Kungani le parameter yegazi ibalulekile?
Ngaphambi kokuba i-Rh isinqunywe ebusweni, ubukhona bomama buyaziwa. Ngempela, akubona bonke abesifazane abazi uhlobo lwabo lwegazi. Leli pharamitha liyabalwa lapho kukhulelwa kwenzeka, ngoba kukhona ithuba lokuthuthukisa into efana ne-Rh-impikiswano. Kuyabonakala uma umama enesiprotheni enikeziwe, kepha ingane ikhona. Incazelo yalesi simo yilokho ingane izuze i-Rh-antigen evela kuyise. Amathuba oku lokhu angama-75%. Ngakho-ke, ngisho nangaphambi kokuhlela ukukhulelwa, wonke owesifazane onomqondo omubi weR Rh kumele azi i-rhesus yendoda yakhe ekhethiwe. Uma kungenakuphikisana kwabo, amathuba okuthuthukiswa kwempi aphezulu, okuyinto engathinta ukukhulelwa kabi. Futhi kwezinye izimo, ukukhulelwa akukwenzeka nhlobo.
I-fetus inquma kanjani i-Rh factor?
Kuze kube yamuva, inqubo yokunquma i-Rh factor ye-fetus yayinzima kakhulu. Ukuze wenze lokhu, kwakudingeka ukuthi uqhube ucingo lwento ngokuqondile kusuka emntwaneni, okwenziwe ngendlela engavamile. Ngokwalo, ukuxhaphazwa kuyingozi kakhulu futhi kwabiwa kuphela ezimweni ezihlukile, nobufakazi obukhona.
Namuhla, inani elikhulu lemitholampilo yezokwelapha livumela abesifazane abakhulelwe ukuba babone i-Rh factor ye-fetus ngendlela engavumelekile, eyenziwa kanye nokuhlaziywa komkhuba. Ukuze unqume, kwanele ukuthatha igazi emithanjeni yomama ozayo. Ngokwenza kanjalo, uma uhlaziya i-Rh factor of the fetus, cabanga nge-DNA yengane, ekhona egazini labesifazane abakhulelwe.
Ukufundwa kwezinto eziqoqiwe kwenziwa yindlela ye-PCR, engahle ibekwe kusukela ngesonto le-12 lokukhulelwa. Lokhu kuhlaziywa kwenziwa ngesineke futhi kudinga ukuqokwa komzimba wezifo zokwelapha.
Ngaphezu kwalokho, lolu cwaningo lukuvumela ukuba unqume kalula ukuthi kukhona i-Rh-antigen enganeni, engayifumana ipapa, futhi uthole uhlobo lwegazi lomntwana, okubalulekile futhi.
Kuthiwani uma i-Rh isici sowesifazane okhulelwe nomntwana ongasifani?
Kulezo zimo lapho i-Rh factor yowesifazane engalungile, ibonakala ngesikhathi sonke sokukhulelwa. Odokotela balawula isimo se-fetus.
Ukuze kuvinjelwe ukuthuthukiswa kwezinkinga, i-antiresus immunoglobulin ihanjiswa ngenye indlela kumfazi, okusiza ukususa ama-antibodies akhiqizwa kumama njengendlela yokusabela phambi kwaleli phrotheni enganeni yakhe.
Ezimweni lapho i-Rh factor ingenakunina kumama nengane, akukho mpikiswano, ngakho-ke,
Ngakho-ke, ipharamitha efana ne-Rh factor ye-fetus inqunywa kuphela uma owesifazane okhulelwe enenani elibi. Lokhu kwenziwa ukuvimbela ukuthuthukiswa kwe- Rh-ukungqubuzana, okungaholela emiphumeleni edabukisayo, ikakhulukazi - ukukhipha isisu okuzenzekelayo. Uma lokhu kungenzeki, khona-ke isikhathi sonke sokubeletha siyabonwa ngowesifazane okhulelwe. Inqubo eyinhloko kuleli cala ukuhlolwa kwegazi lapho kunqunywe khona ukuthi amasosha omzimba akhona kunina, kuR Rhusus wezingane zakhe ezincane ezingakazalwa.
