Iviki lamashumi amabili liyisikhathi esikhethekile, esibalulekile sokukhulelwa. Kuleli sonto, abesifazane abaningi abakhulu kakhulu bazizwa ukuhamba komntwana kuqala. Kuye kwadlula ingxenye eyodwa yokukhulelwa: ngemuva kwe-toxicosis, isigaba esiyingozi kakhulu sokuthuthukiswa kwe-fetus, i-US yokuqala. Ngeviki lama-20, umama ozayo angabelwa ukuhlolwa kokubili kwe-ultrasound ngesikhathi sokukhulelwa . Ukugxila okukhethekile kubhalwa ku-fetometry (imingcele eyisisekelo) ye-fetus emavikini angu-20, ngoba ubukhulu bomntwana obuvumela umuntu ukuba anqume ukuphutha ekuthuthukisweni kwawo.
Imingcele ye-fetal ngesonto 20
Ngokungafani ne-ultrasound yokuqala emavikini angu-10-12, i-ultrasound ye-fetus yamaviki angu-20 ifundisa kakhulu: hhayi kuphela izinga lokushaya kwenhliziyo ne-coccyx-parietal usayizi (KTP) wengane kubhaliwe, kodwa futhi isisindo, ubukhulu bekhanda biparietal, ikhanda nesisu sesisu , ububanzi besifuba, kanye nobude bethanga, umlenze ongezantsi, i-forearm kanye nehlombe.
Kungani sidinga izilinganiso ezinjalo ngokucophelela? Ubukhulu be-fetus emavikini angu-20 wokukhulelwa kusiza isazi sezifo-mzimba ukuba sithole iziphetho mayelana nesilinganiso sokukhula nentuthuko yengane, ukukhomba ukuthi kungenzeka yini ukuthi i-pathologies ibe khona nokuthi ithathe izinyathelo ezidingekayo ngesikhathi.
Kodwa-ke, ukwehlukana okuncane ekukhuleni nasekutheni isisindo somntwana emasontweni angama-20 akufanele sibe isizathu sokwesaba. Sonke sasihlukile: sincane futhi sinondlekile, sinemilenze ende noma emifushane kanye nezingalo, nxazonke noma ikhanda elide. Zonke umehluko zibekiwe ezingeni lezakhi zofuzo, ngakho akumangazi ukuthi izithelo ziyahlukahluka komunye nomunye. Ngaphezu kwalokho, ukuthuthukiswa kwe-intrauterine kuvame ukuvela ngokuphindaphindiwe, futhi ezimweni eziningi izingane zithola amazinga. Kungase kube nempumelelo ekusunguleni isikhathi sokubeletha sokuya esikhathini sokugcina.
Enye into lapho ukuphambuka kusuka kwendabuko kudlula izinkomba ezimbili zeviki. Isibonelo, i-fetus yamaviki angu-20-21 emiphakathini eyisisekelo ihluke kancane kusuka kumntwana amasonto angu-17-18. Kulokhu, ukuphuza ukuthuthukiswa komntwana kungenzeka ngempela, okusho ukuthi ukuhlolwa nokwelashwa okwengeziwe kuyodingeka.
I-Fetometry ye-fetus ingamaviki angu-20 - okujwayelekile
Yimiphi imingcele ye-fetus ngesonto 20? I-KTP (noma ukukhula komntwana) emavikini angu-20 ngokuvamile kuvamile 24-25 cm, nesisindo - 283-285 g. I-BDP emavikini angu-20 ingahluka phakathi kuka 43-53 mm. Umjikelezo wekhanda uzoba ngu-154-186 mm, futhi isisu esiswini - 124-164 mm. Ububanzi besifuba kufanele kube okungenani u-46-48 mm.
Ubude bezitho zomntwana obusweni buhloswe ngobukhulu bamathambo we-tubular:
- i-femur - 29-37 mm;
- i-humerus - 26-34 mm;
- isifuba - 22-29 mm;
- amathambo omlenze ophansi - 26-34 mm.
Isonto lama-20 lokukhulelwa - ukuthuthukiswa komntwana
Ngokuvamile, ngeviki lama-20 zonke izitho zomntwana zenziwe ngokugcwele, ukukhula nokuthuthukiswa kwazo kuyaqhubeka.
Emasontweni angama-20, ekugcineni ingane ivule amehlo akhe, futhi ingabonakalisa ukukhanya. Ngalesi sikhathi, isithelo siphuza ngokucophelela iminwe futhi sizwa ngokugcwele. Kusukela evikini lama-20 lokukhulelwa, odokotela batusa ukuqala ukuxhumana nengane. Ingane ihamba ngokufudumele, kanti abanye omama sebevele beyazi isimo sezempilo kanye nokuthandwayo kwenzalo yabo ngokulingana nokunyakaza kwe - fetal ngesonto 20 .
