Ukukhula kwe-Fetal kuyimfuneko ebalulekile yokuhlola ukuthuthukiswa kwayo. Kanye neminye imingcele yokuhlola, ukukhula kwe-fetus yamaviki kuvumela udokotela ukuthi ahlole ukuthi ukukhulelwa kuphelele kuqhubeka kanjani.
Ngokukhula kwe-fetus yamaviki okukhulelwa, unganquma ukuthi yiziphi izici ze-pathogenic ezithonya ukuthuthukiswa kwengane ezayo. Ukwehla kokukhula kwe-Fetal kungase kubonise ukushiya ngemuva kokuthuthukiswa okuphelele noma ukukhulelwa kokukhulelwa .
Ukukhula kwe-Fetal kubalwa uma owesifazane ewela i-ultrasound, kusukela ekuqaleni kwe-trimester yokuqala yokukhulelwa. Kuze kube yilesi sikhathi, ukukhula kwe-fetus kunzima ukulinganisa ngenxa yobukhulu obungenakubalwa bombungu.
Ukukhula kwe-Fetal kulinganiswa kuze kuphele amasonto angu-12-13 wokubeletha. Kulokhu, ukukhula kwengane kukhonjiswe ekuphethweni kwe-ultrasound okuthiwa usayizi we-coccyx-parietal noma i- KTP , okuyinto ubude bomzimba wengane kusuka ku-coccyx kuya ku temechka (ubude bemilenze abukaliwe lapha).
Ngezigaba kamuva zokukhulelwa, i-trunk nemilenze ye-fetus igobile noma endaweni ehlukile. Ngakho-ke, ubude be-fetus kunzima kakhulu ukulinganisa. Futhi esikhundleni salokho, ezinye izilinganiso zilinganiswa: ubukhulu bezitho, umjikelezo wesisu neshloko, bese uqhathanisa imiphumela nemigomo evamile.
Ukubalwa kokukhula komntwana
Ukubala ukukhula kwe-fetus, ungasebenzisa amafomula akhethekile.
P = 3.75 x H = 0.88 noma P = 10 x P-14 ,
kuphi
- P ukukhula kwe-fetus (cm),
- H - ubude bomlenze wesisu (ubude be-tibia kanye nobude besifazane, cm),
- P ubude be-humerus yesisu (cm).
Inani elijwayelekile lokukhula komntwana wesonto ngalinye lokukhulelwa lingasetshenziswa ngokusebenzisa amatafula akhethekile. Kodwa kufanele kukhunjulwe ukuthi ingane ngayinye ikhula ngabanye futhi idatha, enikezwa ematafuleni, ibonisa amanani okukhula okuphakathi kwamasonto.
Uma, ngokusho kwemiphumela ye-ultrasound, kunqunywa ukuthi umntwana unokukhula okuphezulu noma ngaphansi kwesilinganiso, lokhu akusona isizathu sokukhathazeka.
