Ultrasound - 22 vhiki yekubata

Pakupera kwemavhiki makumi maviri nemaviri, kuongororwa kwekuongorora kunenge kusisati kwaitwa: mukadzi anofanira kuongororwa kare uye inotevera ultrasound inorayirwa pamasvondo makumi matatu nemasere. Uye pamasvondo makumi maviri nemaviri, ultrasound yakaitwa nevakadzi ivavo vane pamuviri vasina kumboongororwa kare kana maererano nezviratidzo. Ichokwadi munguva iyi inogona kutungamira mimwe miedzo ye ultrasound uye kuongororwa munharaunda dzezvokurapa, kana zvisati zvaitika kuberekwa kwemafuro emucheche kwaifungidzirwa. Kuti uite izvi, sarudza chimiro chakakosha kana 3-D ultrasound, uye masvondo makumi maviri nemaviri ekuzvitakura akakodzera kuongororwa, sezvo kubvisa pamuviri kwemishonga kunobvumirwa kusvika masvondo makumi maviri nemana.

22 vhiki yekubata - ultrasound miganhu

Migumisiro ye ultrasound pakutanga kwemavhiki makumi maviri nemaviri ekuberekwa kana kana yatotanga vhiki 22-23 yakasiyana. Izvo zviyero zvakakura, izvo zvinoyera pamasvondo 21-23:

• BDP (biparietal size yehenya) - kubva 51.6 - 54.2 kusvika 54.2 - 57,5 ​​mm;
• DB (kureba kwehudyu) - kubva 35.3 - 38.3 kusvika 67 - 70 mm;
• LTE (ukuru hweparietal yakakura yehenya) - kubva 64 - 67 kusvika 38.3 - 41.3 mm;
• SJ (kureva chidziro chemimba) - kubva 52.5 - 56.4 kusvika 49.4 - 52.6 mm;
• SDHK (kureba kwemafupa emubhokisi) - kubva 46.4 - 49.4 kusvika 56.4 - 59.3 mm.

Iyo inowanikwa pasi pano panguva ino yakafanana uye ine hupamhi hwe 26-28 mm. Nheyo ye amniotic fluid munzvimbo isina mbambo yembilical uye zvikamu zve fetus ndeye 35-70 mm. Mwoyo unonyatsooneka makamuri ose nemagetsi, iyo nzira yemidziyo mikuru yakarurama, moyo wekutengesa uri 120-160 paminiti, rhythm yakarurama.

Chimiro cheuropi chinonyatsooneka, uye upamhi hwemagetsi ekupedzisira huri kupfuura 10 mm. Iwe unogona kuona chiropa, itsvo, dumbu, chikanda uye utumbo we fetus. Mutsara unonyatsojekesa midziyo yose, asi kuvapo kwawo mumutsipa hakutauri chinhu: nzvimbo ye fetus ichiri isina kugadzikana uye inoshingaira inoshandura zvakasununguka muutterine cavity.

22 vhiki yekudzivirira ndiyo nguva apo hutano hwemwana hunoonekwa ne ultrasound , uye zviyero zvevakomana nevasikana zvakasiyana zvishoma nehukuru.
