ʻO ka placenta ka mea nui loa i ka wā e hāpai ai, a laila e hilinaʻi - pehea e hāʻawiʻia mai ai ka'ōpū me ka oxygen a me nā meaʻai. Nui nā kumu e hoʻopili i ka pololei o ka hoʻokumuʻana o placenta: nā maʻi viral i ka wā o ka hāpaiʻana, ke kūʻana o nā maʻi maʻamau, Rh-conflict, nā hanaʻino a me nā mea'ē aʻe. ʻO ka uluʻana o ka placenta e hoʻomau mau i nā hebedoma 37, ma ka hopena o ka'ōpū e hiki ke liʻiliʻi. ʻO ke kumu o ka placenta ke hoʻoholoʻia wale nō e ka ultrasound.
Pehea e hoʻoholo ai i ka lahilahi o ka placenta?
Ke anaʻia ka mānoanoa o ka placenta e ke kahawai kiʻi no ka wahi nui loa. Ma keʻano o ka mānoanoa o ka placenta, hiki i kekahi ke helu i konaʻano a me ka pono o kāna mau hana. No laila, hiki i ka lahilahi o ka placenta ke kamaʻilio e pili ana i ka placenta, maʻi, rhesus conflict, ka maʻi diabetes a me anemia. Pono e hoʻopaʻa ponoʻia kēlā wahine i kahi wahine hānai wahine a nānāʻia no nā maʻi kūikawā a me nā maʻi. Hiki i nā'ōlohelohe o ka placenta a me kona lahilahi paha, ke kamaʻilio pū paha no ka nohoʻana o nā maʻi maʻi i loko o ka wahine hānau (ʻo ka hemahema paha o nā mea maʻi maʻamau). Ma nā hihiaʻelua,ʻaʻole hiki i ka placenta ke hana pono i nā hana o ka hāʻawiʻana i ka oxygen a me nā meaʻai.
Nā kūlana maʻamau o kaʻeleʻele placental no nā pule
E noʻonoʻo i ka manawa o ka hāpaiʻana i ka nui o ka mānoanoa o ka placenta.
I ka manawa hānai i nā hebedoma 20, he 20 mm mau ka lahilahi o ka placenta. Ma nā kūlana o ka 21 a me ka 22 pule -ʻo ka mānoanoa maʻamau o ka placenta e like me 21 a me 21 mm, kekahi. ʻO ka mānoanoa o ka placenta 28 mm e like me ka 27 o ka hebedoma o ka hāpaiʻana.
ʻO ka mānoanoa o ka placenta ma 31, 32 a me 33 mau wiki o ka hanaʻana e like me ka 31, 32 a me 33 mm. ʻO kaʻili ikiʻana mai nāʻike maʻamauʻole he kumu ia e hopohopo ai. Inā he mea nui ka haʻaluluʻana o ka maʻamau, a laila ua'ōlelo houʻia ka hōʻoiaʻana o ka ultrasound diagnorography, cardpletography a me ka cardiotography. Inā pono ka maʻi o ke keiki,ʻaʻole pono ka lāʻau lapaʻau.
ʻO kēlā me kēia manawa'ōpū e pili ana i kekahi mau palena o ke kūlana maʻamau ma keʻano o ka mānoanoa o ka placenta. Aʻo ke kauka nāna e nānā i ka wahine hāpai, i kaʻikeʻana i ka loli o ka mānoanoa o ka placenta e pili ana i nā hualoaʻa o ultrasound, e hāʻawi pono i kona mauʻano o ka hoʻokolokoloʻana e hoʻoholo i nāʻano o ka lāʻau.
