Cov ntshav ncig thoob plaws hauv lub cev, muab cov khoom noj txhua qhov chaw thiab tshem tawm cov khoom pov tseg, yog li nws yuav tsum tau tswj xyuas raws li qhov xwm txheej.Txawm li cas los xij, thaum cov hlab ntsha raug mob thiab tawg, lub cev yuav tsim cov tshuaj tiv thaiv, nrog rau vasoconstriction kom txo cov ntshav poob, platelet aggregation los thaiv lub qhov txhab kom tsis txhob los ntshav, thiab ua kom cov coagulation yam tseem ceeb los tsim kom muaj kev ruaj khov thrombus los thaiv. ntshav tawm thiab Lub hom phiaj ntawm kev kho cov hlab ntsha yog lub cev hemostasis mechanism.
Yog li, lub cev hemostatic nyhuv tuaj yeem muab faib ua peb ntu.Thawj feem yog tsim los ntawm kev sib cuam tshuam ntawm cov hlab ntsha thiab platelets, uas yog hu ua thawj hemostasis;qhov thib ob yog qhov ua kom muaj coagulation yam, thiab tsim cov reticulated coagulation fibrin, uas qhwv cov platelets thiab ua ib tug ruaj khov thrombus, uas yog hu ua theem nrab hemostasis, uas yog dab tsi peb hu ua coagulation;Txawm li cas los xij, thaum cov ntshav nres thiab tsis ntws tawm, lwm qhov teeb meem tshwm sim hauv lub cev, uas yog, cov hlab ntsha raug thaiv, uas yuav cuam tshuam rau cov ntshav, yog li qhov thib peb ntawm hemostasis yog qhov cuam tshuam ntawm thrombus. Thaum cov hlab ntsha ua tiav cov txiaj ntsig ntawm hemostasis thiab kho, cov thrombus yuav yaj kom rov ua kom cov hlab ntsha du.
Nws tuaj yeem pom tias coagulation yog ib feem ntawm hemostasis.Lub cev hemostasis yog qhov nyuaj heev.Nws tuaj yeem ua tau thaum lub cev xav tau nws, thiab thaum cov ntshav coagulation tau ua tiav nws lub hom phiaj, nws tuaj yeem yaj cov thrombus hauv lub sijhawm tsim nyog thiab rov zoo.Cov hlab ntsha tsis raug thaiv kom lub cev ua haujlwm tau zoo, uas yog lub hom phiaj tseem ceeb ntawm hemostasis.
Feem ntau cov ntshav los ntshav poob rau hauv ob pawg hauv qab no:
ua
1. Cov hlab ntsha thiab platelet txawv txav
Piv txwv li: vasculitis lossis platelets tsawg, cov neeg mob feem ntau muaj qhov me me los ntshav hauv qis qis, uas yog purpura.
ua
2. Qhov txawv txav coagulation yam
Xws li cov hemophilia congenital thiab Wein-Weber tus kab mob los yog kis tau daim siab cirrhosis, nas lom, thiab lwm yam, muaj feem ntau loj-scale ecchymosis me ntsis nyob rau hauv lub cev, los yog sib sib zog nqus cov leeg nqaij hemorrhage.
Yog li ntawd, yog tias koj muaj qhov txawv txav los ntshav saum toj no, koj yuav tsum mus ntsib kws kho mob hematologist sai li sai tau.
