Amniotic uketshezi

I-Amniotic fluid iwuketshezi olucacile, olunombala ophuzi ozungeze umntwana ongakazalwa (umbungu) ngesikhathi sokukhulelwa. Iqukethwe esikhwameni se-amniotic.

Ngesikhathi isesibelethweni, ingane intanta ku-amniotic fluid. Inani le-amniotic fluid likhulu kakhulu cishe emavikini angama-34 (ukukhulelwa) ekukhulelweni, lapho lilinganiselwa ku-800 mL. Cishe ama-600 ml we-amniotic fluid azungeze ingane ngesikhathi esigcwele (ukukhulelwa kwamasonto angama-40).

Uketshezi lwe-amniotic luhlala luhamba (lujikeleza) lapho ingane igwinya futhi "idonsa" uketshezi, bese luyidedela.

I-amniotic fluid iyasiza:

• Ingane ekhulayo inyakaze esibelethweni, evumela ukukhula kwamathambo okufanele
• Amaphaphu akhula kahle
• Ivimbela ingcindezi entanjeni
  
• Gcina izinga lokushisa elizungeze ingane njalo, livikele ekulahlekelweni ukushisa
• Vikela ingane ekulimaleni ngaphandle ngokuvimba ukushaywa okungazelelwe noma ukunyakaza

Uketshezi oluningi lwe-amniotic lubizwa nge-polyhydramnios. Lesi simo singenzeka ngokukhulelwa okuningi (amawele noma amawele amathathu), iziphambeko zokuzalwa (izinkinga ezikhona lapho ingane izalwa), noma isifo sikashukela sokukhulelwa.

I-amniotic fluid encane kakhulu yaziwa njenge-oligohydramnios. Lesi simo singenzeka ngokukhulelwa sekwephuzile, ulwelwesi oluqhekekile, ukungasebenzi kahle kweplacenta, noma ukungajwayelekile kombungu.

Inani elingajwayelekile le-amniotic fluid lingadala ukuthi umhlinzeki wezokunakekelwa kwezempilo abuke ukukhulelwa ngokucophelela. Ukususa isampula loketshezi ngokusebenzisa i-amniocentesis kunganikeza imininingwane ngocansi, impilo, kanye nokukhula kombungu.
