Potassium chloride: izici nokusetshenziswa kwezolimo futhi imithi

potassium ion (K +) yisona sakhiwo esibhekele intracellular seka imvelo. I cytoplasm bagxila cishe 90% potassium ku senani Imininingwane. Potassium ukumuncwa ikakhulukazi kwenzeka emathunjini amancane. isisindo salo eyinhloko emathunjini emgudwini wegazi bese ku nezicubu. Ukuba Wedwa kwalesi sakhi kusuka emzimbeni kwenzeka ngokusebenzisa nezinso. I umchamo equkethwe potassium njengoba usawoti wezinto ezingaphili (sulphate, phosphate) organic (uric acid). Iqhaza main ion K + emzimbeni - ekugcinweni kokuthula excitability kletkok, ngokuyinhloko kwemisipha. Potassium chloride e lokuhlala aphansi kunciphisa ubuningi kanye amplitude Kufinyeta inhliziyo. Myocardium esabelayo i anda ion lokuhlushwa K + lehla conduction futhi excitability. Ukweqisa izidakamizwa yalesi izidakamizwa kungabangela ukuboshwa ngisho inhliziyo. Ukuntula kwalesi sakhi oketshezini olungenambala lwegazi kwandisa ingozi arrhythmias. Lokhu kungenzeka uma usebenzisa ngemithamo enkulu glycosides inhliziyo (digitalis). Ngosizo potassium ion okuyinto eziqukethwe abomvu egazi, wenziwa umoya-mpilo ezokuthutha ne-carbon dioxide ngo-hemoglobin. elementi Macro ehilelekile inhlangano futhi ukudluliswa kwe-nerve amaza kwezitho innervated. Uma potassium chloride is busuka umzimba, ezingeni acetylcholine futhi ukuqhanyelwa besigaba nozwela isimiso sezinzwa is kakhulu anda. Ukuphatha i-intravenous zomuthi kuvusa excretion adrenaline by the nezindlala adrenal. Potassium chloride, kanye, nezinye nosawoti kwalesi sakhi liveza isinyathelo isisu.

Kumele ukuthi lesi sici Macro ehilelekile ekunakekeleni acid-ane-alikhali ibhalansi emzimbeni. Ubamba lichaza ukulawulwa ingcindezi osmotic, ukwakheka kanye hydrolysis zezakhi phosphate okuyinto abacebile amandla (ATP, AMP, Adp, creatine phosphate, njll), enqubeni phosphorylation. Regulation potassium umzimba emzimbeni kungenxa aldosterone. Ngokunciphisa aldosterone uketshezi incipha potassium excretion izvivistyh distal tubules kwezinso, ngakho Ukukhetha yayo umchamo incipha, kanye serum lokuhlushwa uketshezi extracellular namaseli, Ngakolunye kwandisa.

Potassium chloride: kusetshenziswa imithi

  I izinkomba ukusetshenziswa kwalesi izidakamizwa hypokalemia, arrhythmia yinto ehlukile, ukudakwa amalungiselelo digitalis, kanye ifomu hypokalemic ukukhubazeka gqwa. Ukuze kuncishiswe imiphumela emibi hydrochlorothiazide, potassium chloride busuka yokwakheka ezinye izidakamizwa antihypertensive. Hypokalemia kungabangela ukuphazamiseka ukusebenza kwemizwa uhlelo, inhliziyo, imisipha, isimiso sokujikeleza kwegazi nezinso. Ngezinye izikhathi hypokalemia uphela kwemisipha nokukhubazeka kanye ikhoma.

Potassium chloride ezinqunyiwe ngomlomo kanye ngemithambo yegazi. Ngokuvamile , abaphathi parenteral isetshenziswa ezimweni lapho ukuqedwa okusheshayo imihlola sokugembula. Ngenxa yale njongo, 4 isixazululo amaphesenti isidakamizwa for 40% i-glucose. Potassium chloride kumele kusetshenziswe ngokuqapha okukhulu. Early uphawu emitholampilo lokudakwa kukhona paresthesias. Ukudakwa nge aphoyintimenti enteral kungenzeka ngesimo isicanucanu, ukuhlanza, ukukhishwa yisisu.

Potassium chloride is contraindicated labo abagcina ukwephula kwezinso umsebenzi excretory. Kulokhu, K + ion buthelela egazini, okungaholela ukudakwa.

Potassium chloride: asetshenziswa kwezolimo

Lokhu usawoti kuyinto enhle kakhulu umanyolo umquba. Potassium chloride esetshenziselwa Umanyolo kakolweni nezinye izitshalo, okuyizinto ingazikhathaleli isinyathelo anobuthi chlorine. Izitshalo hypersensitive ukuze isenzo chlorine kukhona yefilakisi, amazambane, ugwayi, utamatisi, nezitshalo Ornamental kanye ezisawolintshi. Ngakho-ke, ukuze ondle lezi zitshalo kanye musa ukutusa ukusetshenziswa potassium chloride.
