Ukuhlola ukuhlolwa kwamakhosikazi akhulelwe kwenziwa ukuze kutholakale ngesikhathi esithile ukuphutha okuvela esimweni esivamile ekuthuthukiseni i-fetus futhi kuthathe izinyathelo ezifike ngesikhathi. Ukuhlolwa kokuhlolwa kwe-Ultrasound kufanele kwenziwe izikhathi ezingu-3 ngesikhathi esibekiwe. Ukuhlolwa kokuqala kwe-ultrasound kwenziwa kusukela emavikini angu-11 nosuku olulodwa kuya emavikini angu-14. Kulo mkhakha, hlola ukuthi kunezibonakaliso zokungafani kahle kwezakhi zofuzo (izibonakaliso ze-Down's syndrome, izinkinga ezinkulu zobuchopho nomgogodla, ukutholakala kwamalungu), okungavamile ngesikhathi sokukhulelwa ngokwaso (i-hematoma, ukuphazamiseka kwamapayipi, isongo sokukhulelwa kwesisu).
Ukuhlolwa kwe-ultrasound yesibili ngesikhathi sokukhulelwa kwenziwa ngesikhathi sokuphela kwamasonto angu-18 nosuku olulodwa kuze kube sekupheleni kwamasonto angama-21, phakathi nalesi sikhathi, inhliziyo ye-fetal ihlolwe ngenxa yokungabi namaphutha, wonke amathambo we-tubular wezitho, izandla nezinyawo ahlolwe, ukutholakala kwesisu, isisu, isakhiwo sobuchopho, ubukhulu be-cerebellum kanye ne-ventricles yobuchopho, ukuxhumana kokuthuthukiswa kokukhulelwa ngokwezintambo, kubonisa ukwehluleka okungabonakali ekuhlolweni kokuqala).
Uma ukungavumelani okungahambisani nokuphila kwe-fetus kuboniswe ekuhlolweni kokuqala noma kwesibili, owesifazane angase anconywe ukuba aqede ukukhulelwa ngezizathu zezokwelapha (emva kwalesi sikhathi, ukukhulelwa akukwazi ukuphazanyiswa). Uma kukhona ukwephulwa kokuthuthukiswa kwe-fetus noma ukuphambuka kusuka kwendabuko, ngokusho kwezinkomba, ukwelashwa nokuphathwa kwesiguli ngezikhathi zokukhulelwa ezilandelayo kunqunywe.
I-ultrasound yokuhlola yesithathu yenziwa emasontweni angu-31-33, phakathi nalesi sikhathi, isethulo sesisu, ukuvuthwa kokukhulelwa, isimo se-placenta, ukubona zonke izinkinga ezingase zenzeke ngesikhathi sokubeletha nokubeka ukwelashwa okufanelekile ngokusho kwezinkomba.
Imingcele ye-Ultrasound emavikini angu-20
Nakuba ukuhlolwa kwesibili kwe-ultrasound kuqhutshwa ngamaviki angu-18-21, kodwa ngokuvamile kaningi owesifazane okhulelwe uthunyelwa ku-ultrasound emavikini angu-20 wokukhulelwa. Ngokuvamile, imingcele iguquguquka phakathi kwamasonto angu-1-2, kodwa izinkomba eziningi ezijwayelekile zithatha isikhathi sokukhulelwa yi-ultrasound. Izinkomba ezibalulekile zokunquma isikhathi:
- usayizi we-biparietal we-skull (i-BPR) - phakathi kwamathambo e-parietal we-skull - ngakwesokudla nangaphakathi kwangakwesokunxele nangemuva;
- ubude besifazane;
- ububanzi obukhulu besifuba (SDHC); kusho ububanzi besisu (SJ);
- usayizi we-frontal-occipital cranial (LZR);
- ubukhulu be-placenta neminye imingcele.
- I-Ultrasound emavikini angu-18-19 wokukhulelwa kunamazinga alandelayo: BPR 41.8-44.8 mm, LZR 51-55 mm, ubude besifazane 23,1-27,9 mm, SDH 37,5-40,2 mm, SJ 43 , 2-45,6 mm, ubukhulu be-placenta 26,2-25,1 mm, inani lama-amniotic fluid 30-70 mm (kuze kube sekupheleni kokukhulelwa).
- I-ultrasound emavikini angu-19-20 okukhulelwa : i-BPR 44.8-48.4 mm, i-LZR 55-60 mm, ubude besifazane ubude buka 27.9-33.1 mm, i-SDHC 40.2-43.2 mm, i-SDJ 45.6- 49,3 mm, ubukhulu be-placenta 25,1-25,6 mm.
- I-Ultrasound evikini le-20-21 lokukhulelwa - imingcele evamile: i-BPR 48,4-56,1 mm, i-LZR 60-64 mm, ubude besifazane 33,1-35,3 mm, i-SDHC 43,2-46,4 mm, i-SJ 49 , 3-52.5 mm, ubukhulu be-placenta 25.6-25.8 mm.
Ngaphezu kwalokho, nge-ultrasound emavikini angu-20, izinga lokushaya kwenhliziyo le-fetus (isilinganiso senhliziyo) kusuka ku-130 kuya ku-160 ukushaya ngomzuzu, isigqi. Ubukhulu benhliziyo kwi-ultrasound emavikini angu-20 wokukhulelwa buyi-18-20 mm, kuyilapho kudingekile ukuhlola ukuba khona kwawo wonke amakamelo angu-4 enhliziyo, ukufaneleka kwezitsha eziyinhloko, ukutholakala kwamagundane enhliziyo, ukungabi khona kweziphambeko ezisezintabeni zentuthuko nokunye.
Kungenxa yokuhlolisisa inhliziyo ukuthi i-ultrasound of the fetus ihloswe emavikini angu-20: phambi kwezinto ezingavumelani, kunconywa ukuqeda ukukhulelwa ngezizathu zezokwelapha. Futhi uma lezi zinkohlakalo zingase zisebenze ezinsukwini zokuqala zokuphila kwengane futhi ziqinisekise ukuthi ikusasa lakhe lizokwazi ukusebenza, owesifazane okhulelwe uyathunyelwa kusengaphambili ezindaweni ezizokwelapha zokwethula kanye nokungenelela okuhlinzekwa okulandelayo enhliziyweni yengane.
