Yokutanga ultrasound pakuberekwa

Iro ultrasound yevakadzi vane pamuviri haisi mukana wekunakisisa wekuona mwana wavo kunyange asati aberekwa, asiwo chimwe chezvinhu zvinonyanya kukosha maitiro ekudzivirira pamuviri. Kunyanya kukosha ndeye ultrasound mumatangiro ekutanga ekudzivirira, sezvo chete mumutatu wekutanga kunokwanisika ku "kuona" kuora mwoyo kwema fetus uye chromosomal zvisiri izvo.

Yokutanga ultrasound pakuberekwa

Gynecologists vanokurudzira kupfuudza zvidzidzo zvitatu zve ultrasound, imwe mumwedzi mitatu yekudzivirira. Zvisinei, pane dzimwe nguva, amai vemazuva ano havakwanisi kuitwa, asi angave maviri ultrasound mumutambo wekutanga wekuita pamuviri: apo yakanyoreswa nevakadzi kubvunzurudza, uyewo yekutanga kugadziriswa ultrasound pakubata (vhiki 10-14).

Ichokwadi kuti ultrasound mumavhiki ekutanga ekudzivirira inobvumira, kutanga, kugadzirisa chokwadi chepamuviri. Izvi zvinonyanya kukosha kana mukadzi asina kukwanisa kubata mwana kwenguva refu. Chechipiri, ultrasound inobatsira kuwana iyo fetal egg, iyo inokosha panguva yekuongororwa kweEctopic pregnancy. Muongorori achaongorora kuve kwehupenyu hwembryo (pamwoyo wake), kusabvisa kana, maziso, kusimbisa kukura kwekudzivirira kwechando.

Mukuwedzera, kushandisa ultrasound pamatambo ekutanga ekudzivirira kunoratidza kuti zvinogona kutyisidzira kubviswa kwepamuviri, pamwe nezvirwere kana kusakanganiswa kwemukati mazita emudzimai wemangwana (uterine myoma, matumire uye mavari cyvari, bicorne uterus, nezvimwewo).

Pakutanga yakarongwa ultrasound pakuberekwa pamasvondo gumi nemasere, chimiro chembryo nemakumbo ayo (chorion, amnion uye yolk sac) inoongororwa, zvinoita kuti chromosomal kusagadzikana (Down's syndrome) kana kusagadzikana (neural tube defects) kunoratidzwa. Muongorori anogadza nguva yekutenda ye fetus, iyo iyo yekucherechedza chiremba-gynecologist inotungamirirwa apo ichisarudza nguva yekubereka mwana.

Kugadzirira kwe ultrasound pakuberekwa

Gadzirira kutsvakurudza, zvichienderana nekushandiswa kwokuti ultrasound inoitwa sei pamuviri. Paunenge uchiita ultrasound mumavhiki ekutanga ekudzivirira, kurovedzwa kwakanyanya hazvidiwi: kuongororwa kunoitwa kuburikidza nevakadzikadzi. Pamberi pekuongororwa, nyanzvi ichakukumbira kuti ubvise chidimbu.

Kana iyo yekutanga inonzi ultrasound inoshandiswa panguva yekuzvitakura mumasvondo gumi nezviviri, ipapo, sekutonga, iyo inoshandiswa kwechirwere chepabonde (kuburikidza nemadziro emimba). Kwemaawa mashomanana usati waitwa, inwa 1.5-2 makapu emusiyo usina carbonated liquid.

Usakanganwa kuunza tauro yakachena kana tambo yekodhi uye kondomu (kana kuongorora kwekare kuchiitwa).

Migumisiro uye zvinowanzoitwa ultrasound pamasvondo gumi nemaviri ekuzvitakura

Iyo nzira ye ultrasound inopedza mavhareji emaminitsi 10-30. Zvadaro chiremba achazadza protocol inokosha, umo achanyora pasi migumisiro yekudzidza zvakadzama.

Ngatitarisei zviratidzo zvakakosha zvekusimudzirwa kwemucheche kwemavhiki gumi nemaviri:

1. Ko cocyx-parietal fetal size (CTE) ine basa rinokosha pakusarudza nguva yekuzvitakura.

2. Kukura kwekorosi nzvimbo . Kazhinji kukosha kwayo hakufaniri kudarika 3 mm. Kuwedzerwa kwechiratidzo ichi kunogona kuratidza chromosomal kusagadzikana kwe fetus. Usavhunduka, pamusana pezvinyorwa zve ultrasound, hapana chiremba achaongorora "Down syndrome". Iwe uchatumirwa kune zvimwe zvidzidzo: test alpha-fetoprotein (AFP) (masvondo 15-20), amniocentesis (kuongorora amniotic fluid) uye cordocentesis (fetal blood sampling from the umbilical cord).

3. Fetal mwoyo rate (HR) . Kazhinji, moyo wemwana unorova pamhanya we 110-180 kurova paminiti pavhiki 12. Kuderedza muhutano hwemwoyo kusvika ku 85-100 kurohwa paminiti. uye kuwedzera kwemapapiro anopfuura 200 bpm. inogona kuratidza hutano hwepamusoro hwekubvisa pamuviri.
