Ingabe kuphephile ukusebenzisa i-ultrasound?
Odokotela abanikeli impendulo engavamile. Njengoba wazi, konke kunobuthi futhi konke kungumuthi - kungumthamo kuphela. Omama abaningi basitshela ukuthi emva kwe-ultrasound ingane iqala ukujoyina, ukuziphatha ngokwengeziwe, njengokungathi ukubonisa ukunganeliseki. Ngesinye isikhathi kwakungokwemvelo ukusho ukuthi i-ultrasound ithi iphula i-DNA futhi ibangela izinguquko ekubunjweni kwezicubu zesisu. Noma kunjalo, isayensi iphikisana nalokhu iqiniso. Okwamanje, umonakalo we-ultrasound kumama ne-fetus awubonakalisiwe ngokomthetho. Kodwa ukwenqatshwa kwe-ultrasound kungaholela emiphumeleni enzima ehambisana nokutholakala kwamuva kwezinto ezihlukahlukene ze-fetus. Mama, yiba nengqondo, uma kukhona ubufakazi bokucwaninga, uma inzuzo ecacile ingaphezu kokulimala okungabaza, ungesabi. Thembela udokotela, hhayi "izindaba ezesabekayo" abangani abatshelayo. Futhi nakuba imishini yesimanje ivumela ukubhaliswa komzimba womzimba kusuka emasontweni angu-4 kusukela ekukhulelwe, kanye nokusebenza kwemoto kusuka emavikini angu-8, isifundo sokuqala asikhuthazwa ukuba senziwe ngaphambi kwamasonto ayishumi okukhulelwa. Kukhona isimiso esithile, ngokusho ukuthi omama abazayo bayothunyelwa ku-ultrasound.
Umshini we-ultrasound usebenza kanjani? Iveza amagagasi omsindo wemvamisa ephezulu engenakuthola indlebe yomuntu (3.5-5MHz). Le mvuthwandaba ayiyona imishanguzo ye-radioactive, ifaniswa nomswakama ozwakalayo owakhulunywa ngamahlengethwa (akuyona ingozi ukuthi lesi silwane sibonakalisa i-ultrasound emithi). Emanzini, amagagasi e-ultrasonic asiza amahlengethwa anqume ubukhulu nesimo sento. Futhi, isignali ye-ultrasound ivumela odokotela ukuba balinganise ubukhulu nesimo se-fetus. I-wave-US, eboniswa ngamathishu omzimba, ithumela isignali yempendulo, eguqulwa ibe isithombe kumqapha.
I-ultrasound yokuqala
Amaviki 10-12 - ukuzimisela isikhathi esiqondile sokubeletha, ukuhlola ukuthi ukukhulelwa kuqhubeka kanjani, ukuzimisela inani lemibungu kanye nokwakhiwa kwe-placenta ukwakheka. Kakade, ukukhulelwa okungathuthukisiwe, isongo sokukhulelwa kwesisu, ukukhulelwa kwe-ectopic nezinye izinto ezingavamile.
I-ultrasound yesibili, amasonto angu-20-24
Ukunqunywa kobuningi kanye nekhwalithi ye-amniotic fluid, izinga lokuthuthukiswa kwe-placenta, ukuhlolwa kwezitho zangaphakathi zengane, ukuhlonza ukukhubazeka okuthuthukiswayo (ukuxilongwa kwezinkinga zokuzalwa ezingekho ohlelweni lwesimiso esiyinhloko, ngokuyinhloko i-hydrocephalus). Ngalesi sikhathi, ungakwazi ukunquma ubulili bomntwana ongakazalwa.
I-ultrasound yesithathu, amasonto angu-32-34
Ukuxhumana kwezinga lesisu lokubeletha, isikhundla somntwana esibelethweni, ukuhlolwa kokugeleza kwegazi ku-placenta, ukuxilongwa kwe-pathologies nezinye izici ezibalulekile okudingeka wazi ngazo ngokulethwa okuzoqala maduzane. Ukuhlolwa kwe-ultrasound kwamanye amagama okukhulelwa, njengombuso, kwenziwa ngokusho komuthi kadokotela (ngokubonisa izinkomba ezikhethekile noma ukucaciswa kwedatha).
I-ultra-dimensional ultrasound - i-3D
Ngezinye izikhathi kuthiwa yi-ultrasoundal ultrasound (ubukhulu besine yisikhathi). Isithombe sokuziphendulela phakathi nalolu cwaningo sivumela ukuthi sicabange kangcono izakhiwo ezithile ezilukhuni ukuzitholela ucwaningo kumodi ejwayelekile (evamile). Lolu lwazi luwusizo ngokukhethekile ekunqumeni ukukhubazeka kwangaphandle kokuthuthukiswa. Futhi-ke, lolu cwaningo luyathandeka kakhulu kubazali ngokwabo. Uma ukuhlolwa kokujwayelekile kwe-ultrasound ultrasound kwengane kunzima kakhulu - amaphuzu angaqondakali nemigqa anganiki isithombe esiphelele. Ngesithombe esilandelayo, ungabona ingane njengoba ikhona ngempela. Noma kunjalo, kufanele kukhunjulwe ukuthi ngokuzithombe okunjalo udokotela uqinisa amandla esignali, ngakho ungasebenzisi kabi le nqubo. Izithombe zomvuthwandaba esibelethweni ziyoba ngowokuqala ku-albhamu yakhe yezithombe. Futhi uzothumela izibingelelo zokuqala kubazali bakhe - uzokuzulisa nge ipeni. Manje siyazi ukuthi kuyingozi yini ukwenza i-ultrasound ekukhulelwe.
