Zvichipa nzvimbo yakakwana yemucheche mudumbu, musoro wemwana uri pasi uye nzira yekutanga inowanzobuda. Asi muzvikamu zvitatu zvemazuva ose, fetus iri iri mudumbu nenzira yakadai yemakumbo (mhedziso yegumbo), bundu re fetus (gluteal) kana makumbo ane mabheti (kusanganiswa kwepilvic presentation) ari pamusoro pechipfuva uye akatenderedzwa kusvika pavanopinda pamapapiro emukadzi.
Kuberekwa kunogona kugadziriswa zvakasununguka pasina zvinetso, asi kazhinji mamiriro ezvinhu ane ngozi kune amai nevana.
Chipfevic kupupurirwa kwe fetus - zvinokonzera:
- polyhydramnios uye, nokudaro, kuwedzerwa fetal activity;
- kuvapo kwemapapiro maduku, nzvimbo dzisina kukwana dzepentecenta, kukura kwe fetus zvisizvo;
- kuratidzwa kwekushaya zvokudya zvinovaka muviri, kukura kusina kukwana kwechibereko;
- kuderera kwekutaura kwechibereko.
Nzira yekuziva sei kupera kwepilvic?
Muchengeti wezvipembenene anotungamirira kuongorora kwekudzivirira kwekunze kwechirongwa chepakati huru yepakutanga kwechimiro chisina kujeka uye kuwirirana kwakanyanyisa pamusoro pekupinda kumapanga. Chiratidzo chekudzivirirwa kwemuviri we fetus ndiyo nzvimbo yakakwirira yepasi pechibereko. Kupindirana kwema fetus kunogona kunzwika kuvakadzi vane ruzivo rwepachevic pamusoro pevheji. Uyewo, kuti ujekese kuongororwa, sarudza mazamu ekuongorora uye ultrasound.
Kuve nepamuviri nemukomana weplvic?
Nzira yekudzivirira haisi yakasiyana nekufambiswa kwekugara pamuviri. Pavhiki 32, amai vemazuva anouya vanorayirwa kune imwe nzira yezvidzidzo uye vanokurudzira kupfekedza bhanhire neveplvic presentation.
Kana musati mavhiki 37-38 munhu muduku akaoma asingashanduri nzvimbo yake, kuberekwa kunoitwa nekufungisisa kushandiswa kwepadvic. 10-14 mazuva asati atarisirwa zuva rokutakura, mukadzi ane pamuviri ari muchipatara muchipatara, uko vanachiremba vanosarudza nzira yekuendesa.
Biomechanism yebasa nekutaura kwepadvic
Muchipatara vanosarudza kuita nekuberekwa kwekuzvarwa kwepanyama kana kuti kuvhara nekutaura kwechibereko che fetus.
Panguva imwe chete, zvinhu zvakadai sokuti:
- rudzi rwekuberekwa kwekuberekwa kwevana, panguva ipi yezera;
- iyo dzidzo uye chiitiko chepamuviri pekare;
- iyo yamuviri wepamuviri iye zvino;
- kuvapo kweEdema;
- kuvapo kwehuwandu hwemhepo;
- renal dysfunction;
- inofungidzirwa uremu uye mamiriro ehutusi;
- uwandu hwemapapiro amai;
- mune mamiriro akaita chibereko chechivharox, uye kana yakagadzirira kubereka;
- mhando yekutaura kwepachivi;
- nzvimbo ye fetal head.
Kana zvipingamupinyi zvaive nezvakaitika panguva yekuzvitakura, mukadzi wacho ane pfupa shoma, kurema kwomwana kunodarika 3 500 gramu, nguva yemukadzi uyu anopfuura makore makumi matatu nemakumi matatu nemashanu uye ane dambudziko rokutanga pamuviri, zvino vanachiremba mune makumi masere makumi masere ematongerwo emhosva vanogadzirisa chikamu chekusiya.
Migumisiro yekutaura kwepadvic
- Kana chisarudzo chikaitwa kuti chiite chikamu chekudzivirira, ipapo chironda chinoramba chichiri pachibereko chemukadzi.
- Mamiriro echeche akazvarwa mumusana wekudzivirira kwepanyama pakusununguka kwemhuka haisi nguva dzose inogutsa. Kubudirira kunogona kuitika kwe hypoxia kunogona kukonzera kushungurudzika kwepfungwa mumwana.
- Panogona kuve nekuparadzaniswa kwekubatanidzwa kwechiuno uye zvinetso mumamai.
Asi kana zviyero zvose zvinosangana, vana vanozvarwa vakagwinya, uye havakwanisi kune vamwe.
