Ityhubhu yeGazi eVacuum yoNyango
Inkcazelo emfutshane:
Umnqwazi obomvu ubizwa ngokuba ityhubhu ye-serum eqhelekileyo, kwaye isitya sokuqokelela igazi asinazo izongezo.Isetyenziselwa i-serum biochemistry yesiqhelo, ibhanki yegazi kunye neemvavanyo ezinxulumene ne-serological.
IVenipuncture
Kwezamayeza, ukuhlatywa kweveni okanye i-venepuncture yinkqubo yokufumana ufikelelo kwi-intravenous ngenjongo yokuthathwa kwegazi le-venous (ekwabizwa ngokuba yi-phlebotomy) okanye unyango lwe-intravenous.Inhealthcare---le nkqubo yenziwa ngoososayensi bezonyango, oogqirha, ii-EMTs ezithile, i-paramedics, i-phlebotomists. , amagcisa edialysis, kunye nabanye abasebenzi abongikazi.Kunyango lwezilwanyana, inkqubo yenziwa ngoogqirha bezilwanyana kunye neengcali zonyango lwezilwanyana.
Kubalulekile ukulandela inkqubo eqhelekileyo yokuqokelela iisampulu zegazi ukufumana iziphumo ezichanekileyo zelabhoratri.Nayiphi na impazamo ekuqokeleleni igazi okanye ekugcwaliseni iityhubhu zovavanyo inokukhokelela kwiziphumo zelebhu ezigwenxa.|
I-Venipuncture yenye yezona nkqubo zixhaphakileyo kwaye yenziwa ngaso nasiphi na izizathu ezihlanu:
1. Fumana igazi ngeenjongo zokuxilonga;
2. Beka iliso kwinqanaba leenxalenye zegazi;
3. Ukuqhuba unyango lonyango, kuquka iziyobisi, isondlo okanye ichemotherapy;
4. Ukususa igazi ngenxa yamanqanaba aphezulu esinyithi okanye iiseli ezibomvu zegazi (iiseli ezibomvu zegazi);
5. Qokelela igazi ukuze lisetyenziswe kamva, ngokuyintloko kumntu onikela ngegazi okanye olunye utofelo-gazi lomntu.
Uhlalutyo lwegazi sisixhobo esibalulekileyo sokuxilonga esifumaneka kwiiklinikhi ngaphakathi kokhathalelo lwempilo.Igazi lixhaphake ngokufunyanwa kwimithambo engaphezulu yelungu eliphezulu.
I-Median cubitalvein, elele ngaphakathi kwe cubital fossa ngaphambili ukuya engqinibeni, isondele kumphezulu wolusu ngaphandle kwemithambo-luvo emikhulu ebekwe kufutshane.Eminye imithambo enokuthi isetyenziswe kwicubital fossa forvenipuncture ibandakanya i-cephalic, i-basilic, kunye ne-median antebrachial. imithambo.
Ubungakanani begazi obungumzuzu bunokuthatyathwa ngokuthathwa kwesampulu yeminwe kwaye iqokelelwe kwiintsana ngokubethelwa isithende okanye kwimithambo yentloko ngenaliti enamaphiko.
I-Phlebotomy (ukusika kumthambo) ikwalunyango lwezifo ezithile ezifana ne-hemochromatosis kunye ne-primary and secondary polycythemia.
