Management of Hyperkalemic Periodic Paralysis

Acute Management

The American College of Cardiology recommends administering intravenous calcium gluconate (10%): 15-30 mL IV over 2-5 minutes to stabilize cardiac membranes in severe episodes with significant weakness or ECG changes 1
Administering insulin with glucose can shift potassium into cells, with effects beginning within 15-30 minutes and lasting 4-6 hours, as recommended by the Mayo Clinic 1, 2
Beta-agonists (e.g., albuterol) can be used to promote intracellular potassium shift, according to Praxis Medical Insights 1
For patients with concurrent metabolic acidosis, sodium bicarbonate may be beneficial to promote potassium excretion, as suggested by the Mayo Clinic Proceedings 1, 2
In severe cases unresponsive to medical management, hemodialysis remains the most effective method for potassium removal, as stated in the Mayo Clinic Proceedings 2

The Mayo Clinic recommends loop or thiazide diuretics as first-line agents for chronic management to promote urinary potassium excretion 1, 3
Fludrocortisone can increase potassium excretion but carries risks of fluid retention, hypertension, and vascular injury, according to the Mayo Clinic Proceedings 3
Newer FDA-approved agents like patiromer and sodium zirconium cyclosilicate are preferred for long-term management, as recommended by the Mayo Clinic Proceedings and Praxis Medical Insights 1, 3

A team approach involving specialists, primary care physicians, and other healthcare professionals is necessary for optimal management, as recommended by Praxis Medical Insights 1
Regular monitoring of serum potassium levels, especially when starting new medications, is crucial, according to Praxis Medical Insights 1
Maintaining adequate hydration supports renal potassium excretion, as suggested by the Mayo Clinic Proceedings 3
