Isisindo somntwana ongakazalwa singumgogodla obalulekile ukuze kuhlolwe ukuthi ngabe i-fetus ikhula kahle, ngokugcwele nangokujwayelekile. Kuyisisindo somntwana, odokotela abahlanganisana nezinye izinkomba, ezifana nokuphakama, imingcele yezingxenye zomzimba ngamunye, izintambo, okwenza kube lula ukukhomba isimo samanje sokukhulelwa ngesikhathi esifanele. Ngendlela u-fetus eqoqa ngayo isisindo samasonto, udokotela uyakwazi ukwahlulela ukuthuthukiswa kwengane, kanye nokuthi ivulekile yini kunoma yiziphi izici ze-pathogenic.
Isibonelo, uma ingane ikhula isisindo ngesonto kakhulu ngemuva kwesijwayelekile, khona-ke lokhu kungaba isibonakaliso sendlala, kokubili oksijini nokudla. Indlala yema-oxygen ingaba enganeni uma owesifazane ephuza noma ephuza ngesikhathi sokukhulelwa. Indlala yokudla ingathola ingane ngenxa yokuntuleka kwezakhi ezidingekayo. Ukungabi nesisindo kungase kubonise ukuwohloka okuvamile ekuthuthukiseni i-fetus ngisho nokukhulelwa kukhula .
Okufanayo kusebenza ngesisindo esiningi, okwenzeka ngenxa yezimo ezithile ezingajwayelekile noma ukuphazamiseka ekuthuthukiseni ingane. Yiqiniso, wonke owesifazane nengane yakhe yesikhathi esizayo unesakhiwo esizimele somzimba, ngakho awukwazi ukubeka wonke umuntu ngaphansi kwebha elilodwa.
Yini okufanele isisindo somntwana njalo ngesonto lokukhulelwa?
Ukuze ngandlela-thile uhambe ngendlela yokukhulelwa futhi uqaphe ukuthuthukiswa kwengane, kunezimo ezithile zesisindo se-fetus yamaviki. Ngokujwayelekile, isisindo esiphelele sofusayo sihlolwe ukuhlolwa kwe-ultrasound, okuyindlela enokwethenjelwa ngokunemba okuphelele. Kodwa i-ultrasound ingenziwa izikhathi ezimbalwa kuphela phakathi nesikhathi sonke sokukhulelwa, ngakho odokotela banquma ukuthi isisindo somntwana "sinesisindo" silinganisani, silinganisa ukuphakama kokuma kwesibeletho futhi kulinganisa ukulinganisa okuphelele kwesisu.
Ukuze ungalokothi ulahlekelwe ngokuqagela, kungakanani ingane okufanele isilinganise ngesikhathi esithile sokukhulelwa, kunetafula ekhethekile yesisindo se-fetus yamaviki:
| Ukukhulelwa, isonto | Isisindo somsana, g | Ubude be-Fetal, mm | Ukukhulelwa, isonto | Isisindo somsana, g | Ubude be-Fetal, mm |
| I-8 | 1 | 1.6 | 25 | 660 | 34.6 |
| 9th | 2 | 2.3 | 26 | 760 | 35.6 |
| 10 | 4 | 3.1 | 27 | 875 | 36.6 |
| 11 | I-7 | 4.1 | 28 | 1005 | 37.6 |
| I-12 | 14th | 5.4 | 29 | 1153 | 38.6 |
| 13th | 23 | 7.4 | 30 | 1319 | 39.9 |
| 14th | 43 | 8.7 | 31 | 1502 | 41.1 |
| 15 | 70 | 10.1 | 32 | 1702 | 42.4 |
| 16 | 100 | 11.6 | 33 | 1918 | 43.7 |
| 17th | 140 | 13th | 34 | 2146 | 45 |
| I-18 | 190 | 14.2 | 35 | 2383 | 46.2 |
| 19 | 240 | 15.3 | 36 | 2622 | 47.4 |
| 20 | 300 | 16.4 | 37 | 2859 | 48.6 |
| 21 | 360 | 26.7 | 38 | 3083 | 49.8 |

| 24 | 600 | 30 | 41 | 3597 | 51.7 |
Kodwa kubalulekile ukukhumbula ukuthi izinkomba ezinjalo azilona iqiniso, kodwa zikhombisa kuphela. Ngakho-ke, uma uhlola isimo somntwana jikelele, akufanelekile ukwenza iziphetho ezisheshayo. Ngaphezu kwalokho, inhlolovo enjalo kufanele yenziwe ngumchwepheshe oqeqeshiwe.
Ngokuvamile ingane ebelethwe isisindo esivela ku-3, 1 kg kuya ku-3, 6 kg. Kodwa kunezingane futhi zinesisindo esikhulu, ngoba isakhiwo somzimba wengane sithinteka yizici eziningana:
- ubulili bomntwana;
- ukudla okunomsoco, isimo sezempilo kanye nokuba khona kwemikhuba eyingozi yowesifazane okhulelwe;
- ukwelashwa okungenzeka ngesikhathi sokukhulelwa;
- inani lezingane esibelethweni.
Isisindo somsana emva kwesonto lama-20 lokukhulelwa
Ngaphambi kweviki lama-20, isisindo somntwana ongakazalwa asikhulu kakhulu futhi sitholwa kancane kancane. Kodwa kakade emavikini angu-20 isisindo sesithelo singamagremu angama-300, futhi emavikini angu-30 umntwana unesisindo esingaphezulu kilogram. Lokhu kuhle, kodwa uma ukwanda okunjalo kwesisindo kungagcinwa, kufanelekile ukunakekelwa okukhethekile lokhu futhi uthole izizathu zokuthuthukiswa okunganele kwezingane. Ngesonto lama-38 lokukhulelwa, isisindo somntwana kufanele sibe okungenani noma sibe ngu-3 kg kilo, okukhombisa ukuthuthukiswa okujwayelekile kwengane nokulungela kwakhe ukuzalwa.
