Kutheni le parameter yegazi ibalulekile?
Ngaphambi kokuba iR Rh icaciswe kwi-fetus, ubukho bomama buyaziwa. Emva koko, abafazi bonke abazi uhlobo lwabo lwegazi. Le pharamitha ithathwa ingqalelo xa kukhulelwa kwenzeka, kuba kukho amathuba okuphuhlisa into efana ne-Rh-conflict. Kuyabonakala ukuba unina uneprotheyini enikwe, kodwa umntwana ukhona. Inkcazo yale ngxaki yinto yokuba umntwana uzuze iRh-antigen evela kubaba. Ubungakanani beli 75%. Ngoko ke, nangaphambi kokucwangcisa ukukhulelwa, wonke umfazi ophethe i-Rh ingxaki kufuneka azi i-rhesus yendoda yakhethiweyo. Xa bengangqinelani, ukuphuhliswa kwemibambano kuphezulu, okuya kubachaphazela kakubi ukukhulelwa. Kwaye kwezinye iimeko, ukukhulelwa akukwenzeki nhlobo.
Umntwana usenza njani i-Rh?
Kuze kube kutshanje, inkqubo yokumisela iR Rh ye-fetus yayinzima kakhulu. Ukwenza oku, kwakudingeka ukuba uqhube ucingo lwamaxwebhu ngqo ukusuka kwintsana, eyenziwa ngendlela engenayo. Ngokwalo, ukuphathwa kakubi kwaye kunikwe kuphela kwiimeko ezizodwa, ngobungqina obukhoyo.
Namhlanje, inani elikhulu leeklinikhi zonyango livumela abafazi abakhulelweyo ukuba baqaphele iR Rh ye-fetus ngendlela engavumelekanga, eyenziwa kunye nokuhlalutya rhoqo. Ukumisela, kunele ukuthatha igazi kwiimvini zomama ozayo. Ngokwenza njalo, xa uhlalutya iR Rh ye-fetus, qwalasela i-DNA yomntwana, ekhoyo kwigazi lomfazi okhulelweyo.
Ukufundwa kwezinto eziqokelelweyo kwenziwa ngeendlela ze-PCR, ezinokumiselwa ukususela ngeveki ye-12 yokukhulelwa. Olu hlalutyo luqhutyelwa kwisigulane kwaye lufuna ukuba kuqeshwe i-gynecologist.
Ukongezelela, esi sifundo sikuvumela ukuba ubone ngokulula ukuba kukho i-Rh-antigen engumntwana, engayifumana ilifa kumpapa, kwaye ufumane uhlobo lwegazi lomntwana, obaluleke kakhulu.
Kuthekani ukuba i-Rh inkalo yowesifazane okhulelweyo kunye nomntwana akafani?
Kuloo meko xa i-Rh ibhinqa yinto engalunganga, ibonakala ngexesha lokukhulelwa. Oogqirha balawula imeko yomntwana.
Ukuthintela ukuphuhliswa kweengxaki, i-antiresus immunoglobulin ifakwe kwangaphakathi kwintombazana, leyo inceda ukususa amaninzi omzimba akhiqizwa kumama njengendlela yokusabela kwimeko yeprotheni enganeni yakhe.
Kwiimeko apho iR Rh ibonakala ingalunganga kumama nomntwana, akukho nto ingqubanayo, ngoko ke,
Ngaloo ndlela, iparameter efana neR Rh ye-fetus imiselwe kuphela ukuba owesifazane okhulelwe unenani elibi. Oku kwenziwa ukwenzela ukuthintela uphuhliso lwe- Rh-conflict, engakhokelela kwimiphumo ebuhlungu, ngokukodwa - ukukhupha isisu. Ukuba oku akukwenzekayo, iphela ixesha lokubambana liyabonwa ngenxa yowesifazane okhulelweyo. Inkqubo ephambili kulo mzekelo kuhlolwa kwegazi apho kuchongwa ukuba ngaba i-antibodies ikhona kumama, kwi-Rhesus yaseRh yentsana yayo encinci, engakazalwa.
