Doppler inzira yekutariswa kwepabonde, iyo inonzi ultrasound. Dopplerometry panguva yekuzvitakura inowanzoitwa panguva imwechete ne ultrasound uchishandisa zvakakodzerwa nemichina ye ultrasound.
Dopplerometry inobva pakufungidzira kwehuwandu hwezwi, iyo inoshanduka apo inoratidzwa kubva pane kufamba kweropa. Dopplerometry inokubvumira kuti uone kubhururuka uye chimiro chekuyerera kweropa mumidziyo yesimbi yembilical uye chibereko chemukadzi, pamwe chete neaorta uye pakati peperesi yemazamu ye fetus. Kubva pamigumisiro yechirongwa ichi, zviratidzo zvekusawirirana mubasa reparcenta neropa rekuyerera zvakasimbiswa, nekuda kwekuti mwana haagoni kugamuchira zvinhu nokuda kwekuvandudzwa kwayo. Dopplerometry inoita kuti zvibvirire kutsvaga fetoplacental kusakwana kana fetal hypoxia panguva yakakodzera.
Dopplerometry inoitwa sei panguva yekuzvitakura?
Nzira ye doplerometry inogona kuitwa kakawanda panguva yekuzvitakura. Izvo zvinorwadza uye zvakachengeteka kune amai uye remangwana mwana. Ita dopplerometry mukudzivirira uyewo yakakurumbira ultrasound, misiyano chete ndeyokuti nedopplerometry, ropa rinoyerera rinofungidzirwa, izvo chiremba anoona pane kuongorora mufananidzo wemuvara.
Dopplerometry inoitwa mushure memavhiki 23-24 ekugomba. Chokutanga, dopplerometry inorayirwa vakadzi vane pamuviri vari pangozi. Izvi ndezvokutanga, vakadzi vane chirwere chekushaya ropa, chirwere chepfungwa, gestosis, zvirwere zvemwoyo yemagetsi netsvo, kuvapo kweRh-antibodies muropa, chirwere cheshuga cheshuga . Bhuku iri rine ngozi rinosanganisira vakadzi vane pamuviri vane nguva isati yakwana yokuputika kwelacenta, vazhinji-uye malodontics, chromosomal pathology ye fetus uye zvimwe zvirwere.
Parameters doplerometry mukuzvitakura
Dudziro ye dopplerometry pakuzvitora inoderedzwa kusvika kuongororwa kwezvinhu zvakasiyana-siyana zvinoratidza kusvika kwekuvhiringidzwa kweropa. Sezvo kuwanda kwekuyera kwekuyerera kweropa kunowanzoomeswa, zvienzanidzo zvinoshandiswa zvinoshandiswa mu dopplerometry. Izvi zvinosanganisira:
- IR - index yekumanikidza;
- PI ndiyo nhamba yepulsation;
- SDO - systolic-diastolic ratio.
Nhamba dzakakwirira dzinoratidza kuwedzera kukurira kweropa, asi zvinyorwa zvishoma zvinoratidza kuderera kwekudzivirira kubuda kweropa. Kana IR iri kupfuura 0.773, uye SDR inopfuura 4.4, zvino izvi zvinoratidza zvinetso zvinogona kuitika.
Chimiro che dopplerometry ndiko kusina kwekuvhiringidzika mune chidzidzo. Asi kana zvimwe kukanganisa kuwanikwa, mukadzi haafaniri kuora mwoyo. Mitemo yeDopplerometry pakuzvitora ichabatsira kururamisa nguva yekuzvitakura, sarudza kurapa kwakakodzera kunodzivisa kuora kwemwana.
Mushure mokuongorora majeti, zviyero zvinotevera zvekuvhiringidzika kwepakati zvakasikwa:
1 degree:
- A-fetoplacental ropa inotenderera inochengetedzwa, uteroplacental ropa inopera inodedera;
- B - uteroplacental ropa inoputika inoparadzaniswa, nzvimbo yepamusoro-yakachengetedzwa;
2 digita : kutyora kwechibereko uye chinopisa,
3 degree : kunyanya kukanganisa mu fetoplacental blood flow panguva yekuchengetedza kana kushungurudza utero-placental blood flow.
Kwatingaita dopplerometry muhutano, mukadzi anonyatsoudza chiremba ari kutungamira pamuviri wake, kana chidzidzo ichi chinoitwa mune imwe nzvimbo yezvechiremba iyo mukadzi anocherechedza, kana mukadzi ane pamuviri anotumirwa kunharaunda yakakodzera yepininatal yakagadzirirwa nemichina yakakodzera.
