Kuchengetedza kwechipiri chetatu

Ichokwadi kuti, amai vose vekupedzisira vanoda kudavira kuti mwana wavo achazvarwa akaine utano. Asi, sezvakaratidzwa zvinoratidza, zvirwere zvakasiyana-siyana zvemu fetus hazvishamisi.

Zvirwere zvakadai seArt's syndrome, Edwards, nezvimwe zvakawanda zvinokonzera chromosomal zvakangwara zvakakwana:

• Chokutanga, hazvigoneki kufanotaura kufambira mberi kwavo (semutemo, chirwere chinoumbwa pakarepo mushure mekuberekwa, uye vabereki kana vanachiremba vanogona kukanganisa izvi);
• Chechipiri, zvirwere izvi zvakaoma kuyananisa noupenyu hwakakwana, hazvibvumi nemishonga kana kurapwa, uye vana vakaberekwa vanogona kunzi vachatongerwa kutambura;
• chechitatu, zvakaoma zvikuru kuziva chirwere ichi mu utero. Kunyange ichangobva kuongororwa nzira dzisingatombogone kuita chirevo chekupedzisira. Muzviitiko zvizhinji, chete kuwandisa kwehutano hwemwana ane anomalies kunoziviswa kuvabereki. Uye chisarudzo chekuchengeta mimba kana kwete, chinoramba chiri kwavari.

Mazuva ano, vanachiremba vanokurudzira kuti vakadzi vose vane pamuviri vanotarisana nekuongorora mawere mukutanga uye kwechipiri chetatu yekuzvitora kuitira kuti vaone njodzi yekuva nemwana ane zvirwere zvakanyanya kukura. Iyi kuongororwa inoonekwa seyo yakatendeseka.

Chii chinorehwa nekuongorora purogiramu yechipiri chetatu?

Munguva yose yehutachiwana, vanaamai vakangwara vanouya mune mbiri yekuongorora vasati vazvarwa; Zvisinei, kuongorora kwechipiri kunowedzera ruzivo, nokuti panguva yakadaro zvakajeka zvikuru kunzwisisa zvinokanganisa kubva kune zvakasarudzwa mumatsananguro zvinogona kureva, uye mamwe mararamiro anenge atooneka zvakajeka pane ultrasound.

Pakati pese, kuongorora kwepininatal kwechipiri chetatu kunoreva:

1. Kuchengetedza kwechimiro chechimiro chechipiri chetatu (kuongorora katatu), izvo zvisingaratidzi chinhu kunze kwekuteerera mitemo yehutano hwezvinhu zvitatu muropa raamai (AFP, hCG, estriol).
2. Kuongorora ultrasound kunodzidza kwakadzika (chimiro chemuviri wechechi fetal rinonyatsoongororwa, mamiriro epa placenta uye amniotic fluid yakatemwa).
3. Cordocentesis imwe yedzidzo yakaitwa maererano nezviratidzo zvechiremba.

Zviratidzo uye mitemo yekuongorora kwechipiri kwekuita pamuviri

Saka, mukugadzirisa kuongorora, danho re AFP rinotsanangurwa. AFP iprotini inobudiswa ne fetus. Kazhinji AFP inogona kuchinja mukati me15-95 U / ml, zvichienderana nemavhiki mashoma kuongorora kwechipiri kwakaitwa. Kana zvakaguma zvawanikwa zvaive zvakakwirira kudarika zvinowanzoitika, vanachiremba vangaratidza kutyora kwekugadzirwa kwemutsipa wepelinha kana kusakwana kweeural tube. Kusadudzwa kwe AFP kunogona kuratidza zvirwere zvakawanda, zvakadai seA Down's syndrome , Edwards syndrome, kana kuti Meckel syndrome. Zvisinei, mumamiriro ezvinhu akadaro, kududzirwa kwekuongororwa kunoshamisa.

Chinhu chechipiri icho vanachiremba vanoona mushure mekuongorora kwechipiri ndeyezinga reestriol. Kukosha kwayo kunofanira kuwedzera pamwe nekuwedzera kwezera remakore. Uwandu hwemaestriol hunogona kuratidza chromosomal kusagadzikana (Down syndrome) kana kutyisidzirwa kwekuberekwa kusati kwaitika.

Uyewo, chromosomal pathology inoratidzwa nehupamhi hwepamusoro hCG .

Nekuongorora screen ultrasound, saka iwe unofanirwa kuvimba chete nehutano uye kutarisira chiremba anoita nzira yacho.

Kuongorora kwechipiri kuini?

Zvichienderana nemaawa mashoma kuongorora kwechipiri kwakaitwa, kururamiswa kunotangwa pakunotsanangurira migumisiro. Chaizvoizvo, nyanzvi dzinokurudzira kuti tisanonoka neongororo uye tive nenguva yekuendesa miedzo inofanirwa kutanga kwevhiki re20. Nguva yakakodzera yekuongorora kwechipiri kwekuita pamuviri masvondo 16-18.
