I-Ultrasound emavikini angu-32 ukubeletha

I-Ultrasound ifakiwe kwisethi ejwayelekile yezifundo ngesikhathi sokukhulelwa. I-Ultrasound ihlelwe futhi ingenakulungiswa, ihleliwe inezinsuku zokugcina ezicacile futhi ihlola ukutholakala kwezinkinga zokuzalwa ezingenasifo nesifo sofuzo. I-ultrasound yokuqala yenziwa emavikini angu-9-11, owesibili ngo-19-23, kanti i-ultrasound yokugcina ekukhulelweni yenziwa emavikini angu 32-34.

Kungani uqhuba i-ultrasound trimester yokukhulelwa?

Uzi lwesithathu oluhleliwe ngesikhathi ukhulelwe lenzelwe izinhloso ezilandelayo:

• ukuhlola isimo esakhiwe futhi esisebenza kahle se-placenta (ukuqedwa kokuntuleka kwe-placental);
• ngenhloso yokwaziswa kwesimiso somzimba wesisu (ukukhipha ukubambezeleka kokuthuthukiswa kwe-intrauterine) nendawo yayo emgodini wesibeletho (ikhanda, i-pelvic, isiphambano);
• ukufeza i-biometrics yesisu (kulinganisa umjikelezo wekhanda, u-hip nesisu), unqume ukuvumelanisa ubukhulu be-fetal kuze kube sesikhathini sokukhulelwa.

Ingane ibheka kanjani i-ultrasound engxenyeni yesithathu yokukhulelwa?

Ku-ultrasound ye-fetus yamaviki angama-30, kubonakala ukuthi isikhumba asisekho wrinkled, kodwa bushelelezi. Isisindo somntwana ngu-1400 amagremu, futhi ukuphakama ku-40 cm.

Ngesikhathi se-ultrasound emasontweni angama-32 okubeletha, ungabona ukuthi isisindo somntwana wesisu singama-1900 amagremu, futhi ukuphakama kungu-42 cm. Ingane isivele ifana nendoda encane, inayo yonke into eyenziwe, ngesikhathi se-ultrasound ungabona ukunyakaza kwayo (isisu esidlwengula, ukuphoqa ngezimbambo nemilenze). Lapho wenza i-ultrasound ku-3D no-4D, ungabona amehlo omntwana.

Ukuhlolwa kwe-biometry ebusweni emavikini angu-32 ukubeletha:

• usayizi we-biparietal kule nkathi ulingana no-75-89 mm;
• usayizi we-frontal-occipital nge-ultrasound ungama-95-113 mm;
• umjikelezo wekhanda le-fetal ngokuvamile u-283-325 mm;
• umjikelezo wesisu somntwana ngesonto lama-32 yi-258-314 mm.

Uma kulinganisa amathambo ende, imiphumela elandelayo iyatholakala:

• ubude besifazane buyi-56-66 cm;
• Ubude be-humerus - 52-62 cm;
• ubude bamathambo esiphezulu ngu-45-53 cm;
• ubude bamathambo ama-shin buyi-52-60 cm.

Ku-ultrasound emavikini angu-33 wokukhulelwa, ungabona ukuthi isisindo somntwana senyuke ngamagremu angu-100 futhi kakade sasi-2 kg, kanti ukukhula kwaba ngu-44 cm.

Ngenxa ye-ultrasound, ungabona ukuthi ekuqaleni kwe-trimester yesithathu yokukhulelwa, ingane isivele isakhiwe ngokugcwele futhi ezinyangeni ezilandelayo iyokhula kuphela ngenkuthalo futhi ithole isisindo. Ngakho-ke, ku-trimester yesithathu, kubaluleke kakhulu ukuthi umama wesikhathi esizayo kufanele adle ngokulinganisa futhi angasebenzisi kabi ufulawa futhi amnandi.

Ukwenza i-ultrasound yesithathu ekukhuleleni kuhilela ukuqhuba i-doppler, ukuze kuhlolwe ukugeleza kwegazi emithonjeni yezintambo. Ngaphambi kokungajwayelekile, kuyadingeka ukuthi kuqhutshwe i-doplerometry yezitsha ezisele (umthambo we-cerebral middle, uterterial uterine, i-aorta ye-fetus).

I-Ultrasound ekukhulelweni kwesikhathi eside

I-ultrasound emva kwamaviki angu-34 ayihlelwe futhi iyenziwa ngokusho kwezinkomba. Uma owesifazane eqala ukubheka ukukhushulwa kwesibindi, esebenzayo noma ngisho nokuyeka ukuzwa. Esinye isibonakaliso se-ultrasound ekukhulelweni kwekwephuzile yisikhathi sokuphuma kwegazi okuvela emthonjeni wesisu (ngegazi elikhulu, lo wesifazane uboniswa ukulethwa okuphuthumayo ngesigaba sokudla). Ku-ultrasound, ungabona ubukhulu be-hematoma nokwanda kwayo okungenzeka. Uzi emasontweni angama-40 wokubeletha futhi kamuva aqhutshwa ukuze ahlolisise intambo nokuxubana komgudu.

Njengoba sibona, i-ultrasound engxenyeni yama-32 yokukhulelwa kuyisifundo esibalulekile sokuxilonga esivumela ukuxilonga ukuhlukumeza kwe-placenta ngokuhamba kwesikhathi, kanye nokuhlola ukuthuthukiswa kwe-fetus (ukusebenzisa i-biometrics) nokulandelwa kwayo ngesikhathi sokubeletha. Ku-ultrasound ku-trimester yesi-3, kuyadingeka ukwenza i-artery doppler yomzimba.
