Dopplerometry mukuzvitakura - kunyorwa

Dopplerometry utero-placental blood flow rinoreva izvo zvidzidzo zvinoitwa kuti zviongorore kushungurudzika kwepachiviri mumuchembera, fetal vessels, umbilical cord. Imwe nzira yakatevedzerwa neDoppler effect inobva pakushandurwa kwehuwandu hwekutsvaga kwegungu rinoratidzwa kubva kune miviri inofamba. Iyo chinyorwa chinotora grafu, iyo inotaridzirwa nekombiyuta purogiramu.

Dopplerometry inoitwa sei?

Chero ipi zvayo yakagadzirirwa kusati yaitwa, mimba haina kudiwa. Izvo zvinoitwa munzvimbo yakatarisa. Dopplerometry pachayo haisi yakasiyana neyekugara ultrasound uye haina kunyanya kusuruvara. Nguva yekushandiswa kwemaminitsi makumi matatu.

Ndezvipi zviratidzo zvinokubvumira kuisa dopplerometry?

Kuti uone hupenyu hwekuyerera kweropa, zvinotevera zvinoratidza doplerometry zvakatemwa, izvo zvinowanzove zvakakosha:

1. Systolic-diastolic ratio (SDO) - chiratidzo ichi chinorongwa nekuparadzanisa systolic chidimbu ne diastolic.
2. Nhamba yekudzivirira (IR) inoverengwa nekuparadzanisa musiyano pakati pe systolic uye diastolic velocity nehuwandu hwezinga.
3. Iko rinotenderera rondedzero (PI) inowanikwa kana musiyano pakati pehuwandu uye hudiki hunomhanya hunoparadzaniswa nehuwandu hwemvura inoyerera velocity.

Ko kududzirwa kwedopplerometry kunoitwa sei?

Tsanangudzo ye dopplerometry yakaitwa panguva yekuzvitakura inongororwa chete nachiremba. Pasinei nokuti pane dzimwe tsika, zvakakosha kufunga nezveunhu mumwe nomumwe wemuviri, pamwe chete nehurumende panguva ino.

Kuongorora kwe fetal dopplerometry kunoitwa maererano nezvinyorwa zvinotevera:

1. IR ye umbilical arteri:

• kubva pa20 kusvika kuvhiki 23 - 0,62-0,82;
• Mavhiki 24-29 - 0.58-0.78;
• 30-33 vhiki - 0.521-0.75;
• 34-37 vhiki: 0.482 kusvika ku71;
• 38-40 vhiki: 0.42-068.

• Kubva pa16 kusvika kuvhiki 19 - 4,55-4,67;
• Mavhiki makumi maviri nemaviri - 3.87-3.95;
• Vhiki 23-25, 3.41-3.61;
• Mavhiki 26-28 - 3191-3.27;
• 29-31 vhiki - 2.88-2.94;
• 32-34 vhiki - 2.48-2.52;
• 35-37 vhiki - 2.4-2.45;
• Vhiki 38-41 - 2,19-2,22.

Izvo zvakapiwa zvinoenderana nezviratidzo zvemaitiro eDoplerometry zvinoshanduka vhiki imwe neimwe, sezvaratidzwa pamusoro apa.

Pashure pemigumisiro, chiremba anoongorora mamiriro ekudengenyeka kweropa, uye anoita chisarudzo pamusoro pekudiwa kwerapi, kana zviratidzo zvisingaenderani nemirairo.
