Chirwere chemuviri wechikamu chikamu chechivharosi, kubatana nemukadzi uye uterine cavity. Inoita segomba duku kana pharynx. Chirwere chechibereki chakakonzerwa nemucosa, masero ayo anogadzira purasitiki yakasimba panguva yekuzvitakura, iyo inodzivirira placenta uye fetus kubva pakupinda kwezvirwere zvakasiyana-siyana.
Basa rayo nderokuti:
- kugoverwa kweropa panguva yekuenda kumwedzi;
- kugamuchirwa kwepermatozoa nekugonesa kupinda kwavo mubereki kuitira chinangwa chekudyara maoocyte .
Norm yemakwenzi echirwere akaenzana pakuberekwa
Kureba kwechirwere chechibereki panguva yekuzvitakura kuri kusvika 4 cm.
Izvo zviyero zveganda remudzimai panguva yekuzvitakura zvinongororwa panguva yekuongorora, pamwe nekushanda kwe intravaginal ultrasound. Muchizvaro chepamuviri, kubhurwa kwekunze kwechirwere chechibereki kwakasimba zvakavharwa nekuda kwebasa remumutsipa wemumuromo, iyo inobatsira fetus kuti irambe iri mudumbu.
Apo kuswedera pakuberekwa kwechirwere kunotanga kupfupisa uye kunonyorera kuti zvifambise kufamba kwecheche kuburikidza nekuberekwa kwechirwere. Kervical canal, yakavharwa panguva yekuzvitakura, inotanga kuwedzera. Nekutanga kwekurwisana nguva dzose, inotanga kuwedzera zvakanyanya: pakutanga kwe 2-3 cm, uye kusvika kune masendimita 8. Chiyero chekuvhara chirwere chechibereki panguva yekuzvitakura kunobatsira vanachiremba-gynecologists kuti vasarudze nguva yasara asati aberekwa mwana. Apo mhandara uye chibereko, iyo inobatanidza chirwere chemuviri wechikanda, chinotanga ne 10 cm, kugadzira nzira imwe chete yemadzitateguru, izvi zvinoratidza kuzarura kwakakwana kwomukati .
Kana, panguva yekuzvitakura, chirwere chechibereki chinoparadzaniswa uye chakawedzerwa pamusoro pechimiro, uye kuchine nguva yakawanda isati yatanga kusununguka, ichi chiratidzo chekutyisidzira kusati kwapera kuberekwa. Kazhinji kazhinji, izvi zvinogona kuitika pakati pekuzvimba nekuda kwe isthmico-cervical insufficiency.
Kuvhura kwepakutanga kwechirwere chemuviri wekodha kunokonzerwa nekuwedzera kwehukuru hwema fetal, iyo ine simba rakawandisa pamuromo wechibereko, iyo inotungamirira pakuwedzera kwayo. Izvi zvinokurudzirwa nekushanda fetal movement uye zvakanyanya
Kana kuongororwa kweIsthmico-cervical kusagutsikana mumukadzi kunopupurirwa, mukadzi wacho anowanzobvunzwa kunyorera chivharox kana kuisa pamutsipa chindori chisingaregi kuti chizarure.
Mukuwedzera, mukadzi anofanira kurega kuita zvepabonde uye kurega kuita zvepabonde.
Kana chibereko chemukadzi kazhinji chiri mukutaura, chiremba anopa mazano pamusoro pokuti ungaderedza sei. Kuchengetedza kurapwa mumamiriro echipatara kunogonawo.
