Yintoni uvavanyo lwe-PTT (inxenye yetromboplastin time)?

Ixesha lovavanyo lwe-thromboplastin (PTT) elilinganisa ixesha elithathayo ukuze igazi lenze i-clot. Ngokwesiqhelo, xa usikwa okanye wenzakala okubangela ukopha, iiproteni ezisegazini lakho ezibizwa ngokuba zii-coagulation zisebenza kunye ukwenza iqokobhe legazi. Ihlwili liyakuthintela ekuphulukaneni negazi elininzi.

Unezinto ezininzi ezixineneyo egazini lakho. Ukuba kukho naziphi na izinto ezilahlekileyo okanye ezineziphene, kunokuthatha ixesha elide kuneliqhelekileyo ukuba igazi lijiye. Ngamanye amaxesha, oku kubangela ukopha okunzima, okungalawulwayo. Uvavanyo lwe-PTT lujonga umsebenzi wezinto ezithile zokuqina. Oku kubandakanya izinto ezaziwa njenge factor VIII, factor IX, factor X1, and factor XII.

Amanye amagama: ixesha elisebenzayo le-thromboplastin, i-aPTT, iprofayili yendlela yokuqina kwendlela

Isetyenziselwa ntoni?

Uvavanyo lwe-PTT lusetyenziselwa:

• Jonga umsebenzi wezinto ezithile zokujiya. Ukuba naziphi na kwezi zinto zilahlekile okanye zinesiphene, oko kunokuthetha ukuba unesifo esophayo. Ukuphazamiseka kwegazi liqela leemeko ezinqabileyo apho igazi lingagugi ngesiqhelo. Esona sifo saziwayo sopha kakhulu yi-hemophilia.
• Fumanisa ukuba ngaba sikhona esinye isizathu sokopha ngokweqile okanye ezinye iingxaki zokunqanda igazi. Oku kubandakanya izifo ezithile ezizimeleyo ezibangela amajoni omzimba ukuba ahlasele izinto ezixineneyo.
• Ukubeka esweni abantu abathatha i-heparin, uhlobo lwamayeza athintela ukubola. Kwezinye iingxaki zokopha, igazi livaleka kakhulu, kunokuba lincinci kakhulu. Oku kunokubangela ukuhlaselwa yintliziyo, ukubetha, kunye nezinye iimeko ezisongela ubomi. Kodwa ukuthatha i-heparin kakhulu kunokubangela ukopha kakhulu kwaye kuyingozi.

Kutheni ndifuna uvavanyo lwe-PTT?

Unokufuna uvavanyo lwe-PTT ukuba:

• Ukopha okungathethekiyo
• Ukuqhekeka ngokulula
• Yiba nehlwili legazi emithanjeni okanye kwimithambo yegazi
• Unesifo sesibindi, esinokuthi ngamanye amaxesha sibangele iingxaki ekunqandeni igazi
• Uya kufumana utyando. Utyando lunokubangela ukulahleka kwegazi, ke kubalulekile ukuba wazi ukuba unengxaki yokujiya.
• Ukhe waphuphuma kaninzi
• Bathatha iHerparin

Kwenzeka ntoni ngexesha lovavanyo lwe-PTT?

Ingcali yokhathalelo lwempilo iyakuthatha isampulu yegazi kumthambo engalweni yakho, isebenzisa inaliti encinci. Emva kokuba inaliti ifakiwe, inani elincinci legazi liya kuqokelelwa kwityhubhu yovavanyo okanye igutyana. Unokuziva uluma kancinci xa inaliti ingena okanye iphuma. Oku kuhlala kuthatha imizuzu engaphantsi kwesihlanu.

Ngaba kuya kufuneka ndenze nantoni na ukulungiselela uvavanyo?

Awudingi naluphi na ulungiselelo olukhethekileyo lovavanyo lwe-PTT.

Ngaba bukhona ubungozi kuvavanyo?

Mncinci kakhulu umngcipheko wokuvavanywa kwegazi. Unokuba nentlungu encinci okanye ukrakra kwindawo apho inaliti yafakwa khona, kodwa uninzi lweempawu zihamba ngokukhawuleza.

Zithetha ntoni iziphumo?

Iziphumo zovavanyo lwe-PTT ziya kubonisa ukuba kuthathe ixesha elingakanani ukuba igazi lakho lijiye. Iziphumo zihlala zinikwa inani lemizuzwana. Ukuba iziphumo zakho zibonisa ukuba igazi lakho lithathe ixesha elide kunexesha eliqhelekileyo lokuvala, oko kunokuthetha ukuba une:

• Ukuphazamiseka kwegazi, njenge-hemophilia okanye isifo se-von Willebrand. Isifo seVon Willebrand sesona sifo siqhelekileyo sopha, kodwa sihlala sidala iimpawu ezinzima kunezinye iingxaki zokopha.
• Isifo sesibindi
• I-Antiphospholipid antibody syndrome okanye i-lupus anticoagulant syndrome. Ezi zizifo ezizimele zodwa ezibangela ukuba amajoni akho omzimba ahlasele imeko yakho yokuqina.
• Ukunqongophala kukaVitamin K. UVitamin K udlala indima ebalulekileyo ekwenzeni izinto ezijiyayo.

Ukuba uthatha i-heparin, iziphumo zakho zinokunceda ukubonisa ukuba uthatha idosi elungileyo. Uya kuvavanywa rhoqo ukuze uqiniseke ukuba idosi yakho ihlala kwinqanaba elifanelekileyo.

Ukuba ufumanisa ukuba unengxaki yokopha, thetha nomboneleli wakho wezempilo. Ngelixa lungekho unyango lwezifo ezininzi zokopha, lukhona unyango olufumanekayo olunokunceda ukulawula imeko yakho.

Funda ngakumbi malunga novavanyo lwelabhoratri, uluhlu lweereferensi, kunye neziphumo zokuqonda.

Ngaba ikhona enye into endifuna ukuyazi malunga novavanyo lwe-PTT?

Uvavanyo lwe-PTT luhlala lu-odolwa kunye nolunye uvavanyo lwegazi olubizwa ngokuba lixesha leprothrombin. Uvavanyo lwexesha leprothrombin yenye indlela yokulinganisa ubuchule bokujiya.
