Kwisiqingatha sesibini sokukhulelwa umntwana uhamba ngokukhawuleza (umfazi ubalwa ukuya ku-15 ukunyakaza ngeyure), uqala ukukhula ngokunyanisekileyo nokunyusa. Ubusana kwiiveki ezingama-26 uva kakuhle kwaye uphendule kwizwi lomama. Ubude bomntwana kwiiveki ezingama-26 bubungama-32 cm, ubukhulu bayo buyi-900 g.
Ukukhulelwa, okuqhubekayo ngokuqhelekileyo, akuchaphazeli ukuphila komama. Akufanele kubekho ukuvuvukala emilenzeni, ubukhulu bomntwana emasontweni angama-26 bubuncinane ukuba bungavimbeli ukuphuma kweentso. Kodwa ukuba kukho naziphi na iimpawu, kufuneka uhambe kwi-gynecologist ukuze uviwo luqhutywe kanye kwiiveki ezimbini ngeli xesha.
I-Fetus kwiiveki ezingama-25 ukuya ku-26 zokukhulelwa
Kule mihla, umntwana kufuneka abonise ubukhulu be-ultrasound elandelayo:
- I-BDP ( ubukhulu biparietal yekrele ) - 63.0 - 65.1 mm;
- I-LTE (ubukhulu beparietal ngobukhulu bekrele) - 78 - 83 mm;
- I-SJ (ububanzi bentsholongwane yesisu) - 66.1 - 68.9 mm;
- I-SDHK (isisindo somlinganiselo wesifuba) - 58.6 - 60.7 mm;
- DB (ubude bethanga) - 46.1 - 48.0 mm;
- Ubungakanani be-placenta ngu-29.3 - 30.0 mm, ngokufanayo, ngaphandle kokubala okanye i-cysts.
I-fetus kwiiveki ezingama-26-27 zokukhulelwa (ubukhulu be-ultrasound)
- BDP (ubukhulu biparietal yekrele) - 65.1 - 69.2 mm;
- I-LTE (ubukhulu beparietal ngobukhulu bekhayi) - 83 - 88 mm;
- I-SJ (ububanzi bentsholongwane yesisu) - 68.9 - 71.3 mm;
- SDHK (ububanzi bomyinge wesifuba) - 60.7 - 62.9 mm;
- I-DB (ubude be-hip) - 48,0 - 50,9 mm;
- Ubungakanani be-placenta buyi-30.6 ukuya kwi-32.6 mm, ngokufanayo, ngaphandle kokubala okanye i-cysts.
Inani (ubude bekholomu) ye-amniotic fluid kufuneka ibe ngaphakathi kwe-35 ukuya kuma-70 mm. Intambo yesibindi kufuneka ibe neenqwelo ezi-3. Eentliziyweni zonke ezine amagumbi kunye nazo zonke iiguvayi zibonakala ngokucacileyo, ikhondo leenqanawa ezinkulu (i-aorta kunye nomzobo we-pulmary) kufuneka lichane. Inqanaba lentliziyo kufuneka libe phakathi kwe-120-160 ngomzuzu, isigqi sigqibo.
Ukunyuka komntwana kufanele kubonakale ngokucacileyo kwi-ultrasound, intloko yesifo (ingaphantsi kancinci), intloko iqhutywe phambili (ngaphandle kwandiso). Naluphina utshintsho kwisayizi ngaphantsi lungabonisa isifo se-retard syndrome, kwindlela ekunyuka ngayo-mhlawumbi ubunzima obunzima bomntwana okanye ixesha elichanekileyo lokunyanyiswa.
