Coagulation: kuyinsakavukela kanye nokusuka

Coagulation kwegazi noma hemostasiogram, kokuba uhlobo ukuhlolwa igazi uqhutshwa ukufunda ekunqandeni yayo. Lokhu kuhlaziya inikezwa uma imisebenzi, abahlangene ukopha, kanye sizibone anomalies ekunqandeni njengoba ziyancipha futhi yanda, okungase kubangele izifo ezihlukahlukene, ezifana thromboses, ukuhlaselwa isifo senhliziyo noma unhlangothi.

Coagulation, okuvame Okulotshiweyo okwethulwa amatafula ekhethekile echaza isimiso sokujikeleza kwegazi futhi ukuhlaziywa yayo ku hemostasis, uvumela ukucacisa ukushayisana kwe-plasma.

Ngakho, hemostasiogram - ucwaningo oludingekayo ekukhulelweni, phambi imisebenzi ehlukahlukene e kwesikhathi nasezinkingeni ezilandela ngemva kokuhlinzwa, nge varicose emithanjeni, izifo sokuhlasela kwamasosha omzimba nezifo kwesibindi.

Ikhono ukugcina unomphela ewuketshezi futhi ngesikhathi esifanayo ukwakha ukuqeda amahlule, uma kunesidingo, uma uhlelo hemostatic emzimbeni. Noma yimuphi iziyaluyalu ukopha kungaholela emiphumeleni engathí sina.

Hemostasis kuyinto izici ezithile, okuyinto kunqunywa izifundo laboratory. Ngakho hemostasis eyinhloko kungaba azimisele: i-platelet ukubala, ubude ukopha, platelet wokuhlanganisa futhi adhesion, ukusabela ihlule legazi ezinye izinkomba. Ngo hemostasis yesibili ukunquma isikhathi wegazi coagulation, pti, APTT, fibrinogen ubuningi nokunye.

Ngakho, ngesikhathi sokukhulelwa coagulation (bokuphila kuyinsakavukela) show lenyuka igazi ekunqandeni, okuyinto akufanele kube yizona zinto lapha.

Ake sihlole kabanzi lokho ubhekwa imingcele evamile kulolu cwaningo.

1. Isikhathi ukopha. Ngokuvamile, ukopha eyeka ngomzuzu yesithathu ngemva wokubhoboza. Ukwandisa le nkathi kungase kubonise amavithamini, ukwehlisa platelet count.

2. Platelet wokuhlanganisa futhi adhesion. Coagulation (kuyinsakavukela) - adhesion - 50% futhi uquqaba - 20%. Ukwanda ngalezi zinkomba angase abhekisele ukuthuthukiswa isifo sokuqina kwemithambo yegazi, thrombosis, isifo sikashukela, noma isifo senhliziyo.

3. isihoxiso ihlule legazi. Ngokuvamile sokuhoxisa amazinga isukela amane nesishiyagalombili ukuba amaphesenti ayisithupha nane.

4. Isikhathi igazi coagulation. Coagulation (kuyinsakavukela) ngoba igazi emithambo yegazi - kusuka imizuzu emihlanu kuya kweyishumi for capillary igazi - kusukela imizuzwana amathathu amaminithi amahlanu.

Ukwandisa isikhathi ozimele idatha kungase kubonise khona kule anticoagulant igazi noma ukuthuthukiswa isifo sesibindi noma hemophilia. isikhathi ukunciphisa kungabonakala nasemkhakheni ukopha ezinzima.

5. PB (naiboleee cwaningo ebalulekile coagulogram). Kungaba azimisele ngesisekelo lesi ukuhlaziywa, izifo emathunjini futhi isibindi. Coagulation (evamile) pti - kusuka ezintathu eyodwa namashumi ayisishiyagalolunye nesikhombisa per cent, kuyilapho ngesikhathi prothrombin - kusukela nanye amasekhondi nanhlanu. Ukwanda ngalezi zinkomba angase abhekisele ukuthuthukiswa thrombosis, kodwa kwezinye izimo kuyinkomba of yokwamukela nokukhandela imbeleko.

6. fibrinogen. Ngokuvamile, leli nani kuhluka emibili kuya kwemine amagremu / ilitha. ushintsho wakhe usikisela inyumoniya, ukuvuvukala, unhlangothi, ukusha, isifo sokusha kwesibindi, isifo sokuqina kwesibindi, inhliziyo nokunye.

7. APTT. Ngokuvamile, leli nani kulingana imizuzwana amathathu noma amane. Kufanele kuqashelwe ukuthi ukuncishiswa kube inkomba yokuthi igazi ekunqandeni ukuba amaphesenti amane ezingeni APTT kuzohluka. Nokho, Enye inkomba kungase kubonise ukuthuthukiswa isifo sesibindi, hemophilia kanye nezinye izifo.

Ngakho, inqubo coagulation kuyinto ukusabela ezintathu oxhumene: zangaphakathi nezangaphandle igazi ekunqandeni, kanye nokuguqulwa fibrinogen ukuze fibrin.
