Intshisekelo eyenza ukuthuthukiswa kwengane ngaphakathi kwesibeletho akushiyi umama kusukela ekuqaleni kwenqubo yokubeletha. Kodwa-ke, idatha etholakala ngenxa yezifundo ezihlukahlukene ayisoloko icacile, futhi ukubonisana kwezikhungo zombuso wezinkinga zokubeletha nakho akufani ngokuningiliziwe nokulula. Sizozama ukuchaza ngokuningiliziwe futhi kufinyeleleke izinkomba eziyinhloko zokukhula nentuthuko ye-fetus yamaviki.
Ishadi lesayizi le-Fetal ngesonto
Ukuze kwenziwe umsebenzi wezidakamizwa kanye namazinyo wokubeletha, itafula elikhethekile ladalwa, eliqukethe izinkomba eziphezulu zokukhula kwengane kusukela ekuqaleni kokubeletha kuya kwezidingo. Siyabonga ukuthi kungenzeka ukuhlanganisa izilinganiso zobukhulu be-fetus ngamasonto ngenqubo yokukhulelwa, isimo jikelele somama nengane, ukuthola isithombe esinembile sokuthuthukiswa kwengane, njalonjalo. Ukutholakala kwalolu lwazi kunika omama ithuba lokuzibonela ngobuqiniso ngemiphumela ye-ultrasound noma ezinye izindlela zokucwaninga.
Yiziphi ubukhulu be-fetus yamasonto?
Mane ufuna ukuphawula ukuthi ulwazi olungezansi aluyona into ejwayelekile, futhi akudingeki ukwethuke uma "usayizi" wengane yakho encane noma encane. Ukukhulelwa ngalunye kuyindlela eyingqayizivele futhi eyingqayizivele yokuzalwa kokuphila okusha, okungeke kube okufanayo. Ngakho-ke, yiziphi ubukhulu be-fetus ngezigaba ezahlukene zokuvuthwa:
- Ubukhulu bombungu, obuneminyaka engama-4 ubudala, bufinyelela cishe ngo-4 mm kanti, cishe, owesifazane usevele ekwazi ngokukhona kwayo.
- Sekuneminyaka engama-8 ubudala, umbungu ungase "uziqhayise" ngokukhula kwamamitha angu-3, futhi ekuqapha amadivaysi e-ultrasound, ukubhekwa kobuso besikhathi esizayo kubhekwa.
- Ubungako be-fetus emavikini angu-12 buhlukahluka kusukela kumamitha angu-6 ukuya ku-7. Isisu samakhosi siqala ukwanda kancane, sinika ingane ithuba lokuthuthukiswa.
- Ekupheleni kwenyanga yesine yokubeletha ingane kufinyelela kumamitha angu-15 kuya ku-16 kuya kwezi-16, kulinganisa amagremu angu-150 futhi ihamba ngesibindi esiswini.
- Ubungako be-fetus emavikini angu-22 buyizingamamitha angu-30, zonke izitho nezinhlelo zisebenza ngokugcwele.
- Amaviki angu-33-36 abhekene nokulungela kwengane ukuzalwa. Ukukhula kufinyelela ku-45-50 amasentimitha, kanti isisindo siyasihluka ku-3-3.5 kg.
Ngesikhathi sokukhulelwa, ikakhulukazi uma kukhona okungajwayelekile kwezokubeletha, kunesidingo sokususa ezinye izinkomba zokuthuthukiswa okuphelele kwe-fetus. Cabanga ngokuyinhloko kubo, okuyinto ethatha ukunakekelwa kwezidakamizwa kanye namagciwane.
Usayizi wekhanda le-Fetal
Ukuthola lezi zikhombisi kuyadingeka ukuthi ucacise isikhathi sokubeletha kanye nokucabanga ukuthi indlela yokulethwa kuyokwenzeka ngayo. Njengoba ikhanda lomntwana eliqala ukungena emithonjeni yokuzalwa kanye nomthwalo walo ophakeme kakhulu, bese uqala ukuma, ubungako nobukhulu kuyindlela ebaluleke kakhulu.
Usayizi we-coccyx-parietal fetal
Lesi sibonakaliso silinganiswa ngaphambi kweviki le-11 lokubeletha, ngoba esikhathini esizayo idatha iyanemba kakhulu. Ngenxa yokulinganisa nokulinganisa idatha ye- CTF ye-fetus, kungenzeka ukuthi useke iminyaka yengane, isisindo sayo esilinganiselwe nobukhulu, amasonto . Lokhu kwenziwa ngosizo lwe-ultrasound.
Ubukhulu be-cerebellum ye-fetus ngamasonto
Ukufunda lezi zikhombisi ezikhathini zokubeletha zakuqala kunika isazi sezimbangi ithuba lokuqondanisa izinga lokuthuthukiswa kanye nobukhulu be-fetus ngesikhathi sokukhulelwa, ukuthola ulwazi olugcwele mayelana nokungaziphathi kahle kwezakhi zofuzo, ukuhlola isimo jikelele somzimba wengane nokunye. I-cerebellum, ngezinga elithile, inesibopho sokubeka okulungile nokuphelele kwezinhlelo nezitho.
Usayizi wangaphambili-wesipilital of head fetal
Lezi zinkomba ziphinde zikwazi ukucacisa isikhathi sokubeletha nokukhomba ukungalingani ngobukhulu be-fetus ngesikhathi sokukhulelwa. Idatha ibalwa ngumshini we-ultrasound noma ngesandla ngokusho kwefomula evamile.
