Nguva yekugadzirisa mukadzi kune vhiki makumi matatu nemana kubva panguva yekuberekwa. Muvakadzi vakawanda, pamuviri unotora mazuva 266. Asi hazvibviri kuverenga zuva rekuzvarwa patsva kusvikira zuva rakapfuura. Zvakawanda zvinoenderana nehutoni hwemukadzi, hutachiona uye hutachiwana hwemwana asati aberekwa, nezvimwewo. Asi mushure memavhiki makumi matatu nemaviri ekuberekwa, fetus inogadzirira hupenyu huzvimirire (nguva yakazara). Mushure mekunge nguva iyo mwana akaberekwa anokwanisa zvachose.
Asi mwana mushure memavhiki makumi maviri nemaviri ekuberekwa anoonekwa sekutambura , uye basa rinogona kuendeswa nematambudziko akakomba emucheche. Nokudaro, izwi rekuzvitakura rinokosha kuti usati wamboziva zuva rakatarwa rokuberekwa, asi pane kuziva panguva iyo kuberekwa kwomukadzi kuchaonekwa kwakanaka, uye mwana - nguva yakazara.
Nguva yekuzvitakura obstetric uye fetal - kusiyana
Nguva yekudzivirira pamuviri masvondo makumi mana, uye embryonic gestation period ndeye 38. Kusiyana kwemazuva 12-14. Kubata chibharo kunotanga musi wekutanga wemwedzi wapera. Nguva yekubamoniya inotanga kubva pazuva rekuberekwa (kubva pazuva rekuvhara, izvo zvinowanzouya musi we14 kubva pakutanga kwemwedzi pamwe chete kana kudarika mazuva 4).
Nzira yekuverenga sei kubata pamuviri?
Kubata chibharo uye kunyanya (embryonic) pamuviri kunopera kwemavhiki maviri. Mukuita, nguva yekumbryonic haifaniri kuonekwa uye inogumira kuverenga chete chigamba chemagetsi. Kana mukadzi asingazivi zuva rekutanga kwekupedzisira kuenda kumwedzi, asiwo zuva rekuberekwa, ipapo mitsetse yemumikononi yekuzvitakura yakarurama. Nguva yekubata chibharo inotora mazuva 280 kubva pazuva rokutanga romwedzi wapera. Maererano nemigumisiro ye ultrasound, maererano nematafura, inotsigirwa kuti fetus inofananidzwa ne-obstetric, asi kwete embryonic, gestation.
Ndinokwanisa here kuverenga zuva rokuberekwa kwemutsara wekudzivirira?
Nzira yakareruka yekuverenga zuva rinotarisirwa kuberekwa inogona kuonekwa seyi inotevera: kubva pazuva rokutanga rekupedzisira mwedzi woga woga kuwedzera mazuva 280 (fomu yaKeller). Zvisinei, pakuita izvi zvakaoma uye zuva rinogona kuberekwa rinotsanangurwa nemaitiro maviri akafanana.
- Pakazosvika zuva rekupedzisira kwegore rega rega, mwedzi mapfumbamwe nemazuva manomwe anowedzerwa.
- Kubva musi wekutanga kwemwedzi wapera, mwedzi mitatu inotorwa uye mazuva manomwe anowedzerwa.
Mavhiki kubva pazuva rokutanga rekupedzisira kuenda kumwedzi. Nokuda kwechiremba chiremba, vhiki makumi mana makumi mana akaparadzaniswa mumashoko matatu. 1 trimester inosanganisira mavhiki 1-14 ekudzivirira, 2 trimester - masvondo 16-28, uye 3 trimester - kubva pa29 kusvika ku40.
Kubata chibharo uye nguva ye ultrasound
Hazvina kunaka kurangarira kuti ultrasound inoratidzirwa ne-obstetric kana embryonic gestation. Pane kudaro, pane zvinopesana, maererano nematafura chaiwo, umo mavhareji akaenzana emucheche anogadzirwa nokuda kwekuvharirwa kwemavhiki mashoma, tarisa kuti vateereri vavo vakagadzikana. Kazhinji uhu hwema fetus hunofananidzwa nenguva inopesana uye kusapedza vhiki imwechete: mwana wacho anowanzoita. Kana izwi rokuti ultrasound risingapfuuri zvisingabviri, izvi hazvirevi kuti izwi rakashandura rinenge risina kuongororwa, asi chimwe chinhu chinodzivisa kufanirwa kwekuvandudzwa kwe fetus. Zvimwe zvinokonzera kukanganisa kwekuwedzera kwemukatikati:
- chirwere chaamai;
- kukanganisa kwekushanda kwepasentaa;
- multiple pregnancies;
- chromosomal kusagadzikana kwe fetus;
- intrauterine infections;
- miitiro yakaipa yaamai;
- kudya kunovaka muviri, nezvimwewo.
Kana izwi rokuti ultrasound rinowedzera kuvhiringidza, saka kazhinji kacho chikonzero chichava chiremera chikuru checheche asina kuberekwa (nemhaka yehutano, chirwere cheshuga, kudya kwaamai panguva yekuzvitakura).
Zvinokwanisika kuti zuva rekupedzisira kuenda kumwedzi rakagadzirirwa nemukadzi zvisina kururama uye kana achiyeuka musi wekubata pamuviri , zviri nani kuverenga nguva isina simba kuburikidza ne embryonic, kuwedzera kumavhiki maviri ekupedzisira.
