Ngexesha le-ultrasound, ubukhulu obuhlukahlukeneyo bomntwana , obubonisa indlela umntwana abumba ngayo, kuyafuneka. Ixesha elilodwa le-gestation lihambelana nobungakanani obuthile, ukutshintshelwa kwinqanaba lokunyuka okanye ukunciphisa kwenza ukuba ucinge ngekhondo lokukhulelwa. Kule nqaku siza kuqwalasela ukuba yintoni ubungakanani be-coccy-parietal yobusana, kuthini na kwaye kufanele kube yinto eqhelekileyo?
Iyintoni i-CTE yomntwana?
Ubungakanani be-fetus-parietal fetal lubekwe ngokuhlolwa kwe-ultrasound kwaye luqhathanise nobunzima bomzimba bomntwana, uqikelele ixesha lokukhulelwa kwaye ulifanise nekota elibalwe yimizuzu yokugqibela. Esi sibonakaliso sinenani elibalulekileyo lokuxilonga ngaphambi kweveki yeshumi elinanye lokukhulelwa (kwezinye iimeko ukuya kwiveki yeshumi elinesithathu), emva koko inkcazo yamanye ubunzima be-fetal iza kuqala. Indlela yokulinganisa ubungakanani be-coccygeal-parietal yobusana ilula, kwaye iquka ukugqiba umgama ukusuka kwithambo leparietal ukuya kwi-coccyx. Kuphawulwe ukuba isalathisi se-coccygeal-parietal size sihamba ngokuthe ngqo kwixesha lokukhulelwa, oko kukuthi, ixesha elide, i-KTR index.
I-Ultrasound ye-fetus - KTR
Ukufumanisa ubungakanani be-coccygeal-parietal nge-ultrasound, kuyimfuneko ukuskena isibeletho kwimilinganiselo eyahlukeneyo kwaye ufumane apho ubude bombindi buza kuba bunkulu. Kule scan, ubungakanani be-coccygeal-parietal kufuneka bamiswe. Ngenxa yokuqulunqwa kobukhulu be-fetal-parietal fetal yi-ultrasound, umhla oqikelelweyo wokunikezelwa usungulwe.
Ubungakanani bepaketali ye-Coccygeal - ngokuqhelekileyo
Ukuchonga ukuba i-embryo ihambelana nobungakanani besikhathi sokubambana, iitheyibhile zenziwe zaza zahlanganiswa ezibonisa ixabiso elithile lobungakanani be-coccygeal-parietal. Ngaloo ndlela, i-CT yomntwana ongama-5 mm ihambelana neveki yesi-5 yokukhulelwa, kunye ne-CT yesisu se-6 mm ifana nesonto lesithandathu lokukhulelwa. Ukuba silandela le nqondiso ngakumbi, sinokubona enye indlela. Ngaloo ndlela, i-CTE ye-fetus kwii-7, 8 neye-9 zeeveki zokugaya zi-10 mm, 16 mm kunye ne-23 mm, ngokulandelanayo. I-KTR fetus 44 mm ibonwa ngokuqhelekileyo kwiiveki ezili-11 zesisu. Ukuba, ngokomzekelo, kwiiveki ezili-12 zesisu, ubungakanani beemfesi ze- coccygeal parietal ngu-52 mm, kwaye ngeveki 13 lihambelana no-66 mm, oku kubonisa ukukhula okukhawulezayo kwembungu.
