Chii chakakosha kuitisa ultrasound-doppler?
Iko rudzi rwekudzidzira rinokubvumira kuziva chirwere chinotungamirira kunonoka mukukura kwe fetal ye fetus. Penguva yekuongorora, chiremba anosimbisa hutachiona hwehutachiona hwemvura. Izvi zvinoitwa nekuongorora chiedza chemidziyo yeropa yakananga mumutsara wembilical pachayo.
Panguva imwecheteyo, chiremba anogadzirisa nguva uye nhamba yepfungwa mukati mechecheche, iyo inobvumira munhu kugumisa nezvehupenyu hwake hwose.
Ndeapi marudzi e dopplerometry aripo?
Sezvo wataura nezvenyaya iyi kuti iri doppler uye izvo zvinoda madzimai ane pamuviri, zvinofanira kuonekwa kuti pane 2 maitiro emhando iyi yekuongororwa: duplex uye triplex.
Nekubatsirwa kwechiremba wokutanga anowana ruzivo rwakavimbika zvakananga pamusoro pemudziyo pachako, iyo ndiyo nyaya yekudzidza. Nekubatsira kwetatu regimen, nyanzvi inotsanangura kuzadza kweropa ne oksijeni. Pamusoro payo, tinogona kugumisa kana muviri uye oksijeni zvakakwana kugamuchira chibereko uye kana hypoxia inobata .
Izvo uye pamhedziso ipi inonzi doppler panguva yekuzvitakura?
Chokutanga pane zvose, zvinofanirwa kutaurirwa kuti, maererano nemamiriro ayo uye sargorithm, chidzidzo ichi hachisi chakasiyana neye ultrasound. Ndicho chikonzero vamwe vanaamai vangave vasingazivi zvavakaita doppler, kana izvi zvisati zvamboziviswa.
Kana iwe uchitaura zvakananga pamusoro pekuti doppler yakaitwa sei panguva yekuzvitakura, kuongorora kunotanga nekuti mukadzi ane pamuviri avete pamubhedha mune chinzvimbo chepamusoro. Zvadaro chiremba anobvunza kunyatsobudisa pachena dumbu uye zvishoma kuderedza jira kana tambo. Pamusoro peganda remuviri, gel inokosha inoshandiswa, iyo inofambisa inonzi ultrasonic pulse uye inovandudza kusangana kweropa pamwe neganda.
Kufambisa sensor pamusoro pechiso chechiremba, chiremba anoongorora huwandu hwekuvandudza fetus, kugadzirisa ukuru hwahwo, nzvimbo munzvimbo yechibereko, i.e. chinhu chakafanana neye uye ultrasound.
Zvadaro vanotanga kuongorora uye kuongorora midziyo yepascental blood flow. Pakuguma kwegadziriro iyi, amai vakamirira vanodzima gel rinoramba riri mudumbu uye rinomuka kubva pamubhedha.
Sezvaunoziva, mimba yese inenge ine maitiro ake. Nokuti chirongwa chezviito uye zviongorori chiremba anoita nekambani yavo. Zvisinei, zvakakodzera kuti titaure kuti doppler ultrasound ndiyo inomiridzirwa inyanzvi yekutsvakurudza zvinhu, iyo inofanirwa kuitwa kaviri kuitira nguva yose yekuita. Kazhinji, iyi nzira inoitwa panguva ye 22-24 nevhiki 30-34.
Ndezvipi zviitiko zvinokwanisika kuitisa kumwe kuongorora?
Mune mamiriro ezvinhu apo fetus inotanga nekukurumidza kubva panguva iyo, kana apo pakanga pasina zvirwere zvisingagumi mukati mevakadzi vane pamuviri vasati vaita gumbo, imwezve ye-ultrasound-doppler inogona kurongerwa.
Kana kutaura zvakananga maererano nezviratidzo zvekushandiswa kweiyo nzira, zvinokosha kutumidza zvinotevera:
- arterial hypertension;
- kuvapo kwemaitiro akaipa (nicotine, doro);
- zvirwere zvekuvhenekera;
mamiriro e-pre-eclampsia; - kuvapo kwehutachiwana muhutano hwekare;
- multiple pregnancies;
- Rhesus-kukakavara;
- gestosis;
- kutadza kwema fetal body body size.
Inofanira kurehwa kuti hapana kudzidziswa kunodiwa.
Nokudaro, kuitira kuti mukadzi ari munzvimbo akwanise kunzwisisa kuti iyi ndiyo ultrasound pamwe ne doppler, yakagadzwa panguva yekuzvitakura, zvakakwana kubvunza chiremba anopa murayiridzo pamusoro peizvi.
