Amniotic fluid kana amniotic fluid inzvimbo yakadzika mumvura inopoteredza mwana kubvira pakuberekwa kwekutanga uye kusvikira panguva yekuberekwa. Munharaunda iyi, mwana anonatswa zvose mukushisa uye munharaunda dzakawanda. Mvura inodzivirira iyo kubva mukukuvara kwemagetsi, inokurudzira, inopa pfungwa yekuchengeteka.
Sezvo amniotic fluid ine basa rinokosha panguva yekuzvitakura, vanachiremba vanonyatsotarisa. Kunyanya inoshungurudza zvakadaro sechiratidzo sehuwandu hweamniotic fluid. Kazhinji, pamuviri we amniotic fluid inofanira kunge iri 500 uye kwete kupfuura 2000 ml.
Zvechokwadi, panguva yayo yekutanga kare ndeye 30 mamiriyoni chete, asi pedo nemavhiki makumi matatu, ivhu rinosvika pachikomborero che 1500 ml. Pedyo nekuberekwa, iyi bhuku inoderera kusvika anenge 800 ml. Kuumbwa kweamniotic fluid inochinjawo. Kana pakutanga kwepamuviri iyo yakafanana mukugadzirirwa kusvika kune plasma yeropa, zvino mumagumo ekupedzisira, zvibereko zvehupenyu hwemwana zvinosanganiswa pano. Ichokwadi kuti mvura inonatswa - inenge maawa matatu, iyo yakanyatsorongedzwa.
Mabasa eamniotic fluid
Pakati pekugadziriswa kweamniotic fluid - kuburitsa uye kudzivirirwa pane zvinokuvadza zvinogona kuitika, kubatsira mukugadzirisa kwemasabhaini pakati peamai nevana, mwana wezvokudya, oxygen ekuendesa.
Uye pakuberekwa, amniotic fluid inobatsira pakuzarura chivharox, kuita se hydraulic wedge uye "ramming" nzira yokuti mwana abve.
Kuongorora kwe amniotic fluid
Mune zvimwe zviitiko, vanachiremba vanotumira mukadzi ane pamuviri kuenda kumamniotic fluid kudya kuti aongorore. Iyi nzira inonzi amniocentesis uye inosanganisira kuvhara kwechidimbu.
Pakati pezviratidzo zve amniocentesis:
- Rhesus-kukakavara pakati peamai nemwana;
- kunyunyuta kwechromosomal pathologies;
- unofungidzira hypoxia (oxygen nzara) ye fetus;
- kana zvikadiwa zvekutanga kutora, amniocentesis inobatsira kuziva kuti kugadzirira kwemapapu emucheche ekuberekwa.
Kuongorora amniotic fluid inobvumira kuziva zvepabonde hwemwana anouya , boka reropa rake, zvirwere zvingangodaro zvinotambura. Asi kuongororwa uku kunogona kungoitwa kubva muvhiki 14 yekutakura.
Izvo zvisingawanzoitiki, asi zvinoitika pakati pevakadzi vane pamuviri sehutachiona se embolism neamniotic fluid ( embolism ye amniotic fluid ). Izvi zvinoitika apo inonaya inopinda muropa raamai uye inokonzera kupisa kwemapazi emushonga wemapurmonary yemukadzi. Muna 70-90% yezviitiko zvinopera mumugumisiro unouraya. Nenzira yakanaka, chiitiko chakadaro chinowanikwa muna 1 kubva 20-30 000 genera.
