Ngesikhathi se-ultrasound, ubukhulu obuhlukahlukene bomntwana , obonisa indlela ingane eyakhiwa ngayo, kunqunyelwe. Isikhathi ngasinye sokukhulelwa sihambisana nosayizi othize, ukuguqula ekuqondeni ukwanda noma ukwehlisa kwenza ucabange ngenkambo yokukhulelwa. Kulesi sihloko sizocabangela ukuthi yiliphi uhlamvu lwe-coccyx-parietal lwe-fetus, lithini nokuthi kufanele luvame kanjani?
Iyini i-CTE ye-fetus?
Ubukhulu be-fetus ye-coccyx-parietal bunqunywa ukuhlolwa kwe-ultrasound futhi kuqhathaniswa nesisindo somzimba we-fetus, sinquma ubude bokukhulelwa futhi siwuqhathanise negama elibalwe yisikhathi sokugcina. Lesi sibonakaliso sinenani elibalulekile lokuxilonga ngaphambi kweviki leshumi nesishiyagalombili lokukhulelwa (kwezinye izimo kuze kube sevikini leshumi nesithathu), emva kwalokho incazelo yezinye ubukhulu be-fetal izofika kuqala. Indlela yokulinganisa usayizi we-coccygeal-parietal we-fetus ilula kakhulu, futhi iqukethe ekunqumeni ibanga ukusuka emthini weparietal kuya ku-coccyx. Kuphawulwe ukuthi inkomba ye-coccygeal-parietal usayizi ngokuqondile ngokulingana nobude bokukhulelwa, okungukuthi, isikhathi eside, isikhathi se-KTR siphezulu.
I-Ultrasound ye-fetus - KTR
Ukuze unqume usayizi we-coccygeal-parietal nge-ultrasound, kuyadingeka ukuskena isibeletho ekuhloleni okuhlukahlukene futhi ukuthola lowo ubude bombungu buzoba bukhulu kunabo bonke. Kule scan, usayizi we-coccygeal-parietal kufanele wenziwe. Ngenxa yokuzimisela komswakama we-coccygeal-parietal fetal nge-ultrasound, usuku olulinganisiwe lokudiliva luyasungulwa.
Usayizi we-coccygeal parietal - evamile
Ukuze unqume ukuthi i-embryo ihambelana nesikhathi sokubeletha, amathebula asetshiwe futhi ahlanganiswa abonisa inani elithile lobungani be-coccygeal-parietal lapho isikhathi sokubeletha khona. Ngakho-ke, i-CT ye-fetus ye-5 mm ihambisana neviki lesi-5 lokukhulelwa, kanti i-CT yesisu somama we-6 mm ihambisana nesonto lesithupha lokukhulelwa. Uma silandela le nkomba ngokuqhubekayo, singabona esinye isenzo. Ngakho-ke, i-CTE ye-fetus emavikini angu-7, 8 no-9 wokubeletha ayi-10 mm, 16 mm no-23 mm, ngokulandelana. I-KTR fetus 44 mm ibonakala ngokujwayelekile emasontweni angu-11 wokubeletha. Uma, ngokwesibonelo, emavikini angu-12 wokubeletha, ubukhulu bezintambo ze-parietal ye- coccygeal ngu-52 mm, futhi ngeviki 13 lihambisana no-66 mm, lokhu kubonisa ukukhula okusheshayo kombungu.
