Luyintoni uvavanyo lwe-thromboplastin yexesha (PTT)?

Uvavanyo lwexeshana lwe-thromboplastin (PTT) luvavanyo lwegazi olunceda oogqirha bavavanye amandla omzimba wakho okwenza amahlwili egazi.

Ukopha kuphembelela uthotho lweempendulo ezaziwa ngokuba kukungunda okuxineneyo. Ukuxinana yinkqubo oyisebenzisayo ukuyeka ukopha. Iiseli ezibizwa ngokuba ziiplatelets zenza iplagi yokugubungela izicwili ezonakeleyo. Emva koko izinto ezijiyisayo zomzimba wakho ziyasebenzisana ukwenza ihlwili legazi. Amanqanaba asezantsi ezinto ezijiyileyo anokuthintela ihlwili ekubeni lenze. Ukusilela kwezinto ezijiyayo kunokukhokelela kwiimpawu ezinjengokopha kakhulu, ukuphuma kweempumlo eziqhubekayo, kunye nokugruzuka ngokulula.

Ukuvavanya ukubanakho kwegazi lomzimba wakho, ilabhoratri iqokelela isampulu yegazi lakho kwibhotile kwaye yongeza imichiza eya kwenza igazi lakho lijiye. Uvavanyo luthatha amanyathelo ukuba ithatha kangaphi imizuzwana ukuze ihlwili libumbe.

Olu vavanyo ngamanye amaxesha lubizwa ngokuba luvavanyo lwe-thromboplastin (APTT) olusebenzayo.

Kutheni ndifuna uvavanyo lwe-PTT?

Ugqirha wakho unoku-odola uvavanyo lwe-PTT ukuze aphande unobangela wokopha ixesha elide okanye okugqithileyo. Iimpawu ezinokubangela ugqirha ukuba ayalele olu vavanyo zibandakanya:

• Ukuqhuma kweempumlo rhoqo okanye okunzima
• ubunzima okanye ixesha elide lokuya esikhathini
• igazi kumchamo
• ukudumba kunye namalungu abuhlungu (abangelwa kukopha kwiindawo ezidibeneyo)
• ukutyunyuzwa ngokulula

Uvavanyo lwe-PTT alunakufumanisa imeko ethile. Kodwa iyanceda ugqirha wakho ukuba afunde ukuba ngaba imeko yakho yokujiya kwegazi isilele. Ukuba iziphumo zakho zovavanyo aziqhelekanga, ugqirha wakho uya kudinga uku-odola iimvavanyo ezingaphezulu ukuze abone ukuba yeyiphi na into eveliswa ngumzimba wakho.

Ugqirha wakho unokusebenzisa olu vavanyo ukubeka esweni imeko yakho xa uthatha i-heparin yegazi.

Ndizilungiselela njani uvavanyo lwe-PTT?

Amayeza aliqela anokuchaphazela iziphumo zovavanyo lwe-PTT. Oku kubandakanya:

• heparin
• iwarfarin
• Iasprini
• antihistamines
• ivithamin C
• chlorpromazine

Qinisekisa ukuba uxelele ugqirha wakho ngawo onke amayeza owathathayo. Kuya kufuneka uyeke ukuzithatha ngaphambi kovavanyo.

Zithini iingozi ezinxulumene novavanyo lwe-PTT?

Njengalo naluphi na uvavanyo lwegazi, kukho umngcipheko omncinci wokugruzuka, ukopha, okanye usulelo kwindawo yokuhlatywa. Kwiimeko ezinqabileyo, umthambo wakho unokudumba emva kokutsalwa kwegazi. Le meko yaziwa ngokuba yi-phlebitis. Ukufaka i-compress efudumeleyo amaxesha amaninzi ngemini kunokunyanga i-phlebitis.

Ukopha okuqhubekayo kunokuba yingxaki ukuba unesifo sokopha okanye uthatha amayeza okucoca igazi, njenge-warfarin okanye i-aspirin.

Lwenziwa njani uvavanyo lwe-PTT?

Ukwenza uvavanyo, i-phlebotomist okanye umongikazi uthatha isampuli yegazi engalweni yakho. Bacoca indawo ngotshwala kwaye bafaka inaliti emthanjeni wakho. Umbhobho ofakwe kule naliti uqokelela igazi. Emva kokuqokelela igazi elaneleyo, bayayisusa inaliti kwaye bagqume indawo yokugqobhoza ngephedi yetshi.

Ingcali yeelebhu yongeza iikhemikhali kule sampulu yegazi kwaye ilinganisa inani lemizuzwana eliyithathayo kwisampulu yokugquma.

Zithetha ntoni iziphumo?

Iziphumo eziqhelekileyo zovavanyo lwe-PTT

Iziphumo zovavanyo lwe-PTT zilinganiswa ngemizuzwana. Iziphumo eziqhelekileyo zihlala imizuzwana engama-25 ukuya kuma-35. Oku kuthetha ukuba kuthathe isampulu yegazi lakho kwimizuzwana engama-25 ukuya kwengama-35 ukuyogquma emva kokongeza iikhemikhali.

Imigangatho ngqo yeziphumo eziqhelekileyo inokwahluka ngokuxhomekeke kugqirha kunye nelebhu yakho, ke cela ugqirha wakho ukuba unengxaki.

Iziphumo zovavanyo lwe-PTT engaqhelekanga

Khumbula ukuba iziphumo ezingaqhelekanga ze-PTT azichongi nasiphi na isifo. Inika kuphela ukuqonda malunga nexesha elithathayo ukuba igazi lakho lijiye. Izifo ezininzi kunye neemeko zinokubangela iziphumo ezingaqhelekanga ze-PTT.

Iziphumo ze-PTT ezinde zinokubangelwa:

• iimeko zokuzala, njengokukhulelwa kwangoku, ukukhulelwa kwangoku, okanye ukuphuma kwesisu
• ihemophilia A okanye uB
• ukunqongophala kwezinto ezijija igazi
• Isifo se-von Willebrand (ingxaki ebangela ukungaqheleki kwegazi ngokungaqhelekanga)
• Kusasazwa i-intravascular coagulation (isifo apho iiprotheni ezijongene nokuqunjelwa kwegazi zisebenza ngokungaqhelekanga)
• i-hypofibrinogenemia (ukusilela kwegazi elijija i-fibrinogen)
• amayeza athile, anjengegazi heparin kunye newarfarin
• Imiba yesondlo, enje ngokuswela i-vitamin K kunye ne-malabsorption
• izilwa-buhlungu, kubandakanywa neentsholongwane zentliziyo
• Iilupus anticoagulants
• Ileukemia
• isifo sesibindi

Uluhlu olubanzi lwezinto ezinokubangela iziphumo ezingaqhelekanga zithetha ukuba olu vavanyo lodwa alwanele ukumisela ukuba yeyiphi imeko onayo. Iziphumo ezingaqhelekanga ziya kuthi zikhuthaze ugqirha wakho ukuba ayalele iimvavanyo ezingaphezulu.
