Muchikamu chechipiri chepamuviri musikana anoramba achifamba (mukadzi wacho anoyera kusvika 15 kushamba kweawa), anotanga kukura uye kukura. Iyo fetus pamasvondo makumi mana anonzwa zvakanaka uye inopindira kune inzwi raamai. Kureba kwema fetus pamasvondo makumi maviri nemakumi maviri nemasere, zviyero zvinokwana 900 g.
Kuberekwa, uko kunowanzoitika, hakunakidzi hupenyu hwemai. Panofanira kunge pasina kuvhara mumakumbo, ukuru hwema fetus pamasvondo makumi mana ndehudiki kuderedza kuputika kubva paitsvo. Asi kana pane zviratidzo, unofanirwa kuenda kumudzimai wegynecologist kuti uongorore, unoitwa kamwechete muvhiki mbiri panguva ino.
Fetus mumavhiki 25-26 ekudzivirira
Pamazuva ano, fetus inofanira kuratidza hukuru hunotevera:
- BDP ( biparietal size yehenya ) - 63.0 - 65.1 mm;
- LTE (ukuru hweparietal yakakura yehenya) - 78 - 83 mm;
- SJ (kureva kureba kwemuviri) - 66.1 - 68.9 mm;
- SDHK (kureva kurema kwebhokisi) - 58.6 - 60.7 mm;
- DB (kureba kwehudyu) - 46.1 - 48.0 mm;
- Uwandu hwepentecenta ndewe 29.3 - 30.0 mm, yakasiyana, pasina mabhii kana krisst.
Fetus mumavhiki 26-27 ekudzivirira (ultrasound-size)
- BDP (biparietal size yehenya) - 65.1 - 69.2 mm;
- LTE (ukuru hweparietal yakakura yehenya) - 83 - 88 mm;
- SJ (kureva kureba kwemuviri) - 68.9 - 71.3 mm;
- SDHK (kureba kwemafupa emubhokisi) - 60.7 - 62.9 mm;
- DB (urefu hwehupi) - 48,0 - 50,9 mm;
- Uwandu hwepa placenta huri 30.6 - 32.6 mm, hunoenderana, husingaverengi kana ma cysts.
Nhamba (koronhe yakakwirira) yeamniotic fluid inofanira kuva mukati ma35 - 70 mm. Mutsara unofanira kuva nemidziyo mitatu. Mumoyo makamuri mana mana uye magetsi ose anonyatsooneka, iyo nzira yemidziyo midziyo (aorta uye mishonga yemapurmita) inofanira kuva yakarurama. Mwoyo unofanirwa kunge uri pakati pe 120-160 neminiti, rhythm yakarurama.
Iko kushambadzira kwe fetus kunofanira kuonekwa zvakajeka pa ultrasound, musoro wepamusoro (zvishoma nezvishoma unobwinya), musoro unofungidzirwa mberi (pasina kuwedzera). Chero kuchinja kupi zvayo muhukuru zvichidzika kunogona kuratidza kubatwa kwekurwadziwa kwechirwere, mune chinangwa chekuwedzera-pane zvimwe zvakanyanya kukura kwema fetus kana kusarudzwa kusina nguva.
