I-Cerebral anoxia: yintoni, iimpawu kunye nokuba lwenziwa njani unyango

Umxholo

• Iimpawu ze-anoxia yobuchopho
• Unyango lwenziwa njani

I-Cerebral anoxia yimeko ebonakaliswa kukunqongophala kweoksijini kwingqondo, enokuthi ikhokelele ekufeni kwee-neurons kwaye ibangele ukonakala kwengqondo okungaguqukiyo. I-Anoxia inokwenzeka ngenxa yokopha okanye ukubanjwa kokuphefumla, umzekelo, kwaye ixesha elide ingqondo ihamba ngaphandle kweoksijini, iziphumo ezibi kakhulu.

Ubungakanani bokwenzakala kukwanxulumene nommandla wengqondo ongenakho ukubonelela ngeoksijini. Njengoko inkqubo ye-nervous central ingazukuphinda ihlaziye, izilonda zinokuhlala ngokusisigxina.

Iimpawu ze-anoxia yobuchopho

Ngenxa yokunqongophala kweoksijini kwingqondo, iiseli ze-neuronal ziqala ukufa, ezinokukhokelela ekonakaleni kwengqondo okungalungisekiyo, ezinokukhokelela kwi-coma kunye nokufa kwengqondo. Ixesha elide ingqondo ihamba ngaphandle kweoksijini, imiphumo iba mibi kakhulu. Ke ngoko, kubalulekile ukuba uqaphele imiqondiso ebonisa i-cerexal anoxia:

• Ukunyuka kwentliziyo;
• Ubunzima bokuphefumla;
• Ukuphulukana nengqondo;
• Isiyezi;
• Ukudideka kwengqondo;
• Umbala oluhlaza okwesibhakabhaka wemilebe okanye iinzipho;
• Iinyikima;
• Ukungabikho zingqondweni.

I-Cerebral anoxia inokwenzeka kwakamsinya emva kokuzalwa, ibe sesinye sezizathu eziphambili zokuba ne-asphyxia ye-neonatal. Ukunqongophala kweoksijini kwingqondo kunokwenzeka nakubantu abadala, ngakumbi abo basemngciphekweni omkhulu wokuhlaselwa sisifo sentliziyo okanye ukubetha. Jonga indlela yokuchonga nokunyanga ukubetha.

Unyango lwenziwa njani

Eyona njongo iphambili yonyango lwe-anoxia yecerebria kukubuyisela amanqanaba eoksijini kwingqondo. Ukongeza, kwenziwe uphando oluninzi ngeeseli ze-embryonic stem kwaye zibanga ukuba kunokwenzeka ukubuyisa ezinye zeziphumo ze-anoxia yecerebral, nangona kunjalo kusaqhubeka ukuqhubekeka kunyango lwe-embryonic stem cell ukuze ibe lolunye uhlobo lwemeko. Jonga ukuba unyango lwenziwa njani ngeeseli zeziqu.
