Ukuze kuvikelwe izimo ezinjalo, uhlelo lonke lwezinyathelo ezihloswe ekuvimbeleni i-intrauterine pathologies lakhiwa, okuthiwa yi-diagnostic ngaphambi kokubeletha, noma ngokubeletha. Lolu hlobo locwaningo luyenziwa cishe kuzo zonke izikhungo zokuhlela umndeni kanye nokuhlola kokubeletha.
Iyini ukuxilongwa kwe-perinatal futhi kungani kuyadingeka?
Uma sicabangela lolu hlobo locwaningo ngokuningiliziwe futhi sikhulume ngokuthi yiyini umgomo oyinhloko wokuxilongwa kwesifo socansi, ngakho-ke, lokhu kuyisifo sokutholwa kwezingane ezisemuva, ngisho nasesiteji sokubelethwa kwesisu. Le ndawo yokwelapha ibhekene ikakhulukazi nokusungulwa kwe-chromosomal, izifo ezifa kanye nezinkinga zokuzalwa ezinganeni esikhathini esizayo.
Ngakho-ke, odokotela namuhla banethuba lokuthola amathuba okuba nengane enezinto ezingavamile ze-chromosomal kakade zingakapheli i-trimester yokukhulelwa ngezinga eliphakeme lokunemba (cishe ngo-90%). Ukunaka okukhethekile kubhalwa izifo ezinjengama-Down syndrome, i-Edwards syndrome, i-Patau syndrome (i-trisomy yama-21, i-18 nama-chromosomes angu-13, ngokulandelana).
Ngaphezu kwalokho, njengengxenye yezinkinga zokuhlolwa kwe-diagnosis ye-perinatal, i-ultrasound ingakwazi ukuhlola izifo ezifana nesifo senhliziyo, ukuphazanyiswa kobuchopho nomgogodla, izinso ze-fetus, njll.
Ziziphi izindlela ezimbili ezisetshenziselwa ukuxilongwa nge-perinatal?
Njengoba esitshele ukuthi lokhu kuhlolwe yi-perinatal, futhi ngalokho okwenziwayo, sizocubungula izinhlobo eziyinhloko zocwaningo ngazo.
Okokuqala, kubalulekile ukusho ngokuhlola izivivinyo, cishe cishe wonke owesifazane ozwa ngesikhathi sokubeletha kwengane yakhe. Isifundo sokuqala esinjalo senziwa ngesikhathi samaviki angu-12, futhi kuthiwa "ukuhlolwa kabili". Esigabeni sokuqala, owesifazane uhamba nge-ultrasound kudivayisi ekhethekile, ehluke kakhulu kulokho esetshenziswa ngokuvamile ezitho zangaphakathi. Uma kwenziwa, ukunakwa okukhethekile kubhalwa kumanani wemingcele enjalo njengokwesayizi we-coccygeal-parietal (CTE), ubukhulu bekhala lekolishi.
Futhi, ukubala ubukhulu besithambo samasalane esiswini, akubandakanyi ukukhubazeka okukhulu okuthuthukiswayo.
Isigaba sesibili ekuqhubeni izifundo zokuhlola, kuhilela ukutadisha igazi lomama ozayo. Ukuze wenze lokhu, i-biomaterial isuswa futhi ihanjiswe emtholampilo, lapho kuhlaziywa khona izinga lamahomoni okwenziwa ngokuqondile yi-placenta. Lawa amaprotheni amabili ahlobene nokukhulelwa: i-RAPP-A ne-subunit yamahhala ye-griadotropin ye-chorionic (hCG). Nge-chromosomal engavamile, okuqukethwe kwala maprotheni egazini ngokuphambene kuncike ekujwayelekile.
Idatha etholakala ngenxa yezifundo ezinjalo ifakwe ohlelweni olukhethekile lwekhompyutha olubala ngokunembile ingozi yokuthuthukisa i-chromosomal pathology esikhathini esizayo. Ngenxa yalokho, isistimu ngokwayo inquma ukuthi owesifazane usengozini noma cha.
Zonke lezi zinto zenziwa ngaphansi kokulawulwa okuqinile kwe-ultrasound ukuze zingalimazi umntwana, futhi kuphela ochwepheshe abaqeqeshiwe kakhulu. Amaseli e-fetal avela athunyelwa kwisifundo se-karyotype, emva kwalokho umama unikezwa impendulo eqondile - kungakhathaliseki ukuthi umntwana unempilo engavamile noma cha. Ukutadisha okunjalo, njengombuso, kwenziwa ngokuhlolwa kokuhlola okuhle.
Ngakho-ke, wonke owesifazane kufanele azi ukuthi kungani ukuxilongwa okusebenzayo kwenziwa esikhungweni sokubeletha, futhi uqonde ukubaluleka kwalezi zifundo.
