I-Dopplerometry ekukhulelweni

I-Doppler iyindlela yokuxilongwa ngaphambi kokubeletha, okuyinto uhlobo lwe-ultrasound. I-Dopplerometry ngesikhathi sokukhulelwa ivame ukuqhutshwa ngesikhathi esifanayo ne-ultrasound isebenzisa okunamathiselwe okufanele kumshini we-ultrasound.

I-Dopplerometry isekelwe ekucatshangeni kwemvamisa yomsindo, okushintsha lapho kuboniswa ukusakazwa kwegazi okuhambayo. I-Dopplerometry ikuvumela ukuthi unqume ijubane kanye nemvelo yokugeleza kwegazi ezitsheni zezintambo zomzimba nesisu sowesifazane, kanye ne-aorta ne-middle cerebral artery of the fetus. Ngokusekelwe emiphumeleni yalolu cwaningo, izimpawu zokungajwayelekile emsebenzini we-placenta nokugeleza kwegazi ziyasungulwa, ngenxa yokuthi ingane ayikwazi ukuthola izinto ngokuthuthukiswa kwayo okujwayelekile. I-Dopplerometry yenza kube lula ukuxilonga ukungakwazi ukusebenza kwe-fetoplacental noma hypoxia ye-fetal ngesikhathi esifanele.

I-dopplerometry yenziwa kanjani ngesikhathi sokukhulelwa?

Inqubo ye-doplerometry ingenziwa izikhathi eziningana zokukhulelwa. Akubuhlungu futhi kuphephile kumama nengane ezayo. Ingabe i-dopplerometry ekukhulelweni kanye ne-ultrasound evamile, umehluko kuphela ukuthi nge-dopplerometry, ukulinganiselwa kwegazi kulinganiselwa, okuyinto udokotela abona kuleso sikhangiso ngomfanekiso wombala.

I-dopplerometry yenziwa ngemva kwamasonto angu-23-24 wokubeletha. Okokuqala, i-dopplerometry inqunyelwe abesifazane abakhulelwe abasengozini. Lezi, okokuqala, abesifazane abane-anemia, umfutho wegazi ophakeme, igestosis, izifo zesimiso senhliziyo nemisipha, ukutholakala kwama-Rh-antibodies egazini, isifo sikashukela . Iqembu labafaka ingozi lihlanganisa abesifazane abakhulelwe abavuthiwe ngaphambi kokuvuthwa kwe-placenta, eminingi-kanye ne-malodontics, i-chromosomal pathology ye-fetus nezinye izifo.

I-parameters ye-doplerometry ekukhulelwe

Ukuchazwa kwe-dopplerometry ekukhutheni kuncishiswe ukulinganisa izinkomba ezikhethekile ezibonisa izinga lokuphazamiseka kwegazi. Njengoba ukuhlolwa okulinganiselwe kokugeleza kwegazi kunzima kakhulu, izinkomba ezihambisanayo zisetshenziselwa i-dopplerometry. Lokhu kufaka:

• I-IR - inkomba yokumelana;
• I-P yinkomba ye-pulsation;
• I-SDO - i-systolic-diastolic isilinganiso.

Izinkomba eziphezulu zikhombisa ukunyuka okunamandla ekugezeni kwegazi, kanti izinkomba eziphansi zikhombisa ukwehla kokumelana nokugeleza kwegazi. Uma i-IR ingaphezu kuka-0.773, futhi i-SDR ingaphezu kuka-4.4, lokhu kubonisa izinkinga ezingenzeka.

Umkhuba we-dopplerometry ukungabikho kokuphazamiseka esifundweni. Kodwa uma kutholakala amaphutha athile, owesifazane akufanele aphelelwe ithemba. Izindlela ze-dopplerometry ekukhulelwe zizosiza ukulungisa inkambo yokukhulelwa, ukhethe ukwelashwa okudingekayo ukuvimbela ukuwohloka kwengane.

Ngemuva kokuhlola izinkomba, izigaba ezilandelayo zokuphazamiseka kwe-circulatory ziyasungulwa:

I-1 degree:

• A - i-blood fetoplacental flow flow, igciwane legazi eliphazamisekayo liphazamiseka;
• B - ukugeleza kwegazi kwe-uteroplacental kuphazamiseka, i-placental-placental egcinwe;

I-2 degree : ukwephulwa kwezithelo kanye nezinsika, nokugeleza kwegazi okungahambisani negazi, okungafinyeleli ekushintsheni okubalulekile;

I-3 degree : okungavamile okungaqondakali ekugezeni kwegazi lokuthomathika ngenkathi kugcina noma kuphazamisa ukugeleza kwegazi e-utero-placental.

Lapho ukwenza i-dopplerometry ekukhulelwe, owesifazane uyaqiniseka ukuthi utshele udokotela oholele ekukhuleleni kwakhe, noma ngabe lolu cwaningo lwenziwa esikhungweni esifanayo sezokwelapha lapho owesifazane ebonwa khona, noma owesifazane okhulelwe uthunyelwa esikhungweni esifanele sokubeletha esinezidingo ezidingekayo.
