Munguva yekutanga kwemutatu , mwana wemwoyo inotanga kunotanga kune imwe nzvimbo inenge mazana zana neminomwe paminiti (bpm) inenge mavhiki masere ekupera kwemavhiki (nguva yekutanga kuonekwa), nhepfenyuro pamasvondo gumi nemanomwe (dzimwe nguva kunyange kusvika kumazinga akaenzana nekuputika 180 paminiti) uye zvishoma nezvishoma zvishoma nezvishoma apo fetus inoswedera pedyo.
Ultrasound Yakaratidzwa Slow Fetal Heart Rate muTree Trimester. Ndichati Ndisarudze Here?
Apo mwoyo unoterera unonoka kudarika zvaunotarisirwa, chiremba angaona kuti kune chimwe chikonzero chekufunganya uye anokurudzira aite-up ultrasound kuti uone kukura kwomwana.
Iko kunononoka kwemwoyo kunokonzera kunetseka nokuti zvidzidzo zvinoratidza kukwirira kwakanyanya kwekusununguka kwepamuviri apo mwana ane chirwere chemwoyo chepashoma kupera zana neminomwe pamasvondo matanhatu kubva pamuviri kana pasi pemapfumbamwe makumi maviri neminomwe paminiti pamasvondo matanhatu kusvika ku7.
Kana yako ultrasound ichiratidza kuti mwana wako ane mwoyo unononoka, iwe unotya uye unonetseka, kunyanya kana wakanga uchitsvaga ruzivo pamusoro pezvinorevei izvi. Iwe unganzwa uchinetseka kuti unofanirwa kumirira vhiki kwekutevera. Asi zvinosuruvarisa, hapana nzira yekuudza zviri kuitika kunze kwekumirira. Dzimwe nguva kutora kwomwoyo kwomwana kunowanzosimudzira, uye ipapo kuberekwa kuchaenderera pasina zvimwe zvinetso. Asi zvinosuruvarisa dzimwe nguva mugumisiro unoenda kune imwe nzira. Hapana iwe iwe kana chiremba wako anogona kuita kuti huve nehupenyu hwekupedzisira. Apo mimba inokanganisa mushure mekuona kucheka kwe fetal heart rate, chikonzero chacho kazhinji kacho chromosomal zvisiri izvo zvaivepo pakuberekwa.
Kukosha kweAxsound panguva yekudzivirira
Panguva yekuzvitakura, ultrasound inoshandiswa nekuda kwezvikonzero zvakawanda kusanganisira zvinotevera:
- Kudanana (kuongorora kunze kwezera re fetus)
- Aneuploidy (chromosome) kuongorora
- Cervical length test
- Kutsunga kwehutano hwakanaka ( biophysical profile )
- Anatomical assessment
Mumasvondo gumi nemasere kusvika masere ekuberekwa, makore ekuberekwa anogona kugadzirirwa kushandisa ultrasound.
Zviyero zvakasiyana zvinoshandiswa kuenzanisa zera remwana kusanganisira zvinotevera:
- Biparietal diameter
- Head circumference
- Mabdominal circumference
- Femur urefu
Kururama kwekufambidzana kunosanganisira kana kudarika mazuva manomwe. Mune mamwe mazwi, zera remwana rinofungidzirwa mukati mevhiki. Pamasvondo makumi maviri nemaviri, kururamisa uku kunopera uye ultrasound inonyatsoshandiswa kutarisa fetal kuyerwa nekukura.
Kushandisa ultrasound, mazwi e fetal heart anogona kunzwika pamasvondo anenge gumi 'gestation. Zvinotora masvondo gumi nemasere kusvika makumi maviri kuti anzwe kubatwa kwomwoyo kwomwana achishandisa fetoscope.
Ultrasound ndiyo yemhando yegoridhe, kana nzira yakanakisisa, kuziva kana mwana wacho ari mupenyu. Zvinosuruvarisa, kana mwana mucheche aripo asi hapana kushaya mwoyo kunowanikwa, ipapo fetus yakafa.
Asina kuchena Heartbeat Anoratidzwa Panguva Yacho Ultrasound
Dzimwe nguva munguva yekutanga kwekutanga kwekuita pamuviri, hazvisi pachena kana pane kushaya mwoyo. Muzviitiko izvi, mimwe miedzo inofanira kuitwa kuti ione kana mwana ari mupenyu. Iyi miedzo inosanganisira serial beta hCG mazinga, rudzi rwekuzvitakura hormone.
Fetal Demise Panguva Yokurara Kwemazuva Ekupedzisira
Munguva yekudzivirira kwekupedzisira, chiratidzo chokutanga chekuberekwa kwekuberekwa kazhinji kazhinji kusina kufamba. Kana mwana asati ari kufamba, ultrasound inogona kushandiswa kuona utanha hwemwoyo uye kuzarura chikonzero chekushaiwa kwekutora kufamba.
