Umthamo wekhanda le-fetal lihluka kanjani ngesonto?
I-fetal head circumference, njengezinye izinkomba, ihluka ngamaviki okukhulelwa. Ngesikhathi se-ultrasound yokuqala, emavikini angu-12-13 kungama-95-96 mm. Ngesikhathi esifanayo, phakathi naso sonke isikhathi sokubeletha ingane, ikhanda lakhe likhula ngamazinga ahlukene, isb. ukukhula kwehlisa kancane, bese kuqinisa.
Ngakho-ke, ukwanda okukhulu kule parameter yentuthuko ye-intrauterine kubonakala ku-2 trimester yokukhulelwa. Ngalesi sikhathi, ikakhulukazi kusukela emavikini angu-15 ukuya kwangu-26, leli pharamitha landa ngo-12-13 mm njalo ngesonto. Khona-ke izinga lokukhula liyehla. Cishe inyanga eyodwa ngaphambi kokuvela kwengane, iyakhula ngo-13-15 mm kuphela.
Umthamo wekhanda le-fetal ulinganisiwe kanjani?
Ukukala kwalesi parameter kwengane kwenziwa ngokusebenzisa umshini we-ultrasound. Kulesi simo, isifundo senziwa ngamaphuzu amaningana ukuze uthole umphumela onembile kakhulu. Njengoba sekushiwo kakade, leli pharamitha lifakwe eqenjini lezinkomba ze-fetometric, elihlanganisa ubude be-hip, isisu somzimba, ubude be-fetus nesisindo sayo.
Imiphumela yokulinganisa ihlolwe kanjani?
Ukuze uhlole ubukhulu bekhanda lekhanda le-fetal, itafula lahlanganiswa, okubonisa ukuthi kuvamile-ukulinganisa okuvamile kwalesi parameter, okuhambisana nesigaba esithile sokuthuthukiswa kwe-intrauterine.
Udokotela uhlola imiphumela yokulinganisa, ecabangela ezinye, izinkomba ezibalulekile zokuthuthukiswa kwengane. Ngesikhathi esifanayo, akukho okubophezela ngokuqinile kumapharamitha athile, ngoba umzimba ngamunye ungumuntu ngamunye. Kodwa, naphezu kwalokhu, kunemikhawulo okuthiwa yizinkambiso, okungaphezu kwalokho okungakhuluma ngokuthuthukiswa kwephulwa.
Kuyini ukuphambuka kobukhulu bezingqimba zekhanda kusuka kuvamile?
Njengoba kuyaziwa, ngokuvamile noma yikuphi ukuphambuka okuvela kumkhuba walokhu noma lokho okubonisa ukuthuthukiswa kwe-intrauterine kwengane kufakazela ukuthi kukhona ukwephulwa. Esimweni esinjalo, umsebenzi oyinhloko odokotela ukuwukhomba nokuwulungisa ekuqaleni.
Ngakho-ke, isibonelo, isikhulu esikhulu sekhanda ebusweni singase sibe uphawu lwesifo esifana ne-hydrocephalus. Kukhona ekuqoqeni ketshezi emgodini ongasebenzi. Kulesi simo, ubuchopho buphuthumayo, ngenxa yokwehla kwesayizi. Ngemuva kokuzalwa kwengane, ukukhishwa kwesikhashana kwenziwa masinyane, ukuze kususwe umthamo oqoqiwe futhi kunciphise ukucindezela okungahambi kahle, okusiza isimo sezinhlanzi.
Kodwa-ke, ezimweni eziningi, ukwanda kwevolumu yekhanda kubhekwe ngezici eziqondene nokuthuthukiswa kwe-fetus. Ngakho-ke, uma abazali bomntwana benemigomo ephakeme yokuthuthukiswa ngokomzimba, kungenzeka ukuthi umntwana uzoba mkhulu.
Ezimweni lapho ingane yesikhathi esizayo ine-circumference enkulu yekhanda, inqubo yokukhiqiza inezici zayo.
Ngakho-ke, kungashiwo ukuthi ukuzungeza ikhanda akuyona nje ipharamitha ebalulekile yokuthuthukiswa komntwana, kodwa futhi isici esingenakunakekelwa ekulethwa kwezidingo. Phela, uma ngesikhathi se-ultrasound itholakala ukuthi owesifazane unomntwana omkhulu, ngakho-ke uma kunezibonakaliso, isigaba sokulinda esilungiselelwe singacelwa. Lokhu kwenziwa ukuvimbela ukuthuthukiswa kwezinkinga.
