Managing Volume Overload in Anuric AKI
Introduction to Volume Overload Management
- The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines suggest not using diuretics to treat AKI, except in the management of volume overload, with a strength of evidence of 2C 4, 5, 6
- A cumulative positive daily fluid balance in patients who develop AKI is associated with significantly higher mortality rates 1, 2
Volume Overload Consequences
- Fluid accumulation can lead to pulmonary edema and respiratory compromise 3
- Increased intra-abdominal pressure due to fluid accumulation can further compromise renal perfusion 3
Evidence-Based Management Approaches
- The KDIGO guidelines recommend using isotonic crystalloids rather than colloids for initial volume expansion in patients with AKI 4, 6
- Avoid starch-containing fluids as they have been associated with harm in patients with AKI 4, 6
- In hemodynamically stable, volume-overloaded patients with AKI, furosemide can be used to manage fluid overload 1, 2
- Higher furosemide doses have shown a protective effect on mortality in AKI patients with volume overload 1, 2
Special Considerations
- In patients with liver disease and AKI, albumin administration (1 g/kg/d up to 100 g/d) may be beneficial 4, 6, 3
- Albumin has shown benefit in preventing renal failure and death in patients with spontaneous bacterial peritonitis 4, 6
