Ziziphi ii-Anticoagulants zegazi?

Ama-reagents amachiza okanye izinto ezinokuthintela ukudibanisa kwegazi zibizwa ngokuba yi-anticoagulants, njenge-anticoagulants yendalo (i-heparin, i-hirudin, njl.), I-Ca2 + i-chelating agents (i-sodium citrate, i-potassium fluoride).I-anticoagulants esetyenziswa ngokuqhelekileyo ibandakanya i-heparin, i-ethylenediaminetetraacetate (i-EDTA ityuwa), i-citrate, i-oxalate, njl. Kwisicelo esisebenzayo, i-anticoagulants kufuneka ikhethwe ngokweemfuno ezahlukeneyo zokufumana iziphumo ezifanelekileyo.

Isitofu seHeparin

Inaliti ye-Heparin yi-anticoagulant.Isetyenziselwa ukunciphisa amandla egazi ukujika kwaye incede ukukhusela amahlwili ayingozi ukuba enze imithambo yegazi.Eli chiza ngamanye amaxesha libizwa ngokuba ligazi elincinci, nangona linganciphisi igazi.I-Heparin ayinyibiliki amahlwili egazi asele enziwe, kodwa inokuwathintela ekubeni abe makhulu, nto leyo enokukhokelela kwiingxaki ezinzulu.

I-Heparin isetyenziselwa ukukhusela okanye ukunyanga izifo ezithile ze-vascular, intliziyo kunye nemiphunga.I-Heparin ikwasetyenziselwa ukuthintela ukujiya kwegazi ngexesha lotyando lwentliziyo evulekileyo, utyando lwentliziyo, utyando lwezintso kunye notofelo-gazi.Isetyenziswa kwiidosi eziphantsi ukukhusela i-thrombosis kwezinye izigulana, ngakumbi ezo kufuneka zenziwe utyando oluthile okanye zihlale ebhedini ixesha elide.I-Heparin ingasetyenziselwa ukuxilonga kunye nokunyanga isifo esibi segazi esibizwa ngokuba yi-disseminated intravascular coagulation.

Inokuthengwa kuphela ngomyalelo kagqirha.

Ityuwa ye-EDTC

Yikhemikhali ebopha ii-ion zesinyithi ezithile, njengecalcium, imagnesium, ilothe, kunye nentsimbi.Isetyenziselwa amayeza ukuthintela iisampulu zegazi ekujikeni kunye nokususa i-calcium kunye nelothe emzimbeni.Ikwasetyenziselwa ukuthintela iibhaktheriya ekwenzeni i-biofilms (iimaleko ezibhityileyo ezincanyathiselwe kumphezulu).Yi-arhente etshisayo.Ikwabizwa ngokuba yi-ethylene diacetic acid kunye ne-ethylene diethylenediamine tetraacetic acid.

I-EDTA-K2 ecetyisiweyo yi-International Hematology Standardization Committee ine-solubility ephezulu kunye nesantya esikhawulezayo se-anticoagulation.
