• Hawlaha 'surfactant'
• Maxaa sababa la'aanta ah 'surfactant'

Sambabada sambabadu waa dareere uu soo saaro jirka oo leh howsha fududeynta isdhaafsiga gaasaska neefsashada ee sanbabada. Ficilkeedu wuxuu u oggolaanayaa alveoli sambabada, oo ah kiishash yar oo mas'uul ka ah is-weydaarsiga gaaska, inuu sii furnaado inta lagu jiro neefsashada, iyadoo loo marayo xiisad, taas oo sahleysa gelitaanka oksijiinta wareegga dhiigga.

Dhallaanka dhiciska ah ee aan weli gaarin ayaa laga yaabaa inaysan weli yeelan wax soo saar ku filan oo ah sambabada sanbabada si loo hubiyo neefsasho hufan iyo, sidaas darteed, waxaa laga yaabaa inuu yeesho cilladda cilladda neefsashada ee carruurta, taasoo keenta dhibaato daran oo xagga neefsashada ah.

Nasiib wanaagse, waxaa jira daroogo, taas oo ah soo-saare ka-baxsan, oo u ekeysiisa maaddada dabiiciga ah ee jirka, isla markaana ka caawisa neefsashada cunugga illaa uu isagu iskiis u soo saari karo. Daawadan waxaa lagu maamuli karaa saacada ugu horeysa ee ilmuhu dhasho, natiijo dhakhso leh, iyada oo loo maro tuubo si toos ah ugu jirta sambabada.

Hawlaha 'surfactant'

Shaqada ugu weyn ee sambabada sambabadu waa inay samayso lakab filim kaas oo u oggolaanaya furitaanka habboon ee sanbabada sanbabada una oggolaada neefsashada, iyadoo loo marayo:

• Dayactirka furitaanka alveoli;
• Hoos u dhaca xoogga lagama maarmaanka u ah ballaarinta sambabaha;
• Xasilinta cabirka alveoli.

Sidan oo kale, sambabada ayaa had iyo jeer firfircoon oo awood u leh inay si sax ah u wadaagaan is-weydaarsiga gaaska.

Maxaa sababa la'aanta ah 'surfactant'

Wax-soo-saaraha waxaa la soo saaraa inta lagu jiro bislaada sambabaha ilmaha, oo weli ku jira caloosha hooyada, ka dib illaa 28 toddobaad. Sidaa darteed, carruurta dhiciska ah ee dhasha xilligan ka hor, weli ma lahan wax soo saar ku filan oo ah maaddadan, taas oo keenta cilladda neefsashada ee ilmaha.

Cudurkan, oo sidoo kale loo yaqaanno hyaline membrane syndrome ama cilladda neefsashada, wuxuu keenaa dhibaato xagga neefsashada ah, neefsasho deg deg ah, xiiq iyo bushimaha buluuga ah iyo faraha, oo xitaa dilaa ah.

Xaaladahaas oo kale, dhakhtarka carruurtu wuxuu u tilmaami karaa xaddiga wax-ku-oolnimada qalafsan ee ilmaha dhasha ah, taas oo noqon karta mid dabiici ah, oo laga soo saaray xayawaanka, ama la isku soo koobay, taas oo beddeli karta hawsha wax-qabad ee sambabka samaysay oo u oggolaanaysa neefsasho ku filan.
