Fluid Overload Associates With Major Adverse Kidney Events in Critically Ill Patients With Acute Kidney Injury Requiring Continuous Renal Replacement Therapy

Abstract

In critically ill patients with acute kidney injury requiring continuous renal replacement therapy, greater than 10% fluid overload was associated with higher risk of 90-day major adverse kidney events, including mortality and decreased renal recovery. Increased time between ICU admission and continuous renal replacement therapy initiation was also associated with decreased renal recovery. Fluid overload represents a potentially modifiable risk factor, independent of timing of continuous renal replacement therapy initiation, that should be further examined in interventional studies.
