Ngeveki yama-22 ukuhlolwa kokuhlola kungakhange kwenziwe: ibhinqa kufuneka ihlolwe kwangaphambili kwaye i-ultrasound elandelayo imiselwe kwiiveki ezingama-31. Kwaye kwiiveki ezingama-22, i-ultrasound yenziwa ngabafazi abasetyhini abangazange bahlolwe ngaphambili okanye ngokwemiqondiso. Inyaniso ngeli xesha lingaqhuba iimviwo ezongezelelweyo ze-ultrasound kunye nokubonisana kumaziko ogqirha, ukuba kwakunokukrokrelwa kwangaphambili ukukhubazeka kokuzalwa komntwana. Ukwenza oku, khetha i-ultrasound eqhelekileyo okanye ye-3-D, kwaye iiveki ezingama-22 zokukhulelwa zifanelekile ukuhlolwa, ekubeni ukukhishwa kwesisu ngokukhawuleza kuvunyelwe ukufikelela kwiiveki ezingama-24.
Iiveki ezingama-22 zokukhulelwa - iiparitha ze-ultrasound
Iziphumo ze-ultrasound ekuqaleni kweeveki ezingama-22 zokukhulelwa okanye xa sele sele ziveze iiveki ezingama-22-23 zihluke kakhulu. Ubungakanani obukhulu, obulinganiselwa kwiiveki ezingama-21 ukuya ku-23:
- I-BDP (ubukhulu biparietal yekrele) - ukusuka kwi-51.6 ukuya kwi-54.2 ukuya kwi-54.2 ukuya kwi-57,5 mm;
- DB (ubude bethanga) - ukusuka ku-35.3 - 38.3 ukuya kuma-67 ukuya ku-70 mm;
- I-LTE (ubukhulu beparietal ngobukhulu bekrele) - ukususela kuma-64 ukuya kuma-67 ukuya ku-38.3-41.3 mm;
- I-SJ (ithetha ububanzi besisu) - ukusuka ku-52.5 - 56.4 ukuya kwi-49.4 ukuya kuma-52.6 mm;
- I-SDHK (ububanzi bomyinge wesifuba) - ukusuka kwi-46.4 ukuya kwi-49.4 ukuya kwi-56.4-59.3 mm.
I-placenta eqhelekileyo ngeli xesha lifana kwaye linama-26-28 mm. Ikholomu ye-amniotic fluid endaweni engahlawuliyo intambo yomzimba kunye neengxenye ze-fetus ngu-35-70 mm. Intliziyo ibonakala ngokucacileyo onke amagumbi kunye namagatya,
Isakhiwo sombono sibonakala kakuhle, ububanzi bee-ventricles zangasemva ali-10 mm. Uyabona isibindi, iintso, isisu, isisu kunye nesisu somntwana. Intambo yomlomo ibonisa ngokucacileyo zonke iinqanawa, kodwa ubukho bayo entanyeni asithethi nantoni na: isikhundla se-fetus sisisigxina kwaye sishukunyiswa ngokukhululekile kwi-uterine cavity.
Iiveki ezingama-22 zokukhulelwa yithuba apho isondo somntwana sibonwa yi-ultrasound , kwaye iiparameters zamakhwenkwe kunye namantombazana ahluke ngobunzima.
