A Curbsiders classic with a fresh intro by Hannah Abrams @hannahRabrams (soon to be MD)! Master the management of hyperkalemia with tools, tips and tactics from @kidney_boy, Joel Topf MD, Chief of Nephrology @KashlakHospital. We cover: common causes of hyperkalemia; the U-shaped curve of potassium levels and mortality; albuterol nebs; how to safely use insulin; potassium binding resins and colonic necrosis; Does it make sense to give loop diuretics and fluids?; Should we be using fludrocortisone?; Plus, answers to all your questions about a high potassium diet and oral potassium supplements! Join us for Dr Topf’s masterful insights on hyperkalemia and potassium homeostasis. Get deeper into potassium physiology with a FREE pdf copy of Joel’s book The Fluid Electrolyte and Acid Base Companion here.
