Izwi rokuti kuchema kwekukura kwe fetus ye fetus inoshandiswa navanachiremba apo fetal muviri wehutachiona hunowanikwa neanopfuura 10% yehuwandu hwehutano hwekubata. Chirwere chekutsvaira intrauterine kukura kana kuti fetal hypotrophy kune marudzi maviri - akaenzana uye asinganzwisisiki.
Nechiratidzo chema intrauterine hypotrophy, nhengo dzose dzakaderedzwa zvakafanana, asi hypotrophy isingaenzaniswi inoratidzirwa nekuvandudzwa kwemasaga uye uropi, asi nhengo dzomukati dzinoshandiswa. Kazhinji chimiro chisingaenzaniswi chekutsvaira kwema intrauterine chinowanikwa mumatatu matatu ekuzvitakura nekuda kwematambudziko akasiyana ekudzivirira.
Nhanho uye zvikamu zvekuvandudzwa kweprorauterine
Pakati pese, nguva yekutanga yekuberekwa kwekukura kwomwana inoitika mumatanho matatu makuru:
- Yokutanga, danho rekutanga - ino ndiyo nguva yemusangano weii nehuta, kuwedzera kwekuumbwa kwe zygote, masero ayo anotanga kuwedzera zvakasimba. Ichi chisikwa chiduku chinopinda mumuviri uye chinoshandiswa mune chimwe chemasvingo aro.
- Iko kunouya yechipiri nguva - embryonic. Icho chinopfuurira kusvikira vhiki yechigumi nembiri. Munguva iyi mwana wacho anonzi izwi rechiremba "embryo". Iko mumwedzi mitatu iyo masangano ese uye nhengo dzomurume muduku anouya dzinoumbwa. Nokudaro, nguva yechipiri (kana mune imwe nzira - yekutanga trimester) inzvimbo inokosha zvikuru yekuzvitakura.
- Mushure mekunge mwedzi mitatu inotanga nguva yekutakura, apo mwana ari kukura nokukurumidza nekuwana uremu, achiramba achivandudza muviri wake.
Kurara munguva yekubereka mwana asati aberekwa - zvinokonzera
Zvinonyanya kukonzerwa nekupererwa kwekuwedzera kweprauterine zvinosanganisira kusagadzikana kwekugadziriswa kwepakati, chromosomal kusagadzikana (semuenzaniso, Down syndrome), doro uye kushandisa zvinodhaka, kusvuta panguva yekuzvitakura, kutora mimba yakawanda, mamwe marudzi ehutachiona (cytomegalovirus, toxoplasmosis, rubella kana syphilis), yakaoma kusagadzikana.
Zvinokonzera intrauterine kusagadzikana kwema fetus kunogona kuva mamiriro ezvinhu anokonzera kudarika kwekupararira kweropa. Izvi zvinosanganisira kuwedzerwa kana kuderera kweropa, chirwere chepfungwa, chirwere cheshuga mellitus nemavhu mungozi, toxicosis yehafu yechipiri yepamuviri.
Kukura kwekukura kwekukura kwekukura kunotungamirira kune zvirwere zvakasiyana-siyana zvisingagumi mumamai, zvichiita kuti muviri wake udhakwa uye kusava nemhepo. Izvi ndezvirwere zvisingaperi, maronchitis, tonsillitis, zvirwere zvokuputika, pyelonephritis, mazino anokanganisa, chirwere chekushaya ropa, zvirwere zvepfungwa.
