Njengoko uyazi, ngexesha lokukhulelwa emzimbeni wowesifazane kukho utshintsho oluninzi oluchaphazela umsebenzi malunga nawo onke amalungu kunye neenkqubo. Igazi alikho ikhefu.
Ngaphantsi kwefuthe lenani elikhulu lama-estrogens egazini lomfazi okhulelweyo, inkqubo ye-homeostatic isoloko ihlala "kwindawo yokuqapha". Le nyaniso ibonakaliswe ngokuthe ngqo kuhlalutyo: inani le-fibrinogen egazini, i-prothrombin kunye ne-antithrombin iyanda. Ngoko ke, ngokuqhelekileyo ibhinqa lichazwe uhlalutyo lwe-D-dimer ukwenzela ukuba ukhangele ixabiso kwiimeko eziqhelekileyo okanye kukho ukuphambuka.
Yintoni "iD-dimer"?
Olu hlalutyo lusivumela ukuba sikwazi ukugxininisa kwigazi lemveliso yokuthotywa kwe-fibrinogen, ethatha inxaxheba kwinkqubo yokucima. Wena. I-D-dimer ephakamileyo ibonisa ukuba umzimba womfazi okhulelwe unamathele emacaleni egazi.
E-EU, le ndlela isetyenziselwa ukukhuphela ukuvela kwe-thrombosis. Ngoko ke, ukuba ixabiso leli phofu liyancipha okanye liloluhlu oluqhelekileyo, ngoko-ke inokuthi i-100% inokwenzeka ukuba i-thrombosis ayikho imbangela yokuphuhliswa kweemeko eziphuthumayo. Ngoko ke, ngokuqhelekileyo, iD-dimer isetyenziselwa ukuvuselelwa, xa ixesha libaluleke kakhulu.
Isilingo seD-dimer senziwa njani?
Olu hlalutyo alufani nolwahlulo lwegazi oluqhelekileyo oluvela kwimvini. Ngaphambi kokuba uthathe i-D-dimer, iiyure ezingama-12 phambi kokuba kungavunyelwe ukuba adle, kwaye uhlalutyo lwenziwe kuphela kwisisu esingenalutho.
Igazi eliqokelelweyo lihlalutya ngokuchanekileyo kweekhemikhali ngokusebenzisa izibonakaliso ezikhethekileyo ezibonisa ukuba khona okanye ukungabikho kwemveliso ye-protein degradation ye-fibrinogen. Ngokuqhelekileyo kuthatha imizuzu engama-10 ukuya ku-15 ukuya kufikelela kwisiphumo, okwenza kube lula ukuba lolu hlobo lophando luveze iimvavanyo.
Imilinganiselo kaD-dimer kubantu abanobuchule
Ngokuqhelekileyo, isiqhelo sikaD-dimer kwabasetyhini abangabathanga abantwana bahluka phakathi kwe-400-500 ng / ml. Yaye ihlala ishintsha, kwaye ixhomekeka kwisigaba somjikelezo wesini. Ngaphezulu kwama-500 ng / ml bathetha malunga nophuhliso lwe-pathology.
Imilinganiselo yeD-dimer ekukhulelweni
Umgangatho weD-dimer ngokuthe ngqo kuxhomekeke kwixesha lokukhulelwa kwaye utshintshe ngokuqala kwekota elandelayo. Ngoko ngokuqhelekileyo kwi-trimester yokuqala le ncwadana inyuselwa ngamaxesha ama-1.5 kwaye inokuthatha ixabiso elilingana no-750 ng / ml. Ukuqhubela phambili kunye nokwanda kwekota, ixabiso liye litshintshe kwicala elikhulu.
Kwimizuzu yesi-2 ixabiso le-D-dimer lingakwazi ukufikelela kuma-1000 ng / ml, kwaye ekupheleni kwekota-ukwanda ngamaxesha amathathu xa kuthelekiswa nomgangatho, - ukuya ku-1500 ng / ml.
Ukuba ixabiso le-D-dimer lidlulile ezi xabiso, ngoko bathetha ngokuxhomekeka kwi-thrombosis.
Iimpawu zeD-dimer kwi-IVF
Kwiimeko ezininzi, ii- IVF zenziwa yinkqubo yokugqithisa, okukhokelela ukwandisa kwi-estrogens egazini. Ukunyuka kwabo kunokuvusa ukuphuhliswa kwe-thrombosis kwabasetyhini. Ngako oko, ukuqhuba rhoqo ukuhlolwa kwegazi ku-D-dimer, ekule meko idlala indima yemakishi, ibaluleke kakhulu.
Ngokuqhelekileyo, emva kwe-IVF ephumeleleyo, izinga elithile lezinga le-D-dimer liyaqaphela. Nangona kunjalo, ixabiso lalo lifaniswa nezo zinto zibonakalisa igazi labesetyhini abakhulelwe ngokwemvelo.
Ngaloo ndlela, uhlalutyo lwe-D-dimer luyindlela efanelekileyo kakhulu yophando lwebhubhoratri, oluya kuphelisa ngokupheleleyo uphuhliso lwe-thrombosis, olufuna unyango olukhawulezayo kwaye luhlala lukhokelela ekuphuculweni kweemeko zongxamiseko. Ngoko ke, onke amabhinqa akhulelweyo kufuneka athathe olu hlalutyo, olunceda ukuchonga ukuphulwa kwenkqubo ye- clotting system.
