Yiqiniso, asikwazi ukudweba iziphetho ezicacile, sincike kuphela kulezi zimingcele, njengoba ingane ngayinye inesimiso sayo siqu, kuye ngezici eziningi. Noma kunjalo, umuntu akufanele anakekele izinkomba ezinjalo ezibalulekile. Isibonelo, ngokusho kwesisindo somntwana ungakwazi ukwahlulela impilo ye-fetus, ukutholakala kwamathambo, ukudla okungenele kwezakhi noma ukusongelwa kokukhulelwa.
Kumele uqaphele ukuthi ukulandelela ukuthi ukukhula nesisindo se-fetus kuhluka kanjani ngamasonto okukhulelwa, ungasebenzisa i- ultrasound. Le ndlela ikuvumela ukuba uthole izilinganiso ezinembile kakhulu zengane. Qinisekisa ukuthi umntwana uyakhula futhi uthuthuke ngokuhambisana nesimiso kungenziwa ekuhloleni okujwayelekile, ngemuva kokuba umgogodla wezinzwa wezinyathelo ahlolisise isisu sesisu nokuphakama kokuma kwesibindi sesisu. Phela, lezi zimiso ziyahlukahluka ngokulingana nokukhula kwengane amasonto okukhulelwa. Ngakho-ke, ngaphambi kokukhulelwa, isisu sesifazane onempilo oneminyaka ezayo yokuzala okulinganisa amagremu angu-50-60, ngenkathi ekupheleni kwesikhathi le namba ibanga kusuka ku-1000-1300 amagremu. Okuyinto engokwemvelo, inikezwe ukuthi lo mzimba izinyanga eziyisishiyagalolunye kufanele unikeze izimo ezikhululekile zokuphila. Ngakho-ke, njengoba ingane ikhula, ubukhulu besisu buyakhula ngesonto ngalinye lokukhulelwa.
Izikhathi zokukhula komntwana ngamasonto
Kukhona itafula elikhethekile, elikhombisa amanani okukhula okujwayelekile kanye nesisindo se-fetus ngesonto. Yiqiniso, izindinganiso zangempela zingase zihluke kulabo abonisiwe, ngoba lezi zici zithonywa yizinto ezihlukahlukene, kuhlanganise nokuzalwa. Noma kunjalo, ekudaleni isithombe esivelele salokho okwenzekayo, izincwadi zokukhula kanye nesisindo esivamile, kanye nokuthambekela kokukhula kwawo, kudlala indima ebalulekile. Njengomthetho, ukukala ukukhula kwe-fetus kuqala kuphela phakathi kwe-trimestre yokuqala, ngoba ngesikhathi sokuqala ubukhulu bokubukeka kombungu kusemncane kakhulu.
Kusukela kulo mbono, kuphakanyiswa ukwenza i-ultrasound ngaphambi kweviki lesishiyagalombili.
Kulesi sigaba, ukukhula kwe-fetus kubonisa ibanga ukusuka komqhele kuya kumsila. Ngakho-ke, lobu bukhulu bubizwa ngokuthi i-coccygeal parietal futhi ikhethwe njenge- KTP kuphela. I-KTP ilinganiswa amasonto angu-14 kuya kwangu-20 (kuye ngokuthi isikhundla somntwana namakhono ochwepheshe owenza i-ultrasound) ngoba ngaphambi kwalesi sikhathi imilenze ye-crumb igobile kakhulu futhi akunakwenzeka ukucacisa ubude obuphelele.
Kusukela emasontweni angu-14-20 okukhulelwa, odokotela bazama ukulinganisa ibanga ukusuka ezithende kuya emgqeni.
Amazinga okukhula kwe-Fetal amasonto
Abesifazane abaningi bayashesha ukwenza i-ultrasound ngokushesha ngemva kokubambezeleka. Kulesi simo, i-ultrasound ingaqinisekisa kuphela ukuthi i-egg fetal ikhona emgqeni we-uterine futhi inqume ububanzi bayo. Njengomthetho, ku-6-7 ngesonto lokubeletha lokubeletha, leli xabiso lingu-2-4 mm, futhi ku-10 kuya kwangu-22 mm. Noma kunjalo, indoda yesikhathi esizayo ikhula ngamandla futhi ikhula, ngaleyo ndlela:
- ekupheleni kwamasonto angu-12, i-CTE ye-fetus ingama-6-7 cm;
- Emasontweni amane alandelayo umntwana uzokhula 5 cm;
- futhi emavikini angu-20 ubude obuvela emqhele kuya kwesithende bufinyelela ku-26 cm;
- emavikini angu-24 - 30 cm, futhi ngo-28-35 cm;
- ngeviki elingama-32, i-crumb ingenza i-jump in ukukhula ngo-7 cm;
- Emasontweni angama-36 iningi lezingane lilungele ukuzalwa, izitho zalo nezinhlelo zakhiwa, ziye zathola futhi zakhula. Ngokuyinhloko, ngalesi sikhathi ukukhula kwengane kuwu-45-48 cm;
- Noma kunjalo, amasonto amane asele ngaphambi komhlangano othandekayo, i-crumb ayilahlekelwa yize. Phakathi nalesi sikhathi, izinsana zingeza 100-300 amagremu ngesonto bese zikhula 1-2 cm;
- ukukhula kwengane ephelele esanda kuzalwa kuyohlukahluka ngaphakathi kwamaphesenti angu 48-54 cm.
