ʻO kaʻoiaʻiʻoʻaʻole nā mea a pau i kūpono me ka placenta, nā makuahine o ka wā e hiki mai ana, ma keʻano he kūlana, eʻike i ka nānāʻana o ke kaha kiʻi. ʻO ka hōʻailona maʻamau ka uluʻana o ka placenta. E hoʻomaopopo mākou, ma mua o ka pāʻaniʻana o ka placenta, no ke aha e ulu ai kēia maʻi a pehea e hoʻopauʻia ai.
ʻO ka'ōpū o ka Placenta - Nā kumu
ʻO ke kumu nui o ka uluʻana o ka placentaʻo ia ka'ōmakule. I loko o ka'ōpū, hanaʻia ka placenta ma nā haʻawina e pili nei: ka hoʻolālā (i ka 16 mau wiki), ke uluʻana, ke kūlana makua a me kaʻelemakule. Loaʻa i nā kūlana kiʻekiʻe o ka placenta :
- ke kaʻina koho (hiki i ka 30 mau wiki) - like keʻano o ka hale placental;
- ke kēkelē mua (27-34 mau hebedoma) - e lilo i ka'āpana o ka placenta i kahi liʻiliʻi iki, eʻikeʻia nā waihona o nāʻene calcium;
- ka lua o ke kula (34-39 mau wiki) - "haʻaheo" a piʻi ka helu o nā helu;
- ke kolu o ka dipie (37 mau pule) - kahi lobular o ka placental, nā kikowaena nui loa.
ʻO kēlā me kēia helu o ke kūlana kūpono e pili ana i kahi mānoanoa o ka placenta. Inā hoʻoholoʻia ka ultrasound e kekahi'āpana haʻahaʻa,ʻo ia hoʻi,ʻaʻole hiki i kahi o ke keiki ke hana hou i kāna mauʻoihana. Eia nō naʻe, he kumu'ē aʻe ka hopena o ka placenta:
- ʻo ka placenta heʻoi aku ka māmā ma mua o ka maʻamau i nā hihia o ka'ōpū hanuʻana ma o ka Rh-kūpaʻa aiʻole ka maʻi lele;
- hoʻopau i ka momona o ka placenta (ke ulu nui a hoʻoulu i ka hapa nui o ka ma loko o ka pūpū) keʻikeʻia inā he diabetes ka mea maʻi;
- ʻo ka'ōpū lahilahi ma ka hāpaiʻana, he hōʻailona ia i ka maʻi o ka makuahine e kali nei;
- hiki ke mālamaʻia ka māmā o ka placenta i ka wā o ke kōkō me ka haʻalulu placental, gestosis a me nā hāpai houʻana.
He aha ka pōʻino e lahilahi ai ka placenta?
No ka hiki ole i ka placenta momona ke pale i kāna mau hana, loaʻa i ka pēpē ka lawaʻole o ka oxygen a me ka meaʻai. ʻO kēia ke alakaʻiʻana i ka hypoxia fetal, ka lōʻihi o kona ulu a me kona uluʻana. Eia kekahi, he mea weliweli paha ka hoʻopauʻana i ka hāpaiʻana, a ma nā hihia kūpono paha, hiki i ke keiki ke make ma mua o ka hānauʻana.
ʻO ka māmā o ka placenta - ka lāʻau
Inā hōʻike ka mea ultrasound i kahi placenta nui , e kau hou ke kauka i nā haʻawina hou: kāpikipikōʻau, dopplerometry a me nā ho'āʻo hormone.
ʻO ka kumu nui o ka mālamaʻana,ʻo ia ka hoʻopauʻana i ke kumu o ka māhuahua o ka placenta. Eia kekahi,ʻo nā wāhine hāpai ke kauʻia i ka lāʻau a hoʻomākaukau no ka hoʻomaʻemaʻeʻana i ka hypoxia a me ka mokupoko hypotrophy: Kurantil, Vktovegin, Essentiale, a me nā mea'ē aʻe.
