Nzira yekuziva sei kutanga kwekuberekwa mumbwa?

Ultrasonography inogona kubatsira kuona huwandu hwemazuva ekusununguka kuburikidza nekuyera biparietal musoro dhayamita ye "fetus" uye nekushandisa yakakosha scoring formula mumbwa dzemasayizi akasiyana.

Kubva pazuva remakumi mana nemaviri epamuviri, skeleton ye "fetus" inotanga kuoneka pamaradiographs, kubva pazuva rechi42 kusvika ku45 mapfupa edehenya anoonekwa, kubva pazuva rechi49 kusvika rechi57 - mapfupa epelvis, kubva pazuva rechi59 kusvika rechi58 - mazino.

Mazuva maviri kusvika ku2 vasati vasununguka, imbwa dzingatanga kuratidza zviratidzo zvekunakidzwa, kusagadzikana, nesting, kuwedzera weti uye tsvina, uye kuderedza kudya.

Izvi zvinokonzerwa nekuwedzera zvishoma nezvishoma mukudzivirira kwechibereko. Pazuva rekusununguka, chido chinogona kunge chisipo zvachose.

Kuwedzera kwezamu kunotanga muhafu yepiri yekuzvitakura. Kuyamwisa mune mamwe matinji kunoonekwa kubva pazuva remakumi mana ekuzvitakura, mune mamwe nguva pfupi asati azvara, mukati mavo kana pakarepo mushure.

Kuwedzera kwekusangana kwehomoni relaxin muropa kunotungamirira kukuwedzera uye kupfava kwechiuno (0-2 mazuva asati aberekwa), kusununguka kwemuromo wechibereko uye, sechikonzero, kuparadzaniswa kwemucous plug (0-7 mazuva. vasati vasununguka).

Kudonha kwekushisa kwemuviri kusati kwasununguka chiratidzo chakavimbika chekutanga kwekushanda mumbwa, zvichiratidza kuderera nokukurumidza kwemazinga eropa reprogesterone pasi pe 1 ng/mL, iyo thermogenic hormone inochengetedza mimba. Kupisa kwemuviri kunodonha zvakanyanya (kusvika pa36,7-37,7 degrees).

Iwe unofanirwa kuziva kuti mushure mekudonha, tembiricha ichakwira zvishoma (kusvika kunenge 37,2 madhigirii) uye ichachengetwa mukati mechikamu chekutanga chebasa. Panguva ino, maawa 8-24 anoramba asati aonekwa puppy yekutanga.

Zvinokurudzirwa kutanga kuyera rectal tembiricha kubva 54-55th zuva pamuviri 1-2 kanomwe pazuva panguva imwe chete.

Kuderera kuduku kwekushisa kwemuviri kunogona kuitika muvhiki yekupedzisira yekuzvitakura, sezvo chiyero cheprogesterone muropa chinoderera zvishoma nezvishoma. Zvisinei, mune dzimwe imbwa, hazvibviri kugadzirisa nguva yekudonha kwekushisa nenzira iyi.

Kuputika kwekutanga amniotic sac, kubuda kweyero-green discharge (mvura) kubva kunze kwenhengo dzepabonde kunoratidza kupatsanurwa kwe placenta uye kutanga kwechikamu chechipiri chekushanda (danho rekuedza - kudzingwa kwe fetus) ; uye pamberi pekuonekwa kwembwa yekutanga, maawa 1-2 anoramba aripo.
