Overview

Hyperkalemia (AE) or Hyperkalaemia (BE) is an elevated blood level (above 5.0 mmol/L) of the electrolyte potassium. The prefix hyper- means high (contrast with hypo-, meaning low). The middle kal refers to kalium, which is Latin for potassium. The end portion of the word, -emia, means "in the blood". Extreme degrees of hyperkalemia are considered a medical emergency due to the risk of potentially fatal arrhythmias.

Most common

• ACE inhibitors
• Acidosis
• Addisonian crisis
• Beta blockers
• Blood transfusion and complications
• Cirrhosis
• Diabetic nephropathy
• Increased ingestion of high potassium foods
• Malnutrition
• Renal tubular acidosis
• Renal failure

Lethal injection

Hyperkalemia is intentionally brought about in an execution by lethal injection, potassium chloride being the third and last of the three drugs generally administered to cause death, after sodium thiopental has rendered the subject unconscious, then pancuronium bromide has been added to cause respiratory collapse.

Pseudohyperkalemia

Pseudohyperkalemia is a rise in the amount of potassium that occurs due to excessive leakage of potassium from cells, during or after blood is drawn. It is a laboratory artifact rather than a biological abnormality and can be misleading to doctors. Pseudohyperkalemia is typically caused by hemolysis during venipuncture (by either excessive vacuum of the blood draw or by a syringe needle that is of too fine a gauge); excessive tournequet time or fist clenching during phlebotomy (which presumably leads to efflux of potassium from the muscle cells into the bloodstream).; or by a delay in the processing of the blood specimen. It can also occur in specimens from patients with abnormally high numbers of platelets (>1,000,000/mm³), leukocytes (> 100 000/mm³), or erythrocytes (hematocrit > 55%). People with "leakier" cell membranes have been found, whose blood must be separated immediately to avoid pseudohyperkalemia.
