Qhov sib txawv tseem ceeb ntawm plasmapheresis thiab plasma pauv yog tias plasmapheresis yog txheej txheem uas cov plasma cais tawm ntawm cov ntshav los ntawm centrifugation lossis membrane filtration, thaum hloov ntshav plasma yog txheej txheem uas cuam tshuam cov plasma tag nrho thiab hloov nws. nrog cov kua hloov pauv.
Plasmapheresis thiab ntshav pauv yog ob hom apheresis. Apheresis yog ib qho kev kho mob thev naus laus zis uas cov ntshav ntawm ib tus neeg tau dhau los ntawm ib lub cuab yeej uas cais tawm cov khoom siv tshwj xeeb thiab xa rov qab rau cov khoom seem. Yog li, nws yog kev kho mob extracorporeal. Feem ntau muaj ob hom apheresis: pub dawb (plasmapheresis, erythrocytapheresis, plateletpheresis, leukapheresis) thiab kev kho (plasma exchange, LDL apheresis, photopheresis, leukocytapheresis, thiab thrombocytapheresis).
Plasmapheresis yog dab tsi?
Plasmapheresis yog txheej txheem uas cov plasma cais tawm ntawm cov ntshav los ntawm centrifugation lossis membrane pom. Plasmapheresis yog thawj zaug piav qhia los ntawm cov kws kho mob Vadim A. Yurevick thiab Nicolay Rosenberg ntawm Imperial Medical and Surgical Academy ntawm Saint Petersburg, Russia, xyoo 1913. Tsis tas li ntawd, Michael Rubinstein yog thawj tus siv plasmapheresis los kho cov kab mob tiv thaiv kab mob thaum nws cawm tau txoj sia. ntawm ib tug tub hluas uas muaj thrombotic thrombocytopenic purpura (TTP) ntawm Cedar ntawm Lebanon Tsev Kho Mob hauv Los Angeles, Tebchaws USA, xyoo 1959. Cov txheej txheem plasmapheresis niaj hnub tau tshwm sim los ntawm US National Cancer Institute ntawm xyoo 1963 thiab 1968.
Daim duab 01: Plasmapheresis
Plasmapheresis muaj txiaj ntsig hauv kev sau FFP (cov ntshav khov tshiab) ntawm ib pawg ABO tshwj xeeb. Kev lag luam siv cov txheej txheem no (sib nrug los ntawm FFP) suav nrog cov khoom lag luam immunoglobulin, plasma derivatives, thiab sau cov tshuaj tiv thaiv tsis tshua muaj WBC thiab RBC. Plasmapheresis tseem tuaj yeem xa mus rau cov txheej txheem pub dawb plasma qhov twg cov plasma raug tshem tawm, thiab cov qe ntshav rov qab mus rau lub cev. Plasmapheresis tuaj yeem siv los kho ntau yam kab mob autoimmune xws li myasthenia gravis, Guillain Barre syndrome, mob ntev demyelinating polyneuropathy, thiab Lambert Eaton myasthenic syndrome. Nws kuj tseem siv tau los kho qee yam teeb meem ntawm cov kab mob ntawm tes thiab qee hom kab mob neuropathy.
Plasma Exchange yog dab tsi?
Plasma pauv yog cov txheej txheem ntawm kev tshem cov ntshav tag nrho thiab hloov nws nrog cov kua dej hloov. Nws suav nrog kev tshem tawm cov kua dej ntawm cov ntshav kom tshem tawm cov khoom tsis zoo thiab hloov nrog cov tshuaj hloov pauv. Tom qab ntawd cov plasma tshem tawm raug muab pov tseg, thiab tus neeg mob tau txais kev hloov pauv cov ntshav ntshav, albumin, lossis kev sib xyaw ntawm albumin thiab saline (feem ntau 70% albumin thiab 30% saline). Kev kho apheresis lossis kev sib pauv ntshav ntshav yog ua raws li kev tshem tawm cov tshuaj lom ntawm cov hlab ntsha.
Daim duab 02: Plasma Exchange – (1) Tag nrho cov ntshav nkag mus rau hauv lub centrifuge thiab (2) cais mus rau hauv cov ntshav, (3) leukocytes thiab (4) erythrocytes. (5) Cov khoom xaiv tau raug rho tawm
Hauv cov txheej txheem no, ib lub catheter muab tso rau hauv cov hlab ntsha thiab txuas nrog lub tshuab ntawm cov raj yas. Cov ntshav yog pumped los ntawm cov tubing mus rau hauv lub tshuab, qhov twg nws yog cais mus rau hauv cov ntshav liab, cov qe ntshav dawb, thiab plasma. Tom qab ntawd, cov plasma raug muab pov tseg thaum lwm cov khoom sib xyaw ua ke nrog cov ntshav hloov pauv (albumin thiab saline) thiab rov ua dua rau tus neeg. Tsis tas li ntawd, kev sib pauv plasma tuaj yeem siv los ua kev kho mob rau cov kab mob rheumatic.
Dab tsi zoo sib xws ntawm Plasmapheresis thiab Plasma Exchange?
- Plasmapheresis thiab plasma pauv yog ob hom apheresis.
- Ob txheej txheem txuas nrog kev sib cais ntshav.
- Lawv qhia kev siv tshuaj kho.
- Ob txoj kev siv tau los kho ntau yam kab mob.
- Lawv yog cov txheej txheem tseem ceeb heev los tiv thaiv tib neeg lub neej.
Qhov txawv ntawm Plasmapheresis thiab Plasma Exchange yog dab tsi?
Plasmapheresis yog txheej txheem uas plasma cais tawm ntawm cov ntshav los ntawm centrifugation lossis membrane pom, thaum kev pauv ntshav yog cov txheej txheem pov tseg cov ntshav tag nrho thiab hloov nws nrog cov kua dej hloov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm plasmapheresis thiab plasma pauv. Tsis tas li ntawd, plasmapheresis yog siv rau cov hom phiaj pub dawb nrog rau cov hom phiaj kho mob, thaum hloov ntshav plasma tsuas yog siv rau kev kho mob xwb.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm plasmapheresis thiab plasma pauv hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Plasmapheresis vs Plasma Exchange
Plasmapheresis thiab ntshav pauv yog ob hom kev ua haujlwm apheresis. Plasmapheresis yog txheej txheem uas cov ntshav tau muab cais tawm ntawm cov ntshav los ntawm centrifugation lossis membrane pom, thaum hloov ntshav plasma yog cov txheej txheem pov tseg cov ntshav tag nrho thiab hloov pauv nrog cov kua dej hloov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm plasmapheresis thiab plasma pauv.
