Polycythemia - achangoberekwa

Polycythemia inogona kuitika kana paine masero matsvuku eropa akawandisa (RBCs) muropa remucheche.

Iyo muzana yeRBCs muropa remucheche inonzi "hematocrit." Kana izvi zvakakura kupfuura 65%, polycythemia iripo.

Polycythemia inogona kukonzerwa nemamiriro ezvinhu anokura asati aberekwa. Izvi zvinogona kusanganisira:

• Kunonoka kuumbirira tambo yembilical
• Chirwere cheshuga muna amai vekubereka vemwana
• Zvirwere zvakagara nhaka uye matambudziko emajini
• Okisijeni yakawandisa inosvika mumiviri yemuviri (hypoxia)
• Twin-twin transfusion syndrome (inoitika kana ropa richifamba kubva kune rimwe mapatya kuenda kune rimwe)

Iyo yekuwedzera maRBCs anogona kudzora kana kudzivirira kuyerera kweropa mumidziyo midiki yeropa. Izvi zvinonzi hyperviscosity. Izvi zvinogona kutungamira kurufu rwekufa nekushaya oxygen. Izvi zvakavharwa kuyerera kweropa zvinogona kukanganisa nhengo dzese, kusanganisira itsvo, mapapu, uye huropi.

Zviratidzo zvinogona kusanganisira:

• Kunyanya kurara
• Matambudziko ekudyisa
• Kufenda

Panogona kuve nezviratidzo zvezvinetso zvekufema, itsvo kukundikana, shuga shoma yeropa, kana chirwere chenduru chichangozvarwa.

Kana mwana aine zviratidzo zvehyperviscosity, kuongororwa kweropa kuverenga huwandu hweRBCs kuchaitwa. Uyu muedzo unonzi hematocrit.

Mimwe bvunzo inogona kusanganisira:

• Magasi eropa kutarisa okisijeni muropa
• Ropa shuga (glucose) kutarisa yakaderera ropa shuga
• Ropa urea nitrogen (BUN), chinhu chinogadzirwa kana mapuroteni aputsika
• Creatinine
• Kuongorora urinal
• Bilirubin

Mwana anozotariswa nematambudziko e hyperviscosity. Mvura inogona kupihwa kuburikidza nemutsinga. Chikamu chekutsinhana kuwedzerwa kuwedzerwa dzimwe nguva kuchiri kuitiswa mune zvimwe zviitiko. Nekudaro, pane humbowo hushoma hwekuti izvi zvinoshanda. Izvo zvinonyanya kukosha kurapa iyo yakakonzera iyo polycythemia.

Maonero acho akanaka kune vacheche vane hunyoro hyperviscosity. Mhedzisiro yakanaka inogona zvakare muvacheche vanowana kurapwa kweakanyanya hyperviscosity. Maonero acho anoenderana zvakanyanya nechikonzero chemamiriro acho.

Vamwe vana vanogona kuve nehunyoro hwekuchinja shanduko. Vabereki vanofanirwa kubata mupi wezvehutano kana vachifunga kuti mwana wavo anoratidza zviratidzo zvekunonoka kukura.

Zvinetso zvinogona kusanganisira:

• Kufa kwematumbo matumbu (necrotizing enterocolitis)
• Yakadzora yakanaka mota kudzora
• Itsvo kutadza
• Kufenda
• Kurohwa
