Indications for Dialysis in Acute Kidney Injury (AKI)
1. Refractory Fluid Overload
2. Severe hyperkalemia (>6.5 mEq/L) or rapidly rising potassium levels
3. Signs of uremia including pericarditis, encephalopathy, or decline in mental status not explained by other abnormality/condition
4. Severe metabolic acidosis (pH<7.1)
5. Certain alcohol and drug intoxications
In patients with underlying chronic kidney disease (CKD), the likelihood of receiving dialysis increases in proportion to the decline in glomerular filtration rate (GFR) at baseline.
