Inqubo yenziwa kanjani?
Ngaphambi kwe-dopplerography ye-fetus, udokotela unquma indawo engaphansi yophenyo: izitsha ze-uteroplacental igazi flow, izitsha zobuchopho, inhliziyo, isibindi. Ngokusebenzisa umsebenzi weDoppler nokuthumela inzwa engxenyeni ngaphansi kokuhlolwa, udokotela uzothola isithombe esibukweni. I-apparatus izohlaziya le datha yedwa. Inqubo ayibuhlungu futhi iphila isikhathi esifushane - imizuzu engu-10-15.
Ingabe wonke umuntu ochazwe nge-dopplerography?
Ukulandelwa kwegazi lokugeleza kwegazi okugcizelelekile kunqunyelwe bonke abesifazane abakhulelwe ngeviki le-32 lokubeletha ingane. Uma kunesibonakaliso esikhethekile (ukungakwazi ukuguquka kwamapulangwe, ukusola kokunciphisa ukukhula kwe-intrauterine), isifundo singenziwa ngaphambi kwesikhathi esibonisiwe (amasonto angu-22-24).
I-Dopplerography nayo inqunywe ezimweni ezifana nalezi:
- ukukhulelwa okuningi;
- I-Rhesus-fetus nengxabano yomama.
Futhi, ezimweni lapho izilinganiso zomzimba ze-fetus azihambisani neminyaka yobudala, i-ultrasound ye-fetus ene-dopplerography ingabelwa ukuhlola isimo sokugeleza kwegazi.
Yimiphi imigomo etholakala ku-Doppler?
Kuphelele, kune-arteries emibili kanye ne-1 emithanjeni emgqeni we-umbilical, okunikeza i-fetus izakhi kanye ne-oxygen. Ngakho-ke, emthonjeni igazi liya emntwaneni ngqo kusuka e-placenta. Nge-vein, imikhiqizo evela ekutheni isuswe kusuka ebusweni.
Ukuze usebenze ngendlela evamile yokwehlukanisa kwegazi, ukumelana ezindongeni zomthambo kufanele kube ngaphansi. Endabeni yokunciphisa umkhumbi, ukulahlekelwa kwe-oxygen kukhula, okuthinta kabi ukuthuthukiswa kwe-intrauterine.
Yikuphi ukuphazamiseka kokugeleza kwegazi okungatholakala ukuthi kune-Doppler?
Lapho wenza i-dopplerography yemikhumbi ye-fetal, lezi zinkomba ezilandelayo ziyasungulwa:
- ukugeleza kwegazi kwevelocity,
- ukucindezela kwe-vascular,
- ukuqina kwemithambo yegazi.
Uma kuqhathaniswa nemigomo etholakalayo, ukuphazamiseka okuhlukahlukene kokugeleza kwegazi kungatholakala. Ngakho, hambisa:
- I-degree eyi-A - uma kukhona ukungasebenzi kahle ohlelweni lwegazi lwe-utero-placental, kodwa uhlelo lwe-placenta lwe-fetal lusebenza ngokujwayelekile;
- I-degree 1 B - ivuliwe uma isimiso se-fetus-placenta singaphumeleli, futhi ukugeleza kwegazi okungenawo uteroplacental akusho ukuphazanyiswa;
- 2 degree - ezimweni lapho ukuhlukumeza kutholakala ngokushesha ezinkambisweni ezimbili, kodwa akuzona ezibalulekile;
- I-3 degree - iyaphawulwa lapho ukwephulwa kwesistimu ye-fetcenta ye-fetal kubalulekile, futhi ukugeleza kwegazi kwe-uteroplacental kuphazamiseka.
Ngezinga elilodwa lokuphulwa, owesifazane okhulelwe uyabonwa kulo lonke isikhathi esisele. Ukuhlolwa kanye ne-ultrasound kwenziwa kanye ngesonto. Ngesikhathi esifanayo, uma i-CTG iqhutshwa ayizange iveze noma yikuphi ukuphulwa nokwesatshiswa kokuqhubeka nokukhulelwa, ukuzalwa kwenzeka ngesikhathi.
Ngokuhlukunyezwa okungu-3, ​​owesifazane uhlolwe odokotela nsuku zonke, futhi lapho kukhona izici ezisongelayo zokukhulelwa, isigaba se-cearean senziwa.
Ngakho-ke, i-dopplerography ye-fetus iyindlela yokucwaninga enquma ukuthi ukuphuma kwegazi kujwayelekile yini nokuthi ngabe ingane ibuhlungu kanjani kulokhu.
