Chii chinonzi Rh factor? Iyo ipuroteni iri pamusoro pemasero eropa (erythrocytes). Vanhu ivavo vane ikozvino vari vatakuri veHan factor yakanaka. Vanhu ivavo vasina puroteni iyi muropa ravo ndiRh-negative. Izvo zvakaratidzwa kuti Rh yakashata inenge 20% yevanhu.
Muchiitiko ichocho kana kusina kufanana kweamai nevana muR Rh factor, kuumbwa kwemitumbi inorwisa inogona kutanga mumutumbi wemukadzi ane pamuviri.
Uye hapana ngozi yekusawirirana muR Rh chinokonzerwa naamai nevana, kana vose amai nababa vari Rh-negative kana kuti amai vane Rh factor. Uyewo, kana mwana wacho akawana mazita ezvese zvevabereki panguva imwe chete, saka hakuna Rhesus-kukakavara.
Ndezvipi kusawirirana kweamai nemwana muR Rh factor?
Muviri wemukadzi ane pamuviri, sezvakambotaurwa, kune Rhesus-mhirizhonga, semugumisiro waro, mumuviri wemadzimai, zvirwere zveRh zvinobudiswa - mapuroteni akasiyana-siyana. Muchiitiko ichi, vanachiremba vakaisa mukadzi akaongororwa ane rhesus-senitization.
Rhesus antibodies inogonawo kuonekwa mumuviri wemukadzi mushure mokubvisa pamuviri, mushure mekuberekwa kwe ectopic, mushure mokuberekwa kwekutanga.
Zvisinei, mumatambudziko akawanda, pamuviri wokutanga mumukadzi weR Rh-negative unowedzera pasina zvinetso. Kana kuve nepamuviri kwekutanga kunoparadzaniswa, njodzi yekukudziridza Rh-kukurudziro panguva yekuzvitakura kunotevera inowedzera. Uyezve, izvi zvinorwara hazvikuvadzi kumuviri wemukadzi chero ipi zvayo. Asi, kupinda mu fetal bloodstream, zvirwere zveRhesus zvinogona kuparadza erythrocytes, zvichiita kuti anemia yemwana achangoberekwa, kuputsika kwekugadzirwa kwezvinhu zvakakosha uye nhengo dzomwana. Kukundikana kwema fetus neR Rh masimba anonzi hemolytic disease. Migumisiro yakaipa kwazvo yekusagadzikana kweamai nevana neiko rezu ndiyo kuberekwa kwomwana asingakwanisi hupenyu. Mune zviitiko zvinorema, mwana anozvarwa ane jaundice kana anemia.
Vana vanoberekwa vane zviratidzo zvehutachiona hweHemolytic vanoda chirwere chekurumidza - kuwedzerwa ropa.
Kuti udzivise migumisiro yakaoma yekusawirirana kweamai nevana muR Rh factor, unofanira kutanga utanga kubvunzurudza kwevakadzi, kwaunenge uchizoendeswa kune miedzo yose yakakodzera. Kana zvakaguma zvezviedzo zvichiratidza kuti une Rh nhengo yakashata, iwe uchaiswa pane imwe nhoroondo yakanyanyisa uye uchagara uchitarisa kuvepo kweHr antibodies muropa. Kana zvikaitika kana zvirwere zvinowanikwa, iwe uchagoverwa kune imwe nzvimbo inokosha inopesana.
Iye zvino chirwere che hemolytic che fetus chinowanikwa kare kare. Mwana anobatsirwa kuti ararame mudumbu raamai achishandisa kuisa ropa mukati mekushaya ropa. Kushandisa ultrasound kuburikidza nekunze kwemadziro emadzimai emukadzi, fetus inodururwa kuburikidza nemuviri kuenda mumbilical cord kusvika kune 50ml yemupiro wemasero matsvuku eropa, kuitira kuti mwana anowanzogara kusvikira pakupera kwekuita pamuviri.
Apo mudzimai weR Rh-negative ane mwana ane Rh factor, antiresus gamma globulin inorowa mukati-kati mumaawa mashomanana ekutanga. Nekubatsira kwechirwere ichi mumutumbi waamai, kugadzirwa kwezvirwere zvinomira.
