Urgent Dialysis Indications

Introduction to Urgent Dialysis

The European Renal Association recommends urgent dialysis in patients with severe hyperkalemia (>6.5 mEq/L) or persistent hyperkalemia (>5.0 mEq/L) that does not respond to medical treatment, even without evident symptoms 1

Urgent dialysis is indicated in patients with severe metabolic acidosis refractory to medical treatment, as stated by the European Society of Nephrology 1
The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines suggest that patients with volume overload that does not respond to diuretic therapy may require urgent dialysis 1
Patients with severe and progressive hyperphosphatemia (>6 mg/dL) may require urgent dialysis, according to the European Renal Association 1
Symptomatic severe hypocalcemia is an indication for urgent dialysis, as per the recommendations of the European Society of Nephrology 1
Patients with manifest uremic symptoms, including pericarditis and severe encephalopathy, require urgent dialysis, as recommended by the European Renal Association 1
Patients with elevated serum creatinine and persistent hyperkalemia (>5.0 mEq/L) unresponsive to medical therapy, or severe hyperkalemia (>6.5 mEq/L) without symptoms, require emergent hemodialysis, as recommended by the American Heart Association 1

Hemodialysis is the most rapid method for correcting severe electrolyte disturbances, as recommended by the European Society of Nephrology 1
Continuous renal replacement therapies (CRRT) are indicated in patients who are hemodynamically unstable, according to the European Renal Association 1
Peritoneal dialysis is a less efficient option for urgent solute removal but may be considered when other modalities are not available, as stated by the International Society of Peritoneal Dialysis 1

Monitoring of potassium levels to avoid overcorrection is crucial in patients undergoing urgent dialysis, as recommended by the National Kidney Foundation 1
Continuous electrocardiographic monitoring is recommended in patients with severe hyperkalemia, as per the American Heart Association guidelines 1
Vigilance for other electrolyte disturbances (calcium, phosphorus) is necessary in patients undergoing urgent dialysis, as recommended by the European Renal Association 1
Medications for hyperkalemia management include:

Patients with tumor lysis syndrome require daily frequent dialysis due to the continuous release of potassium and other metabolites, as recommended by the European Society of Nephrology 1
Patients with chronic kidney disease stage 5 (eGFR <15 mL/min/1.73m²) are at highest risk for dangerous hyperkalemia, according to the American Heart Association 2
Small elevations in serum creatinine (up to 30%) with RAS blockers should not be confused with acute kidney injury, as stated by the American Diabetes Association 3
Not all increases in serum creatinine represent actual kidney injury; some medications (e.g. trimethoprim, cimetidine) can cause false elevations, according to the European Renal Association 4
