I-Ultrasound iyithuba lokuba umama ozayo afunde ukuthi konke kuhambisana nomntanakhe, ukhula kahle, akanalo i-oxygen, futhi nanoma yiliphi i-congenital pathologies. Yingakho imiphumela ye-ultrasound ngesikhathi sokukhulelwa ikhathaza wonke owesifazane osesimweni.
Incazelo yokukhulelwa kwe-US amasonto angu-12
Emasontweni angu-12, owesifazane okhulelwe kuqala ufika e-ultrasound, uma ngaphambi kwalokho wayengenayo izinkinga ngengozi yokukhulelwa kwesisu kanye nesonto leqanda le-fetal. Ngalesi sikhathi, umbungu usengumncane kakhulu, ubude buyi-4 cm kuphela, kepha kunezinkomba ze-ultrasound ngesikhathi sokukhulelwa, okudinga ukuhlolwa. Okokuqala, lokhu kuwubukhulu besikhala sekhanda (ngokuvamile kuya ku-2.5 mm) nobude bethambo lomzimba (okujwayelekile kuya ku-4.2 mm). Izinguquko ngosayizi zingase zibonise ukuphambuka kokuthuthukiswa komntwana futhi zidinga ukubonisana ne-geneticist futhi, mhlawumbe, ukuhlolwa okwengeziwe. Ngaphezu kwalokho, nge-ultrasound emavikini angu-12, isilinganiso sobukhulu be-coccygeal parietal, kufanele sihluke ebangeni kusukela ku-42 kuya ku-59 mm. Kumele kukhunjulwe ukuthi imigomo ye-ultrasound ekukhulelweni ishintshe nsuku zonke nokukhula kwengane, ngakho-ke emavikini angu-12 nosuku oluthathu bayohluka ngendlela ehlukile.
Futhi ngalesi sikhathi, izinga lokushaya kwenhliziyo le-fetus, isimo se-placenta, ubude bomthamo womzimba kanye nenani lezitsha kulo, ukungabi khona kwe-dilatation yomlomo wesibeletho, kanye nokunamathiswa kwe-placenta nezinye izinkomba kubalwa. Dweba i-ultrasound ye-fetus bese ukhetha, uma kunesidingo, ukwelashwa, udokotela wakho angakwazi.
Idatha ye-ultrasound ekukhulelwe emavikini angu-20
Emasontweni angu-20, kwenziwa ucwaningo lwesibili lwe-ultrasound, oluhlola izinkomba eziningi ze-fetometric. Ingane isivele ikhulile futhi awukwazi ukulinganisa usayizi we-coccyx-parietal kuphela, kodwa nobude besifazane, ububanzi besifuba, ubukhulu be-biparietal yekhanda. Ku-ultrasound, izitho zangaphakathi ze-fetus sezivele zibonakala ngokucacile - ngakho-ke nge-ultrasound ngesikhathi sokukhulelwa isiphetho sizoqukatha ulwazi mayelana nenhliziyo, izakhiwo zobuchopho, isisu, izinso namaphaphu wengane. Ukuxilongwa kuzophinde kuphinde kuhlolwe ubuso ukuze kube nesakhiwo esifanele sezakhiwo zobuso, futhi ngokusho kwefomula ekhethekile kuzobala isisindo esilinganiselwe somntwana. I-parameters ye-ultrasound ekukhulelweni izofaka futhi i-placenta nesilinganiso sokuvuthwa kwayo, isimo se-amniotic fluid. Futhi, izinga lokushaya kwenhliziyo lizohlolwa. Imiphumela ye-ultrasound ye-fetus izosiza ekuhloleni ukuthuthukiswa kwengane nokuntuleka kokulahla kokukhula nesisindo.
I-Ultrasound yamaviki angu-32 ukukhishwa - okulotshiwe
Emasontweni angu-32, ngokukhulelwa okungavamile, i-ultrasound yenziwa okokugcina. Ukumiswa kwabafazi abathintekayo kuzophinde kufake izinkomba ze-fetometric (ngaphandle kobukhulu be-coccyx-parietal, ngalesi sikhathi awusasaphenywa), ochwepheshe uzophinde ahlole isimo sezingaphakathi zangaphakathi kanye nokungabikho kwezingqinamba. Ngaphezu kwalokho, kuyokwazi ukuhlola isethulo se-fetus nendawo yokunamathisela kwe-placenta.
Amazwana etafuleni:
I-BRGP (i-BPR) isayizi ye-biparietal yekhanda. I-DB ubude bethanga. I-DGPK ububanzi besifuba. Isisindo - ngogremu, ubude - ngamasentimitha, i-BRGP, i-DB ne-DGRK - ngamamitha.
Uma kukhona izinkomba, i-ultrasound ngesikhathi sokukhulelwa ingenziwa ngaphambi kokubeletha. Kodwa-ke, njengomthetho, lokhu akusadingeki, kungenzeka ukuthi uhlole isimo se-fetal ngosizo lwe-CTG (i-cardiotocography).
Ukumiswa kwemiphumela ye-ultrasound ekukhutheni kufanele kwenziwe ngudokotela ngokucabangela izinkomba ezihlukahlukene kakhulu - isimo somama, imiphumela ye-ultrasound eyedlule (ngaso sonke isikhathi thatha ukucubungula kwazo zonke izinhlobo ze-ultrasound ngesikhathi ukhulelwe) kanye nezici zomthethosisekelo wabazali bobabili (isibonelo, uma umama nobaba bekhula kakhulu, umntwana kungase futhi ikhule ngokujulile kunemigomo ebekiwe). Ngaphezu kwalokho, zonke izingane zihlukile, futhi azikwazi ukuhlangabezana ngokugcwele nezindinganiso ezilinganiselwe. Uma ungabaza ngesinye isibonakaliso, qiniseka ukuthi wabelana nodokotela othembelayo. Uzokutshela ngezici zokuthuthukiswa kwengane noma uzohlinzekela ukwelashwa okwanele.
