Ayini Ama-Anticoagulant Egazi?

Ama-reagent amakhemikhali noma izinto ezingavimbela ukujiya kwegazi zibizwa ngokuthi ama-anticoagulant, njenge-anticoagulant yemvelo (i-heparin, i-hirudin, njll.), ama-Ca2+chelating agents (i-sodium citrate, i-potassium fluoride). Ama-anticoagulant asetshenziswa kakhulu afaka i-heparin, i-ethylenediaminetetraacetate (usawoti we-EDTA), i-citrate, i-oxalate, njll. Ekusetshenzisweni okungokoqobo, ama-anticoagulant kufanele akhethwe ngokwezidingo ezahlukene ukuze kutholakale imiphumela emihle.

Umjovo we-Heparin

Umjovo we-Heparin umuthi oqeda ukujiya kwegazi. Usetshenziselwa ukunciphisa ikhono legazi lokujiya kwegazi futhi usize ekuvimbeleni ukwakheka kwamahlule ayingozi emithanjeni yegazi. Lo muthi ngezinye izikhathi ubizwa ngokuthi umuthi wokunciphisa igazi, nakuba empeleni ungalinciphisi igazi. I-Heparin ayincibilikisi amahlule egazi asevele akhekile, kodwa ingawavimbela ukuba abe makhulu, okungaholela ezinkingeni ezinkulu kakhulu.

I-Heparin isetshenziselwa ukuvimbela noma ukwelapha izifo ezithile zemithambo yegazi, inhliziyo kanye namaphaphu. I-Heparin isetshenziselwa futhi ukuvimbela ukujiya kwegazi ngesikhathi sokuhlinzwa kwenhliziyo evulekile, ukuhlinzwa kwenhliziyo edlulayo, ukuhlanza izinso kanye nokumpontshelwa igazi. Isetshenziswa ngemithamo ephansi ukuvimbela i-thrombosis kwezinye iziguli, ikakhulukazi lezo okumele zenze izinhlobo ezithile zokuhlinzwa noma okumele zihlale embhedeni isikhathi eside. I-Heparin ingasetshenziswa futhi ukuxilonga nokwelapha isifo segazi esingathi sína esibizwa ngokuthi i-disseminated intravascular coagulation.

Ingathengwa kuphela ngomuthi kadokotela.

Usawoti we-EDTC

Ikhemikhali ebopha ama-ion athile ensimbi, njenge-calcium, i-magnesium, i-lead, kanye ne-iron. Isetshenziswa kwezokwelapha ukuvimbela amasampula egazi ukuthi angaqini futhi isuse i-calcium kanye ne-lead emzimbeni. Iphinde isetshenziswe ukuvimbela amabhaktheriya ekwakheni ama-biofilms (izingqimba ezincane ezinamathele ebusweni). Iyisithako esihlukanisayo. Ibizwa nangokuthi i-ethylene diacetic acid kanye ne-ethylene diethylenediamine tetraacetic acid.

I-EDTA-K2 enconywe yi-International Hematology Standardization Committee inokuncibilika okuphezulu kakhulu kanye nesivinini esisheshayo sokuvimbela ukujiya kwegazi.
