I-KTR imele usayizi we-coccyx-parietal, futhi kubalulekile ku- trimester yokuqala yokukhulelwa ukunquma ngokunembile isikhathi sokukhulelwa futhi, ngesisekelo salokhu, ukuthuthukiswa kokuthuthukiswa komntwana. Iphutha ekubekeni umkhawulo wokugcina we-KTR usuku olulodwa kuphela, ezimweni ezingavamile - izinsuku ezingu-3.
I-CTE ye-fetus ilinganiswa kanjani?
Ukukala kwe-KTP kwenziwa ngesikhathi i-ultrasound ehleliwe. Kulesi simo, isibeletho sithathwa ezindizeni ezihlukene, emva kwalokho isibonakaliso esikhulu sobude be-fetus sikhethiwe. Yiloluphawu olubhekwa njengamambala kule nkathi. Kodwa-ke, kufanele kukhunjulwe ukuthi umbungu uzokhula ngenye i-millimeter ngosuku olulandelayo.
Kungani uhlola i-CTE ye-fetus yamasonto?
I-CTF ye-embryo ivumela ukulandelela ukuthuthukiswa kwayo ngamasonto futhi ukuxilonga ukuphutha ngesikhathi. Mayelana nokuphambuka kukhulume, uma amapharamitha ajwayelekile we-KTR ye-fetus ehluke kakhulu kusuka esimweni esijwayelekile.
Emasontweni ama-10-12 i-ultrasound yokuqala ehlelwe yenziwa, lapho ukuthuthukiswa kwe-fetus kuhlolwa, umsebenzi wenhliziyo yakhe, ubulili bomntwana buzimisele. Lolu cwaningo luchaza ubude bokukhulelwa ngokulinganisa usayizi wengane ngezigidi.
Ukusebenzisa imiphumela yetafula le-CTF ye-fetus, umuntu angahlulela ngamasonto ukuthuthukiswa okujwayelekile kwengane ku-trimester yokuqala yokukhulelwa, ngoba ukulinganisa okuvamile kwamasonto okukhulelwa kuboniswa etafuleni (etafuleni).
Etafuleni elinikeziwe le-KTP lomntwana angabona ukuthi ama-indices atholakala kuphela amasonto angu-13 kuphela. Iqiniso liwukuthi ngaleso sikhathi kuya emavikini angu-13 ukuthi le datha ibonisa kakhulu. Ukulinganisa kokugcina kwe-CTF ye-fetus kungenziwa ngamasonto angu-15. Ngemuva kwamasonto angu-16, i-CTE ye-fetus ayihlolwe, ngoba ezinye izici zivela phambili.
Kunconywa ukwenza isilinganiso se-CTE ngesikhathi samasonto angu-11 kuya ku-12 - ngaphambi kwalokhu le nqubo isenziwa, ngokushesha umbuzo uzoxazululwa ngokukhona noma ukungabikho kwezinkinga ze-fetus. Futhi i-trimester yokuqala iyafaneleka ngalokhu.
Ukunquma amanani we-KTR kuyadingeka kudokotela, ngoba kunzima ukuzama ukuqonda konke ukuhlakanipha kwalesi silinganiso ngokuzimela. Omunye angakubona ngokucacile - amasonto angu-12, i-CTE ye-fetus ikhuphuka ngo-1 mm ngosuku, futhi iqala ngeviki 13 - ngo-2-2.5 mm. Lokhu kusho ukuthi ingane iqala ukukhula ngenkuthalo, njengoba zonke izinhlelo zakhe nezitho zakhiwe ngokugcwele.
Ukumisa izinkomba ze-KTR ngamasonto
Ngenkathi yamaviki ayisithupha, i-KTR yesisu iphakathi kuka-7 no-9 mm. Ngasekuqaleni kweviki 7, i-CTR ye-fetus iyanda ibe yi-10-15 mm. Emasontweni ayishumi, i-CTE ye-fetus ingama-31-39 mm. Futhi emasontweni angu-12-13, lesi sibonakaliso senyukela ku-60-80 mm.
I-CT ye-fetus emavikini angu-14 cishe ngo-86-90 mm. Futhi kakade emavikini angu-16-17, i-CTE ye-fetus ayisakwazi ukulinganisa. Lesi sibonakaliso sishintshwa ezinye, izici ezibaluleke kakhulu kulesi sigaba.
Kungani ngempela kusukela emqhele kuya komsila?
I-trimester yokuqala yokuqala yomntwana ilinganiswa kusukela emqhele kuya komsila. Ngenye indlela, kunzima ukulinganisa ngenxa yesimo sayo ngaphakathi kwesibeletho. "Uphikisiwe", uma ngingasho njalo. Yebo, nobukhulu bemilenze namanje buncane kakhulu. Ngemva kwesikhashana, uzokwenyuka kancane futhi ukulinganisa kwakhe kuzokwenzeka kusukela phezulu kuya ezithende.
Kodwa ngisho nangemva kokuba imilenze ye-pod ikhule ngokugcwele, kuyoba nzima ukulinganisa ingane ngokukhula okugcwele, ngoba imilenze iyaqhubeka igobile. Ubude obugcwele be-fetus bungatholakala kuphela ngokungeza amanani okulinganisa okulinganiselwe okwehlukile ukusuka komqhele kuya ku-coccyx, ithanga ne-shin.
Kodwa ngokuvamile odokotela abakwenzi lokhu, ukuchaza yonke into futhi ngalesi sisekelo basekela iziphetho zabo ekuthuthukiseni ingane. Imiphumela ehlanjululwa yilezi zinkomama abafuna ukuziqhayisa ngokukhula okuphelele kwengane yabo.
