Ukukhulelwa konke, ibhinqa lihamba ubuncinane kwiimviwo ezintathu ze-ultrasound ezicwangcisiweyo. Kwiiveki ezingama-32, i- ultrasound ye- fetus yesithathu ehleliweyo . Injongo ephambili yoviwo kukuqinisekisa ukubambezeleka kokuphuhliswa komntwana kunye noviwo lwepentecenta. Njengoko kwiimviwo zangaphambili - kwiiveki ezimashumi amabini anesibini, ugqirha ujonge iiparameters zesigxina sekhanda, isisu, nobukhulu bemilenze yesisu. Qaphela kwakhona inani le-amniotic fluid. Isiqhamo ngeli xesha sithatha isikhundla sokugqibela kwisibeleko.
Ekugqibeleni malunga nophando olwenziweyo ugqirha uchaza, yiyiphi inqanaba lokukhulelwa ukukhulelwa lihambelana, ukuba ubuninzi bezityalo zihambelana nemimiselo emiselweyo yexesha elithile.
I-Ultrasound kwiiveki ezingama-31-32 zokukhulelwa zijoliswe ekufundeni kungekuphela nje umntwana, kodwa kunye ne-placenta. Ingcali ichaza indawo yayo kunye nodonga apho iqhotyoshelweyo khona. Le ngcaciso ibalulekile ukuze kuchongwe indlela yokuhanjiswa kwayo, kwaye ibaluleke ngokukodwa xa kukho izibonakaliso zecandelo elishiyekileyo. Xa uhlolisisa i-placenta, ugqirha okhokelela ukukhulelwa unquma ukulungelelaniswa komsele wokuzalwa wesifazane ekunikezeni.
Ukuqulunqwa kwe-ultrasound kwiiveki ezingama-32 zokukhulelwa
Izibonakaliso ze- ultrasound kwiiveki ezingama-32 zokukhulelwa zifaniswa neetafile ezikhethekileyo, zihlanganiswe ngokuhambelana nemigangatho yokuphuhliswa komntwana kwisithuba esithile sokukhulelwa. Ukuba iiparitha ze-ultrasound kwiiveki ezingama-32 zihluke kwiimpawu eziqhelekileyo kwisinye okanye iiveki ezimbini, oku akukuphambuki. Kubalulekile ukuba uqaphele ukuba umzimba ngamnye uqobo, kwaye imimiselo eyamkelekileyo yimihlangano kuphela. Kwiveki engamashumi amathathu nesibini yokukhula kwezibonakaliso kubonakala ngathi:
- I-BPR - 75-89 mm;
- LZ - 95-113 mm;
- OG - 283-325 mm;
- OZH - 258-314 mm;
- i-humerus - 52-62 mm;
- umphambili - 45-53 mm;
- i-femur - 56-66 mm;
- shin - 52-60 mm.
Ubunzima beqhamo ngeli xesha li malunga ne-1800g, eli nani lingahluka ngamakhulu amabini amagremu kwimiba mibini. Ukukhula komntwana kufinyelela kumasentimitha angamashumi amathathu nantathu kwiiveki ezingamashumi amathathu namibini, kodwa oku kukho umqondiso wesiganeko kwaye umntwana wakho unokuba mfutshane okanye mhlawumbi.
