Ukuze uqhubeke nokubeka esweni imeko yomfazi, oogqirha benyanga banikezela iimvavanyo eziliqela-ezinye izifundo zenziwa kuphela kanye, ezinye zicwangciselwe ukuhanjiswa rhoqo ngenyanga. Olunye uphando olunjalo luvavanyo lwegazi lwe-D-dimer ekukhulelweni, okukunceda ukugqiba umgangatho walo kwaye ukuchonga ubukho okanye ukungabikho kwamacandelo egazi ukukhusela i-thrombosis, kwaye ngenxa yoko, ukuvalwa kweemvini. Ngenxa yesiphumo sokuvavanya kakubi, ugqirha akafaki i-thrombosis. Ukuba isiphumo siphumelele, kwenziwe uphando olongezelelweyo ukufumana isizathu esinokwenzeka. Ukuxilongwa ngexesha kunye nokuthintela i-thromboembolism kunye ne-DIC (isifo se-coagulation ye-vascular coagulation), kuyimfuneko ukuvavanya iD-dimer ibhinqa ngalinye ngexesha lokukhulelwa.
Yintoni i-D-dimer?
Abasetyhini abaninzi abayazi nokuba i-D-dimer ivela okanye yintoni. Oogqirha bachaza: ukwenzela ukukhusela izifo ezinjenge-vein thrombosis, isifo sesifo, isifo sikashukela kunye ne-pulmonary embolism, kubalulekile ukuba uhlalutye kumgangatho we-D-dimer ekukhulelweni.
Ngaphantsi kweempembelelo zokuthinteka ngexesha lokugcoba kwe-fibrin yegazi, eyayiqulunqa kwi-plasma, ibopha kwiindonga zeempahla. Xa i-fibrin idibene, i-D-dimers yenziwa ngamabhinqa akhulelweyo. Uhlalutyo lwe-D-dimer ekukhulelweni kusetyenziswa rhoqo ukufundisisa i-coagulogram, kuba isakhiwe emzimbeni kuphela phantsi kwemeko yemvelaphi yale nkqubo mibini.
I-D-dimer ekukhulelweni yi-enzyme yeprotheni eyenza ngexesha lokuchithwa kwe-clot yegazi eyenzekayo xa igazi liphelile. Ezi ziqwenga ze-fibrin cleavage, ngokweziphumo zokuhlolwa kwegazi, zinokumisela umngcipheko we-thrombosis. Ubomi beD-dimers abukho ngaphezu kweeyure ezingama-6.
Uhlalutyo lukaD-dimer ekukhulelweni
Ukufunyanwa kwamanqanaba e-D-dimer ekucwangciseni ukukhulelwa kubaluleke kakhulu, ekubeni ukuphambuka kwakhe okuqhelekileyo kuyingozi kumfazi okhulelwe kunye nomntwana kwaye uphethwe zizifo ezifana ne-preeclampsia kunye ne- gestosis . Ukuba uphawu lwakhe egazini lomama elizayo linyuka - lithetha ukuba igazi likhulu, kwaye liyakwenza i-microthrombi, ukuvala i-capillaries, okubangele ukujikeleza kwegazi okungeyiyo kwi-uterus. Ekuqaleni ukuphambuka kufunyenwe, kuya kuba lula ukuphepha iingxaki.
I-Immunoturbidimetry yindlela yokufumana ubungakanani beD-dimer. Ukuze ulungiselele ngokufanelekileyo isifundo ofunayo:
- Ungadli ukutya okunamafutha 24 iiyure phambi kovavanyo;
- Ukukhuphela ngaphandle kweemvakalelo kunye nomzimba ngaphezu kwesigama seyure ngaphambi kokuhlalutya;
- Musa ukutshaya ngaphambi kokunikela igazi imizuzu engama-30.
D-dimer - yintoni eqhelekileyo ngexesha lokukhulelwa?
Isiqhelo sesalathisi seD-dimer egazini ngexesha lokukhulelwa akufanele sibe ngaphezu kwama-248 ng / ml. Ngethuba lesigxina "esithakazelisayo" somfazi, esi sibonakaliso sinokunyuka ngamathathu okanye amaxesha amane. I-index ephakamileyo ye-D-dimer ekukhuleleni ivumelekile. Oku kubangelwa ukuba utshintsho oluphawulekayo luvela kwinkqubo ye-hemostatic ngenxa yokusebenza komzimba kwenkqubo yokucima.
Kukholelwa ukuba kwi-trimester yokuqala, izinga le-D-dimer landa ngokuphindwe kwesinye nesigamu, kwi-trimester yesibili, njengesiqingatha sesithathu-amaxesha amathathu (angabi ngaphezu kwe-1500 ng / ml), xa kuthelekiswa nezinga eliqhelekileyo. Sichaza ixabiso eliphezulu, ngoko ke ukuba iindidi ze-D-dimer (d-dimer) ziphantsi okanye ziphantsi ekukhulelweni, zixhomekeke kumgangatho oqhelekileyo, ungakhathazeki.
UD-dimer ekukhulelwe IVF
Kufuneka kuqatshelwe ukuba iziyobisi ezibekwe ngexesha le- IVF zikhuthaza ukukhula kweD-dimer ekukhulelweni. Ngoko ke, kuyimfuneko ngexesha le-IVF ukujonga i-hemostasis egazini lomfazi okhulelweyo.
