Kusiyana nekutanga, kuberekwa kwechipiri kunogona kuitika kare - pamasvondo 37-38, kunyange zvazvo kazhinji mukadzi ari kubvisa mwana asati asvika musi wekupedzisira wevhiki makumi matatu nemakumi matatu nemakumi mana. Ichokwadi, 3 kuberekwa kunowanzoitika nokukurumidza, uye kana 36-37 vhiki yekubata inotanga - zvakakosha kugadzirira chero chinhu.
Asi pamasvondo makumi matatu, mwana akazara uye akazvigadzirira kuberekwa: muvhareji wekuyera anenge anenge 3 kg, ganda haichazofukidzirwa ne fuzz yepakutanga, girasi yepakutanga iri mumapango eganda, zvipikiri zvinoputira mubhedha wemisodzi. Muvakomana, mazamu acho atoenda mumutambo, vasikana vane hombe yakawanda yakafukidza zviduku.
Precursors of delivery pamavhiki 37
37 vhiki yekutanga kana yechipiri pamuviri - nguva iyo inopedzisira yekuberekwa inogona kuonekwa. Kutanga, mukadzi ane manzwiro ekuti mudumbu iri kuoma kubva panguva nenguva, uye dzimwe nguva pane zvisiri izvo zvinopesana - zvinonzwa zvinorwadza mudumbu rezasi. Kuberekwa kunoitika kakawanda pamasvondo makumi matatu kana chiviri chechipiri chikaitika mushure mokutanga kusvika kune makore 3-5, sezvo chibereko chechivharo chinotanga nekukurumidza, uye kana mushure mokunge, chibereko chechipiri chinoenda zvakafanana neyekutanga.
Munguva iyi, mucous yellowish kubuda kubva mumuviri wemukati kunokwanisika (mucus plug inogona kubuda mumuromo wekervical), asi kana kubudiswa kuri purulent, kusviba kana ropa, pamwe chete ne pruritus kana kurwadziwa, uku ndiko kusununguka kwezvirwere uye inofanira kubvunza chiremba. Uye kana mvura yakawanda yemvura ichibuda uye marwadzo ari mudumbu rezasi anowedzera kuipa - zvichida, kuberekwa kwakatanga uye amniotic fluid yakabva, uye iwe unofanira kuenda pakarepo kuchipatara.
Kufungisisa kweamai mumavhiki makumi matatu nemaviri
Panguva ino, chibereko chinoramba chichikwira uye chikafu mukati memudumbu (vakadzi vanowanzotambura nekushushikana, kuora mwoyo, kurwadziwa mukati mudumbu). Asi panguva yekuzvitakura kwechipiri, chibereko chinogonawo kuderera pamasvondo makumi matatu, sepakutanga kuberekwa, kunyange izvi zvisiri chiratidzo chekuita kwavo. Nemhaka yekumanikidzwa kwemukati, kuvhiringidzika kunogona kuitika, zvironda uye zvirwere zvevaricose zvinogona kuonekwa nekuda kwekumanikidzwa mumatavi maduku.
Kazhinji chibereko chinomesa vhudzi, kuputsa kuputika kwetsvo, kunyanya kubva kurudyi. Izvi zvinotungamirira kumarwadzo, kuvhiringidza maitiro muitsvo, kuwedzerwa kweropa.

Fetal size pamavhiki 37
Kudzokorora kubereka mwana, unozivikanwa nekukurumidza kwahwo, hauna kushamiswa, pamasvondo makumi matatu, inonzi ultrasound inowanzogadzirirwa kutarisa ukuru hwe fetus asati abereka uye kusarudza kuti ungaitungamirira sei. Munguva iyi, mharidzo ye fetus inofanira kuva musoro. Kukudza kwehurukuro chiratidzo chechikamu chekudya, uye gumbo, oblique kana kutenderera kune chiratidzo chisingaverengeki, sezvo zvichibvira kuva nemwana pamasvondo makumi matatu, uye zvakaoma zvikuru kutendesa chibereko kuva chinzvimbo chakanaka nekuda kwekukura kwayo kukuru.
Hukuru hukuru hwe fetus pavhiki 37:
- BDP (biparietal size yehenya) -90.1 mm;
- DB (kureba kwehudyu) - 70.3 mm;
- SJ (kureva mudumbu mamitare) - 98.4 mm;
- LTE (ukuru hweparietal yakakura yehenya) - 114 mm;
- SDHK (kureva kureba kwemhino) - 90,1 mm;
- kuwanda kwepascenta 37.8 mm, zviyero zvitatu zvekukura, pasina hutachiwana hutsva.
Kureba kwendarira ye amniotic fluid munzvimbo isina zvikamu zvechibereko - kusvika kusvika 70 mm, panguva iyi yemvura dzimwe nguva inenge ine makore - muvhiki yekupedzisira yekudzivirira mukati mavo ndiyo yakatanga girasi. Imwe cheki ndeyekuti pane mutsara wembilical mumutsipa uye kuti anowedzera sei mutsipa wake kangani. Kupindirana kwema fetus kunofanira kunge kuripo, 120-160 paminiti, kufamba-fetera-kushanda, uye pakuongorora inowanzoongororwa kana fetal hypoxia kana kukanganiswa kweropa mukati meUterine arteri uye umbilical arteri (dopplerography maererano nezviratidzo) inoonekwa.
