Pamusana pepamuviri wese, mukadzi anotarisana nematambudziko matatu akarongwa e-ultrasound. Pamasvondo makumi maviri nemasere, yechitatu yakarongwa ultrasound ye fetus. Chinangwa chikuru chekuongororwa ndechekuona kuti zvinogona kunonoka pakukura kwe fetal uye kuongorora kwepentecenta. Sezvakaitwa mumisangano yapfuura - pamasvondo gumi nemakumi maviri nemakumi maviri, chiremba anotarisa mamiriro ekutarisa musoro, mimba, uye ukuru hwemakumbo emufudzi. Itaiwo kuti chiyero che amniotic fluid. Chibereko panguva ino chinotora nzvimbo yekupedzisira muchibereko.
Pakugumisa pamusoro pekutsvakurudza kwakaitwa chiremba anotsanangura, kuti ndeapi nguva yekuzvitora kubata pamuviri kunofananidzwa, ndiko kukosha kwechibereko kunowirirana nezviyero zvepanguva yakati.
Ultrasound pamasvondo 31-32 ekudzivirira inonyanya kuitirwa mukudzidza kwete chete fetus, asiwo iyo placenta. Nyanzvi inosarudza nzvimbo yaro uye rusvingo kune iyo yakaiswa. Idzi ruzivo rwakakosha kuitira kuti uone nzira yekuendesa, uye inonyanya kukosha kana pane zviratidzo zvechikamu chekusiya. Paunenge uchitarisa pasi, chirwere chinotungamirira pamuviri chinogadzirira kugadzirira kwechirwere chekuzvarwa chemukadzi kusvika pakuendeswa.
Kugadziriswa kwe ultrasound pamasvondo 32 ekuzvitakura
Zviratidzo zve ultrasound pamasvondo makumi maviri nemaviri ekuberekwa zvinofananidzwa nematafura anokosha, akabatanidzwa maererano nemitemo yekukura kwe fetus kune imwe nguva yekuzvitakura. Kana zviyero zve ultrasound mumasvondo makumi maviri nemaviri zvakasiyana nemagariro ehupenyu kwevhiki rimwe kana maviri, izvi hazvisi kupotsa. Zvakakosha kuziva kuti chimiro choga choga chiri chega, uye kazhinji zvinogamuchirwa zvinongova magungano. Pamashure makumi matatu nemakumi maviri ekuberekwa kwehuwandu hwezviratidzo hunofanana neizvi:
- BPR - 75-89 mm;
- LZ - 95-113 mm;
- OG - 283-325 mm;
- OZH - 258-314 mm;
- manyowa - 52-62 mm;
- forearm - 45-53 mm;
- femur - 56-66 mm;
- shin - 52-60 mm.
Chiremera chechibereko panguva ino chinenge 1800g, chiyero ichi chinogona kusiyaniswa nemazana maviri magiramu mumativi ose maviri. Kukura komwana kunosvika makumi matatu nembiri masentimita mumavhiki makumi matatu nemaviri, asi izvi zvinorevawo chirevo chepakati uye mwana wako anogona kunge ari shoma shoma kana kuti kwenguva refu.
