Fetal dopplerometry imwe yemamwe nzira dzekudzidza nezvemamiriro emwana, chinangwa chekugadzira chimiro nekukurumidza kwekubuda kweropa mu "fetal-placenta-mother" system. Kuongorora uku kunokosha zvakanyanya, sezvo zvichiita kuti zvikwanise kuziva kuti fetoplacental inoshaya pakuderedzwa kwekuberekwa kwe fetus muchibereko. Kazhinji kazhinji, doppler inowanikwa mumutatu wechitatu wekubata, sezvo nzira yekuendesa yava kusvika. Chidzidzo chinoitwa kuburikidza nekushandisa seni inokosha yakabatanidzwa kumushandisi we ultrasound.
Pfungwa ye ultrasound ye fetus ine dopplerometry
Iyi nzira yakashandiswa kubudirira mukuita kwemaminitsi anenge makumi mana ezana remakore, iyo yakava yakakonzerwa nekuda kwekusarura kwayo, kusanzwisisa uye kuchengeteka. Chinhu chinokosha cheDoppler effect ndeyekutevera: Mazwi anonyanya kushandiswa ane majekiseni akajeka anotumirwa kumasukisi uye anoratidzwa kubva kumasero matsvuku eropa ari kufamba. Somugumisiro, ultrasound inoratidzwa ne erythrocytes inodzoserwa zvakare kune sensor, asi huwandu hwayo hwave huchishandurwa. Ukuru hwekuchinja kwakaitika panguva yakatarwa ye ultrasound, uye icharatidza kutungamira nekukurumidza kwekufamba kwemasero matsvuku eropa.
Ndeipi apo zviratidzo zve fetal dopplerometry dzinodiwa?
Rudzi urwu rwekudzidza runobatanidzwa munharaunda yokuti pane kukanganisa kunogona kuitika kwehuputi hwekutepa ropa. Vakadzi vari panjodzi vari pangozi:
- late toxicosis;
- hypertension;
- pyelonephritis;
- systemic proliferation yezvibatanidza zvigunwe;
- chirwere cheshuga mellitus;
- kukakavadzana kweamai nevana uye nezvimwe zvakadaro.
Uyewo, pane kazhinji kudiwa kwe dopplerometry yemidziyo ye fetal, kunyanya mumamiriro ezvinhu apo ultrasound inoratidzira matambudziko anotevera mukubudirira kwayo:
- kushayiswa kwekutanga kwechirwere chemukati;
- pronounced aridity ;
- hukuru hwemwana hahufananidzi nguva yekuita gestation;
- kuberekwa kusakanganiswa uye kukanganisa kwemutsipa wemwoyo;
- kukura kusina kururama kwevana pavanotakura michero yakawanda;
- kudonhedzwa kwehuropi hwomusoro mumwana;
- anokanganikwa kuvapo kwezvirwere zvechromosomal;
- kukura kusina kururama kwemubilical cord uye nezvimwe zvisina kunaka mukugadzirwa.
Ndeupi musiyano pakati pe doppler yekuteerera fetal heartbeats uye ultrasound?
Chinyanya kukosha ndeyekuti data yakakosha inowanikwa nekubatsirwa kwema-ultrasound devices inowanikwa kubva mufananidzo wakaita uye wakachena. Doppler anopa chete mufananidzo wemifananidzo. Chidzidzo chakadai "mavara" zvachose marwizi emvura mumidziyo mumhando dzakasiyana uye mavara, ayo anonyatsoenderana nekukurumidza kwekufamba kwemasero matsvuku eropa uye nzira yavo.
Tsanangudzo ye fetal doplerometry
Zvigumisiro zvekudzidza zvinokurukurwa zviri nani nachiremba, sezvo mishonga yakasiyana-siyana ye ultrasound inogona kuve yakagadzirirwa neyo pfupiso yadzo. Nyaya inowanzozivikanwa ndeyekuti:
- SDO-systolic-diastolic ratio, iyo yakagadzirirwa ariti imwe neimwe zvakasiyana uye inoreva kunaka kwekufamba kweropa mairi;
- IPC - uteroplacental movement of blood, kuratidza kuvepo kwekukundikana muhutano hwekuyerera kweropa pakati pezvikamu izvi;
- FPN - kushanduka kwepasita, kushungurudzwa muropa kunoyerera mu "baby-placenta" system.
Panewo mamwe mazita uye mabhiizo anoratidza nzvimbo yekutsvakurudza, mitemo, kukanganisa nezvimwe zvinhu.
Zvakakosha kunzwisisa kuti mitemo ye dopplerometry ye fetus ndiyo inofanirwa kupupurira kusavapo kwezvimwe zvipupuriro mukugadzirisa kuongorora. Usavhunduka kana chidzidzo chikawana kupotsa. Mishonga yemazuva ano ine "arsenal" yakakwana kuitira kugadzirisa dhigiriro rekuita.
