Ultrasound Screening 1 yokuthathu: kulungiswa imiphumela. is ultrasound ukuhlolwa kanjani 1 yokuthathu?

I Ukuhlolwa kokuqala enikezwa ukuthola kombungu, ukuhlaziya indawo esinomhlapho ukugeleza kwegazi, kanye ukucacisa khona kwezinso zofuzo. Ultrasound Screening 1 yokuthathu kwenziwe isikhathi esingamasonto 10-14 kuphela kadokotela.

Uyini-ultrasound ngo senyanga yokuqala?

US eliyifa okwenzeka wahlomisa ngokukhethekile emitholampilo yangasese noma imitholampilo womama, okuyinto ochwepheshe olufanele abakwaziyo ukwenza uphethwe kunesidingo.

Ukuze aqhube luhlolo egcwele esiteji elincane sokukhulelwa kusiza ultrasound Ukuhlolwa 1 yokuthathu. Injani ucwaningo, kuchaza udokotela, uma kunesidingo, yena uzokutshela indlela yokulungiselela enifeza ukuhlola.

cwaningo Screening kwenziwe indlela transabdominal (ogangeni besisu) usebenzisa ultrasonic apharathasi zokuxilonga. Esikhathini imizuzu yokugcina ultrasound aqukethe nemingcele ezilandelayo:

• ikakhulukazi lesizalo isakhiwo kanye ezihlobene;
• Okubona ne-fetus ube isikhuphasha sac;
• indawo kanye chorion isakhiwo;
• fetus kwenhliziyo imvamisa;
• usayizi isithelo umqhele iqolo;
• ukushuba emphecweni entanyeni.

Ultrasound Uchwepheshe uzokwazi ukucacisa ngqo yobudala sokukhulelwa, siqambe iyiphi nezifo ngenxa yezakhi zofuzo kanye kombungu umbungu, kanye ukubona uma kukhona abesifazane kule zokuzala isifo uhlelo ezingaba izinkinga zokukhulelwa noma kubangele ukuphazamiseka. US-senyanga Ukuhlolwa 1 inikeza ngokugcwele Ukuhlolwa owesifazane okhulelwe bese lowo umbungu kuzo zonke nemingcele ezidingekayo.

Kulungiswa imingcele eyinhloko ultrasound

Ngaphambi kokuqala uphethwe udokotela kumele icacise usuku kokuqala zokugcina esikhathini, ukuze ikwazi ukuqinisekisa ukuthi ubukhulu fetus ekukhulelweni. Ukususa ukubethela kunesithembiso ngqo udokotela ngubani onolwazi wonke amagama nokwazi imithetho wokukhula kwengane esiswini.

Amapharamitha ezibaluleke kakhulu yilezi ukuvama ukuhlolwa lokuqala ukushaya kwenhliziyo coccyx-parietal isinqumo fetus. CHCHS kusuka 10 kuya 14 ngesonto ingase iqale 150-175 amabhithi / ngomzuzu.

Usayizi we-fetus kusukela umqhele iqolo amasonto 13 e isikhathi kufanele okungenani 45 mm. Ultrasound Screening 1 yokuthathu kumele kwenziwe amasonto 13, izinsuku 6, ngoba esikhathini esizayo kuyoba nzima anqume imikhuba namazinga ukuthi amapharamitha umbungu yamukelwe.

Ukususa ukubethela ezengeziwe ultrasound nemingcele

Ukuba khona kwe-fetus chromosomal kwakuphambene nemvelo eshiwo ukujiya nuchal. Le nkomba iyakunikeza senyanga 1 kuphela ukuhlolwa. kanjani ultrasound, kungatholakala kuyi-Internet noma ucele udokotela wakho.

Ukuhlaziya isakhiwo futhi ilungiselelo chorion ukunquma kuzo placenta esizayo ukunquma njengoba ukukhulelwa eba. Kubalulekile ukwazi ukuthi uma chorion enamathiselwe eduze os yangaphakathi kwesibeletho, kukhona amathuba placenta previa.

Isikhuphasha sac amasonto 12 neutralized cishe ngokuphelele, njengoba ngaleso sikhathi-placenta uqala uvuthwe, okuzokwenza lokwenza yonke imisebenzi efanayo futhi ukuqinisekisa i-fetus izakhi futhi wonke lamakhono abalulekile ukuze zikhule kahle zezici.

Uhlaziyo isimo umthondo lensikazi nakho kubalulekile kakhulu. Kusukela ifomu angajwayelekile kwesibeletho (sehhashi, ezimbili esinezimpondo) kungabangela isisu noma wokudamba fetus. Epididymis lase futhi bahlola i-khona izinhlumba. Kwezinye izimo, ngesikhathi sokukhulelwa kukhona isidingo ukuhlinzwa ukhishwe isifo.

Ukuze uthole incazelo wathola kwezinso udokotela uzist ufake amazwana ekupheleni protocol. Ultrasound Screening 1 yokuthathu kwenziwa ucwaningo kubaluleke kakhulu elivumela ukuhlonza ngokugcwele zonke zokugula kungenzeka futhi kwezinso fetus Izitho zokuzala abakhulelwe.

Izici ukuqeqeshwa ukuqhuba ultrasound

Ngaphambi inqubo ayidingekile ukuhambisana ne ukudla ezikhethekile noma purgation. Owesifazane kufanele kuphela thatha ithawula cwaningo ultrasound kanye inabukeni zalutho. Lapho uqala uvakashele ihhovisi US kumele ulinde esinyeni ukugcwaliswa ezincane.

Kuvele udokotela abanolwazi uzokwazi ngesikhathi esifanele ihlonze noma yibuphi, ngisho inkinga encane futhi ukukulungisa ngempumelelo, ngaphandle kokudala into engalimaza ingane ekhulayo esibelethweni noma impilo kamama.

Kusukela ngomhla ka-ultrasound ukuhlonza Down Syndrome?

Intamo uwasonge isikhathi esingamasonto 11-13, akufanele idlule 3 mm. Sokuqonda ultrasound Ukuhlolwa 1 yokuthathu kufanele wenziwe ngudokotela wakho, owazi wonke izici ngamunye umzimba.

Ngaphezu kwalokho nuchal ukucacisa khona Down Syndrome kungaba ezintweni ezifana:

• ukungabikho ithambo acinene;
• ukwephulwa kwegazi flow venosus ductus;
• khona tachycardia (palpitations);
• ukunciphisa ubukhulu maxilla;
• Usayizi anda kwesinye;
• ukungabikho Umthambo yesibili enkabeni (ngokuvamile kube imithambo emibili enkabeni anikeza igazi ligeleze lemali umbungu eziyikho nezanele ka mpilo nezakhi).

Kufanele kuqashelwe ukuthi izinkomba ezithile kungaba futhi zenzeka banezingane eziphile kahle. Ikakhulukazi kumayelana ukutholakala acinene ithambo, okuyinto engekho esikhathini 11 ngesonto cishe 2% izingane. ukwephulwa wegazi ukugeleza kwenzeka 5% izingane enempilo futhi akuyona zokugula ukuthi edinga wezokwelapha.

Kuyadingeka ukuba ahlaziye ngokucophelela imiphumela ukuhlolwa 1 yokuthathu. Ultrasound ayikwazi ngaso sonke isikhathi ukuze abonise isithombe esiphelele kwengane.

Ukulungiselela ukuhlolwa kwamakhemikhali

Ngaphambi kokuqala ukuthatha inkambo igazi umthambo kumele kube usuku ngaphambi inhlolovo ukulandela ukudla ukudla okuthile futhi ukhiphe:

• ushokoledi;
• kwasolwandle;
• ukudla okunamafutha;
• imikhiqizo inyama.

Ngaphakathi 4 amahora ngaphambi igazi amasampuli kuyadingeka ukulishiya ngokuphelele ekudleni. It ivumela ukunikeza umphumela olunembile kakhulu.

1 yokuthathu Ukuhlolwa: ultrasound negazi ngendlela izinkomba zezempilo-fetus sika

Ngo senyanga yokuqala kunesidingo hhayi kuphela ultrasound, kodwa qiniseka ukuthi aphenye igazi umthambo, okuyinto kunqunywa ezingeni hCG futhi PAPP-A.

Esikhathini sitholakele igazi kunqunywa hCG Imininingwane hhayi kuphela, kodwa yayo khulula β-subunit. Ngokuvamile, le nkomba kunoma iyiphi laboratory kufanele ibe uhla 0.5-2 IOM. Uma wephula imithetho kakhulu kwandisa ingozi okubonakalisa umbungu Down Syndrome, noma ezihlukahlukene chromosomal kwezinso.

Yandisa izinga khulula β-subunit ka hCG kusikisela ukuba khona kungenzeka umbungu Down Syndrome. Nakuba ukuncipha lokuhlushwa lokhu Inkomba kwandisa ingozi umntwana Edwards syndrome.

PAPP-A yilona plasmatic amaprotheni A, ezihambisana nokukhulelwa. Ukwanda ezilinganiselwe kule Inkomba ubonisa evamile ngesikhathi sokukhulelwa. Ukuphambuka kusuka kuyinsakavukela kubonisa khona kwezinso umbungu. Nokho, lokhu kusebenza kuphela ongaphakeme igazi inkomba lokuhlushwa esingaphansi 0.5 umama, beyizidlova yinto evamile 2 umama akuyona engozini sokuthuthukiswa ingane.

1 yokuthathu Ukuhlolwa: sokuqonda imiphumela ultrasound futhi ukuhlolwa ingozi pathologies

Laboratories babe nezinhlelo ze-computer ekhethekile, okuyinto ebukhoneni izinkomba ngabanye ibalwa ingozi chromosomal iziyaluyalu. Ukuze izinkomba ngabanye zihlanganisa:

• mbuzeni
• isisindo;
• imikhuba emibi;
• isifo esingelapheki noma unina sokugembula.

Ngemuva kokufaka yonke imingcele ohlelweni ngeke ukubala hCG lesemkhatsini kanye PAPP eqondene yobudala sokukhulelwa futhi abale ingozi kombungu. Ngokwesibonelo, isilinganiso 1: 200 utjengisa bona owesifazana abakhulelwayo 200 1 izingane ziyoba kwezinso chromosomal, nezingane 199 bazalwa engumqemane.

Ukuhlolwa negative kubonisa ingozi iphansi umbungu Down Syndrome futhi Akudingi ukuhlolwa eyengeziwe. Ukulandela luhlolo ngumuntu owesifazane ultrasound ngo senyanga yesibili.

Kuye isilinganiso etholwe endaweni yokucwaninga kunikezwa esiphethweni. Kungaba kuhle noma kube kubi. Ukuhlolwa omuhle ubonisa awokuthi kokuba ingane ene-Down syndrome, ngaleso sikhathi udokotela ekunika izifundo ezengeziwe (amniocentesis futhi chorionic villus amasampuli) ukwenza uphethwe wokugcina.

Ultrasound Screening 1 yokuthathu, ukubuyekezwa okukuvumela owesifazane ezingaphezu kuka ukuqonda imiphumela eyatholakala, ngaso sonke isikhathi kufanele athathwe ngokungathi sína, ngoba kuphela udokotela angaba kahle wokufunda protocol.

Yini okufanele yenziwe usengozini enkulu yokusebenzisa Down Syndrome?

Phezu ukuthola ingozi eliphezulu wokuba ingane engenampilo akufanele ngokushesha iphendukele izinyathelo kakhulu sokuqeda ukukhulelwa. Ekuqaleni, kudingeka uvakashele udokotela-sezakhi zofuzo, ozoqhuba uphenyo oludingekayo nangokunembile linqume ukuthi kunobungozi we kwezinso ingane chromosome.

Ezimweni eziningi, ukuhlaziywa zofuzo refutes ukuba khona izinkinga ingane, ngakho sokukhulelwa eningakuthwala ngokuphepha futhi ubelethe. Uma luhlolo kuqinisekisa khona Down Syndrome, abazali kufanele lenze isinqumo sabo siqu, ukugcina ukukhulelwa noma cha.

Yiziphi izinkomba kungathinta imiphumela?

Ngesikhathi sokukhulelwa IVF abesifazane ingehluka. HCG lokuhlushwa uzobe kudlulwe, kuyilapho PAPP-A uzobe lehla ngamaphesenti angaba ngu-15%, by ultrasound ingase ibonise i LZR ukwanda.

izinkinga isisindo kuthinte kakhulu ukusebenza kwama-hormone. With ukuthuthukiswa amazinga ukukhuluphala-hormone okuthiwa i luyanda kakhulu uma esisindo uphansi ngokweqile, amahomoni uzophinde zingancishiswa.

injabulo abakhulelwe elihlobene ne imizwa mayelana nokushaya khona umbungu, futhi kungathinta imiphumela. Ngakho-ke owesifazane akufanele oyi-ukumisa ngokwayo ongemuhle.

Ingabe udokotela waphikelela ngokuthi ukukhipha isisu phezu ukuthola Down Syndrome ku-fetus?

Akukho dokotela ongasenza bazophoqeleka sokuqeda ukukhulelwa. Isinqumo phambili ngokukhulelwa noma ukunqanyulwa kwaso kungamane nje ukuthatha abazali kid sika. Ngakho-ke kubalulekile ukuba ucabange kanzulu ngale ndaba futhi ukucacisa izinzuzo nezingozi kusho ukuthini ukuba nengane ene-Down syndrome.

laboratories Abaningi sikwazi ukubona isithombe ezintathu-ntathu of the ingane. Photo ultrasound Screening 1 yokuthathu ivumela abazali ukuzoqhubekisela inkumbulo ukuthuthukiswa ingane yabo eside elindelwe.
