Yoyamba yotchedwa ultrasound mu mimba

Njira yoyamba yowonjezera ya mayi wapakati si mwayi wapadera wokonzera mwana wake asanabadwe, komanso imodzi mwa njira zofunika kwambiri zowonetsera mimba. Chofunika kwambiri ndi ultrasound kumayambiriro kwa nthawi ya mimba, chifukwa m'zaka zitatu zoyambirira ndizotheka "kuwona" ziphuphu zoopsa za fetus ndi zosawonongeka za chromosomal.

Yoyamba yotchedwa ultrasound mu mimba

Maginecologists amalangiza kuti apitirire mayesero atatu a ultrasound, mmodzi mu trimester iliyonse ya mimba. Komabe, nthawi zina amayi amtsogolo sakhala amodzi, koma osachepera awiri omwe amachititsa kuti mimba ikhale yoyamba: pamene amavomerezedwa ndi amayi, komanso njira yoyamba yomwe imakonzedweratu mu mimba (masabata 10-14).

Mfundo yakuti ultrasound m'masabata oyambirira a mimba imalola, choyamba, kutsimikizira kuti ali ndi mimba. Izi ndizofunikira makamaka ngati mkazi sanathe kukhala ndi pakati kwa nthawi yaitali. Chachiwiri, ultrasound idzakuthandizani kupeza dzira la fetal, lomwe ndi lofunika kwambiri pa nthawi yomwe imapezeka ectopic pregnancy. Katswiri amadziwa kuti mwanayo ali ndi kachilombo ka HIV (pamtima pake), osataya kapena, malasita, kutsimikizira kukula kwa mimba yachisanu.

Kuwonjezera apo, kugwiritsa ntchito ultrasound kumayambiriro kwa mimba kumapangitsa kuti pakhale kuthekera kwa kuthetsa mimba, komanso matenda kapena zolakwika za m'mimba mwa mayi wamtsogolo (uterine myoma, matumbo ndi ovarian cysts, bicorne chiberekero, etc.).

Pa choyamba chokonzekera ultrasound mu mimba pa masabata 10 mpaka 14, mawonekedwe a mluza ndi ma membrane (chorion, amnion ndi yolk sac) amawonekeratu, zotheka kuwonongeka kwapadera (matenda a Down) kapena malformations (neural tube defects) amavumbulutsidwa. Katswiri amalingalira zaka zowonongeka za mwana wamwamuna, kumene kuyang'anitsitsa katswiri wa zamagetsi adzawatsogoleredwe posankha nthawi yobereka.

Kukonzekera ultrasound mu mimba

Konzani kafukufuku, malinga ndi momwe ultrasound imachitikira panthawi ya mimba. Pochita ma ultrasound m'masabata oyambirira a mimba, maphunziro sapadera sali oyenerera: kufufuza kumagwiritsidwa ntchito pogwiritsa ntchito mphamvu yamaginito. Musanayambe kufufuza, katswiri adzakufunsani kuti muchotse chikhodzodzo.

Ngati yoyamba ya ultrasound imagwiritsidwa ntchito pa nthawi ya mimba mu masabata 10 mpaka 14, ndiye kuti, monga lamulo, ndizomwe zimayendera mthupi (kupyolera mu khoma la m'mimba). Kwa maola angapo musanayambe ndondomekoyi, imwani makapu 1.5-2 osakhala ndi carbonated madzi.

Musaiwale kubweretsa thaulo loyera kapena kondomu (ngati kuyesedwa kwina kulikonse).

Zotsatira ndi kawirikawiri ya ultrasound pa masabata 12 a mimba

Njira ya ultrasound imatha pafupifupi 10-30 mphindi. Kenaka dokotala adzalemba pulogalamu yapadera, momwe adzalembera zotsatira za phunzirolo mwatsatanetsatane.

Tiyeni tiyang'ane zizindikiro zofunika kwambiri za chitukuko cha mwanayo kwa nthawi ya masabata 12:

1. Kachilombo ka fetal-parietal fetal (CTE) imathandiza kwambiri pozindikira nthawi yomwe ali ndi mimba.

2. Kukula kwa kolala danga . Kawirikawiri mtengo wake sayenera kupitirira 3 mm. Kuwonjezeka kwa chiwonetserochi kungasonyeze kuti vutoli ndilosawonongeka. Musawopsyezedwe, chifukwa cha deta ya ultrasound, palibe dokotala yemwe angapeze "Down syndrome". Mudzawatumizira maphunziro ena: mayeso a alpha-fetoprotein (AFP) (masabata 15-20), amniocentesis (kufufuza amniotic fluid) ndi cordocentesis (feteleza zitsanzo zamagazi kuchokera ku chingwe cha umbilical).

3. Kuchuluka kwa mtima wa Fetal (HR) . Kawirikawiri, mtima wa mwana umagunda pa liwiro la 110-180 pamphindi pa sabata 12. Kuchepetsa muyeso wa mtima mpaka ku 85-100 kugunda pa mphindi. ndi kuwonjezeka kwaposa 200 bpm. angasonyeze kuti akhoza kuchotsa mimba.
