Isixazululo "I-sodium chloride". Inkcazelo

I-chloride ye-sodium inikeza ixabiso eliqhubekayo lokunyanzeliswa kwe-osmotic. Iqulethwe kwisixa se-0.5-0.9% egazini, kunye nakwimitha yamanzi. Kwiimeko eziqhelekileyo, i-sodium chloride ingena emzimbeni womntu ngokutya okudliwayo, kodwa kukho iimeko ezininzi xa isixa salo sihla, esibangela kwimiphumo ethile. Ngokuqhelekileyo ukukhubazeka kwe-chloride ye-sodium kuvela kwi-excretion eyandisiweyo yesodium ukusuka emzimbeni kunye nokungabi nzuzo kwembuyekezo kule meko. I-sodium ikhutshwe ngokukhawuleza kwiimeko ezininzi, umzekelo, ngesifo sohudo, ukuhlanza okunzima kunye nokunciphisa umsebenzi we-correnx ye-adrenal.

Xa ukungabikho kwe-sodium chloride kubonakala emzimbeni, oku kubangela ukwandisa kwi- viscosity yegazi, njengoko igazi liqala ukungena ngodonga lwesitya kumathishini azungezile (i-edema iyaqhubeka). Ukuba ulahleko luphawuleka kwaye aluzange luzaliswe ngaphambili, ukuxhamla ngokukhawuleza kwemisipha ephosakeleyo kunye nokuphazamiseka kwemisipha yamathambo angabonakala. Kamva, kukho iimpawu zokuphazamiseka emsebenzini wesimo senzwa kunye nobunzima ekujikelezeni kwegazi.

Okwangoku, i-chloride ye-sodium isoloko isetyenziswa kakhulu kwiyeza njengezisombululo zokulawulwa kwe-intravenous. Ngokuxhomekeke kwinto yokugxininiswa kwento kwisisombululo, ukwahlula i-isotonic kunye ne-hypertonic. Isisombululo se-isotonic sineengcinezelo ze -osmotic elingana noxinzelelo lwe- osmotic ye-plasma yegazi, esi sixazululo sibizwa ngokuba nesisombululo saline. Isisombululo se hypertonic , sona sinexinzelelo lwe-osmotic ephezulu kunaplasma.

Ukubonakala kwesisombululo "I-sodium chloride" (ukulungiselela ukungena emzimbeni) ngumbane ongenakubala ongenawo unambitha onosawoti. Isimo esisinyanzelo sizalisekile isicombululo, kunye ne-pyrogenicity (akufanele ikhulise ukushisa komzimba womntu xa ilawulwa).

Isisombululo se-isotonic sodium chloride ngokuqhelekileyo isetyenziswe njengendlela yokwexeka. Ngokwandisa umthamo wegazi ojikelezayo, izinto ezinobuthi zikhawuleza zikhutshwe emzimbeni ngamazinyo okanye zingasebenzi ngokudlula kwigazi ngenxa yesibindi.

Ngokwenene, i-chloride ye-sodium isetyenziswe xa imeko ivela, xa kukho ukwanda kwe-fluid emzimbeni (izifo ezahlukeneyo ezihambisane nokuhlanza ngokugqithiseleyo kunye nohudo, ukutshisa, ukulahleka kwegazi ngokubanzi, ngakumbi ngaphambi kokuba uphelelwe igazi). Oku kuqinisekisa ukugcinwa kwegazi kwi-osmotic ingcinezelo esomeleleyo engavumeli i-plasma yegazi ukuba ihambe ngaphaya kwemida yegazi kwaye inike i-viscosity yegazi.

Ukulungiselela "i-sodium chloride". Imiyalelo yokusetyenziswa

Isisombululo kufuneka senziwe nge-intravenously okanye ngaphantsi. Kwakhona, i-chloride ye-sodium ingenelwa nge-enemas. Kodwa eyona nto iphambili kwaye ikhethwayo yiyojojo yokuxhoma isisombululo kwangaphakathi. Isixa sesisombululo esilawulwayo kufuneka kuxhomekeke kwisixa samanzi alahlekileyo. Kwiimeko ezinzima kakhulu (utywala obukhulu, ukutshisa okukhulu, njl.) Kufakwa kwiititha ezintathu.

Iimpawu ze-sodium chloride. Imiphumo emibi

I-chloride ye-sodium yinkomfa yeryuwa equlethwe kwi-plasma yegazi. Ngenxa yokunyanzeliswa kwe-osmotic eyenziwe yiyo, igazi alikwazi ukushiya igazi, kodwa ngokukhawuleza ukuba i-sodium iyawa, ukulungiswa kwangoko kwiplasma kuyimfuneko. Kwezinye iimeko, ukulawulwa kwe-sodium chloride ineempembelelo. Ukuba isisombululo esiphezulu siye saziswa, oku kungakhokelela ekusebenziseni i-acidification (ukwanda kwexabiso le-chloride ions kukhokelela kwi-acidosis). Ukongezelela, kukho ukuvela kwe-hyperhydration (ukwanda kwentsholongwane equlethwe emzimbeni), kunye nokwanda kwe-potassium emzimbeni.
