Kuberekwa kwepabonde

Kuongorora kwepabonde nderimwe yenzira dzinonyanya kukosha yekuongorora vakadzi vane pamuviri, vachibvumira kuti vaone kukanganisa kwakanyanya kwema fetus, kana zviratidzo zvisingaoneki zvezvakaipa zvakadaro. Inofungidzirwa seimwe yenzira dzakanyanya nyore, dzakachengeteka uye dzinodzidzisa dzevana vanotarisira. Kuchengeta kunoreva kune avo vanoongorora vanoitwa zvakanyanya, kureva, kune vose vakadzi vane pamuviri vasingasaruri.

Tsvakurudzo inosanganisira zvinhu zviviri:

1. Kusarudzwa kwepachirwere chekuberekwa kwepanyama - kuongororwa kwechiropa chinokonzera amai kuti vaone zvimwe zvinhu zvinoratidza humwe hutachiona.
2. Ultrasonic kuongororwa kwe fetus.

Kuongorora kusati kwapera kwetrisomy ndeimwe yezvidzidzo zvinokosha zvikuru izvo hazvisi izvo zvinotenderwa, asi zvinokurudzirwa kuti kana amai vane ramangwana vane makore anopfuura makumi matatu, kana vana vane maitiro ekusaremara vakaberekerwa mumhuri, uye kana pane mutoro. Kuongorora uku kunobatsira kuziva mungozi, kureva kuti, chaizvoizvo, mukana wekuberekwa kwecheche ane Edwards chirwere (trisomy 18 chromosomes - dzakawanda dzisina kukanganisa kwemukati uye nhengo dzomukati, kukanganisa kwepfungwa), Down's disease (trisomy 21 chromosomes) kana neural tube defect (kureva, kuparadzanisa spine), Patau syndrome (trisomy 13 chromosomes - zviremera zvakanyanya zvenhengo dzomukati nechekunze, idiocy).

Kuongorora kwepabonde kwe1 trimester

Muchikamu chekutanga chekutanga, kuongororwa kunoitwa panguva yekutenda kwemavhiki gumi nemasere uye inobvumira kutsanangura kana kukura kwe fetus kunofananidzwa nenguva, ingave kune mimba yakawanda, ingave mwana ari kukura kazhinji. Panguva ino, trisomy 13, 18 uye 21 dzinosarudzwa.Achiremba anonzi ultrasound anofanira kuyera iyo inonzi inonzi collar nzvimbo (iyo nzvimbo iyo mvura inosvika mumutsipa pakati pezvinyoro zvinyoro uye ganda) kuve nechokwadi kuti hapana chakaipa mukukura kwomwana. Migumisiro ye ultrasound inofananidzwa nemigumisiro yechirwere chemudzimai wehutachiona (iyo yehutachiona hwemimba uye RAPP-A inowanikwa). Kuenzanisa kwakadaro kunoshandiswa uchishandisa purogiramu yemakombiyuta inofunga nezvemunhu mumwechete wemukadzi ane pamuviri.

Kuongorora kwepabonde kwechipiri chetatu

Muchikamu chechipiri (pamasvondo 16-20), kuongororwa ropa kunowanikwawo kune AFP, hCG uye isina estriol, uye ultrasound ye fetus inoitwa uye ngozi ye trisomy 18 ne21 inoongororwa.Kana pane chikonzero chekutenda kuti chimwe chinhu chakashata nemucheche, ipapo nhungamiro inopiwa kuvhuna kuongororwa kunobatanidza nekuputika kwechibereko uye kuunganidza amniotic fluid uye fetal blood, asi mu 1-2% yezviitiko saizvozvo nzira dzakadaro dzinokonzerwa nekudzivirira pamuviri uye kunyange rufu rwomwana.

Muchikamu chechitatu, pamasvondo 32-34, ultrasound inoshandiswa kuitira chinangwa chekucherechedza nguva dzakatadza kuonekwa.
