41 HYPOKALEMIA General Discussion Hypokalemia is defined as a serum potassium level less than 3.6 mEq per liter. Hypokalemia has been associated with an increased risk of hypertension, ischemic stroke, hemorrhagic stroke, dysrhythmias, and hospital admissions and deaths due to heart failure and cardiovascular events. Hypokalemia primarily affects the cardiac, skeletal muscle, gastrointestinal, and renal organ systems. However, patients with hypokalemia are usually asymptomatic. Vague symptoms of fatigue and muscle weakness may be reported. The etiology of hypokalemia falls into three broad categories: insufficient potassium intake, transcellular shift of potassium from the extracellular to intracellular compartments, or excessive potassium loss. Diuretics are the most common drug-related cause of hypokalemia. Potassium loss via the gastrointestinal tract, usually as a result of diarrhea, is the second most common cause of hypokalemia in developed countries. Inadequate potassium intake is rarely a cause of hypokalemia. Medications Associated with Hypokalemia Albuterol Amphotericin B Carbenicillin Cisplatin Fludrocortisone Foscarnet Gentamicin Hydrocortisone Loop diuretics • Bumetanide • Furosemide • Torsemide Penicillin Theophylline Thiazide diuretics • Hydrochlorothiazide • Metolazone Verapamil overdose Causes of Hypokalemia ACTH-producing bronchogenic tumor Alcoholism Barium poisoning Bartter’s syndrome Caffeine intake Only gold members can continue reading.
