I-Dopplerometry ekukhulelweni-kubhaliweyo

I-Dopplerometry utero-placental blood flow ebhekisela kwizo zifundo eziqhutyelwa ukuxilonga iziphazamiso zentsholongwane kwisisu, umkhumbi we-fetal, intambo ye-umbilical. Indlela esekelwe kwimpembelelo yeDoppler isekelwe kwishintsho kwixesha lokunyuka kwamagqabantshintshi avela kumzimba ohambayo. Iskrini sibamba igrafu, echazwe yinkqubo yekhompyutha.

I-dopplerometry yenziwa njani?

Naluphina ulungiso olukhethekileyo phambi kwenkqubo, ukhulelwe akufunanga. Yenziwa kwimeko efanelekileyo. I-Dopplerometry ngokwayo ayifani neyesiqhelo se-ultrasound kwaye ayibuhlungu nakanjani. Ubungakanani bendlela yokuphatha ngayo imizuzu engama-30.

Ziziphi iimpawu ezikuvumela ukuba ufake i-dopplerometry?

Ukuchonga isimo sokuhamba kwegazi, ezi zilandelayo zibonakaliso ze-doplerometry ziyazinqunywa, eziqhelekileyo zinexabiso elifanayo:

1. Umlinganiselo we-Systolic-diastolic (SDO) - esi sibonakaliso sibalwa ngokuhlula isantya se-systolic nge-diastolic.
2. Inkcazo yokuxhatshazwa (IR) ibalwa ngokuhlula umehluko phakathi kwe-systolic kunye ne-diastolic velocity ngezinga eliphezulu.
3. I-index index (PI) ifumaneka ukuba umahluko phakathi kwezinga eliphezulu kunye nobuncinci ubunqunyulwe ngumlinganiselo wokujikeleza kwegazi.

Ukuchithwa kwe-dopplerometry kwenzeka njani?

Ukutolika kwe-dopplerometry eyenziwa ngexesha lokukhulelwa kwenziwa kuphela ngugqirha. Nangona kukho imigaqo ethile, kuyimfuneko ukuba ithathe ingqalelo ekuziphatheni komntu ngamnye, kunye nombuso wayo okwangoku.

Ukuchithwa kwe-dopplerometry ye-fetal yenziwa ngokwemiqathango elandelayo:

1. IR yeemibhobho zomzimba:

• ukususela kwi-20 ukuya kwe-23 ngeveki-0,62-0,82;
• Iiveki ezingama-24-29 - 0.58-0.78;
• 30-33 iiveki - 0.521-0.75;
• Iiveki ezingama-34-37: 0.482 ukuya ku-0.71;
• Iiveki ezingama-38-40: 0.42-068.

• Ukususela kwi-iveki ye-16 ukuya kwe-19-4,55-4,67;
• Iiveki ezingama-20 ukuya ku-
• Iiveki ezingama-23-25, 3.41-3.61;
• Iiveki ezingama-26-28 - 3.191-3.27;
• Iiveki 29-31 - 2.88-2.94;
• Iiveki ezingama-32-34 - 2.48-2.52;
• Iiveki ezingama-35-37 - 2.4-2.45;
• Iiveki ezingama-38-41 - 2,19-2,22.

Iimpawu ezinikeziweyo zezibonakaliso zesigqirha se-doplerometry ziguquka ngeveki, njengoko kuboniswe ngentla.

Emva kweziphumo, ugqirha uvavanya imeko ye- flow of blood flow, kwaye wenza isigqibo malunga nemfuneko yonyango, ukuba izibonisi azihambelani nomgangatho.
