Ngaba ikhuselekile ukusebenzisa i-ultrasound?
Oogqirha abanikeli impendulo engabonakaliyo. Njengoko uyazi, yonke into inetyhefu kwaye yonke into yonyango - yimizuzu kuphela. Oomama abaninzi basitshela ukuba emva kokuba i-ultrasound umntwana eqala ukudibanisa, ukuziphatha ngokunyanisekileyo, njengokubonisa ukunganeliseki. Ngesinye isikhathi kwakukho imfashini ukusho ukuba i-ultrasound ithi iphula i-DNA kwaye ikhokelela ekutshintsheni ekubunjweni kwezicubu ze-fetal. Nangona kunjalo, inzululwazi iyayiphikisa le nyaniso. Okwangoku, umonakalo kwi-ultrasound kumama kunye ne-fetus ayibonakalwanga ngokusemthethweni. Kodwa ukukhishwa kwe-ultrasound kunokukhokelela kwimiphumo emibi ehambelana nokufumanisa ngokukhawuleza kwezifo ezahlukeneyo zomntwana. Mama, yiba nengqiqo, ukuba kukho ubungqina bophando, xa inzuzo ecacileyo iphakamisa intlungu engathandabuzekiyo, ungesabi. Thembela ugqirha, kungekhona "iindaba ezibuhlungu" ezichazwe ngabahlobo. Kwaye nangona izixhobo zanamhlanje zivumela ukubhaliswa komsebenzi we-embryy heart kusuka kwiiveki ezi-4 ukususela ekukhulelwe, kunye nokusebenza kwemoto ukusuka kwiiveki ezi-8, isifundo sokuqala asikhuthazwa ukuba senziwe ngaphambi kweveki ezi-10 zokukhulelwa. Kukho ishedyuli ethile, ngokuya kuthiwa ngubani oomama abathunyelwa kwi-ultrasound.
Umshini we-ultrasound usebenza njani? Ikhupha amaza omsindo ovakalayo aphezulu angenakukwazi ukuphulaphula indlebe yomntu (3.5-5MHz). Le ngqungquthela ayifumaneki i-radioactive, inokuthelekiswa nomsindo womsindo ophuma ngamahlengethwa (akuyona ingozi ukuba lesi silwanyana sibonakalisa i-ultrasound kwiyeza). Emanzini, amaza ase-ultrasonic anceda amahlengethwa anqume ubungakanani kunye nesimo sento. Kwakhona, umqondiso we-ultrasound uvumela oogqirha ukuba balinganise ubungakanani kunye nesimo somntwana. Umtsalane we-US, oboniswe kumathambo omzimba, uthumela uphawu lwempendulo, oluguqulwa lube ngumfanekiso kwiso.
I-ultrasound yokuqala
Iiveki eziyi-10-12 - ukuzimisela ixesha elifanelekileyo lokuzala, ukuhlola indlela ukukhulelwa okuqhubeka ngayo, ukuzimisela inani leembryo kunye nesakhiwo sokwakheka kwe-placenta. Kakade, ukukhulelwa okungaphuthunyanga, isisongelo sokukhulelwa kwesisu, ukukhulelwa kwe-ectopic kunye nezinye izinto ezingaqhelekanga zichongiwe.
I-second ultrasound, iiveki ezingama-20-24
Ukumisela ubungakanani kunye nomgangatho we-amniotic fluid, izinga lokuphuhliswa kwe-placenta, ukuhlolwa kwezitho zangaphakathi zentsana, ukuchongwa kweziphene zentuthuko (ukuxilongwa kobunzima bokuzalwa be-nervous system, ngokuyinhloko i-hydrocephalus). Ngeli xesha, unokumisela isondo somntwana ongakazalwa.
I-third ultrasound, iiveki ezingama-32-34
Ubunxibelelwano lobungakanani befesti ukuya kwixesha lokukhulelwa, isikhundla somntwana esiswini, ukuvavanya ukuhamba kwegazi kwi-placenta, ukuxilongwa kwezilwanyana kunye nezinye iimpawu ezibalulekileyo ofuna ukuzazi malunga nokuhanjiswa okuza kuqala ngokukhawuleza. Ukuhlolwa kwe-ultrasound kwezinye iimeko zokukhulelwa, njengomthetho, kwenziwa ngohlobo lwesigqirha soogqirha (kwiimpawu ezizodwa okanye ukucaciswa kwedatha).
I-ultra-dimensional ultrasound-3D
Ngezinye amaxesha kuthiwa yi-ultrasound-ultrasound (ububanzi besine lixesha). Umfanekiso wokuzenzekela ngexesha lophando luvumela ukuba bhetele uqwalasela ezinye izakhiwo ezinzima ukufikelela kwiingcaphephe kwiimodi eziqhelekileyo (eziqhelekileyo). Le ngcaciso ibaluleke ngokukhethekileyo ekuqaliseni iimpazamo zangaphandle zophuhliso. Kwaye ke, olu phando lunomdla ngakumbi kubazali ngokwabo. Ukuba ukuhlolwa kwe-ultrasound ye-ultrasound yengane kunzima kakhulu - iingongoma ezingaqondakaliyo kunye nemigca ayiniki umfanekiso opheleleyo. Ngomfanekiso omathathu, ungabona umntwana njengoko kunjalo. Nangona kunjalo, kufuneka kukhunjulwe ukuba ngenxa yeso sifoto ugqirha ugcizelela amandla okubonisa, ngoko ungasebenzisi kakubi le nkqubo. Iimvumba zesikrini esisesizalweni ziya kuba ngowokuqala kwi-albhamu yakhe yezithombe. Yaye uya kuthumela ukubingelela kwakhe kuqala kubazali bakhe - uya kukushukumisa nge ipeni. Ngoku siyazi ukuba kuyingozi ukwenza i-ultrasound ekukhulelweni.
