Isisu osmotic - kuyini? Uhlu izidakamizwa, lo mshini wezenzo

Yingakho abaningi: "? isisu - kuyini" Kulesi sihloko uzofunda ukuthi kuyini nokuthi yini isetshenziswa.

Yezemithi izidakamizwa

isisu osmotic buyisidakamizwa okuyinto okukhishwe amanzi kusukela izicubu evuvukele. Ngakho-ke, kwandisa umthamo umchamo kanye Imiphumela uketshezi okweqile kusukela umzimba. Lokhu kuthuthukisa igazi ligeleze izinso, nakho kwandisa ukusebenza kwabo. ngaleyo ndlela Izinso ziqala ukusebenza kangcono kanye lemifanekiso. It kwandisa plasma osmolyaemost futhi ushukumisela kuyo uketshezi kwezitho nezicubu (ubuchopho, inhlamvu yeso) esegazini. Uma lokhu kwenzeka kanye ukuhoxiswa ketshezi chlorine, sodium, kanye potassium. Kungxenye yokugcina siboniswa nengcosana ukuthi akuvezi balahlekelwa kakhulu.

pharmacokinetics

isisu osmotic is akheka (ezincane) esibindini. Lokhu kuhambisana kumiswa glycogen. Lokukhipha kusuka emzimbeni kwenzeka ngemva filtration (glomerular) ngokusebenzisa nezinso. reabsorption Tubular akusho lutho.

Izinkomba ngoba ukusetshenziswa kwezidakamizwa

isisu osmotic esisemqoka ngesikhathi edema palsy, umfutho wegazi ophakeme intracranial futhi intraocular, noma ngesikhathi ekuhlaseleni glaucoma efomini oyingozi.

izidakamizwa ezisetshenzisiwe yaleli qembu at oliguria ukwehluleka oyingozi kwezinso shape. Kulesi simo isisu osmotic isetshenziswa lapho likhuluma ngokwanda kwabantu abathola diuresis liyadingeka. Lezi zimali ingasetshenziswa kuphela ngenkathi sigcina ikhono ukuhlunga.

Futhi okudingeka zithathwe uma ushevu nezidakamizwa lithium, bromides, salicylates futhi barbiturates.

isisu osmotic - izidakamizwa ukuthi Site ukusetshenziswa ngemva kokufaka igazi, lalingahambelani, phakathi ukuthuthukiswa yezinkinga post-ukumpompela.

Ezimweni eziningi, bajwayele phakathi nezinqubo ezithile zokuhlinza ezifana nokuhlinzwa dlula nokuhlinzwa nge kwegazi extracorporeal.

Lapho beshaqekile, ukusha, sepsis, peritonitis isisu ukukhuthaza ngcono isiphelo sesimiso ezinobuthi kusuka emzimbeni. Bona kunciphise umfutho wegazi.

Izimo ukusetshenziswa

isisu osmotic kungenzeka ingasetshenziswa uma:

• esingamahlalakhona kwezinso ngefomu ezingamahlalakhona.
• Ukuphulwa umthamo filtration we nezinso.
• Kwesobunxele ukwehluleka ventricular futhi edema yamaphaphu.
• Oluhambisana unhlangothi.
• ukopha Subarachnoid.
• Ngo amanzi emzimbeni ezinzima.

Izidakamizwa akufanele kuthathwe ngaphandle udokotela. Ukusebenzisa kwabo ngaphandle kwesidingo kungaholela emiphumeleni engathí sina.

side effects

Phakathi ukusetshenziswa kwezidakamizwa babelemisebenzi eminye imiphumela emibi ekwazi ukuletha ukungakhululeki womuntu.

Lezi zihlanganisa:

• ubuhlungu Shona.
• Ukucanuzela kwenhliziyo nokuhlanza.
• Ukopha futhi ukufa kwezicubu nabo izimali ngaphansi kwesikhumba.
• Kungase kube nomphumela Rebound.
• Okungenzeka nitrogen anda (asalile) amazinga.

Ngokuvamile, lapho ukubonakaliswa okunjalo side effects kufanele ayeke ukuthatha izidakamizwa ngokushesha futhi kudokotela. Ngeke ulungise isilinganiso semithi oyidlayo noma esikhundleni esebenzisa umkhiqizo ofana.

Yini imithi yokuhlambulula isisu osmotic?

Indlela ethandwa kakhulu kubhekwa "Mannitol". Yokusetshenziswa kuzokuvumela ukuba simazi izici zayo.

Futhi kuleli qembu izidakamizwa yilezi:

• "Torasemide."
• "Bumetanide."
• "Xipamide".
• "Chlorthalidone."
• "Polythiazyl".

Lolu uhlu olungaphelele izidakamizwa ezingasiza ne edema kanye nezinye izifo. Kufanele ngeke sisetshenziswe ngaphandle kwemvume udokotela, kanye "Mannitol". Yokusetshenziswa ngeke akunike isiqinisekiso sokuthi wena kahle ukhethe abale umthamo.

izici Comparative

"Mannitol" lisetshenziswa kaningi ngaphezu nezinye ukwakhiwa ngenxa yokuthi kunamandla futhi isikhathi eside, futhi akusho ukwandisa okuqukethwe nitrogen ngesimo igazi asalile. Kulokhu, urea kungcono futhi shí kwezitho nezicubu. Lokhu kungadala ubuchopho hydration futhi kwandise ingcindezi yokufuna ngaphakathi ugebhezi ngemuva kwamahora 6-7 emva nokuphathwa izidakamizwa ngemithambo yegazi.

isisu potassium-engashiyi

Osmotic isisu potassium-engashiyi ungasusi potassium emzimbeni, njengoba kuqhathaniswa isisu elula osmotic. Izidakamizwa fanele kuze lo xuku nethonya elihle ku-imisipha yenhliziyo, kodwa abe munye kusimo uma ziqhathaniswa ejenti ukuthi ususe potassium. It itholakala lokuthi leso senzo sabo kancane kancane, futhi iqala kuphela ngosuku wesibili noma wesithathu emva isicelo. Kulokhu, umphumela kubo ihlala isikhathi eside.

isisu potassium-engashiyi, odokotela batusa ukusebenzisa lihambisana namanye isisu. Ziyakwazi ukusetshenziswa olulodwa ukususwa ukuvuvukala kuyinto engathandeki, njengoba nethonya elitheni.

Ayenqatshelwa ukuyisebenzisa, uma umuntu ngokoma kwesibindi, ukwehluleka kwezinso, ifomu oyingozi futhi ezingalapheki, hyponatremia futhi hyperkalemia.

Ukuthola imithi ukuthi singabakaNkulunkulu leli qembu, uvunyelwe kuphela kadokotela.

Ukusetshenziswa isisu ekukhulelweni

isisu osmotic ungafaka isicelo kuphela uma inzuzo unina bulingana ingozi embungwini. Isinqumo lokuqoka udokotela kuthatha ngemuva kokwenza ukuhlola kanye cwaningo.

ukweqisa izidakamizwa

Uma umthamo iqondiswa idlula kuyinsakavukela hypervolemia angagcina okhushuliwe ingcindezi intracranial baphazamise electrolyte namanzi ibhalansi. Kungenzeka futhi ukwandisa okwamanje ketshezi ngaphandle amaseli. Uma imithamo weqiwe kakhulu ke kuzokhulisa umthwalo inhliziyo. Abantu abanezifo komzimba ingakha yezinkinga eqinile ezidinga usizo lwezempilo ngokushesha.

Ngakho isisu - kuyini? Manje, ngemva kokufunda lesi sihloko, abantu abaningi bazi ukuthi impendulo yalo mbuzo. Leli qembu izidakamizwa ahlanganisa isisu, ezisetshenziswa ubuchopho ukuvuvukala, ukusha, sepsis kanye nezinye izifo eziningi. Ngenxa isinyathelo sabo bayokuhayela ngcono outflow uketshezi umchamo nokugeleza kwegazi e-izinso. Ukhuthaza filtration kangcono. Administration kwezidakamizwa kuleli qembu kuvunyelwe kuphela kadokotela, ngoba nguye kuphela ngeke ukubala wena umthamo efanele bese uhlole Izimo. Ngokuzimela ukwenza kube kunalokho nzima futhi ngezinye izikhathi ngisho engenakwenzeka.
