Panguva yekuzvitakura, huzhinji humwe humwe hunoitika huri mumuviri womukadzi. Izvi zvinokonzerwa nokuumbwa kwebasa rekushanda kwemaamai-fetus. Kuchinja kukuru panguva yekuzvitakura kunowanikwa mukubereka, kunyanya chibereko. Hukuru hwechibereko chinoshandura : hukuru, chimiro, kusagadzikana, nzvimbo uye reactivity ye chibereko. Chibereko chinokura panguva yose yekuzvitakura sezvo fetus inokura. Kureba kwechibereko pakupera kwekuita pamuviri kune chiyero chemasendimita 37. Chibereko chinowedzera kusvika 1000-1500 g.
Kureba kwekumira kwepasi pechibereko kunotsanangurwa kubvira mavhiki 8-9 ekudzivirira. Ichi chiratidzo chinokosha chinobatsira kutanga nguva chaiyo yekuzvitakura, kutevera kubudirira kwevana vose uye pamuviri pamwe chete.
Kusarudza kwekumire kwakakwirira kweUterine fundus
Kureba kwekumire kwemuviri wechibereko kunotsanangurwa pamusoro pekumucheto kwepamusoro kwe pubic symphysis, kubva pasi pechiberekero kusvika kumhazha, chirongwa che xiphoid nechishongo chisina chinhu. Kureba kwemiremo ye uterine fundus pamusoro pe pubic symphysis inotsanangurwa necentimeter tepi kana tasometer.
Nzira dzekumira kureba kwepasi pechibereko
Ikoko hakuna chimiro chakakwana chekumira kwehumi hwe uterine fundus panguva yekuzvitakura panguva dzakasiyana. Ukuru hwemamiriro ekudzika kwechiberekero kunobva kune mutemo webumbiro wemuviri wemukadzi, pauremu hwake nekukwirira, pamusana wehutachiwana hwemucheche uye pamhando ipi yekuzvitakura. Asi zvakadaro, tinofanira kuomerera kuhuwandu hwehutano hwehupamhi hwemamiriro ekudzika kwechibereko panguva dzakasiyana-siyana sechinhu chakasiyana chechimiro. Mumavhiki maviri ekupedzisira ekutora pamuviri, kukwirira kwemaimire e uterine fundus ndeye 36-37 cm, iyo ndiyo yakakwirira yepamusoro yechibereko chepamuviri wese. Pakutanga kwebasa pasi pechibereko chinoburuka, kukwirira kwaro kwaro panguva iyi ndeye 34-34 cm.
Kana kukwirira kwechimiro chechibereko chekuberekwa chiri mberi kana shure kwechinguva chekuita, iyi inguva yekufunga pamusoro pekugona kweropa
Kureba kwemamiriro ekudzika kwechiberekero kana kaviri zvisingatauri maererano nekugumira kwenguva, mberi kwechiratidzo ichi, sezvo chibereko chichanyanya kutambanudzwa kupfuura nekuzvitakura kamwe. Mukuwedzera pakuve nemimba yakawanda, zvimwe zvikonzero zvekuwedzera kukwirira kwehumi hwe uterine fundus maererano nezwi irizvino rekudzivirira richava:
- polyhydramnios
- kuvapo kwemukomana mukuru;
- kukanganisa kwekuziva nguva iripo kunogona.
Iyo yakaderera yakadzika yepasi pechibereko, iyo isingatauriki nechinguva chemazuva matatu kana kupfuura, inoratidza kuti zvinogona kuitika pakuita pamuviri, zvakadai se:
- hypochlorism pakuberekwa ;
- kunonoka pakukura kwe fetus;
- uyewo kukanganisa mune tsanangudzo yenguva ino inogoneka.
