Nyanzvi dzekuongorora vana vasati vasvika dzinodana kusangana pamwe nekuongororwa, mitemo yakawanda panguva imwechete iyo inobvumira kuzivisa kuberekwa kusina kunaka mumucheche (Down syndrome, Edwards syndrome, neural tube defect) uye kudzidza chimiro chemuviri wake nematunhu akakomberedzwa. Ichokwadi, iyo yakanyatsojeka zviyero izvi, iyo yakawedzerwa kuvimbika. Saka, pakutsvakurudza kwakadaro, unofanirwa kutendeukira kuvadzidzi chaivo kuti vabatsirwe. Ndechipi "chibereko" ichi, kuongorora, uyewo kuti inoshandiswa sei iwe uchadzidza munyaya yechinyorwa chinoti "Kuongorora kwepabonde, mhinduro yekuedza".
Maererano nekurudziro kweWorld Health Organization, zviratidzo zvekuongorora kwakadaro kungave zvikonzero zvinoverengeka:
- zvirwere zvenhaka mumhuri pfupi;
- kunyanya kubvisa pamuviri zvinokonzerwa nemitemo yekutanga;
- vakatamisa bhakitiriya, zvirwere zvehutachiona (semuenzaniso, hepatitis, rubella, herpes, cytomegalovirus);
- Zera remukadzi rinotevera makore 35-39;
- kusvibiswa kwezuva kana zvimwe zvinokuvadza kune mumwe wevakaroorana vasati vaberekwa.
Asi, kwete nhungamiro kune yekuongorora uye ultrasound, kana kunyange nemigumisiro yavo inotevera, zvinoreva kuti chirwere chinenge chichizoitika. Somuenzaniso, maererano nezera, nhamba dzinoti zvinopesana. Kungofananidzwa chete nemufananidzo wakaisvonaka wekuzvitakura, mukana wechinetso unowedzera zvishoma. Saka chengetedza hurongwa hwako hwemitsipa uye uchinje kusvika pakuberekwa kwemwana ane utano hwakakwana.
Chii chinobatanidzwa muchidzidzo?
Yakarongedzwa kwevhiki 10-13 yekutakura. Mukuenzanisa nedzidzo dzakafanana mumutsara wechipiri, dzinofungidzirwa kuti dzakarurama, uye zvishoma nezvishoma muzana wezvakaipa. Nekubatsirwa kwepurogiramu yekombiyuta inokosha inokubvumira kuti uverenge panjodzi yekubatana kwechromosomal kusagadzikana kwekukura kwekuberekwa, maererano nemigumisiro yeropa rekuongorora ropa remukadzi uye ultrasound, nyanzvi dzinoongorora mamiriro ediki. Zvose zvinotora zvinotora 2-2.5 maawa. Munguva ye ultrasound, chiremba achagadzirisa ndokupinda mubvunzo remibvunzo yehupamhi hwechikanda kubva ku coccyx kusvika korona (CTE), kubwinya kwekorosi nzvimbo - cervical fold, nzvimbo yekuunganidza ye subcutaneous fluid (TBP). Izvi zvinongobvumidza kutsvaga sezvakanyatsoita izwi rekubata pamuviri, kutora mimba yakawanda uye rudzi rwayo, iyo inonyanya kukosha pakucherechedza kwakanaka kwekuzvimba kwakadaro, pamwe chete nezviratidzo zvisingaoneki zvekukanganisa kunogona kuwedzerwa kwekuberekwa. Dhawuni yose inopinda mubvunzo remibvunzo uye inofungidzirwa mune zvekuwedzera kuongororwa. Kuva nemigumisiro ye ultrasound, unogona kupa ropa. Biochemical laboratories analysis inoitwa nevanyanzvi kuitira kuti tifunge nezvezvinotevera:
- kusununguka beta subunit yevanhu chorionic gonadotropin (beta-hCG). Ichi chikwata chakasiyana chinogadzirisa zviratidzo zvehupenyu uye hutachiona hweHCG - huwandu hwekuzvitakura hormone inobereka masero echerion (embryo shell).
- zvakananga whey protein A (PA-PP-A), inobatanidza mukuumbwa kwezvidziviriro zvekudzivirirwa kwezvirwere zvechirwere chemuviri, uye kukura kweparcenta. Kuti agadzirise migumisiro yeropa rekuongorora uye ultrasound, chiremba anodawo ruzivo rwakakwana pamusoro pemukadzi.
Kurema kwemuviri, zvinodhaka zvakatorwa, zvisinei kana achiputa asati abata pamuviri - izvi zvose nedzimwe nhepfenyuro zvinotariswa pakuongorora mutsara wekutanga. Zvine ruzivo rwakanyatsorondedzera nezvehupenyu hweamai nevana, geneticist ichapa mazano. Iye zvino tava kuziva kuti kutarisa kwepabonde ndeipi, migumisiro yekuongorora inoratidza zvinhu zvose zvakanyatsokwana.
