I-ultrasound yesibili ekukhulelwe

I-ultrasound yesibili ehleliwe ekukhulelwe yenziwa emavikini angu-20-24 okukhulelwa. Isithelo salesi sizukulwane asikwazi ukubonwa ngokuphelele, ngakho udokotela ubheka izingxenye zomzimba ngamunye nezitho zomntwana. Lesi sithombe esingaphelele asivimbeli ochwepheshe onolwazi ukuba abone ukungajwayelekile ebusweni noma ukuthuthukiswa kwakhe okujwayelekile, kanye nokunquma ubulili bomntwana.

I-Ultrasound ku-trimester yesibili yokukhulelwa izonquma ukuthuthukiswa kwe-fetus, futhi ivikele izinkinga ezihlukahlukene zokukhulelwa. Udokotela ucwaninga ngokucophelela umntwana womabili kanye nesimo sesisu, okusho ukuthi indawo yesisu. Indawo ye-fruiting ihlanganisa: i-amniotic fluid, i-placenta, i-umbilical cord.

I-Fetal ultrasound ngesonto 21

Ucwaningo lwe-anatomical ngesikhathi se-ultrasound emavikini angu-20-21 lunikeza ithuba elihle lokuqinisekisa ukuthi abazali bakhula ngendlela efanele. Ku-trimester yesibili yokukhulelwa ukuthi zonke izitho zangaphakathi zengane zibonakala ekuhlolweni kwe-ultrasound. Udokotela uhlola isimo senhliziyo, isisu nezinye izitho zokukhipha ukutholakala kwempilo. Kulokhu kuncike ekuphathweni okuqhubekayo kokukhulelwa kanye nokuzalwa okuzayo kwabesifazane. Ukushaya kwenhliziyo kwengane kungu-120-140 ukushaya ngomzuzu, okucishe kube kabili ukushaya kwenhliziyo komuntu omdala. Udokotela oqaphele uzobala yonke iminwe ezandleni nasezinyaweni zomntanakho, ngoba lo mbuzo ukhathaza wonke umama, ngisho nangaphezu kwesisindo somntwana.

I-Ultrasound inganquma ukuthi i-fetus isebenze kangakanani. Kodwa-ke, phakathi ne-ultrasound, ingane ingase isesimweni sokulala noma ukulala, ngakho-ke leli phuzu alinaki kakhulu.

Izindlela ze-ultrasound emavikini angu-21 wokubeletha

I-Uziste yenza ukulinganisa ngokucophelela kwe-fetus, ukulinganisa ukujikeleza kwekhanda nesisu, kanye nobukhulu be-hip bone, kanye ne-frontal-temporal lobe.

Ubukhulu be-fetus yamaviki angu-20-21 wokubeletha:

• ngamasonto angu-21 isisindo somntwana esibelethweni sikamama sifinyelela ku-300-350 g, futhi ukuphakama kwalo ku-18-25 cm;
• ikhanda eliphakathi kwe-166-200 mm;
• usayizi wangaphambili-occipital 60-72 mm;
• umjikelezo wesisu esiswini se-fetus ngu-137 -180 mm;
• ubude bomlenze ukusuka emadolweni kuya emthonjeni (femur) 32-40 mm;
• ubude kusukela ezinyaweni kuya emadolweni (amathambo angaphansi kwamapulangwe) 29-37 mm;
• ubude bengalo kusukela ehlombe kuya eluhleni (humerus) 29-37 mm;
• ubude bengalo kusuka esihlalweni kuya kwesigqoko (osengaphambili amathambo) ngu-24-32 mm.

Ngenxa yalezi zibonakaliso, udokotela uqinisekisa isikhathi sokukhulelwa. Iphutha ngesikhathi sokufika kwe-ultrasound emavikini angu-20-21 wokukhulelwa kungaba izinsuku ezingu-7.

Ama-Mummies akufanele asabeke kusengaphambili, ngoba ingane ngayinye ine-genetic heredity, isisindo nobukhulu bezingane zinye yobudala be-fetal, noma yi-little, buhlukile komunye nomunye.

I-Ultrasound ye-fetus nomlomo wesibeletho

I-amniotic fluid ivikela umntwana kusuka emanzini. Kanti futhi, bavumela ukufinyelela okungenakulinganiswa kwezakhi zomntwana kanye ne-oxygen ngokusebenzisa intambo yomlomo. Ukutadisha i-amniotic fluid phakathi ne-ultrasound kungase kubonise nokuthi i-pathology noma ukungabi khona kwayo. Ku-amniotic fluid, inani labo kanye nekhwalithi zifundwa. Lapho kukhona ukwehlukana okuvela emigomeni ye-ultrasound, udokotela uzohlinzekela ukuhlolwa nokwelashwa okwengeziwe.

Ukutadisha i-placenta kwenzeka ezinkomba ezimbili - indawo yayo nesakhiwo. Indawo ye-placenta ihlukile:

• Ngaphambili, uma kufakwe emdongeni wangaphakathi wesibeletho;
• Emuva, ngokulandelanayo, uma ifakwe kudonga olungemuva;
• kanye ne-previa, okubhekwa njengengozi kakhulu.

Ngesikhathi isethulo se-placenta sibheka umlomo wesibeletho. Kulokhu, lo wesifazane unconywa ukuba ahambe kancane ngangokunokwenzeka, futhi akhansele konke ukuhamba okuhleliwe ukuze agcine ukukhulelwa. Uma i-placenta ikhula, kunamathuba aphezulu okutheleleka kwe-intrauterine, okudinga ukuhlolisiswa ngokugcwele kowesifazane okhulelwe.

Ngesikhathi se-ultrasound emavikini angu-20-21 ekubelethweni, udokotela uphinde ahlole intambo yomzimba ehlanganisa umama nengane. Esikhathini sesibili sesibili sokukhulelwa, umntwana angasongwa ngendwangu yomzimba. Lokhu akukhulumi nge-pathology. Ngenxa yokuhamba okuphezulu kwengane, ingasheshe ishicilelwe, njengoba ixhunyiwe. Kodwa-ke, intambo yensimu yomzimba ngesikhathi se-ultrasound yesibili ngesikhathi sokukhulelwa yinkomba ye-ultrasound yesithathu, eyenziwa ngaphambi nje kokuzalwa.

I-cervix kufanele ivalwe ngokuqinile ngesikhathi sonke sokukhulelwa. Umsebenzi we-ultrasound ukucacisa ukuthi kukhona yini izinguquko eziyingozi kuwo. Uma umlomo wesibeletho unesivalo esincane se-pharynx yangaphakathi, kunamathuba aphezulu okuzalwa ngaphambi kwesikhathi. Udokotela owenza i-ultrasound uzothumela ngokushesha lo wesifazane kudokotela.

I-ultrasound yesibili ngesikhathi sokukhulelwa kuyovumela owesifazane okhulelwe ukuba agweme izinkinga ezingadingekile, futhi akhiphe ukungabaza okuningi ngempilo encane
