Polycythemia - yug menyuam tshiab

Polycythemia tuaj yeem tshwm sim thaum muaj ntau cov ntshav liab nyob hauv cov ntshav liab ntawm cov ntshav liab.

Qhov feem pua ​​ntawm RBCs hauv cov ntshav ntawm tus menyuam mos yog hu ua "hematocrit." Thaum qhov no loj dua 65%, polycythemia tam sim no.

Polycythemia tuaj yeem tshwm sim los ntawm cov kev mob uas ua ntej yug. Cov no suav nrog:

• Ncua hauv clamping lub txoj hlab ntaws
• Mob ntshav qab zib hauv tus menyuam lub menyuam niam
• Tau cov kab mob thiab caj ces muaj teeb meem
• Tsawg cov pa oxygen ncav cuag lub cev nqaij (hypoxia)
• Ntxaib Hloov Cov Ntxaib (tshwm sim thaum cov ntshav txav los ntawm ib tus menyuam ntxaib mus rau lwm qhov)

RBCs ntxiv tuaj yeem ua kom qeeb los yog txhaws cov ntshav hauv cov ntshav me tshaj plaws. Qhov no hu ua hyperviscosity. Qhov no tuaj yeem ua rau cov nqaij mos tuag vim tias tsis muaj oxygen. Qhov ntshav ntws uas cuam tshuam no yuav cuam tshuam rau txhua yam hauv nruab nrog cev, nrog rau ob lub raum, lub ntsws, thiab lub hlwb.

Cov tsos mob tuaj yeem suav nrog:

• Tsaug zog heev
• Pub teeb meem
• Qaug dab peg

Tej zaum nws muaj cov cim ntawm kev ua pa nyuaj, lub raum tsis ua haujlwm, ntshav qab zib qis, lossis nqaij tawv tshiab.

Yog tias tus me nyuam muaj cov tsos mob ntawm hyperviscosity, kuaj ntshav kom suav tus lej RBCs yuav ua. Qhov kev kuaj no yog hu ua hematocrit.

Lwm yam kev ntsuam xyuas yuav suav nrog:

• Ntshav cov roj txhawm rau kuaj cov pa theem hauv cov ntshav
• Ntshav qab zib (piam thaj) mus kuaj ntshav qab zib kom qis
• Ntshav urea nitrogen (BUN), uas yog cov tshuaj tshwm sim thaum cov protein zom zom
• Neej Khuam Siab
• Mob Lub Hlaus
• Bilirubin

Tus me nyuam yuav raug saib xyuas rau qhov kev mob ntawm hyperviscosity. Yuav muab cov kua dej los ntawm txoj leeg ntshav. Qee lub sij hawm hloov cov ntshav ntxiv qee zaum kuj tseem ua qee kis. Txawm li cas los xij, tsis muaj pov thawj me me tias qhov no ua haujlwm. Nws yog ib qho tseem ceeb tshaj plaws los kho lub hauv paus chiv mob ntawm polycythemia.

Qhov kev xam pom yog qhov zoo rau cov menyuam mos nrog hyperviscosity me. Cov txiaj ntsig zoo kuj tseem muaj peev xwm ua tau rau cov menyuam mos uas tau txais kev kho mob rau mob ntshav siab. Lub zeem muag yuav cia siab rau qhov laj thawj ntawm tus mob.

Qee tus me nyuam yuav muaj qhov kev hloov ntawm kev loj hlob me. Cov niam txiv yuav tsum hu rau lawv tus kws saib xyuas kev noj qab haus huv yog tias lawv xav tias lawv tus menyuam muaj qhia qeeb qeeb ntawm kev txhim kho.

Teeb meem yuav suav nrog:

• Tuag ntawm cov nqaij hnyuv (necrotizing enterocolitis)
• Kev tsav tsheb tsis zoo
• Raum tsis ua haujlwm
• Qaug dab peg
• Mob stroke
