I-Ultrasound iyingxenye yezinga legolide lokuhlolwa kokukhulelwa futhi alimazi kumama nomntwana. Kusisiza ukuqaphela kusenesikhathi ukungahle kwenzeke kokuthuthukiswa komntwana, ukukhubazeka kofuzo (isb., Isifo se-Down) futhi kuvumela ukuphazamiseka kokukhulelwa esikhathini esingangamaviki angu-12. Ngezigaba zamuva ze-uzi, ukuhlolwa ngesikhathi sokukhulelwa kuhlolwe ukwakheka komntwana okungaphezulu, ukuhambisana nobukhulu bayo, iminyaka yokugaya, nesimo se-placenta.
Ukuhlolwa kokuqala kwe-ultrasound ekukhulelweni
Ukuhlolwa kokuqala kwe-ultrasound ngesikhathi sokukhulelwa kwenziwa ngesikhathi semasonto angu-9-13. Kuyindlela ebaluleke kakhulu yokuxilongwa, okwenza kube lula ukukhipha ukukhubazeka okukhulu emntwaneni. Phakathi nalesi sikhathi sokukhulelwa, izitho eziningi nezakhiwo ze-anatomical ze-fetus sezivele zibonakala. Ku-ultrasound yokuqala, ungabona okulandelayo:
- inani lezithelo, indawo yokunamathiswa kwe-placenta, ukuhlola isimo samangqamuzana amniotic. Uma ukukhulelwa okuningi kunaka inani le-placentas (ngamawele kukhona i-placenta eyodwa ejwayelekile, ngamawele ahlukene);
- anqume iminyaka yobudala kanye nosuku olulindelekile lokudiliva;
- ukuhlola ukufaneleka kwe-placenta nokubunjwa kwentambo yomlomo;
- ukudalula izimpawu zeziphambeko ze-chromosomal. Nge-ultrasound ye-fetus ene-Down's syndrome, ungabona: izikhala ezingavamile zamathambo asempumeni, ukuqina okwenyuka kwesikhala sekhalenda, ushintsho ekugezeni kwegazi nge-valve ye-tricuspid).
- ukuhlonza inani lezinsalela ze-fetus;
- nezinye izimo eziyingozi (isongo sokukhipha izisu, izimpawu zokuphazamiseka okuphazamisayo).
Ukuhlolwa kokuqala kwe-ultrasound ye-fetus, naphezu kokuqaliswa kwayo ngokucophelela, ayikwazi ukunikeza isiqinisekiso esingu-100% sokungabikho kwamaphutha emfubus ngenxa yobukhulu obukhulu kakhulu.
Ukuhlolwa kokubili kwe-ultrasound kwabesifazane abakhulelwe
Ukuhlolwa kwesibili kwe-ultrasound ye-fetus kwenziwa ngeviki le-19-23 lokukhulelwa futhi kuvumela ukuhlolwa okunembile kokufaneleka kwesakhiwo sezitho zangasese. Phakathi nokuhlolwa kwesibili kwe-ultrasound ngesikhathi ukhulelwe, unga:
- ukuthola isikhathi esiqondile sokukhulelwa;
- ukuzimisela kwesimo kanye nengxenye yamanje ye-fetus;
- anqume ubulili bomntwana;
- hlola indawo kanye nesimo se-placenta;
- unquma inani le-amniotic fluid;
- ukunquma isimo somlomo wesibeletho.
I-ultrasound yobuchopho be-fetal ivumela ukuthi ingabandakanyi izimo eziphuthumayo zokuthuthukiswa kwayo, ukubona izakhi ze-lateral kanye nama-plexuses azo, ubuchopho obuphakathi kanye ne-posterior cranial fossa. I-ultrasound yobuchopho be-fetal yenziwa ngokulandelana emqondisweni we-craniocaudal (kusuka phezulu phezulu).
Ukuhlolwa kwesithathu kwe-ultrasound ukukhulelwa
Ukuhlolwa kwesithathu kwe-ultrasound kokukhulelwa kwenziwa emavikini angu 32-34. Kanye ne-ultrasound, i-dopplerography ne-carotocography eyenziwa, evumela ukuhlola isimo sesisu somntwana nesimo se-placenta. Ngosizo lwe-ultrasound kungenzeka:
- ukudalula izinkinga ze-fetus;
- ukucacisa isikhundla nesethulo somntwana, okungenzeka kube khona ukungena emgodini;
- ukubala isisindo esilinganiselwayo nokukhula kwe-fetus;
- ukuhlola ukufanelana kwe-fetus kuze kube sesikhathini sokubeletha;
- ukuhlola isimo sokusebenza se-placenta nesakhiwo sayo (ubuningi, ukuqina, ukuvuthwa);
- ukukala inani le-amniotic fluid;
- hlola isimo somlomo wesibeletho;
- kulabo besifazane abanesigaba se-cearean emlandweni, bahlole ukuqina kwesibindi esibelethweni.
Ngemuva kwe-ultrasound yesithathu owesifazane okhulelwe kunqunywe ngaphambili kwamacebo wokudiliva.
Ngakho, sibheke enye yezindlela zokwenza ukuhlolwa ngesikhathi sokukhulelwa. Njengoba ubona, i-ultrasound iyindlela yokwelapha ebalulekile ekudaluleni izifo kuzo zonke izinyanga ezintathu zokukhulelwa, ivumela ukuhlola isimo se-placenta ne-fetus, nokwenza isikhathi esiqondile sokukhulelwa.
