RH factor: wena nosana lwakho

Ukuba umntwana uzelwe igazi RH-HIV, unina - negative-RH, ngoko ke ukuhlanganiswa inokuba yingozi enkulu kubomi wosana. RH into unobangela yande kwaye kaninzi kabuhlungu isifo abantwana abaselula - haemolysis olungekazalwa.

Indlela of action Rhesus
Kutheni na le sifo kukhokelela ekufeni umntwana? Xa iiseli ezibomvu uninzi lwabantu, bobabini abasetyhini kunye namadoda, ke RH into. Abantu abanjalo kuthiwa "RH-positive". Abo bantu zigazi lazo awuqulathanga i RH ngumba (ka-5-15%), ingqalelo i "-ezimbi RH". Ukuba abo igazi negative-RH lazo lingeniswa adibane ngegazi RH-HIV, umzimba uqala ukuvelisa ngenkuthalo iimolekyuli - omzimba ahlasela nemiphumo emibi igazi lomntu RH-HIV.
Oku yindlela zendalo zethu amajoni omzimba, eli liyithweleyo umsebenzi lokuhlasela amazwe "bahlaseli." Apha kukho ingozi yokuba umntwana - ilifa RH factor kayise wakhe, nto leyo eye igazi RH-HIV. Ukuba ngu ukuqondana, unina uhlobo lwegazi negative-RH, ngoko ke unina angaqala ukwakha izilwa-buhlungu kunye abe bayakuqonda.
Njengoko omzimba ungakwazi ukungena egazini?
Ngokusesikweni, kukho umqobo yendalo phakathi kwegazi sikanina kunye negazi umntwana wakhe ongekazalwa - igazi labo akufuneki ihlale. Noko ke, loo nto yenzeke ngexesha iinkqubo zonyango, xa imali encinci yegazi olungekazalwa nonina uwele ngumkhaya. Umzekelo, ukwenza iisampuli ulwelo ukusuka inwebu kwisinyi (amniocentesis) kunokubangela ekulweni le ukhusela.
Ngoku umama antibodies eziza kuqhubeka esilimaza koonyana bonke ukukhulelwa emva, ukuba ilifa igazi RH-HIV likayise. ukukhulelwa nganye ezilandelayo kwandisa umngcipheko isiphumo esibi - isifo hemolytic usana.
Nangona isuntswana izilwa udlule iplacenta usana ukwenza okukwazi yexeshana ezifunyenwe zivela kunina.
Uthintelo - indlela ephumelelayo
Indlela esebenza ukungenisa kungena koomama eziphilayo antisera ethile ebizwa ngempumelelo RH immunoglobulin equlathe izilwa xandzukela iantigens Rhesus-HIV. Le ndlela isebenza ngokwenene, nto leyo inceda ukuthintela isifo. Omzimba ye- serum babhubhise zonke eyangena iiseli sikanina umzimba RH-HIV egazini elibomvu yaye ngaloo ndlela ekupheliseni ingozi yokuba umntwana ongekazalwa - umzimba yomfazi ayisa kwasekwa omzimba ezinjalo. Eneneni kwaba iqhalo lokwenyaniso eqhelekileyo phakathi koogqirha: "Kulungile ukuthatha gram yothintelo, kunokuba kwekilogram afumane unyango."
Kubaluleke kangakanani na ukuzimisela RH-factor
Ukuze ubone RH into, ukuqhuba uvavanyo yesiqhelo igazi kwanele.
Ngokutsho manani, kuphela omnye kwimitshato ezisixhenxe ludibaniso eyingozi: uyise RH-akhabayo kunye navumelanayo-RH unina. Kwakhona, ukuba umntu olungekazalwa igazi RH-HIV isuke kumama negative-RH kuxhomekeke ufuzo uyise 50-100%.
Ngokuqhelekileyo, umntwana wokuqala ayikho enkulu ingozi ugula sisifo hemolytic ukuba phambi emzimbeni kamama ntoni ukungena igazi (gazi okanye ezifana.). Kukho oomama banabantwana abahlanu babe igazi RH-HIV, kodwa ayizange ava umfazi, lo gama enye kunokuba yingozi nkqu ukukhulelwa.
Isaziso Elibalulekileyo iintsapho abo ungquzulwano RH factor: Ukuba umfazi uye ava, ngoko nokuba izithuba kunye nokoyikiswa ekufeni rhesus-ungquzulwano umbungu nganye ezilandelayo yi-30%, xa umntwana uya kulidla ilifa igazi RH-HIV.
Ngoko ke, zama ukuba ukukucekisa oko, thetha nogqirha wakho uze uye ekliniki kokubeleka ngexesha lokukhulelwa. Khusela umntwana wakho ukususela iingozi ezinokubangelwa "ingxabano" RH into.
