Kuongorora kwe trimester kwakaitwa sei?
Penguva yakatarwa, mukadzi wacho anoongorora zvakakwana. Haisi mu ultrasound chete (kuti uone kuti mwana uye ari kunze kunze kwomwana ari kukura sei), asiwo pakuitisa kuongorora ropa kwamai. Izvi zvinoitwa kuitira kuti zvione kushanduka kunogona kuitika kune maitiro akasiyana-siyana emuchechi asina kunaka (kunyanya, Down syndrome, Edwards syndrome, pamwe nekushungurudzika mukuvandudzirwa kwenheyo yehutano nedzimwe nhengo nemaitiro). Ultrasound, sekutonga, inotarisa ukuru hwepachiviri chemuviri wemukati, kupesana kubva kuchimiro chechiri chiratidzo chezvirwere zvekuzvarwa. Inotarisawo kuti kubuda kweropa kwomwana, kunoshanda sei mwoyo wake, uye kuti muviri wake wakareba kwenguva yakareba sei. Ndicho chikonzero icho chidzidzo chakadaro chinonzi "kuedza kuviri". Izwi remavhiki 11-13 ekudzivirira rinokosha nekuti kana chero kusakanganiswa kuchiratidzwa, amai vakatarisira vachakwanisa kuita chisarudzo pamusoro pokuguma kwehutumbi .
Kugadzirira kwenguva 1 yekuongorora
Chinhu chakakosha zvikuru chekudzidziswa ndicho chisarudzo chekliniki, iyo inofanira kunge yakagadzirwa nemhando dzakanakisisa uye dzakanyanya kunaka. Usati wapfuura nepachirongwa che ultrasound, kakawanda, iwe unongoda kuzadza chirwere (kunwa ½ litre yemvura kweawa asati wagamuchirwa), asi mumakiriniki emazuva ano kubva pakusagadzikana uku kunoderedza masvikiro emagetsi asingadi kuti chidimbu chizere. Mukutaurirana, nokuda kwechirwere chetsika chinonzi ultrasound, chirwere chinofanira kubviswa (maminitsi mashomanana vasati vapinda). Saka kubudirira kuchave kwakakwirira.
Kuti ugovere ropa kubva mumutsipa, unofanirwa kurega kudya kwemaawa masere isati yasvika fence, kunyange zvazvo zvakakosha kuti uzvitore mangwanani, pane chisina chinhu chiri mudumbu. Uyewo, iwe unofanirwa kuomerera kune chikafu chakakosha pakukodzera kwakakwana kwechigumisiro, kureva: kurega mafuta, nyama, chokoti uye hove. Zvokudya zvisati zvaitika kutarisa kwekutanga kwekutatu kwakakosha zvikuru, sezvo zvikanganiso zvose zvingaita zvichabatwa zvisina kufarira mwana.
Kuchengetedza kwechimiro chemagetsi ekutanga kwetatu, mitemo yadzo yakatemwa kunzwisisa zvakanakira chimiro chega chega, inosanganisira kuongororwa kwe:
- HCG (munhu chorionic gonadotropin), iyo inobvumira kuzivisa Down syndrome, kana kuvapo kwamababa - painowedzera, pamwe chete nekumira mumusana wekuberekwa - apo inoderera.
- Puroteni A, yakagadzirwa neparcenta, iyo inofanira kuwedzera zvishoma sezvo fetus inokura.
Zviratidzo zvekuongororwa kwetatu chekutanga (mitemo yeHCG inobva pavhiki apo kuongorora kwaitwa) ndeizvi:
- kubva 25,8 kusvika 181.6 ng / ml pavhiki 10;
- kubva pa17 kusvika ku30.3 ng / ml - pavhiki yegumi neimwe;
- kubva 13,4 kusvika 128,5 ng / ml - pavhiki 12;
- kubva 14.2 kusvika 114.8 ng / ml pavhiki 13.
Kana iwe, kufanana nevanaamai vazhinji, unotarisa kuongorora kwekutanga kwetatu pavhiki 12, mhinduro dze ultrasound dzichave dzakadai:
- coccygeal parietal ukuru - kubva ku 51 kusvika 73 mm;
- Uhu hwenzvimbo yemirasi - kubva pa6 kusvika 2,7 mm;
- bone pfupa - kwete pasi pe3 mm;
- kutara kwemwoyo - kubva pa150 kusvika ku174 kurohwa paminiti.
Genetic screening yekutanga chetatu haifaniri kukurudzira kutya, nokuti izvi ndizvo zvinokubvumira kurega kubata kwekusava nemucheche kana kuti kushandiswa kune pfungwa yokuti ichava yakakosha. Zvisinei, chisarudzo chinobvumirwa nechimwe kana chimwe chinosarudzwa chinotorwa chete nevabereki vakawana kuongorora kwemazuva ose kwekutanga kwemitatu.
