Ntshav coagulation feem ntau tsis muaj nyob txawm tias nws zoo lossis phem.Ntshav coagulation muaj lub sijhawm ib txwm muaj.Yog tias nws nrawm dhau lossis qeeb dhau, nws yuav ua rau tib neeg lub cev tsis zoo.

Cov ntshav coagulation yuav nyob rau hauv ib tug tej yam li ib txwm, thiaj li tsis ua rau los ntshav thiab thrombus tsim nyob rau hauv tib neeg lub cev.Yog hais tias cov ntshav coagulation sai dhau lawm, nws feem ntau qhia tau hais tias tib neeg lub cev nyob rau hauv lub xeev hypercoagulable, thiab cov kab mob plawv thiab cerebrovascular yuav tshwm sim, xws li cerebral infarction thiab myocardial infarction, qis extremity venous thrombosis thiab lwm yam kab mob.Yog tias tus neeg mob cov ntshav coagulates qeeb dhau, nws yuav muaj kev ua haujlwm tsis zoo ntawm coagulation, ua rau cov kab mob los ntshav, xws li hemophilia, thiab thaum mob hnyav, nws yuav ua rau muaj kev sib koom ua ke thiab lwm yam kev tsis zoo.

Kev ua haujlwm zoo thrombin qhia tau hais tias cov platelets ua haujlwm zoo thiab noj qab nyob zoo.Coagulation yog hais txog cov txheej txheem ntawm cov ntshav hloov los ntawm lub xeev ntws mus rau lub xeev gel, thiab nws cov ntsiab lus yog cov txheej txheem ntawm kev hloov cov fibrinogen soluble mus rau hauv cov ntshav tsis txaus hauv fibrinogen.Hauv kev nkag siab nqaim, thaum cov hlab ntsha raug puas ntsoog, lub cev tsim cov coagulation yam tseem ceeb, uas yog qhib kom ua thrombin, uas thaum kawg hloov fibrinogen rau hauv fibrin, yog li txhawb cov ntshav coagulation.Coagulation feem ntau kuj suav nrog platelet kev ua haujlwm.

Kev txiav txim siab seb cov coagulation puas zoo los tsis yog feem ntau los ntawm kev los ntshav thiab kev sim kuaj.Coagulation dysfunction yog hais txog cov teeb meem nrog coagulation yam, txo kom muaj nuj nqis lossis txawv txav, thiab cov tsos mob los ntshav.Los ntshav tshwm sim tuaj yeem tshwm sim, thiab purpura, ecchymosis, epistaxis, los ntshav cov pos hniav, thiab hematuria tuaj yeem pom ntawm daim tawv nqaij thiab cov mucous membranes.Tom qab kev raug mob los yog kev phais, qhov ntau ntawm los ntshav nce thiab lub sij hawm los ntshav yuav ntev.Los ntawm kev tshawb pom ntawm lub sijhawm prothrombin, ib feem ntawm lub sijhawm ua haujlwm prothrombin thiab lwm yam khoom, nws pom tau tias kev ua haujlwm coagulation tsis zoo, thiab qhov ua rau kev kuaj mob yuav tsum tau qhia meej.
