Ukwazisa okokuqala ngunina nengane yakhe kwenzeka ngesikhathi isifundo sokuqala se-ultrasound. Isifundo ngasinye sinemisebenzi yaso futhi kufanele senziwe ngesikhathi esithile. I-ultrasound yokuqala ehleliwe ivela kweshumi kuya kwesonto leshumi nambili. Inhloso ye- ultrasound yokuqala iwukuqedwa kwezinto ezingavamile, ukucaciswa kwesikhathi sokukhulelwa kanye nokuqedwa kwezinguquko ezinzima ze-fetus.
Esifundweni sesibili se-ultrasound, esenziwa phakathi nenkathi kusukela kumashumi amabili kuya kwamashumi amabili nesithupha ngesonto, isazi sibheka isakhiwo sezinhlaka, sihlola isimiso sezinzwa esisemkhatsini kanye nemikhuba enhle yesistimu yenhliziyo. Okwamanje usuvele usunqume ubulili bomntwana.
Imigomo yesithathu ye-ultrasound ekukhulelwe ingaphansi kwemingcele yama-32-34 amasonto. Umgomo oyinhloko walolu cwaningo ukucacisa ingxenye yokwethulwa kwengane futhi ukukhipha ukubambezeleka nokukhubazeka kwengane.
Imisebenzi ye-ultrasound ehleliwe yesithathu ekukhulelwe
I-Ultrasound ye-trimester yesi-3 iyona yokugcina i- ultrasound yokuhlola , lokho kuyisibopho, esidlula umama ozayo.
Incazelo yokuhlola i-ultrasound 3 trimester izokwenza ukuthi:
- Ukunquma isimo lapho ingane ikhona khona ukuze kunqume amasu okuqhuba abasebenzi: isigaba semvelo noma se-caesarean.
- Cacisa idatha ye-fetus ye-fetus: ubukhulu, ubuningi obulindelekile, kanye nobunikazi be-data etholakalayo esikhathini sokukhulelwa. Ku-ultrasound ku-3rd trimester, kungenzeka ukuthola ukutheleleka kwe-fetus, ngenxa yezifo ezithathelwanayo ngumama uqobo, ezinye izinto ezimbi ezingazange zikhonjiswe ezikhathini zangaphambili. Futhi, ukuhlolwa kwe-ultrasound ku-trimester kungathola izinguquko ku-cortex ye-cerebral.
- Ukunquma inani le-amniotic fluid. Uma inani lama-amniotic fluid lidlula kakhulu kusuka esimweni esijwayelekile kumqondisi omkhulu noma ongaphansi, lokhu kungabonisa ushintsho kwimininingwane ye-fetus ye-fetus. Okokuqala, qaphela isisu, isisu sesisu.
- Ukuqeda izinkinga ezingenzeka, ezifana nokubonakala kwezinto ezinamandla, ukungakwazi ukusebenza komlomo wesibeletho, njll. Lokho okungavimbela ukubeletha okuzenzekelayo.
Phakathi nokuhlolwa kwe-ultrasound, ukuphefumula nokusebenza komzimba we-fetus kuhlolwe, i-placenta ihlolwe: indawo yayo nobukhulu bayo, ukutholakala kwe-inclusions ye-pathological isakhiwo sayo. Lolu cwaningo lwenza kube lula ukunquma ukukhula komntwana kanye nosuku olulindelekile lokulethwa.
Izindlela ze-ultrasound yesithathu ekukhulelwe
Ngenxa yokuziphatha kwe-ultrasound ku-3rd trimester, kunezinqubo eziqinile, ngokusho ukuthi udokotela kufanele ahlole yini owesifazane okhulelwe futhi athole imininingwane enembile ekuthuthukiseni i-fetus. Le protocol inikeza umbono ocacile kwisithifiketi ngesimo somama okhulelwe nengane yakhe yesikhathi esizayo. Le dokhumenti izosiza udokotela ngokushesha ukuphendula kunoma yiziphi izimo ezingase zenzeke ngesikhathi sokubeletha. Ngokwejwayelekile kwe-ultrasound, i-trimester kufanele ithwale ulwazi olulandelayo.
Inombolo yezithelo, isikhundla sabo. Kuhle, uma ingane yakho inenhloko ye-previa. Futhi, isiphetho se-ultrasound sinenkomba ezinjalo:
- I-BPR - isimiso sika 7,6-9,1 cm;
- I-OZH - umkhuba ka-8-10.3 cm;
- I-OG - inqubo evamile ye 8.7-10.4 cm;
- I-LZR - umkhuba we-9.9-11.7 cm;
- I-DB - inqubo ka 5.7-7.1 cm.
Uma ama-ultrasound ama-3 esenziwa (amasonto angu-32-34), isisindo somntwana kufanele sibe ngaphansi kuka-2248-2750 g. Ubukhulu be-placenta akufanele buye ngaphezu kuka-26.8-43.8 mm. I-placenta iphetha ukufuduka ekuqaleni kwe-trimester yesithathu futhi ithatha isikhundla lapho kuyoba khona ngaphambi kokubeletha. Futhi hlola izinga lokuvuthwa kwe-placenta, kusukela emavikini angu-34, kufanele kube nesiqu sesibili sokuvuthwa. Inani lama-amniotic fluid akufanele libe ngaphezu kuka-1700 ml. Amanzi amaningi noma amancane angabonisa ukutholakala kwe-pathologies ebusweni.
