I-dopplerometry ekukhulelwe - okulotshiwe

I-Dopplerometry i-utero-placental blood flow ibhekisela kulawo masifundo aqhutshwa ukuze ahlolwe ukuphazamiseka kwe-circulatory esibelethweni, izitsha ze-fetal, intambo ye-umbilical. Indlela esekelwe umphumela we-Doppler isekelwe ekushintsheni kumvamisa wokuqhutshwa kwegagasi eliboniswa emzimbeni ohambayo. Isikrini sithatha igrafu, ehlushwa uhlelo lwekhompyutha.

I-dopplerometry yenziwa kanjani?

Noma yikuphi ukulungiselela okukhethekile ngaphambi kwenqubo, okukhulelwe akudingeki. Lenziwa ngendlela ejwayelekile. I-dopplerometry ngokwayo ayifani ne-ultrasound evamile futhi ayibuhlungu ngokuphelele. Isikhathi sokuxhaphazwa singamaminithi angu-30.

Iziphi izinkomba ezikuvumela ukuba ufake i-dopplerometry?

Ukuze unqume isimo sokugeleza kwegazi, lezi zinkomba ezilandelayo ze-doplerometry zizinqunywa, okuvame ukuba nezindinganiso ezihambisanayo:

1. I-Systolic-diastolic ratio (i-SDO) - le nkhomba ibalwa ngokuhlukanisa isilinganiso se-systolic nge-diastolic.
2. Inkomba yokuphikisa (IR) ibalwa ngokuhlukanisa umehluko phakathi kwesilinganiso se-systolic ne-diastolic ngesilinganiso esiphezulu.
3. Inkomba ye-pulsating (PI) itholakala uma umehluko phakathi kwesisindo esiphezulu nesincane esahlukaniswa yi-velocity yegazi ejwayelekile.

Ukukhishwa kwe-dopplerometry kwenziwa kanjani?

Ukuchazwa kwe-dopplerometry eyenziwa ngesikhathi sokukhulelwa kwenziwa kuphela udokotela. Naphezu kokuthi kunezimo ezithile, kubalulekile ukucabangela ukuhluka komuntu ngamunye, kanye nombuso wayo okwamanje.

Ukuchithwa kwe-dopplerometry ye-fetal kwenziwa ngokwezilinganiso ezilandelayo:

1. I-IR yemithinga yemithi:

• kusukela ngesonto eli-20 kuya kwezingama-23 - 0,62-0,82;
• Amasonto angu-24-29 - 0.58-0.78;
• 30-33 amasonto - 0.521-0.75;
• Amaviki angu 34-37: 0.482 kuya ku-0.71;
• Amaviki angu-38-40: 0.42-068.

• Kusukela ku-16 kuya ku-19 isonto - 4,55-4,67;
• Amaviki angu-20-22 - 3.87-3.95;
• Amaviki angu 23-25, 3.41-3.61;
• Amasonto angu-26-28 - 3,191-3.27;
• Amaviki angu-29-31 - 2.88-2.94;
• Amaviki angu 32-34 - 2.48-2.52;
• Amaviki 35-37 - 2.4-2.45;
• Amaviki angu-38-41 - 2,19-2,22.

Amanani anikeziwe wezinkomba zesimiso se-doplerometry ashintsha masonto onke, njengoba kuboniswe ngenhla.

Ngemuva kwemiphumela, udokotela uhlola isimo sokugeleza kwegazi, futhi wenza isinqumo ngesidingo sokwelashwa, uma izinkomba zingavumelani nokujwayelekile.
