Ngesikhathi sokukhulelwa, a uchungechunge lwezivivinyo zokubheka ukuthi konke kuhamba kahle yini, kukhishwe ukuthi kukhona ukuguqulwa kwe-chromosomal njenge-Down syndrome noma yikuphi ukungalungi. Noma yikuphi okungahambi kahle okungatholakala ngesikhathi. Lokhu kungadala ukukhathazeka kwabesifazane abakhulelwe, kepha ukwazi ukuthi yiziphi izivivinyo nokuthi zenzani kungakunika ukuthula kwengqondo. Ake sibheke ukuthi yiziphi izivivinyo zokuxilonga ngesikhathi sokukhulelwa.
Ukuhlolwa kokuxilongwa ngesikhathi sokukhulelwa
I-Ultrasound
Isetshenziswa kakhulu ngesikhathi sokukhulelwa, ikakhulukazi i-2D, esetshenziselwa ukuthatha isithombe sengane. Ngenxa yakhe bangakwazi bamba amazinga e-amniotic fluid, inani lama-fetus, ubukhulu bawo, ukuqinisekisa ubudala bokukhulelwa, ukuthi izitho zakhiwa kanjani ...
Futhi namuhla kukhona ama-3D ultrasound lapho ungathola khona isithombe esinobukhulu obuthathu usebenzisa i-ultrasound yendabuko kanye ne-4D lapho ungabona khona umntwana ngobukhulu obungu-3 ngesikhathi sangempela, okungukuthi, ekuhambeni.
La I-Doppler ultrasound iyi-ultrasound enombala osebenzela ukubona ukuthi i- ukugeleza kwegazi kwengane. Ikuvumela ukuthi uhlole izinkinga ngentambo yomzimba kanye negazi lakho nohlelo lobuchopho.
Isiko lomchamo
Kuyinto a ukuhlolwa komchamo ukwazi ukuthi owesifazane okhulelwe unayo yini ukutheleleka komchamo. Ukutheleleka nge-Urinary tract ngesikhathi sokukhulelwa kuvame kakhulu futhi kungenzeka ngaphandle kwezimpawu, ngakho-ke kufanele uqaphele kakhulu uma kungenzeka ngokuba khona kwamagciwane njengoba kungadala umsebenzi ngaphambi kwesikhathi.
I-Amniocentesis
Kuyinto a ukuhlolwa okungenayo ukuthola kungenzeka ukuguqulwa kofuzo futhi sithole izinkinga zempilo. Kuqukethe ukukhipha inani elincane le-amniotic fluid ngenaliti enhle odongeni lwesisu nasesizalweni. I-amniotic fluid iqukethe amaseli avela embungwini kanye namakhemikhali ahlaziyelwa le njongo.
Ukuba wuhlolo olungenayo olufaka izingozi, akwenziwa kubo bonke abesifazane. I-Amniocentesis ingadala ubuhlungu besisu, ukuphuma kwegazi, noma ukulahleka kwe-amniotic fluid, kanti ku-1% wamacala kungadala ukukhulelwa kwesisu. Kunconyiwe uma kunomlando wokungajwayelekile kwe-chromosomal, ngeminyaka noma ngengozi enkulu emiphumeleni.
Isivivinyo sika-O'Sullivan
Yaziwa kangcono njenge ukuhlolwa kweglucose, isetshenziselwa ukukala ushukela wegazi lowesifazane okhulelwe nokwazi ukuthi ngabe sinesifo sikashukela sokukhulelwa. Kuqukethe ukuphuza uketshezi lwe-glucose bese wenza ukuhlolwa kwegazi kabili, eyodwa ngaphambi nangemva kwalokho.
Ucwaningo lwe-Fetal DNA egazini likamama
Kuyinto a ukuhlolwa okungaphambi kokuhlasela kanye nenoveli kokubeletha okwenziwa kusukela ngesonto le-10 lokukhulelwa. Kulesi sifundo unga funda ama-chromosomes ngaphandle kwengozi ngokusebenzisa i- isampula yegazi. Okubi ukuthi ayikwazi ukuthola zonke izifo ze-chromosomal njengoba ezinye izivivinyo zokuxilonga zingenza, kepha ivumela ukutholwa kwe-Down, Patau, i-Edwards syndrome kanye nokukhubazeka kuma-chromosomes ocansi anethuba eliphezulu. Bavumela futhi ukwazi kahle ubulili bengane.
Ukuhlolwa kathathu
Kuyisivivinyo esenziwa ku-trimester yokuqala yokukhulelwa. Siqukethe isivivinyo esihlanganisa ukuhlolwa kwegazi ne-ultrasound, ukuze cacisa cishe amathuba ingane enayo uhlobo oluthile lokungalungi noma ukuguqulwa kwe-chromosomal.
UCordocentesis
Kuyinto a ukuhlolwa okungenayo Kwenziwa kusuka ngesonto lama-20, eliqukethe ukuthola igazi elivela enganeni ngentambo yenkaba. Umsebenzi wawo ukuthola ukukhubazeka kwezakhi zofuzo, ukukhubazeka kombungu, kanye nokungahambisani neqembu legazi likamama. Akusona isivivinyo esivame kakhulu, ngoba sinezinga eliphakeme lokukhipha isisu kune-amniocentesis (2-6%). Kuzoba ngabazali abazonquma ukuthi bazokwenza noma cha, njengazo zonke izivivinyo ezingenayo.
Ukuhlolwa kokuvuthwa kwamaphaphu noma ukuhlolwa kwe-quantusFLM
Kuyindlela yenoveli esetshenziselwa ukukala izinga lokuvuthwa kwamaphaphu kwengane, futhi ngalokho wazi ukuthi ngabe izolungela yini ukuzalwa ngaphambi kosuku oluhleliwe.
I-Chorionic biopsy
Kuqukethe ukuthatha isampula le-placenta ukuthola ukuthi kungenzeka yini izifo zofuzo nokungalungi uma kwenzeka kuba nengozi enkulu yokuba nazo. Kwenziwa phakathi kwamasonto ayi-11-13 okukhulelwa.
Ngoba khumbula ... ukugcina ithrekhi yokukhulelwa kubalulekile ukuze nobabili nilawulwe.
