From the Guidelines
Treatment for hyperkalemia with a potassium level of 6.1 mEq/L requires prompt intervention, starting with calcium gluconate 10% (10 mL IV over 2-3 minutes) to stabilize cardiac membranes if ECG changes are present, as recommended by the most recent guidelines 1. To manage hyperkalemia effectively, it's crucial to assess for ECG changes and symptoms like muscle weakness or palpitations. The initial management includes:
- Calcium gluconate to stabilize cardiac membranes
- Insulin (10 units regular insulin IV) with glucose (25-50g IV) to shift potassium into cells and prevent hypoglycemia
- Consideration of albuterol nebulization (10-20 mg) to further promote potassium shift into cells For potassium removal, options include:
- Sodium polystyrene sulfonate (15-30g orally or 30-50g rectally)
- Loop diuretics like furosemide (40-80mg IV) if kidney function is adequate In severe cases or with poor kidney function, hemodialysis may be necessary. It's essential to identify and address the underlying cause, such as medication effects, kidney dysfunction, or acidosis, as highlighted in the European Society of Cardiology guidelines 1. Close monitoring of potassium levels, ECG, and glucose is critical during treatment, with adjustments made as necessary to ensure patient safety and effective management of hyperkalemia.

From the Research
Treatment for Hyperkalemia
The treatment for hyperkalemia (elevated potassium level) of 6.1 involves several measures to stabilize cardiac membranes, shift potassium from extracellular to intracellular stores, and promote potassium excretion 2.
- Membrane Stabilization: Calcium gluconate 10% dosed 10 mL intravenously should be provided for membrane stabilization, unless the patient is in cardiac arrest, in which case 10 mL calcium chloride is warranted 2.
- Cellular Shift: Beta-agonists and intravenous insulin should be given to shift potassium from extracellular to intracellular stores 2.
- Potassium Excretion: Dialysis is the most efficient means to enable removal of excess potassium 2. Loop and thiazide diuretics can also be useful 2.
- New Medications: New medications to promote gastrointestinal potassium excretion, which include patiromer and sodium zirconium cyclosilicate, hold promise 2, 3, 4.
- Sodium Polystyrene Sulfonate: Sodium polystyrene sulfonate is not efficacious 2 and its use is associated with serious gastrointestinal adverse effects 3. However, some studies suggest that it may reduce serum potassium levels, although the treatment effect may not be clinically important 5.
Dosage and Administration
The dosage and administration of these treatments may vary depending on the patient's condition and the severity of hyperkalemia. For example, the dose of sodium polystyrene sulfonate can range from 15 to 30 g orally 5.
Clinical Considerations
It is essential to consider the underlying cause of hyperkalemia and to address it accordingly 3, 6. The treatment of hyperkalemia should be individualized based on the patient's clinical presentation, laboratory results, and medical history 4, 6.
