Rh kusapindirana

Rh kusapindirana chiitiko chinokura kana mukadzi ane nhumbu aine Rh-isina ropa uye mwana ari mudumbu rake ane ropa reRh-positive.

Munguva yekuzvitakura, masero matsvuku eropa kubva kumwana asati aberekwa anogona kuyambuka achipinda muropa raamai kuburikidza nepacenta.

Kana amai vari Rh-negative, immune system yavo inobata maR-positive fetal maseru sekunge chinhu chekunze. Muviri wamai unogadzira masoja ekudzivirira fetal masero eropa. Aya maantibhakitiriya anogona kuyambuka achidzokera nepacacenta kuenda mumwana ari kukura. Vanoparadza masero matsvuku eropa emwana.

Kana masero matsvuku eropa aputswa, anoita bilirubin. Izvi zvinokonzera kuti mucheche ave yero (jaundiced). Chiyero chebilirubin muropa remucheche chinogona kubva kubva pakapfava kusvika pakakwirira zvine njodzi.

Vacheche vekutanga vacheche havawanzo kukanganiswa kunze kwekunge amai vakambobvisa nhumbu kana kubvisa nhumbu. Izvi zvaigona kukurudzira immune system yake. Izvi zvinodaro nekuti zvinotora nguva kuti amai vagadzire masoja ekudzivirira chirwere. Vese vana vaanozova navo zvakare vari Rh-positive vanogona kukanganiswa.

Rh kusapindirana kunoitika chete kana amai vari Rh-negative uye mucheche ari Rh-positive. Dambudziko iri rave kushomeka munzvimbo dzinopa rubatsiro rwekusununguka. Izvi zvinodaro nekuti akasarudzika immune globulins anonzi RhoGAM anowanzo shandiswa.

Rh kusapindirana kunogona kukonzera zviratidzo zvichibva kubva pakapfava kusvika pakuuraya. Mune fomu yayo yakapfava, kusapindirana kweRh kunokonzeresa kuparadzwa kwemasero matsvuku eropa. Iko hakuna mimwe mhedzisiro.

Mushure mekuzvarwa, mucheche anogona kunge aine:

• Kupenya kweganda uye nevachena vemeso (jaundice)
• Yakaderera mhasuru toni (hypotonia) uye kuneta

Asati asununguka, amai vanogona kunge vaine amniotic fluid yakatenderedza mwana wavo asati aberekwa (polyhydramnios).

Panogona kuve ne:

• A yakanaka yakananga Coombs bvunzo mhedzisiro
• Yepamusoro-kupfuura-yakajairwa mazinga ebilirubin mumwana wembilical tambo yeropa
• Zviratidzo zvekutsvairwa kwemasero eropa muropa remucheche

Rh kusapindirana kunogona kudzivirirwa nekushandiswa kweRhoGAM. Naizvozvo, kudzivirira kunoramba kuri kurapwa kwakanyanya. Kurapa kwemucheche anenge atokanganiswa zvinoenderana nekukura kwemamiriro acho.

Vacheche vane hunyoro Rh kusapindirana vanogona kurapwa nephotootherapy vachishandisa bilirubin mwenje. IV immune globulin inogona zvakare kushandiswa. Kune vacheche vanokanganiswa zvakanyanya, kuchinjaniswa kuwedzerwa ropa kunogona kudikanwa. Uku ndokwekuderedza nhanho dze bilirubin muropa.

Kudzoreredza kwakazara kunotarisirwa kune nyoro Rh kusapindirana.

Zvinetso zvinogona kusanganisira:

• Kukanganiswa kwehuropi nekuda kwemazinga akakwirira ebilirubin (kernicterus)
• Fluid buildup uye kuzvimba mumwana (hydrops fetalis)
• Matambudziko nekushanda kwepfungwa, kufamba, kunzwa, kutaura uye kubata

Fonera wako mupi wezvehutano kana iwe uchifunga kana uchiziva kuti une nhumbu uye usati waona mupi.

Rh kusapindirana inoda kudzivirirwa zvachose. Rh-isina amai vanofanirwa kuteverwa padyo nevanovapa panguva yekuzvitakura.

Special immune globulins, inonzi RhoGAM, yava kushandiswa kudzivirira kusawirirana kweRH mune vanaamai vari Rh-negative.

Kana baba vemucheche vaine Rh-positive kana kana rudzi rweropa rusingazivikanwe, amai vanopihwa jekiseni reRhoGAM panguva yechipiri trimester. Kana mwana aine Rh-positive, amai vanowana jekiseni rechipiri mukati memazuva mashoma mushure mekusununguka.

Aya majekiseni anodzivirira kugadzirwa kwema antibodies anorwisa Rh-positive ropa. Zvisinei, vakadzi vane Rh-negative ropa rudzi vanofanira kuwana majekiseni:

• Munguva yepamuviri pese
• Mushure mekuparara kana kubvisa nhumbu
• Mushure mekuedzwa kwepamuviri senge amniocentesis uye chorionic villus biopsy
• Mushure mekukuvara mudumbu panguva yekuzvitakura

Rh-inosimudzira hemolytic chirwere cheiye achangozvarwa; Erythroblastosis fetalis

• Achangoberekwa jaundice - buditsa

• Erythroblastosis fetalis - photomicrograph
• Jaundiced mucheche
• Antibodies
• Shanduko kuwedzerwa - akateedzana
• Rh kusapindirana - akateedzana
