A 2026 Canadian Veterinary Journal article reviewed emergency management of hyperkalemia in dogs and cats, with Part 1 focusing on pathophysiology and etiology.
Three quick summaries of the same article, tailored for different readers.
Owners will usually not know a pet’s potassium level at home, but they can recognize scenarios where it matters: a male cat straining to urinate, collapse, severe weakness, shock, or known kidney or adrenal disease with worsening signs. These are not wait-and-see problems. Hyperkalemia can affect the heart’s rhythm.
Useful source for a timely veterinary news/research update and audience-specific teaching context.For vet techs, suspected hyperkalemia should sharpen triage. Ask about urinary obstruction, renal disease, Addison’s disease, collapse, bradycardia, weakness, and recent fluids or medications. Monitor ECG when directed, repeat vitals, and escalate bradyarrhythmias, collapse, or worsening mentation quickly.
Useful source for a timely veterinary news/research update and audience-specific teaching context.For pre-vet readers, hyperkalemia links physiology to emergency medicine. Increased extracellular potassium reduces the resting membrane potential gradient, altering excitability and conduction. Differential priorities include postrenal obstruction, renal failure, hypoadrenocorticism, severe tissue injury, acidosis, and sample artifacts. The board-style trap is treating it as “just renal” without considering ECG risk and obstruction.
