Parizvino, ultrasound, kana imwe nzira, kuongorora, ndiyo nzira yakachengeteka, yakawanda uye inobatsira yekuongorora nguva yekuzvitakura. Transvaginal echography inokubvumira kuti uone mazai emucheche ari muhutachi uterine mazuva makumi maviri mushure mekuberekwa, uye shure kwevana - uye vagari vayo.
Zvakakosha kuti wekutanga panguva yekuzvitakura, ultrasound yakatakura unyanzvi uyo anonyatsoziva mukurapa kwepakutanga asati azvarwa. Ipapo achakwanisa kuve nechokwadi chokuti mwana wacho akanaka, achakwanisa kubatsira vabereki munguva yemberi kutarisa nzeve, maziso uye zviratidzo zvevana remangwana.
Vose vakadzi vane pamuviri vane hanya nezvekuchengetedzwa kwe ultrasound. Muna 1978 (ipapo ultrasound yakanga isinganyanyi kushandiswa), zvidzidzo zvakaitwa kubva kune zvisikwa zvehutano hwechirwere che ultrasound pane zvisikwa zvipenyu. Zvigumisiro zvinoratidza kuti kunyange mumamiriro ekuwedzera akawanda kwehuwandu hwehutano hwe ultrasound, hapana chakakuvadza chinokonzerwa nemambris embrus panguva yekuongorora chirongwa.
Mumaawa matatu ekutanga ekudzivirira, kurambwa kwe ultrasound kunobata zvakaipa. Gore negore, maererano nehuwandu, nezvevana zana muMoscow vanoberekwa neArt syndrome. Haasi vanachiremba vose vanoziva kuti zvinokonzerwa kukanganisa chirwere ichi chakakomba nekubatsirwa kwekunyora mabhii panguva yevhiki 12-13. Zvakakosha kuitisa kuongorora kwekutanga kwechimbichimbi musati wapera nguva ino. Ngationei sei.
- Munguva iyi, zvakanyanya kunaka maitiro e fetus uye zviratidzo zvechromosomal pathology zvakanakisisa zvinowanikwa. Mavhiki mashomanana gare gare, zvikamu zve ultrasound zvinogona kuona Down's syndrome nezvimwe zvirwere zvakakomba zvinogona kuparara pasina tsanangudzo.
- Kana zvichikanganisika nezvechirwere chechiromosomal pathology, vanachiremba vane nguva yekuitisa chidzidzo chekuberekwa kwema genetic uye kana chiitiko chakaipa chinogumisa kusununguka.
- Chetatu yekutanga ndiyo yakakosha yekugadzirwa kwemazuva ekutenda kwema fetus nekururama kwemazuva mashomanana. Kana zviitiko zvipi zvese zvinetso, vadzidzisi vezvipatara vachabatanidzwa zvakajeka panguva ino.
Mumazamu okutanga ekudzivirira, ultrasound inowanikwa mukutsvaga zvinangwa izvi:
- Uchapupu hwekudzivirira. Ultrasound ndiyo nzira yakarurama kwazvo yekuona kubata pamuviri mumavambo ekutanga.
- Tsanangudzo yezwi. Pavhiki yechishanu nekubatsirwa kwe ultrasound, unogona kunyatsoziva nguva yekuzvitakura. Iko kukanganisa kwemazuva maviri chete, nokuti panguva ino zvibereko zvose zvinenge zvakafanana.
- Nzvimbo yeii. Mumatambo ekutanga ekudzivirira, ectopic pamuviri inogona kuonekwa ichishandisa ultrasound. Dzimwe nguva pane zviitiko apo kune nzvimbo ye 2 fetal bags kamwechete. Muchiitiko ichi, imwe inowanikwa zvakarurama, uye imwe iri kunze kwechibereko. Kuti uone kana pane ectopic pamuviri, yekutanga ultrasound inowanzoitwa kakawanda mushure memazuva gumi ekukurumidza.
- Utality ye embryo. Ultrasound muvhiki yechishanu yekuzvitakura inokubvumira kugadzirisa kufamba kwe fetus, uye muvhiki rechina unogona kuona kuti mwoyo we embryo inopfupiswa sei.
- Nhamba yezvibereko. Penguva yemavhiki masere, ultrasound inogona kuona kuvepo kweiviri yolk uye fruity masaga. Nekuvandudzwa kwemashure maviri ekuberekwa, zviitiko zvinowedzera zvakanyanya (zvinenge gumi nguva). Muchiitiko ichi, huwandu hwe ultrasound haugoni kuita, zvinokosha kuti uzviite kakawanda.
- Kunyengetedza kuberekwa. Mune pamuviri, nokuda kwekutanga kwe-ultrasound, unogona kuona kana kutevedza pamuviri kuburikidza ne ovarian cysts, uterine fibroids kana mamwe marudzi emakumbo anoitika.
- Dambudziko rokubvisa pamuviri. Kana mukadzi achiona pazvikamu zvokutanga, zvakakosha kuziva kana mwoyo wemumbryo inoshanda zvakanaka. Pamasvondo 3-4, ultrasound inogona kushandiswa kugadzirisa kana kuputika kwepaccenti hakuitike, uye kana zvakadaro, zvino chengetedza dhigirii rekuchengetedza kuitira kuti kuderedze mikana yekuparara kwemasikana kusvika kudiki.
Munguva yekuzvitakura, yekutanga ultrasound mukutanga kwekutanga kunogona kubatsira kuziva mamiriro ezvinhu eparcenta. Zvose zvinowedzera maitiro ekupa majekiseni zvinopa mukana wekunyatsoronga kuti kutora kunowedzera sei.
