I-Amniotic fluid okanye i-amniotic fluid yindawo yokuphila emanzini ejikeleze umntwana ukususela ekukhulelwe kwangaphambili kuze kube sexesha lokuziswa. Kule ndawo, umntwana ukhululekile kokubambisa nokushisa. Umbane ukhusela ukuxhatshazwa kwemishini, uyondla, inika umxholo wokhuseleko.
Ekubeni i-amniotic fluid idlala indima ebalulekileyo ngexesha lokukhulelwa, oogqirha bayayilinda. Ingakumbi ixhalabisa ngolu hlobo njengesalathisi se-amniotic fluid. Ngokuqhelekileyo, ukukhulelwa kwe-amniotic fluid kufuneka kube ngu-500 kwaye kungabi ngaphezu kwe-2000 ml.
Ngokuqinisekileyo, ngomhla wokuqala ngowama-30 ml kuphela, kodwa ukusondela kwiiveki ezingama-37, umthamo ufikelela kwixabiso eliphakamileyo le-1500 ml. Ngokusondele ekuzaleni, le ndlu iyancipha ukuya kuma-800 ml. Ukubunjwa kwe-amniotic fluid kuyashintsha. Ukuba ekuqaleni kokukhulelwa kufana nesakhiwo kwisiplasma yegazi, ngoko kwimimiselo kamva, iimveliso zobomi bentsana zixutywe apha. Ewe, amanzi ahlambulukileyo - malunga neeyure ezingama-3, ahlaziywa ngokupheleleyo.
Imisebenzi ye-amniotic fluid
Phakathi kokuqeshwa kwe-amniotic fluid-amortization kunye nokukhuselwa kwingozi enokwenzeka, uncedo kwinkqubo yokumisa umzimba phakathi komama nomntwana, isondlo sesondlo, ukuthunyelwa kwe-oxygen.
Kwaye ekuhambeni kokuzala, i-amniotic fluid inceda ekuvuleni umlomo wesibeleko, usebenze njengomgudu we-hydraulic and "ramming" indlela yokuba umntwana aphume.
Uhlalutyo lwe-amniotic fluid
Kwezinye iimeko, oogqirha bathumela owesifazane okhulelweyo ukuba amniotic fluid ayifake ukuhlalutya. Le nqubo ibizwa ngokuba yi-amniocentesis kwaye ibandakanya ukugqitywa kwesibindi.
Phakathi kweziboniso ze-amniocentesis:
- I-Rhesus-imfazwe phakathi koomama nomntwana;
- krokra ye pathologies ye chromosomal;
- krokraza i-hypoxia (i-oxygen starvation) yomntwana;
- Xa kunesidingo sokunikezelwa kwangethuba, i-amniocentesis inceda ekufumaneni ukulungelelaniswa kwemiphunga ye-fetal yokubeleka.
Ukufundwa kwe-amniotic fluid kuvumela ukwazi ngesondo lomntwana ozayo , iqela lakhe legazi, izifo ezithandekayo. Kodwa olu hlalutyo lwenziwa kuphela kwiiveki le-14 lokukhulelwa.
Kuyinto engaqhelekanga kakhulu, kodwa kwenzeka phakathi kwabafazi abakhulelweyo ezifana nokugula njenge-embolism ne-amniotic fluid ( embolism ye-amniotic fluid ). Oku kwenzeka xa uketshezi kungena kwigazi lomama kwaye kuphazamise i-spasm yamasebe omfazi wesifo sompompo. Kwi-70-90% yamatyala iphelela kwisiphumo esibulalayo. Ngethamsanqa, into efana nale iyenzeka kwi-1 ye-20-30 yezigidi zemigangatho.
