Amniotic fluid

Amniotic fluid lulwelo olucacileyo, olunetyheli olujikeleze usana olungekazalwa (olungekazalwa) ngexa lokukhulelwa. Iqulethwe kwingxowa ye-amniotic.

Ngexa lisesibelekweni, usana ludada kulwelo olunama-amniotic. Isixa se-amniotic fluid sikhulu kakhulu malunga neeveki ezingama-34 (ukumitha) ekukhulelweni, xa ifikelela kwi-800 mL. Malunga ne-600 mL ye-amniotic fluid ejikeleze usana ixesha elipheleleyo (iiveki ezingama-40 zokumitha).

Ulwelo lwe-amniotic luhlala luhamba (lujikeleza) njengokuba umntwana eginya kwaye "ephefumlela" ulwelo, emva koko alukhuphe.

Amniotic fluid inceda:

• Umntwana osakhulayo ukuba ahambe esibelekweni, nto leyo evumela ukukhula kwethambo elifanelekileyo
• Imiphunga ikhula kakuhle
• Ukuthintela uxinzelelo kwintambo
  
• Gcina ubushushu obujikeleze usana, ukhusele ekuphulukaneni nobushushu
• Khusela umntwana ekonzakaleni kwangaphandle ngokuthintela ukubethwa ngesiquphe okanye iintshukumo

Amniotic fluid kakhulu abizwa ngokuba yi-polyhydramnios. Le meko inokwenzeka ngokukhulelwa okuninzi (amawele okanye amawele amathathu), ukungafani komzimba (iingxaki ezikhoyo xa umntwana ezalwa), okanye isifo seswekile sokukhulelwa.

Amanzi amancinci amancinci abizwa ngokuba yi-oligohydramnios. Le meko inokwenzeka xa ukhulelwe kade, inwebu eqhekekileyo, ukungasebenzi kakuhle kweplastikhi, okanye ukungaqheleki komntwana.

Amanani angaqhelekanga e-amniotic fluid anokubangela umboneleli wezempilo ukuba abukele ukukhulelwa ngononophelo. Ukususa isampulu yolwelo nge-amniocentesis kunokubonelela ngolwazi malunga nesini, impilo kunye nokukhula komntwana.
