Fifty nine patients who were diagnosed with multiple organ dysfunction syndrome (MODS) complicated with acute kidney injury (AKI) and underwent continuous renal replacement therapy (CRRT) were selected and grouped according to the Kidney Disease Improving Global Outcomes (KDIGO) staging.Their clinical data before CRRT were collected.The patients were grouped according to the Intensive Care Unit (ICU) prognosis,namely death and survival.The differences between two groups were analyzed.The multinomial logistic regression analysis was performed to explore the prognostic factors.Results With the increase of KDIGO stage,the Acute Physiology And Chronic Health Evaluation Ⅱ (APACHEII) score,Sequential Organ Failure Assessment (SOFA) score,the need for vasoactive drugs,and the number of cases with oliguria and ICU mortality rates showed an increasing trend,and those differences were statistically significant (P ＜ 0.05).After multivariate analysis,KDIGO Ⅲ stage,the number of failed organs,oliguria,and the mean daily fluid balance were independent risk factors of death in patients who were diagnosed with MODS complicated with AKI and underwent CRRT.Conclusions The KDIGO classification plays an important role in predicting the prognosis of patients with MODS complicated with AKI in need of CRRT.The number of failed organs,oliguria,and the mean daily fluid balance are also the risk factors for prognosis.
