Amasonto 20 ultrasound: evamile, isithombe

Ultrasound yindlela esimanjemanje kakhulu ukunquma kwezinso ku -fetus nezinkinga nengane esindayo. Emavikini 20 ultrasound uqhutshwa ukuhlaziya izitho ezibalulekile kakhulu fetus ukubona kombungu. Uma isikhathi akadaluli izinkinga kungenzeka, isisu ngemva kwamasonto 21 yayiyobizwa contraindicated.

Ukuthuthukiswa kwe-umbungu by ultrasound (amasonto 20): kuyinsakavukela

Ngenyanga yesithupha sokukhulelwa kumaka ukuthuthukiswa esebenzayo kwezitho fetus, kakhulu uye wakwenza ngokuzimisela athuthukile uhlelo zokuzala kanye isikhumba. Futhi:

• fetus kwakhiwa iziqalo molars;
• usunayo i isikhumba ezine-ungqimba ngokugcwele olusebenza;
• okunamafutha Ongama izicubu yakheke ngokugcwele;
• Kuvuselela inqubo izinwele zikhula zibheke ngakhona nezinzipho;
• isikhumba ukushwabana kakhulu, embozwe ukuphila kube mnandi kuphela zokuzivikela, ungqimba thickest nokuphakamisa amashiya;
• fetus surface body embozwe fluff, okuthiwa "lanugo"; Umsebenzi Its ukwenza kungenzeka vernix kuvikelwe kuya epidermis;
• ekupheleni ukwakheka kobuchopho, liye ezimazombezombe isakhiwo convolutions;
• amehlo kwengane ziqala ukuba kancane wavula, wayengase batshekule umzanyana noma umunwe oncelayo;
• uhlelo ingane sokuzivikela isivele kwakhiwa;
• kwengane isikhathi okwakhayo womsebenzi, kungaba ukuhlukanisa phakathi nesikhathi sosuku, kuncike kule ukuzola noma ujabule, ingane ngomsebenzi kungathinta ezishukumisa ethintekayo noma sokuzwa;
• Kumiswa uhlelo zokuzala umbungu is: abafana amasende ozakwehlela scrotum, US amantombazane uma sebehlanganisa amasonto angu-20 ibonisa degree of ukuvuthwa ezikhiqiza amaqanda.

Ultrasound uma sebehlanganisa amasonto angu-20 kuphela odliwa luhlolo ezibaluleke kakhulu kwabesifazane abakhulelwe, njengoba ikuvumela ukuba ahlaziye ngokugcwele ukuthuthukiswa umbungu futhi isimo sikamama.

Yini imingcele kuphenyisiswe emasontweni 20

Ngamunye Ukuhlolwa ultrasound has injongo yawo. Phakathi ultrasound (amasonto 20) Kwenziwa nesilinganiso amathambo fetus sihlaziye degree ukuthuthukiswa lonke zomzimba. Izinto ezibaluleke kakhulu yilezi:

• BDP - (biparietal usayizi skull) kukalwa phakathi sokunene nesobunxele amathambo parietal Yekhanda;
• LZR - ibanga kusuka esiphongweni ukuze ithambo occipital Yekhanda;
• MDCh - ubukhulu kwesifuba;
• SDZH - ububanzi esiswini;
• ethangeni ithambo obuphelele;
• ukushuba umzanyana , nabanye.

Ngaphezu kwalezi amatshe, ukunakekelwa okukhethekile ikhokhelwa ukushaya kwenhliziyo (kumele abe phakathi 130-160 amabhithi / iminithi) kanye nosayizi inhliziyo (18-20 mm). Iphinde ihlola khona kwamakamelo ezine inhliziyo futhi ngodonga phakathi kwazo.

kuyinsakavukela

On US (amasonto 20) ubulili wengane kungenziwa ukucaciswa ngokuqondile. Ukuze ngesandla ahlaziye imiphumela, ungasebenzisa etafuleni.

Okubalulekile! Leli thebula akusona isizathu iziphetho ngaphambi kwesikhathi, kahle wokufunda US can udokotela kuphela.

Ukulungiselela futhi ubambe ultrasound

Emavikini 20 ultrasound engenziwa ngaphandle ukuqeqeshwa okukhethekile. Abakhulelwe akudingeki unamathele ekudleni kwakho bese ulinda ukugcwaliswa lwesinye.

US ebambe indlela transabdominal kusekelwe (inzwa isendaweni udonga phambi esiswini). Uma kwenziwe uma sebehlanganisa amasonto angu-20 ultrasound Uphenyo lwesitho sangasese sowesifazane, kukhona kungenzeka kwesisu ekuseni.

Ukukhulelwa kungaba oyakulala ngazo ngohlangothi lwakho ngakwesokunxele noma emuva. Ukuze igagasi ultrasonic ukungena esibelethweni esiswini ku-ijeli ekhethekile lisetshenziswa isizinda lapho ifakwa emanzini. Yena kalula aqedwa evamile izicubu paper futhi engalethi ngokuphazamiseka.

ngesingeniso somgomo ultrasound

Ukugcwalisa idatha mayelana izithelo, isimo amniotic fluid kanye placenta wenziwa ku uphrothokholi ecacile:

1. Ikhomba inani fetus.
2. Elilinganiswayo isethulo kwengane, kubonisa okuyinto ingxenye yomzimba iseduze ukuba uphume esibelethweni. Inketho engcono kakhulu isethulo cephalic, kungenzeka isethulo fetus endaweni okhalo. Ultrasound (amasonto 20) ivumela noma iyiphi ilungiselelo izithelo, kodwa ngeviki 30 kumele uhlaliseke ukuze ingane izalwe, ngaphandle kwesithiyo futhi ngaphandle izinkinga.
3. Ikhombisa khona noma ukungabi khona intambo singabanjwa.
4. Lichaza isimo ngaphakathi kwesibeletho (myometrium), ezingase zithinte kungenzeka nokwahlulelwa.
5. Elilinganiswayo isimo zenani amniotic fluid, wabonisa khona ukumiswa low- noma polyhydramnios, (eside enjalo kunoma iyiphi ndaba particulate kwi-amniotic fluid ukuphi zokugula).
6. Icacisa ubude wesibeletho. On ultrasound (amasonto 20), kuyinsakavukela lokhu Inkomba akuyona esingaphansi 3 cm.
7. Lichaza isimo os zangaphakathi nezangaphandle. Kule nkathi kumele ivalwe.
8. Balinganisa njengoba isimo placenta. Kufanele ibekwe cishe ayisikhombisa amayintshi ukusuka os yangaphakathi. Noma yimuphi umonakalo kudinga esibhedlela esiphuthumayo abakhulelwe.

Lokhu kuhlaziya enemininingwane zisenza sikwazi ukubona wonke isithombe isimo fetus ukuvimbela kwesisu kwesikhathi.

Izakhiwo yesibili Ukuhlolwa kokubeletha

Ngokuvamile, ingane ultrasound 20 ngesonto ezenzeka kanye nokubusisa Doppler cwaningo. Lokhu kwenza kube nokwenzeka ukubona khona chromosomal noma kwezinso zofuzo umbungu noma ukuqinisekisa ukuthi ingane enempilo ngokuphelele.

Doppler kuthola khona izinto ezithile egazini, okuqukethwe kwabo. Hlaziya umbono ophelele futhi sifinyelele eziphethweni ngesimo umbungu can kuphela udokotela udokotela-zofuzo.

Emavikini 20 ultrasound izifundo ephephile futhi ulwazi ezibonisa isimo jikelele we-fetus kanye nezinga nokuthuthukiswa kwazo zonke izitho ezibalulekile.

Sexing

Emavikini 20 ultrasound ongabonisa ngokunembile ucansi ingane. Kulula ukunquma. Ngo abafana, isibunu abonakala ngesikhathi esisodwa, kanye namantombazane angekho iyiphi convexity.

Kunzima ukunquma ocansini singenzeka ngenxa isikhundla fetus. Kulokhu kungenzeka ukuba afeze cwaningo eyalandela ngemva kwemizuzu engu-15. Abesifazane abakhulelwe bayacetshiswa ukudla ushokoledi kancane ukuba abe encane asebenzayo.

Lapho umntwana esiswini sakhe, futhi kunzima ukunquma ocansini yayo. Ezinye izingane phakathi ultrasound jikisa noma ukufihla, ngoba ucansi wengane abazali kuseyimpicabadala waze wabeletha.

Ngisho usebenzisa yesimanje imishini ultrasound amaphutha kungenzeka kusukela definition phansi, lena kufanele kube ngomumo.

ikhulelwe

Kuleli toxicosis eside bese sivele sidlulile, kodwa ukhulelwe kungaphumela ngokuvamile nomuzwa osindwayo esiswini noma isilungulela. imiphumela Common ukugula umlenze amajaqamba nekhanda. Ukunciphisa lokhu umuzwa, kudingeka ukhululeke ngokuphelele, udle, uphuze isamba elanele amavithamini.

Kubalulekile ukulandela isimo ukuvuvukala kanye khulula. Uma ukuvuvukala kubangela ukungakhululeki, kuzomele uxhumane nodokotela wakho. Uma ushintsha ubuningi noma isimo sokukhishwa futhi kufanele ngokushesha uthintane udokotela wezifo zabesifazane ukuze ingangenwa amagciwane umbungu.

Nge-ultrasound (amasonto 20) isithombe fetus kungaba basindiswe futhi ibekwe ku-albhamu yomndeni. Lesi sithombe uzonikhumbuza elimangalisayo isikhathi encane.

Ucwaningo emasontweni 20 - iyona ukuhlaziywa ebaluleke kakhulu isimo umbungu, ngakho musa ukudonsa nokunganakwa. Uma kungenjalo, noma iziphi izici ekuthuthukisweni noma ngeziphambeko ayikwazi ukutholwa ngesikhathi esifanele.
