Tshwj xeeb tshaj yog nws txhawj xeeb xws li qhov qhia tau tias qhov nyiaj ntawm amniotic kua. Feem ntau, qhov kev xeeb tub ntawm amniotic kua yuav tsum yog tsawg kawg 500 thiab tsis pub tshaj 2000 ml.
Ntawm chav kawm, thaum nws ntxov hnub nws tsuas yog 30 ml, tab sis ze zog mus rau 37 lub lim piam, lub ntim ncav nws cov nqi siab ntawm 1500 ml. Kaw rau kev yug me nyuam, qhov ntim no txo rau li ntawm 800 ml. Cov dej ntawm amniotic kua dej kuj hloov.

Ntawm chav kawm, dej ntxuav tawm - txog txhua 3 xuab moos, lawv raug kho tshiab.
Kev ua haujlwm ntawm amniotic kua
Ntawm qhov teem caij ntawm amniotic kua - amortization thiab tiv thaiv kev raug mob, pab nyob rau hauv tus txheej txheem ntawm metabolism hauv niam thiab me nyuam, tus me nyuam noj, cov pa oxygen.

Ntawm cov kev taw qhia rau amniocentesis:
- Rhesus-tsis sib haum xeeb ntawm niam thiab me nyuam;

- xav tias hypoxia (oxygen starvation) ntawm tus me nyuam hauv plab;
- thaum muaj menyuam yaus thaum ntxov, amniocentesis pab nrhiav kom paub qhov kev npaj ntawm tus menyuam hauv plab rau kev yug menyuam.
Txoj kev tshawb no ntawm amniotic kua muaj peev xwm paub txog kev sib deev ntawm tus me nyuam yav tom ntej , nws cov ntshav pawg, cov kab mob ntawm cov tsiaj nyeg. Tab sis qhov kev tsom xam no tsuas yog nqa tawm ntawm lub 14th lub lim tiam ntawm cev xeeb tub.
