Kev faib tawm thiab kev piav qhia ntawm lub tshuab nqus tsev sau cov hlab ntshav
1. Cov hlab ntsha hauv cov ntshav muaj lub hau liab, thiab lub raj xa ntshav tsis muaj cov tshuaj ntxiv.Nws yog siv rau niaj hnub serum biochemistry, ntshav txhab nyiaj thiab serology ntsig txog kev kuaj.
2. Lub txiv kab ntxwv-liab cap ntawm lub vas nthiv lub raj muaj coagulant nyob rau hauv lub raj sau cov ntshav kom ceev cov txheej txheem coagulation.Lub raj xa dej nrawm tuaj yeem coagulate cov ntshav uas tau sau tseg hauv 5 feeb, uas yog tsim rau kev kuaj ntshav thaum muaj xwm txheej ceev.
3. Golden cap ntawm inert separating gel coagulation raj, thiab inert separating gel thiab coagulant yog ntxiv rau hauv cov ntshav sau raj.Tom qab cov qauv yog centrifuged, lub inert sib cais gel tuaj yeem cais cov kua dej (cov ntshav los yog cov ntshav) thiab cov khoom sib xyaw (cov ntshav liab, cov qe ntshav dawb, platelets, fibrin, thiab lwm yam) hauv cov ntshav thiab tag nrho hauv nruab nrab ntawm cov ntshav. lub xeem raj los tsim ib tug barrier.Cov qauv yog nyob rau hauv 48 teev kom nws ruaj khov.Lub coagulant tuaj yeem ua kom nrawm nrawm ntawm cov txheej txheem coagulation thiab ua kom cov txheej txheem coagulation, uas tsim nyog rau kev kuaj ntshav biochemical thaum muaj xwm txheej ceev.
4. Lub hau ntsuab ntawm heparin anticoagulation raj, nrog heparin ntxiv rau hauv cov hlab ntshav.Heparin ncaj qha muaj cov txiaj ntsig ntawm antithrombin, uas tuaj yeem ua rau lub sijhawm ua ntshav khov ntawm cov qauv.Nws yog tsim rau kev kuaj ntshav liab fragility, kuaj ntshav roj, kuaj hematocrit, erythrocyte sedimentation tus nqi thiab kev txiav txim siab dav dav biochemical, tsis haum rau kev kuaj ntshav coagulation.Cov tshuaj heparin ntau dhau tuaj yeem ua rau muaj cov qe ntshav dawb thiab tsis tuaj yeem siv los suav cov qe ntshav dawb.Nws tsis haum rau kev faib cov qe ntshav dawb vim tias nws tuaj yeem stain cov ntshav hla nrog lub teeb xiav tom qab.
5. Lub teeb ntsuab lub taub hau ntawm lub plasma cais tube, ntxiv lithium heparin anticoagulant rau hauv inert sib cais hose, tuaj yeem ua tiav lub hom phiaj ntawm kev sib cais ntawm cov ntshav sai sai, nws yog qhov kev xaiv zoo tshaj plaws rau kev kuaj xyuas electrolyte, thiab tseem tuaj yeem siv rau niaj hnub plasma biochemical. kev txiav txim siab thiab
ICU thiab lwm yam kev kuaj ntshav plasma biochemical thaum muaj xwm ceev.Cov qauv ntshav tuaj yeem muab tso ncaj qha rau ntawm lub tshuab thiab khaws cia ruaj khov rau 48 teev nyob rau hauv tub yees.
6. EDTA anticoagulation tube ntshav cap, ethylenediaminetetraacetic acid (EDTA, molecular hnyav 292) thiab nws cov ntsev yog ib qho amino polycarboxylic acid, uas muaj peev xwm ua tau zoo chelate calcium ions hauv cov ntshav kuaj, chelate calcium los yog react calcium Kev tshem tawm ntawm qhov chaw yuav thaiv thiab txiav. cov txheej txheem endogenous lossis exogenous coagulation, yog li tiv thaiv cov qog ntshav los ntawm kev txhaws.Haum rau kev kuaj hematology dav dav,
Nws tsis tsim nyog rau kev kuaj ntshav coagulation thiab platelet ua haujlwm, tsis yog rau kev txiav txim siab ntawm calcium ion, potassium ion, sodium ion, hlau ion, alkaline phosphatase, creatine kinase thiab leucine aminopeptidase thiab PCR test.
7. Lub raj tshuaj sodium citrate coagulation muaj lub teeb xiav lub hau.Sodium citrate feem ntau yog siv los tiv thaiv coagulation los ntawm chelate nrog calcium ions hauv cov ntshav.Nws yog qhov tsim nyog rau kev sim ntshav coagulation.Qhov concentration ntawm anticoagulant pom zoo los ntawm Standardization Committee ntawm National Clinical Laboratory yog
3.2% los yog 3.8% (sib npaug rau 0.109mol / L los yog 0.129mol / L), qhov piv ntawm anticoagulant rau ntshav yog 1: 9.
8. Sodium citrate erythrocyte sedimentation rate test tube, black head cover, the sodium citrate concentration xav tau rau erythrocyte sedimentation rate test yog 3.2% (sib npaug rau 0.109mo/u), qhov piv ntawm anticoagulant rau ntshav yog 1: 4.
Potassium oxalate / sodium fluoride grey hau npog.Sodium fluoride yog ib qho tsis muaj zog tiv thaiv coagulant.Feem ntau, potassium oxalate lossis sodium diiodate yog siv ua ke.Qhov piv yog 1 feem ntawm sodium fluoride thiab 3 qhov chaw ntawm potassium oxalate.4mg ntawm qhov sib tov no tuaj yeem tiv thaiv 1m ntawm cov ntshav los ntawm coagulating thiab inhibit qab zib decomposition hauv 23 hnub.Nws yog ib qho tshuaj zoo rau kev txiav txim siab ntshav qabzib.Nws tsis tuaj yeem siv rau kev txiav txim siab ntawm urea los ntawm txoj kev urease, thiab nws tsis siv rau kev txiav txim siab ntawm alkaline phosphatase thiab amylase.Pom zoo rau kev kuaj ntshav qabzib.
