ONE of the most common disorders encountered in clinical medicine is abnormal potassium metabolism resulting in either hyperkalemia or hypokalemia. In a healthy person, potassium balance is a function of oral intake and renal excretion. On a normal daily oral intake of 40 to 100 mEq, the urinary potassium excretion varies between 40 and 90 mEq/24 hr ...

Potassium is the principal intracellular cation, and maintenance of the distribution of potassium between the intracellular and the extracellular compartments relies on several homeostatic mechanisms. When these mechanisms are perturbed, hypokalemia or hyperkalemia may occur.

Pseudohyperkalemia, or factitious hyperkalemia, constitutes an artificially high plasma potassium level (P(K)) from a variety of possible causes. Occasionally, the cause cannot be elucidated. Three patients who showed unusually large differences between free-flowing and tourniquet (stasis) potassium levels prompted us to investigate the influence of ...

Hyperkalemia in Hemodialysis Patients
Seminars in Dialysis, 2014Hyperkalemia contributes significantly to high mortality among ESRD patients. Excess intake and inadequate removal are the most common etiologies in HD patients. Although dialysis is the definitive treatment, classical medical therapy must be employed as a temporizing measure to acutely lower serum potassium.

Pediatrics In Review, 1996
Potassium is the major intracellular cation; only a very small fraction of total body potassium is in the intravascular space. Increased potassium concentration in serum is infrequent in pediatrics, but it can be life-threatening because of its effect on membrane potentials, particularly of heart muscle. The serum potassium concentration

Heparin sodium is an extremely useful medication with demonstrated benefit in a number of clinical settings. Physicians need to be aware of the potential complication of hyperkalemia, especially in patients with renal insufficiency or diabetes mellitus. Discontinuation of heparin therapy is necessary to reverse the suppression of aldosterone.

Physiologic and pathologic events that occur in patients as they grow older may result in distal renal tubular dysfunction, as well as decreased levels of plasma renin activity and plasma aldosterone. Such alterations result in a tendency toward hyperkalemia.

We have described three patients with diabetes and renal insufficiency who had hyperkalemia during heparin therapy. These cases lend support to previous findings, and emphasize the clinical importance of this entity. We believe that heparin-induced hyperkalemia is a potentially life-threatening problem that is more common than previously appreciated ...

Therapeutic Approach to Hyperkalemia
Nephron, 2002The foremost step in the initial clinical management of hyperkalemia is to decide whether a hyperkalemic patient requires immediate treatment to avoid a life-threatening situation (serum potassium concentration >6.0 mEq/l and EKG changes). When the decision for urgent treatment of hyperkalemia is based on EKG changes, an important caveat for ...
