O lenei faʻataʻitaʻiga e fua ai le aofaʻi o le potassium i le suavai vaega (serum) o le toto. Potassium (K +) fesoasoani i neura ma maso e fesoʻotaʻi. E faʻapea foi ona fesoasoani e aveʻese fualaʻau i sela ma faʻamaʻimau oloa mai sela.

Ole maualuga ole potassium ile tino e masani ona puleaina e le homone aldolone.

E manaʻomia se faʻataʻitaʻiga ole toto. Ole tele ole taimi ole toto e toso mai le uaua o loʻo tu i totonu ole tulilima poʻo tua ole lima.

Tele vailaʻau e mafai ona faʻalavelave ile iʻuga ole suʻega ole toto.

  • O le a taʻu atu e lau fomaʻi pe a manaʻomia lou taofia le toe inu o se vailaʻau ae e te leʻi faia lenei suʻega.
  • Aua neʻi tuʻu pe suia au vailaʻau e aunoa ma le talanoa muamua i lau tautua.

E te ono lagonaina sina tiga pe o se tiga pe a tuu le nila. E te ono lagonaina foi le tataina o le loto i le nofoaga pe a uma ona tosoina le toto.

O lenei suʻega o se vaega masani o le faʻavae poʻo le lautele metabolic vaega.

Oe ono maua lenei suʻega e suʻesuʻe pe mataʻi faʻamaʻi fatu. O le mafuaʻaga sili ona taatele o le maualuga toto potassium tulaga o faamaʻi fatugao.


E taua le potassium i le fatu galue.

  • E ono okaina e lau tautua lenei suʻega pe a iai ni faʻailoga o le toto maualuga poʻo ni faʻafitauli i le fatu.
  • Laititi suiga i le potassium tulaga mafai ona i ai se tele aafiaga i le gaioiga o neula ma maso, aemaise lava le fatu.
  • O le maualalo o le potassium e mafai ona taitai atu ai i le le tata o le tata o le fatu po o isi eletise leaga o le fatu.
  • Maualuga tulaga mafua ai le faʻaititia fatu gaioiga gaioiga.
  • Poo se tulaga e mafai ona taitai atu ai i le ola-lamatia loto faʻafitauli.

E mafai foi ona fai pe a masalomia e lau tautua le metabolic acidosis (mo se faʻataʻitaʻiga, e mafua mai ile maʻi suka le taofiofia) poo le alkalosis (mo se faʻataʻitaʻiga, e mafua mai ile tele o le puaʻi).

O isi taimi, o le faʻataʻitaʻiga o le potasiuma e mafai ona faia i tagata o loʻo osofaʻia le supa.

O le masani masani o 3.7 i le 5.2 milliequivalents i le lita (mEq / L) 3.70 i le 5.20 millimoles i le lita (millimol / L).

E masani ona fesuisuiaʻi vaega eseese o tau masani ile falefaigaluega eseese. Talanoa i lau tautua e uiga i le uiga o au faʻapitoa suʻega iʻuga.


O faʻataʻitaʻiga i luga atu o loʻo faʻaalia ai fuataga masani mo iʻuga mo nei suʻega. O nisi potu suesue e faʻaaoga eseese fuataga pe ono suʻesuʻeina faʻataʻitaʻi eseese.

Maualuga maualuga o potassium (hyperkalemia) atonu e mafua mai i:

  • Addison faʻamaʻi (seasea)
  • Totoina toto
  • O vailaʻau faʻapitoa e aofia ai le angiotensin liuaina o le enzyme (ACE) mea e taofia ai, poloka poloka (angiensensin receptor blockers) (ARBs), ma le potassium-sparing diuretics spironolactone, amiloride ma triamterene
  • Manuʻa manuʻa
  • Supa gasegase Hyperkalemic
  • Hypoaldosteronism (seasea tupu)
  • Le lava lelei o fatugaʻo pe le manuia
  • Metabolic poʻo respiratory acidosis
  • Faʻaleagaina sela mumu
  • Tele tele potasiuma i lau taumafataga

Maualalo tulaga o potasiuma (hypokalemia) ono mafua mai i:

  • Matuā poʻo le manava tatā
  • Cushing syndrome (seasea)
  • Diuretics pei o hydrochlorothiazide, furosemide, ma indapamide
  • Hyperaldosteronism
  • Supa faavaitaimi hypokalemic
  • Le lava potasiuma i le taumafataga
  • Stenosis alatoto
  • Acidosis tubular renal (seasea)
  • Talosaga

Afai e faigata ona ave le nila i totonu o le uaua e ave le toto faʻataʻitaʻiga, manuʻa i le mumu sela sela ono mafua ai le faʻasaʻolotoina o le potassium. Lenei ono mafua ai se sese maualuga taunuʻuga.


Hypokalemia tofotofoga; K +

  • Tofotofoga toto
