He aha ka surfactant pulmonary a pehea e hana ai

Anter

• Nā hana a ka surfactant
• He aha ke kumu o ka nele o ka surfactant

ʻO ka surfactant pulmonary kahi wai i hana ʻia e ke kino i loaʻa ka hana o ke kōkua ʻana i ka hoʻololi o nā kino hanu i nā akemāmā. Hāʻawi kāna hana i ka alveoli pulmonary, he mau ʻeke liʻiliʻi ia e pili ana i ka hoʻololi kinoea, e hāmama i ka wā e hanu ai, ma o ka hoʻoluhi, e kōkua ai i ke komo ʻana o ka oxygen i loko o ke kahe o ke koko.

ʻAʻole hiki i nā keiki hānau ʻōpio ke lawa pono ka hana ʻana o ka surfactive pulmonary e hōʻoia i ka hanu maikaʻi ʻana a, no laila, hiki ke hoʻomohala i ka maʻi hanu pēpē pēpē, e pilikia ana i ka hanu ʻana.

ʻO ka mea pōmaikaʻi, aia kekahi lāʻau lapaʻau, ʻo ia ka surfactant exogenous, nāna e hoʻohālike i ke kino maoli o ke kino, a kōkua i ka hanu ʻana o ka pēpē a hiki i kona hiki ke hana ponoʻī. Hiki ke mālama ʻia kēia lāʻau i ka hola mua ma hope o ka hānau ʻia ʻana o ka pēpē, no ka hopena wikiwiki, ma o kahi ʻōmole pono i nā akemāmā.

Nā hana a ka surfactant

ʻO ka hana nui o ka surfactant pulmonary e hana i kahi papa kiʻi ʻoniʻoni e ʻae ai i ka wehe kūpono o ka alveoli pulmonary a ʻae i ka hanu ʻana, ma o:

• Ka mālama ʻana i ka wehe ʻana o ka alveoli;
• E hoʻemi i ka ikaika e pono ai ka hoʻonui ʻana o nā akemāmā;
• Ke kūpaʻa ʻana o ka nui o ka alveoli.

I kēia ala, ʻeleu mau nā māmā a hiki ke hoʻokō pono i nā hoʻololi ʻōpena.

He aha ke kumu o ka nele o ka surfactant

Hana ʻia ka surfactant i ka wā o ke kō ʻana o nā māmā o ka pēpē, aia nō i ka ʻōpū o ka makuahine, ma hope o 28 mau pule. No laila, ʻo nā pēpē maʻa mau i hānau ʻia ma mua o kēia wā, ʻaʻole lawa paha ka hana ʻana o kēia mea, a he kumu ia no ka maʻi ʻōpū o ke pēpē.

ʻO kēia maʻi, i ʻike ʻia ʻo ka hyaline membrane Syndrome a i ʻole ka respiratory depression syndrome, ke kumu o ka paʻakikī i ka hanu ʻana, ka hanu wikiwiki ʻana, ka hū ʻana a me nā lehelehe polū a me nā manamana lima, a he mea make paha ia.

I kēia mau hihia, hiki i ka pediatrician ke hōʻike i ka mahele o ka exogenous surfactant i ke keiki hānau hou, i hiki ke kūlohelohe, i unuhi ʻia mai nā holoholona, ​​a i ʻole synthetic, i hiki ke pani i ka hana o ka surfactant i hua ʻia i nā ake māmā a ʻae i ka hanu kūpono. E aʻo hou aʻe e pili ana i nā hōʻailona a pehea e mālama ai i ka maʻi hanu hanu kamaliʻi.
