Kufunsa ngati kuli koopsa kuchita ultrasound panthawi yoyembekezera, sapereka mpumulo kwa amayi onse amtsogolo. Komabe, ndi zomvetsa chisoni kuti simungathe kupeza yankho losavuta kufunso ili. Madokotala ena amakhulupirira kuti zipangizo zamakono sizimapweteketsa mayi ndi mwana, koma pali ena omwe amanena kuti kusokoneza koteroko sikungathe kupitirira popanda tsatanetsatane, ndipo akunena kuti kuvulaza kumachitika.
Koma ngati mumaganizira za nkhaniyi ndikuyerekezera malingaliro a akatswiri, ndiye kuti tikufika kumapeto kuti ultrasound iyenera kuchitidwa. Popeza kuti zovulaza zomwe zingagwiritsidwe ntchito zimakhala zocheperapo kusiyana ndi vuto lodziwika bwino. Nazi zitsanzo: Panthawi ya ultrasound, n'zotheka kuzindikira kukula kwa mwana wamwamuna (matenda a Down, matenda a mtima, etc.), matenda a intrauterine, chikhalidwe ndi kuchuluka kwa amniotic fluid, chikhalidwe ndi malo a placenta, msinkhu wa ukalamba, kupezeka kapena kupezeka kwa mawu apadera ndi zina zambiri . Makamaka mukawona kuti zambiri mwazifukwazi zingakhudzidwe, kuvulazidwa ndi njira ya ultrasound matenda akuwoneka kochepa. Komabe, wina ayenera kukumbukira lamulo lagolidi kuti zonse ziyenera kukhala zochepa. Kuchita ultrasound tsiku lililonse kuti muonetsetse kuti mwanayo ali bwino, kapena kumuwona, kapena kuyesa kuzindikira za kugonana kwa mwanayo - sizongopeka chabe, komanso ndizovulaza. Choncho funso mwachibadwa limabwera, koma ndi kangati mungapange ultrasound mimba?
Pafupipafupi mungathe kuchita ultrasound, palinso mgwirizano pakati pa madokotala. Koma ambiri a iwo amakhulupirira kuti kupatula pang'ono pakati pa ultrasound matenda a mwanayo ayenera kukhala masabata awiri. Komabe, zonse zimadalira pa mulandu uliwonse. Ndipo ngati zingatheke kuti mayi wina wokhala ndi pakati apange ultrasound kapena ayi, angamuuze mayi ake azimayi okhaokha. Si zachilendo kuti placenta imakalamba msanga, ndipo chikhalidwe chake ndi khalidwe la ntchito zake ziyenera kuyang'aniridwa nthawi zonse. Pachifukwa ichi, ngakhale ultrasound ikhoza kuchitidwa kamodzi pa sabata, ndipo pambuyo pa masabata 40 ngakhale 2-3 pa sabata. Koma ndi zokhazokha zomwe ma ultrasound sadzachita mobwerezabwereza kufufuza ndi kuyesa magawo a fetus, ndipo adzayang'ana pa placenta yekha, ndipo sikudzatenga mphindi zisanu zokha.
Kodi kuchuluka kwa ultrasound kumatenga nthawi zingati?
Pakati pa mimba, kawiri kawiri kafukufuku amafufuzidwa.
Kuwunika koyamba kumachitika pa nthawi ya masabata 11-14. Pa nthawi yomweyo, chiwerengero cha fetus, kupsinjika mtima kumayang'aniridwa, mbali zonse za thupi la mwana zimayesedwa, ndipo kupezeka kwawo kumawunika. Kuonjezera apo, yoyamba ya ultrasound imakonzedweratu chifukwa cha msinkhu wokwanira, ndipo kupezeka kapena kusawopsa kwa kutha kwa mimba kumayesedwa.
Kuwonetsa kachiwiri kumachitika pa nthawi ya masabata 20-24. Kuwonetsetsa uku kumaonedwa kuti ndi kofunikira kwambiri, ndipo pa ndime yake, amayi omwe ali ndi pakati amakhala otchulidwa kwa odwala. Popeza panthawi imeneyi chiwerengero cha ziwalo zonse za mwana zimayesedwa (chiwerengero cha zipinda zomwe zili mu mtima ndi ntchito zake, miyezo ya m'madera a ubongo, chikhalidwe cha impso ndi adrenals, ndi zina zambiri). Panthawi imodzimodziyo, n'zotheka kudziwa matenda omwe alipo kale (matenda omwewo a Down syndrome),
Koma palinso zomwe zimatchedwa kuwonetsera katatu . Iye sali woyenera, ndipo iye amaikidwa yekha ndi dokotala. Amagwira kuyambira masabata 32 mpaka 36. Chithunzichi chimayang'ana chigawo cha placenta, kuchuluka kwake ndi chikhalidwe cha amniotic fluid, chikhalidwe cha umbilical chingwe, chimatenga kulemera kwake kwa mwana, komanso amayang'ana mitu (mutu, wamanyazi, ndi zina zotero)
