Nthawi yapadera ya thromboplastin (PTT)

Nthawi yapadera ya thromboplastin (PTT) ndi kuyesa magazi komwe kumayang'ana momwe zimatengera magazi kuti atseke. Itha kukuthandizani kudziwa ngati muli ndi vuto lakutaya magazi kapena ngati magazi anu sawumitsa bwino.

Kuyezetsa magazi kofananira ndi nthawi ya prothrombin (PT).

Muyenera kuyesa magazi. Ngati mukumwa mankhwala aliwonse opatulira magazi, mudzayang'aniridwa ngati muli ndi magazi.

Wothandizira zaumoyo wanu akhoza kukuwuzani kuti musiye kumwa mankhwala omwe angakhudze zotsatira zanu. Onetsetsani kuti mukuwuza omwe akukuthandizani za mankhwala onse omwe mumamwa. Komanso auzeni omwe akukupatsani mankhwala azitsamba omwe mungamwe.

Pamene singano imayikidwa kuti ikoke magazi, anthu ena amamva kupweteka pang'ono. Ena amangomva kubaya kapena kuluma. Pambuyo pake, pakhoza kukhala kupunduka kapena kuvulala pang'ono. Izi posachedwa zichoka.

Mungafunike kuyesaku ngati mukukumana ndi mavuto otaya magazi kapena magazi anu sawumitsa bwino. Mukamatuluka magazi, zochitika zingapo zomwe zimakhudza mapuloteni osiyanasiyana (zinthu zowumitsa) zimachitika mthupi zomwe zimathandiza magazi kuundana. Izi zimatchedwa coagulation cascade. Kuyesa kwa PTT kumayang'ana ma protein kapena zinthu zina zomwe zikukhudzana ndi njirayi ndikuyesa kuthekera kwawo kuthandizira magazi.

Mayesowo amathanso kugwiritsidwa ntchito kuwunika odwala omwe akutenga heparin, wochepetsetsa magazi.

Kuyesedwa kwa PTT nthawi zambiri kumachitika ndi mayeso ena, monga mayeso a prothrombin.

Mwambiri, kuwundana kumayenera kuchitika pasanathe masekondi 25 mpaka 35. Ngati munthuyo akumwa mankhwala ochepetsa magazi, kuunditsa magazi kumatenga nthawi yochuluka mpaka kawiri ½.

Mitengo yamtengo wapatali imatha kusiyanasiyana pakati pama lab. Ma lab ena amagwiritsa ntchito miyeso yosiyana kapena amatha kuyesa mitundu yosiyanasiyana. Lankhulani ndi omwe akukuthandizani za tanthauzo la zotsatira zanu zoyeserera.

Zotsatira zachilendo (zazitali kwambiri) za PTT zitha kukhalanso chifukwa cha:

• Kusokonezeka kwa magazi, gulu la mikhalidwe momwe muli vuto ndi njira yotseka magazi
• Kusokonezeka komwe mapuloteni omwe amaletsa magazi kugwiranso ntchito (amafalitsa kupindika kwa magazi m'mitsempha)
• Matenda a chiwindi
• Zovuta kutenga zakudya m'thupi (malabsorption)
• Mavitamini K ochepa

Pali chiopsezo chochepa chotenga magazi anu. Mitsempha ndi mitsempha imasiyana mosiyanasiyana kuchokera pa munthu wina kupita kwina, komanso kuchokera mbali imodzi ya thupi kupita mbali inayo. Kupeza magazi kuchokera kwa anthu ena kumatha kukhala kovuta kuposa ena.

Zowopsa zina zomwe zimakoka magazi ndi zochepa, koma mwina ndi izi:

• Kukomoka kapena kumva mopepuka
• Hematoma (magazi akuchuluka pansi pa khungu)
• Ma punctures angapo kuti mupeze mitsempha
• Kutenga (chiopsezo chochepa nthawi iliyonse khungu likasweka)

Kuyesaku kumachitika nthawi zambiri kwa anthu omwe atha kukhala ndi mavuto otaya magazi. Kuopsa kwawo kotaya magazi ndikokwera pang'ono kuposa momwe kulili kwa anthu omwe alibe mavuto otaya magazi.
