Yechipiri yakagadzirirwa ultrasound pakuberekwa inoitwa mavhiki makumi maviri nemaviri ekuberekwa. Chibereko chezera iri hachigoni kuonekwa zvachose, saka chiremba anotarisa kumativi ose emuviri uye nhengo dzomwana. Mufananidzo uyu usina kukwana haugadziri muongorori ane ruzivo kuti asaona kusakanganiswa mucheche kana kukurudzirwa kwake, pamwe nekugadzirisa hutano hwomwana.
Ultrasound mumutambo wechipiri wekuita pamuviri ichasarudza kukura kwe fetus, nekudzivirira matambudziko akasiyana-siyana ekudzivirira. Chiremba akanyatsodzidza zvose mwana wacho pachavo uye mamiriro ehutachi, saka kutaura nzvimbo yemukomana. Nzvimbo yefruiting inosanganisira: amniotic fluid, placenta, umbilical cord.
Fetal ultrasound pavhiki 21
Kutsvakurudza kwemashoko panguva ye ultrasound pamasvondo makumi maviri nemakumi maviri nemakumi maviri nemashanu kunopa mukana wakanaka kwazvo wekuita nechokwadi chokuti vabereki vari kukura zvakanaka. Icho chiri mumutambo wechipiri wepamuviri iyo yese nhengo dzomukati dzomwana dzinoonekwa pa ultrasound kuongororwa. Chiremba anoongorora mamiriro emwoyo, mudumbu nedzimwe nhengo kuti asiye kuvepo kwehutano. Pamusoro peizvi zvinotarisirwa mberi nekufambiswa kwekuzvitakura nekuzozvarwa munguva yemberi kune vakadzi. Mwoyo unorohwa nemwana uyu 120-140 kurohwa paminiti, iyo inenge kaviri kushaya mwoyo kwevanhu vakuru. Chiremba anoteerera achaverenga zvose zvigunwe pamaoko nemakumbo emwana wako, nokuti mubvunzo uyu unotambudza amai vose, kunyanya kudarika uremu hwemwana.
Ultrasound inogona kusarudza kuti inoshanda sei fetus. Zvisinei, panguva ye ultrasound, mwana anogona kunge ari muhope kana kurara, saka pfungwa iyi haibhadhari.
Maitiro e ultrasound pamasvondo makumi maviri ekuberekwa
Uziste anoita kuongorora kwakanyatsonaka kwe fetus, kuenzanisa rutivi rwemusoro uye mimba, pamwe nehukuru hwehwamapfupa, uye nechemberi-nguva yechebe.
Kuyera kwema fetus kwemavhiki makumi maviri nemasere ekuberekwa:
- pamavhiki makumi matanhatu ekurema kwemucheche ari mudumbu reamai vanosvika 300-350 g, uye kukwirira kwayo ndeye 18-25 cm;
- musoro circumference kubva pa166-200 mm;
- ukuru hwema frontal-occipital 60-72 mm;
- rutivi rwemuviri we fetus ndewe 137 -180 mm;
- kureba kwegumbo kubva pamabvi kusvika pachidya (femur) 32-40 mm;
- kureba kubva patsoka kusvika kumabvi (mashoma emapfupa) 29-37 mm;
- kureba kwemaoko kubva pamafudzi kusvika kuneheta (humerus) 29-37 mm;
- kureba kworuoko kubva pachiuno kusvika kuhokwe (forearm mafupa) 24-32 mm.
Nemhaka yezviratidzo izvi, chiremba anosimbisa nguva yekuzvitakura. Iko kukanganisa munguva yekushandiswa kwe ultrasound pamasvondo makumi maviri nemasere ekuberekwa kunogona kusvika kune mazuva manomwe.
Madzimai haafaniri kutya nguva pfupi, nekuti mwana mumwe nomumwe ane ruzivo rwehutano hwake, uremu uye chiyero chevana vezera rimwe rekuberekwa zvinogona, kunyange zvishoma, zvakasiyana kubva kune mumwe.
Ultrasound ye fetus nemukati
Iyo amniotic fluid inodzivirira mwana kubva pamakumbo. Uyewo, vanobvumira kusagadziriswa kusvibiswa kumwana zvinovaka muviri uye oksijeni kuburikidza nemutsara wembilical. Kuongorora amniotic fluid munguva ye ultrasound kunogona kuratidzawo chirwere kana kusavapo. MuAmniotic fluid, huwandu hwavo uye hutano zvakadzidzwa. Mukuvapo kwezvakatsauka kubva pamitemo ye ultrasound, chiremba achapa imwe nyanzvi yekuongorora uye kurapwa.
Kudzidza kwepalacenta kunowanikwa mumativi maviri - nzvimbo uye chimiro. Nzvimbo ye placenta yakasiyana:
- Pamberi, kana yakabatanidzwa kumadziro anterior emuviri;
- Shure, zvichienderana, kana ichibatanidzwa kumushure wemashure;
- uye previa, iyo inonzi inonyanya kuipa.
Panguva yekutaura kwepentecenta inoputira chibereko chechirwere. Muchiitiko ichi, mukadzi wacho anokurudzirwa kuti aende zvishoma sezvinobvira, uye kubvisa zvose zvigadziriswa kuitira kuti ave nepamuviri. Apo bonde rinowedzera, kune mikana yakawanda yehutachiona hwemukati, izvo zvinoda kunyatsodzidza mukadzi akazvitakura.
Munguva ye ultrasound pamasvondo makumi maviri nemasere ekuberekwa, chiremba anoongororawo mutsara unobatanidza amai nemucheche. Muchikamu chechipiri chekuita pamuviri, mwana anogona kuvharwa mumutsara wembilical. Izvi hazvirevi nezvehutachiona. Nemhaka yekukwirira kwemucheche, inogona zvakare kukurumidza kushandurwa, sezvo yakabatanidzwa.
Muchibereko chechivharo chinofanira kunge chakanyatsovharwa munguva yose yekuzvitakura. Basa re ultrasound nderokuona kana kune kuchinja kune ngozi kune iyo. Kana chirwere chechivharo chiine chinyararire chiduku cheperiyx yechipfuva, kune mikana yakakura yekuberekwa kusati kwaitika. Chiremba uyo akatungamirira ultrasound achangotumira mukadzi kuna chiremba.
Chechipiri inonzi ultrasound panguva yekudzivirira inobvumira mukadzi ane pamuviri kudzivisa zvinetso zvisina kufanira, uyewo kubvisa kusava nechokwadi kwakawanda pamusoro pehutano hwakanaka
