I loko o ka'ōpū o kāna'ōpū (me kahi o kona mau lā mua loa), ua hoʻopuniʻia ka'ōpū e ka wai o ka amniotic, a me ka wai o ka manawa. ʻO kēia wahi, kahi e hoʻokuʻu ai ke pēpē, e like me ke kanaka kōkua ma kahi ākea,ʻaʻole ia e pale aku iā ia mai nā hana o waho a mālama i ka mahana kūpono, akā e komo pū nō hoʻi i loko o ka hanu. ʻO ka nui o ka wai amniotic noʻeiwa mau mahina e hoʻololi mau ana, akā, no kēlā me kēia manawa o ka hāpaiʻana, aia nāʻano o ka nui o ka wai o ka wailele. Hiki ke hoʻohālikelike i loko o kahi alakaʻi a iʻole kekahi mea keʻanoʻole ka hua.
ʻO ke kumu maʻamau o ka wai amniotic i ka wā o ka hāpaiʻana
ʻO ka nui o ka wai amniotic e hiki ke 600-1500 ml. ʻO ka nui o ka wai amniotic e emi iho i ka 500 ml ka mea he hauʻoli,ʻoi aku ka nui o ka 1,5-2 lita i polyhydramnios. Hiki ke kōkua ka ultrasound i ka hōʻoia pololei.
I ka manawa o ke kaʻina hana ultrasound, ua hoʻoholo ka meaʻikeʻike i ka nui o ka wai ma o kaʻikeʻana i ka huli. Inā loaʻa he wai nui o ka wailele amniotic,ʻikeʻia nā polyhydramnios, inā heʻuʻuku - wai. Ma ka hōʻoleʻana i ke kūlana maʻamau, ua hana ke kauka i kahi noiʻi maikaʻi loa - e helu ana i ka helu kuhikuhi o ka wai o ka wailele. No kēia mea, ua māhele likeʻia ka mākia uterine i 4 mau'āpana like me nā lainaʻelua, aʻo kekahi o ia e hele pololei ana i ka'ākau, ma ka laina keʻokeʻo o ka'ōpū, aʻo kekahi - ma waho o ka pae kiʻekiʻe. Ma kēlā me kēiaʻaoʻao, ua anaʻia ka poʻomanaʻoʻoi loa o ka pocket (kahi kūpono ma waena o ka pāpani me ke kumukū), ua hōʻuluʻuluʻia nā hualoaʻa, e hāʻawi ana i ka hōʻailona o ka waiwai amniotic.
No kēlā me kēia wā o ka hāpaiʻana, aia nā maʻamau o kēia hōʻike. Eia kekahi laʻana, heʻano maʻamau ka helu o ka wai o ka wailele me ka manawa o 22 wiki o ka 14.5 cm, aiʻole 145 mm (hiki i nā loli ke kūpono i loko o kahi āpau o 89-235 mm). A i nā hebedoma he 32, e 144 mm ka helu o ka wai o ka wailele me ka halaʻana o ka 77-269 mm. ʻO nā kumukūʻai no nāʻano likeʻole o ka'ōpū ke loaʻa ma ka papa kuhikuhi o ka index index fluid .
Nā hua'ōlelo palewai maʻamau - nā meaʻino
E pili ana i nā kuhiʻana o ka mea maʻamau i'ōleloʻia i ka hopena o ka helu o ka wai amniotic i lalo aʻoi paha iʻoi aʻe ma mua o ka hōʻikeʻia ma nā koina papa. ʻO nā polyhydramnios a me nā oligohydramnios e hōʻike i nā maʻi o ka hoʻouluʻana o ke keiki hānai a i ka wā o ka hāpaiʻana.
I ka wā o polyhydramnios, noho mau ka keiki i kahi kūpono i loko o ka'ōpū, ai kekahi mau manawa e huli a puni i ke kaula umbilical. Hiki i ka wai o ka wai paila i ka hoʻonāukiuki i mua o ka hānauʻana a me ka hānau hānau. ʻO ka nui o ka pūpū o ka'ōpū kaʻoi aku o kaʻoi aku i ka laweʻana a ma ka wā o ka post post, kahi e hiki ai i ka nāwaliwali o ka hana a me ka uluʻana o ka kahe.
ʻO nā kumu nui o nā polyhydramnios:
- nā malupalu (o nā'ōpiopio) a me nā meaʻinoʻole o ka'ōpiopio chromosomal;
- ka lawaʻole o ka hemoʻana;
- ka'ōpū ma muli o ka rhesus-conflict;
- maʻiʻeha o ka wahine hānau;
- ʻo ka maʻi diabetes i loko o nā wāhine hāpai.
Inā hōʻike ka helu kuhikuhi o ka wai ākea i ka nele o ka wai i ka lua o ka manawa o ka hāpaiʻana, a laila e hiki mai paha kahi hopena weliweli-ka hoʻopiʻiʻana o ke kaula o ka umbilical. Eia kekahi, ua hopuʻia ke keiki i loko o ka pūpū, ua kaupalenaʻia kāna mau hana. Hiki i nā pēpē ke loaʻa i nā pilikia me nā huila o ka huela a me ka hiwi ma hope o ka hānauʻana.
ʻO ka uluʻana i kaʻaiʻole ka mea hikiʻole ke alakaʻi i:
- nā pōʻino o ka'ōpiopio (ka pūnaha hoʻonāukiuki a me nā puʻupaʻa);
- hypoxia a me ka hypotrophy fetal;
- ka lawaʻole o ka hemoʻana;
- ka wā hānau ma mua;
- maʻi maʻi;
- maʻi nui o ka mea hāpai;
- ka pume.
Ma keʻano likeʻole i ka manaʻo o kekahi mau wāhine,ʻo ka nui o ka wai wai e inu ai lākouʻaʻole ia e hoʻololi i ka loli o ka nui o ka wai amniotic i ka placenta.
