Ultrasound mukana wemukadzi anouya kuti azive kuti zvinhu zvose zvakagadzikana nechechechecheche, anodzika zvakanaka, haanoshai okisijeni, uyewo chero congenital pathologies. Ndicho chikonzero zvibereko zve ultrasound panguva yekuzvitakura zvinonetseka nemukadzi wese ari panzvimbo.
Tsanangudzo yeUSU pamuviri 12 mavhiki
Pamasvondo gumi nemaviri, mukadzi ane pamuviri anotanga kusvika kune ultrasound, kana zvisati zvaitika iye akanga asina matambudziko nekutyisidzika kwekusununguka kwepamuviri uye kusangana kwema fetal egg. Panguva ino, embryo ichiri duku zvikuru, yakareba inenge 4 cm chete, asi kune zviratidzo zve ultrasound panguva yekuzvitakura, izvo zvinoda kuongorora. Chokutanga pane izvi, uku ndiko kukwirira kwekororo nzvimbo (kazhinji kusvika pa2,5 mm) uye kureba kwepfupa remapfu (rinowanikwa ku 4.2 mm). Kusiyana kwehukuru kunogona kuratidzira kukanganisa mukukura kwe fetus uye kunoda kubvunzurudzwa kwe geneticist uye, zvichida, kuongororwa kwakawedzerwa. Mukuwedzera, pane ultrasound pamasvondo gumi nemaviri, inofungidzirwa coccygeal parietal size, inofanira kuenzana kubva kune 42 kusvika ku 59 mm. Inofanira kutakurwa mupfungwa kuti tsika dze ultrasound pakuzvitora dzinoshanduka mazuva ese nekukura kwechecheche, saka pamasvondo gumi nemaviri uye 1 zuva vachave vakasiyana.
Uyewo panguva ino, chiyero chemwoyo chema fetus, chimiro chepentecenta, kureba kwembambo yembilical uye nhamba yemidziyo mairi, kusavapo kwemakwenzi echirwere, pamwe nekubatanidzwa kwepentecenta nezvimwe zviratidzo zvinofungidzirwa. Dzorerai ultrasound ye fetus uye sarudza, kana zvichidiwa, kurapa, chiremba wako anogona.
Dhidhiyo ye ultrasound pakuberekwa pavhiki makumi maviri
Pamasvondo makumi maviri, kuongorora kwechipiri ultrasound kunoitwa, iyo inoongorora zviratidzo zve fetometric. Mwana wacho atokura uye iwe unogona kuenzana kwete chete ye coccyx-parietal ukuru, asiwo urefu hwemukadzi, hupamhi hwebhokisi, biparietal ukuru hwemusoro. Pachine ultrasound, nhengo dzomukati dzomukomana dzinenge dzatooneka zvakajeka - naizvozvo pa ultrasound panguva yekuzvitakura, kuguma kuchava nemashoko pamusoro pemwoyo, maitiro europi, dumbu, mafungiro nemapapu emwana. Kuongororwa kuchaongororazve chiso chechimiro chakanaka chezviso zvepiso, uye maererano nehuwandu husina kuwanda huchaverenga kuenzanisa kwechicheche checheche. Parameters ye ultrasound pakuve nepamuviri inosanganisirawo placenta uye chiyero chekukura kwayo, chiitiko che amniotic fluid. Kamwe zvakare, mutambo wemwoyo uchaongororwa. Migumisiro ye ultrasound ye fetus inobatsira kuongorora kufambisa kwemwana nekushaiwa kwechigarire mukukura nekurema.
Ultrasound masvondo makumi maviri nemaviri ekutenderera - zvinyorwa
Pamasvondo makumi maviri nemaviri, nemucheche asina kuoma, ultrasound inoitwa kwenguva yekupedzisira. Kugadziriswa kwevakadzi vane pamuviri kuchabatanidza zviratidzo zve fetometric (kunze kwekuti coccyx-parietal size, panguva ino haisati yaongororwa), nyanzvi ichadzoka zvakare kuongorora mamiriro ezvinhu ehumukati makuru uye kusavapo kwemaitiro. Mukuwedzera, zvichave zvichibvira kuongorora mharidzo ye fetus uye nzvimbo yekubatanidzwa kwepentecenta.
Mhinduro patafura:
BRGP (BPR) isimba biparietal yemusoro. DB ndiyo urefu hwehudyu. DGPK ndiyo yakakura yebhokisi. Kurema - mu gramu, kureba - mumamita masendimita, BRGP, DB uye DGRK - mumamilimita.
Kana pane zviratidzo, ultrasound panguva yekuzvitakura inogona kuitwa musati wabereka. Zvisinei, semutemo, izvi hazvisati zvichishandiswa, zvinobvira kuongorora hutachiwana hunobatsira neCCTG (cardiotocography).
Kugadziriswa kwemigumisiro ye ultrasound pakuberekwa kunofanira kuitwa nachiremba achifunga nezvezviratidzo zvakasiyana-siyana - mamiriro emadzimai, mhedzisiro yeiyo ultrasound yakapfuura (nguva dzose tora kutaridzika kwema 3 ultrasound pakuzvimba) uye kunyange zvikamu zvebumbiro revabereki vose (somuenzaniso, kana amai nababa vane kukura, mwana inogonawo kukura zvakanyanya kupfuura zvinyorwa zvinorayira). Mukuwedzera, vana vose vakasiyana, uye havagoni kukwanisa zvizere zviyero zvakaenzana. Kana iwe uri mubvunzo pamusoro peimwe zviratidzo, iva nechokwadi chekugovana nachiremba waunovimba naye. Iye achakuudza nezvezvinhu zvekuvandudzwa kwecheche kana kuti achapa kurapa kwakakwana.
