Doppler kana, zvinongova nyore, doppler pakuberekwa - iyi ndeimwe yenzira dze ultrasound. Inoshandiswa mumamiriro ezvinhu apo zvakakosha kuongorora zvakajeka ukama huri pakati peamai nemwana kuburikidza nekudzidza kwepascental circulation. Kunyanya kukosha, iyi nzira yekuongororwa ine, kana mukadzi ane chirwere chekudzivirira. Pamusana peDoplerography, zvinogoneka kunyatsotsanangura nzvimbo yemumwe mudziyo uye kusarudza kuwanda kwekufamba kweropa pamwe chete nayo.
Chisingatauriki pamwe dopplerography yevakadzi vane pamuviri ndeyekuchengetedzwa kwayo uye pamusoro pehuwandu hwehupenyu. Ichi chidzidzo chinoratidzika kunyange mumatanho ekutanga, izvo zvinoita kuti zvive zvakakosha mumatambudziko ekuongororwa kwemaininatal. Semuenzaniso, pamasvondo mashanu kusvika ku6 nekubatsira kwe doppler ultrasound kunogona kuyera kuteerera kweropa mumaketheni emuviri. Izvi zvinoita kuti zvive nyore kuziva mberi kwezvinetso zvemangwana, somuenzaniso, pamusoro pekugona kunonoka pakukura kwe fetal.
Ndeipi nguva yekuita doppler panguva yekuzvitakura?
Yokutanga ultrasound ine doppler inobatsira kuitwa panguva yekubva kuma20 kusvika kuma24 vhiki. Izvi zvakabatana nechikonzero chokuti panguva ino iyo hemostasis zvinetso zvinowanikwa mumukadzi ane pamuviri, uyewo pangozi yekukura kwe hypoxia, gestosis, intrauterine kukurumidza kukura uye kukura kwe fetus iri yakakwirira.
Kudzokorora kuongorora doppler kuvakadzi vane pamuviri kunowanzoitwa panguva ye30 kusvika ku 34 vhiki. Panguva ino, doplerography inobatsira mukuongorora kwakaoma kwekukura nekukura kwemwana.
Zviratidzo zvakananga zvekunyorwa kwevakadzi vanozvitakura
Kuwedzera pane zvinowanzoitwa Doppler tsvakurudzo, iwe unogona kunge uchida kuwedzera imwe nzira yeDoppler ultrasound sezvinorayirwa nachiremba. Izvi zvinodikanwa kana uine matambudziko ehutano kana zviratidzo zvakasiyana, zvakadai se:
- chirwere chesso, chirwere cheshuga, hypertension;
- kushungurudzika mumutambo we hemostasis;
- gestosis;
- Rhesus-kukakavara pakati peamai nemwana;
- multiple pregnancies;
- kuvapo kwehutachiwana mumatambudziko akare;
- kusapindira muhukuru hwe fetus uye nguva yekuzvitakura.
Dopplerography yekuzvitakura nekuputsika kwepasitiki
Pakupedzisira, nzira yeparcenta yakashandiswa kuongorora nzvimbo yepentecenta uye kukurudzirwa, icho chinonyanya kukosha kwekuongorora kwechibereki chekuziva nzvimbo yepentecenta mairi. Iyi nzira yaifungidzirwa kuwedzera kunyanya kuenzaniswa nekutsvakurudza kwemafirimu. Zvisinei, ikozvino nzira iyi inenge yakatsanangurirwa zvachose ne ultrasound nzira dzeparcenta tsvakurudzo.
Ultrasound ye placenta inoitwa kwete kungoziva kuti inzvimbo ipi, asiwo kugadzirisa kuongororwa (kana kuparadzwa kwayo) kwekukurumidza kuparara kwepasitiki. Zvinosuruvarisa, izvi zvinoshamisa zvinowanzoitika, kunyange zvisingaiti, pakati pevakadzi vane pamuviri.
Inenge 3 muzana yevakadzi iyo nguva yekuzvitakura yakaoma nekuputsika kwepabonde. Kukanganisa kwakadaro kwedzidziso yekuzvitora kunoitika nekuda kwesarudzo isina kukodzera yemidziyo yeropa mumatenta kana muchibereko. Kutsvaga chirwere chinogona kuita zvinhu zvakadai sechirwere cheshuga,
Zviratidzo zvemasvingo epascenta zvinogona kunge zvichionekwa kubva kumadzimai, kurwadziwa kwakanyanya mumimba pasi. Iyo nzira inogona kuendeswa ne-intrauterine kubuda ropa uye kuputsa kwekuwedzera kweprauterine yenguva yemberi yemwana. Dzimwe nguva mamiriro acho anotungamirira kurufu rwake.
Dopplerometry nemusasa inoratidzira kukanganisa kwakasimba mumoyo rhythm we fetus. Chidzidzo chinoita kuti zvive nyore kugona kunyatsoita kuti nzira yacho yaenda sei uye chii chinotyisidzira mwana. Kubva pane chidzidzo ichi, chisarudzo chinoitwa pakurapwa kwekukurumidza.
