ABSTRACT
POTASSIUM CHLORIDE • Potassium chloride (KCl) (10-20 mEq/kg
by IV bolus) is an alternative euthanasia drug. The KCl overdose induces cardiac arrest by mimicking hyperkalemia, resulting in myocardial conduction blockage, cardiac arrhythmias (bradycardia, tall T-waves, prolonged Q-T interval, cardiac standstill), and eventually cardiac fibrillation.
