==Overview==
==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 [[arrhythmia]]s.
[[Hyperkalemia]] is an elevated [[blood]] level (above 5.1 mmol/L) of the [[electrolyte]] [[potassium]]. ". Extreme degrees of [[hyperkalemia]] are considered a [[medical emergency]] due to the risk of potentially fatal [[arrhythmia]]s. Hyperkalemia can be caused by reasons that include increased uptake, [[extracellular]] shift, tissue breakdown and impaired excretion from the [[body]].

===Life Threatening Causes===
(By organ system)
*Hyperkalemia can become a life-threatening condition if potassium levels are too high and body is not able to remove it effectively.

=== Ineffective elimination from the body===
===Causes in Alphabetical Order===
* [[Renal insufficiency]]
* [[Medication]] that interferes with urinary excretion:
** [[ACE inhibitor]]s and [[angiotensin II receptor antagonist|angiotensin receptor blockers]]
** Potassium-sparing [[diuretic]]s (e.g. [[amiloride]] and [[spironolactone]])
** [[Non-steroidal anti-inflammatory drugs|NSAIDs]] such as [[ibuprofen]], [[naproxen]], or [[Celebrex|celecoxib]]
** The [[Immunosuppressive drug#Drugs acting on immunophilins|calcineurin inhibitor]] immunosuppressants [[ciclosporin]] and [[Prograf|tacrolimus]]
** The antibiotic [[trimethoprim]]
** The antiparasitic drug [[pentamidine]]
* [[Mineralocorticoid]] deficiency or resistance, such as:
** [[Addison's disease]]
** [[Hypoaldosteronism|Aldosterone deficiency]], including reduced levels due to the blood thinner, [[heparin]]
** Some forms of [[congenital adrenal hyperplasia]]
** Type IV [[renal tubular acidosis]] (resistance of renal tubules to aldosterone)
* Gordon's syndrome (“familial hypertension with hyperkalemia”), a rare genetic disorder caused by defective modulators of salt transporters, including the [[thiazide-sensitive Na-Cl cotransporter]].
 
=== Excessive release from cells===
* [[Rhabdomyolysis]], [[burn (injury)|burns]] or any cause of rapid tissue [[necrosis]], including [[tumor lysis syndrome]]
* Massive [[blood transfusion]] or massive [[hemolysis]]
* Shifts/transport out of cells caused by [[acidosis]], low [[insulin]] levels, [[beta-blocker]] therapy, [[digoxin]] overdose, or the paralyzing anesthetic [[succinylcholine]]
 
=== Excessive intake===
* [[Intoxication]] with salt-substitute, potassium-containing dietary supplements, or potassium-chloride ([[KCl]]) infusion.  Note that for a person with normal kidney function and nothing interfering with normal elimination (see above), hyperkalemia by potassium intoxication would be seen only with large infusions of KCl or massive doses of oral KCl supplements.


===Lethal injection===
{{MultiCol|width:80%}}
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.
* [[Acidosis]]
 
* [[ACTH Deficiency]]
===Pseudohyperkalemia===
* [[Acute glomerulonephritis]]
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.<ref>Sevastos N et al. (2006) Pseudohyperkalemia in serum: the phenomenon and its clinical magnitude. J Lab Clin Med, 147(3):139-44; PMID 16503244.</ref> 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).<ref>Don BR et al. (1990) Pseudohyperkalemia caused by fist clenching during phlebotomy. N Engl J Med, 322(18):1290-2; PMID 2325722.</ref>; or by a delay in the processing of the blood specimen.  It can also occur in specimens from patients with abnormally high numbers of [[platelet]]s (>1,000,000/mm³), [[leukocyte]]s (> 100 000/mm³), or [[erythrocyte]]s (hematocrit > 55%). People with "leakier" [[cell membrane]]s have been found, whose blood must be separated immediately to avoid pseudohyperkalemia.<ref>Iolascon A et al. (1999) Familial pseudohyperkalemia maps to the same locus as dehydrated hereditary stomatocytosis. Blood, 93(9):3120-3; PMID 10216110.</ref>

Overview

Hyperkalemia is an elevated blood level (above 5.1 mmol/L) of the electrolyte potassium. ". Extreme degrees of hyperkalemia are considered a medical emergency due to the risk of potentially fatal arrhythmias. Hyperkalemia can be caused by reasons that include increased uptake, extracellular shift, tissue breakdown and impaired excretion from the body.
