Phakathi nesikhathi sonke sokukhulelwa, i-fetus isemvelo yasemanzini - yisigqila esigcwele amniotic fluid, kuthiwa yi- amniotic fluid . Kuze kube yisikhathi sokuzalwa, le bubble yenza imisebenzi eminingi - inciphisa ukuzamazama komhlaba, iqhaza ezinkambisweni ze-metabolic fetal, inikeza ukulungiswa kokusebenza okujwayelekile kwezitho ezintsha. Lapho isikhathi sokubeletha siyeza, isisu sifana - futhi wonke amniotic fluid aphuma - le nqubo ibizwa ngokuthi "ukugeleza kwamanzi".
Mayelana nenombolo yamniotic fluid futhi evamile
Nge-ultrasound ehleliwe, udokotela uhlola ngempela inani le-amniotic fluid, aliqhathanisa nesilinganiso sokukhulelwa okunikeziwe futhi aqaphe izinguquko ezingenzeka ekubunjweni kwawo. Isimiso nesilinganiso samanzi amniotic zibalwe isikhathi ngasinye sokubeletha futhi zihanjiswa etafuleni elingezansi:
Idatha enikeziwe etafuleni iyalinganiselwa, ngoba udokotela uhlola ngokuqondile lesi sibonakaliso ngesikhathi se-ultrasound, ucabangela isimo esiphelele sowesifazane okhulelwe nazo zonke izinkomba zezempilo zakhe kanye nosana esibelethweni. Inani lama-amniotic fluid lihluka kakhulu futhi okujwayelekile kulokhu kuyisikhathi esilandelayo. Itafula linikeza kuphela umqondo wemikhawulo yesimiso se-amniotic fluid, ngakho-ke ukuxilongwa kokugcina kwenziwa kuphela udokotela osekelwe ku-ultrasound.
Umkhuba we-amniotic fluid ungenye yezimiso ezibaluleke kakhulu ezithintekayo, ngoba le nkomba iyimpawu ezithembekile ze-pathology of pregnancy. Lapho ukusebenza kwezitho zangasese zomntwana kuphazanyiswa, ama-polyhydramnios ajwayele ukubhekwa, ne-pathology engxenyeni yomzimba kamama - kaningi kukhona ukungondleki. I-Mnogovody kwabesifazane abakhulelwe bacabangela inkomba enjalo ye-amniotic fluid, engaphezu kwesimiso (kulokhu - umkhawulo ongaphezulu webanga) ngezikhathi ezingu-1.3-1.5. Ukungondleki (i-quarter engaphansi komkhawulo ophansi wendabuko) ugcwele ukubeletha okunzima nokuhlukunyezwa kwengane. Ama-Polyhydramnios ayingozi njengosongo lokukhulelwa kwesibeletho nokusakaza kwe-fetus.
