Ukususela kwiiveki ezingama-24 zokukhulelwa, umntwana uqala ukukhula ngokukhawuleza kwaye akhule ngokukhawuleza. Ngokuqhelekileyo, ama-mama anikwe i-ultrasound kwiminyaka eyi-31 ukuya kwe-32 yokukhulelwa ukuze kuqinisekiswe ukuba konke kulungile nomntwana. Ngokuhlolwa kwe-ultrasound ngeli xesha, kuya kubonakala ukuba umntwana ulinganisa i-kilogram enye neekhilomitha amathathu, kunye nokuphakama komntwana malunga neentimitha ezingama-45.
Ukuqhathaniswa nophando lwangaphambili, i-ultrasound kwiiveki ezingama-31 zesigxina sibonisa ukuba ingqondo yomntwana ikhula ngokukhawuleza, nto leyo ibangela ukubunjwa kwenkqubo ye-nervous. Kwakhona, iris yamehlo yasungulwa, ebonakala ngokugqithiseleyo nge- 3D ultrasound kwiiveki ezingama-31 zesisu. Ngomzekelo omude, kwenzeka ukuba umntwana uhlanganisa ubuso bakhe kunye nezixhobo ezisuka kwimimandla yefowuni ye-ultrasound. Enyanisweni, abazali abaninzi bafuna ukubona iimpawu zabo zentsana, bhala yonke into kwi-disc, bathathe imifanekiso embalwa. Kodwa kukho iimeko apho ubuchwepheshe bezinto ezinqamlekileyo abukwazi ukubonisa umntwana kwiinkcukacha ezincinci:
- ibhinqa elikhulelweyo linokuluhlu oluphezulu lwamafutha;
- Ukungabikho kwamanzi amniotic kuphazamisa;
- Ngethuba lokutyelela ugqirha, umntwana uthabatha indawo engabonakaliyo yophando.
Ngoko ke, kungcono ukwenza i-ultrasound elula kwaye ungayithuthuli umntwana. Emva kwakho konke, usenalo ixesha lokubonga xa usana luzalwa, kwaye kungabalulekanga kwinto ethile.
Iziphumo eziqhelekileyo ze-ultrasound kwiiveki ezingama-31 zesisu
Kwithuba emva kweiveki ezingamashumi amathathu, umntwana akufanele awele emva kwemimiselo esekwe. Yingakho, ngexesha lokukhulelwa kwiiveki ezingama-30 ukuya kwe-31, i-ultrasound yenziwa, ngoncedo apho ubukhulu bomntwana bubonakala khona. Ngoko, yiyiphi into ekumele ibe yi-fetometry kwiiveki ezingama-31:
- Ubungakanani biparietal kufuneka bube ubuncinane ngamamitha angama-73, kodwa angabi ngaphezu kwama-87;
- Ubungakanani bokuqala-wesipiliti kufuneka bube ukusuka kwi-273 ukuya ku-315 mm;
- umjikelezo wentloko yomntwana ukusuka ku-280 ukuya ku-300 mm;
- Umjikelezo wesisu kufuneka ube phakathi kwama-247 no-301 mm.
Kwakhona, xa wenza i-ultrasound, ugqirha ubuka ubukhulu bamathambo omude omntwana. Ngaphantsi kophuhliso oluqhelekileyo, iipameters ziya kuba ngolu hlobo:
- ubude besifa-ukususela kuma-54 ukuya kuma-64 mm;
- ubude be-humerus - ukusuka kuma-50 ukuya kuma-60 mm;
- ubude bethambo lesangqa - 44-52mm;
- ubude bamathambo buyi-51-59 mm.
Ukuba uphando lwe-ultrasound lubonisa ukuba umntwana akahlali kakuhle, ugqirha ugqiba imbangela yale ngxaki kwaye ubeka unyango. Kungaba ukutya, ukuphumla kombhede, unyango esibhedlele. Kodwa nangona kunjalo, iindlela zonyango zikhethwe kwiimeko nganye ngokwahlukileyo. Ngoko ke, bafazi abathandekayo, tyelela ugqirha rhoqo ukuze uhlolwe rhoqo kwaye yonke into iya kulungile!
