Kodi ndizotheka kugwiritsa ntchito ultrasound?
Madokotala samapereka yankho losavomerezeka. Monga mukudziwira, zonse ziri poizoni ndipo chirichonse ndi mankhwala - ndi mlingo wokha. Amayi ambiri amatiuza kuti atatha kuyamwa, mwanayo amayamba kugwirizana, kuti azichita zambiri, ngati kusonyeza kusakhutira. Panthaŵi ina zinali zochititsa chidwi kunena kuti ultrasound amati imathyola DNA ndipo imasintha kusintha mapangidwe a fetal. Komabe, sayansi imatsutsa mfundoyi. Pakali pano, kuwonongeka kwa ultrasound kwa mayi ndi fetus sikunatsimikizidwe mwachindunji. Koma kukanidwa kwa ultrasound kungabweretse ku zotsatira zoyipa zokhudzana ndi kuchedwa kwa matenda osiyanasiyana a mwana wamwamuna. Amayi, khalani ololera, ngati pali umboni wa kafukufuku, pamene phindu lodziwika bwino likuposa kuvulaza, musachite mantha. Khulupirirani dokotala, osati "nkhani zoopsya" zomwe anzanu amauza. Ndipo ngakhale zipangizo zamakono zimalola kulembedwa kwa ntchito ya m'mimba yochokera m'mimba kuchokera masabata anayi kuchokera pakulera, ndipo magalimoto opitirira masabata asanu ndi atatu, phunziro loyambirira silingakonzedwe kuti lichitike pasanathe milungu khumi ya mimba. Pali ndondomeko inayake, malinga ndi zomwe amayi amtsogolo amatumizidwa ku ultrasound.
Kodi makina a ultrasound amagwira ntchito bwanji? Amatulutsa mafunde amphamvu afupipafupi omwe amatha kuwamva (3.5-5MHz). Mafundewa sagwiritsidwa ntchito mofulumira, ndi ofanana ndi mkokomo wa dolphins (sizowopsa kuti nyamayi ndi chizindikiro cha ultrasound mankhwala). M'madzi, mafunde akupanga amathandiza ma dolphin kudziwa kukula ndi malo a chinthucho. Ndiponso, chizindikiro cha ultrasound chimalola madokotala kulingalira kukula ndi malo a mwana wakhanda. Mtsinje wa US, womwe ukuwonetseredwa ndi matenda a thupi, amatumiza yankho la kuyankha, lomwe limasandulika kukhala fano pazowunikira.
Choyamba ultrasound
Masabata 10-12 - kutsimikiza nthawi yeniyeni yobereka, kuyesa momwe mimba ikuperekera, kuyeza chiwerengero cha mazira ndi kapangidwe ka pulasitiki. Pakali pano, mimba yosakonzekera, poopseza padera, ectopic pregnancy ndi zina zolakwika zingathe kudziwika.
Chachiŵiri ultrasound, masabata 20-24
Kutsimikiza kwa kuchuluka kwa ubwino wa amniotic fluid, mlingo wa chitukuko cha placenta, kufufuza ziwalo za mkati za mwana, kudziwika kwa zovuta zachitukuko (kugonana kwa congenital malformations ya central central system, makamaka hydrocephalus). Pa nthawiyi, mukhoza kudziwa kugonana kwa mwana wosabadwa.
Third ultrasound, masabata 32-34
Kulemberana kwa feteleza kukula kwa nthawi yomwe ali ndi mimba, malo a mwana m'chiberekero, kuyesa magazi kutuluka mu placenta, kuganizira za matenda komanso zofunikira zina zomwe muyenera kuzidziwa kuti mubweretse posachedwa. Kufufuza kwa ultrasound muzinthu zina za mimba, monga lamulo, kumachitika mogwirizana ndi mankhwala a dokotala (pazinthu zapadera kapena kufotokozera deta).
Zitatu-dimensional ultrasound - 3D
Nthawi zina limatchedwa kuti-dimensional ultrasound (gawo lachinai ndi nthawi). Chithunzi chowongolera pa kafukufukuyu chimapangitsa kuti muwone bwino zinyumba zina zomwe zimakhala zovuta kufikako kafukufuku mu njira ziwiri (zachibadwa). Zambirizi ndizothandiza kwambiri kuti zitsimikizire zolakwika zapitukuko zakunja. Ndipo, ndithudi, kufufuza uku kuli kosangalatsa kwa makolo okha. Ngati kawirikawiri awiri-dimensional ultrasound kuyesa mwanayo ndi kovuta kwambiri - mfundo zosamvetsetseka ndi mizere sizipereka chithunzi chonse. Ndi chithunzi chokhala ndi zitatu, mukhoza kuona mwanayo ngati mmene ziliridi. Komabe, ziyenera kukumbukiridwa kuti pakujambula chithunzichi dokotala amalimbikitsira mphamvu ya chizindikiro, choncho musagwiritse ntchito molakwa njirayi. Zinyenyesero za zithunzi m'mimba zidzakhala zoyamba mu album yake ya chithunzi. Ndipo adzatumiza moni yake yoyamba kwa makolo ake - adzakukozani ndi cholembera. Tsopano tikudziwa ngati kuli koopsa kuchita ultrasound mu mimba.
