Ukulimala kwe-CNS kwiintsana ezisanda kuzalwa kukuphulwa kwegazi kwiingqondo, ngenxa yoko ingqondo engayifumani imfuno efunekayo yegazi, kwaye ngenxa yoko, ayikho i-oxygen kunye nezondlo.
Hypoxia ingaba:
- imvelaphi yokuzalwa komzimba ehlobene nokukhulelwa kunye nenkqubo yokunikezelwa;
- i-etiology emva kokuzalwa, eyavela emva kokuzalwa komntwana.
Phakathi kwezinto ezibangela umonakalo kwinkqubo yesiseko yomnyo, i-hypoxia yindawo yokuqala. Kwiimeko ezinjalo, iingcali zithetha ngezilonda ze-hypocox-ischemic zesimiso se-nervous central in the newborns.
Ukulimala kwe-hypoinic-ischemic ye-system central neervous system
Iziphumo ezinobungozi emntwaneni zingabangela izifo ezinzima kunye nezifo ezingapheliyo zomama, zisebenza kumashishini anobungozi (iikhemikhali, imirhumo eyahlukeneyo), imichimo emibi yabazali (ukutshaya, ukusela utywala, ukutshaya iziyobisi). Kwakhona, iziphumo ezinobungozi ezinobungozi kumntwana okhulayo kwisibeleko somntwana zibangelwa yi-toxicosis enamandla, ukungena kwintsholongwane kunye ne-patcental pathology.
Ukulimala kwe-hypocinic-ischemic ye-nervous system
Ngexesha lomsebenzi umntwana usenomdla obalulekileyo emzimbeni. Iimvavanyo ezinzulu kakhulu kufuneka zifumaneke ngumntwana, ukuba inkqubo yokuzalwa idlula ngokubeleka: ukubeletha kwangaphambi komntwana okanye ukukhulelwa, ukungabikho kobukhokho, ukukhulelwa kwangaphambili kwe-amniotic fluid, fetus enkulu, njl.
Iziganga ze-cerebral ischemia
Kukho imilinganiselo emithathu yomonakalo we-hypoxis:
- Isilonda se-hypoxic of system central nervous of 1 degree. Esi sigaba esilula kakhulu sibonakala ngokuvuya okanye ukudandatheka kwiveki yokuqala yobomi bentsana.
- Isilonda se-hypoxic of system central nervous of degree 2. Ngomlwelwe wokukhawulelana ngokwemilinganiselo, ixesha elide lokukhubazeka liyabonwa, ngokuthintela.
- Isilonda se-hypoxic of system central nervous of degree. Kwimeko enzima, umntwana uhlala kwiyunithi yonyango enzulu , apho kunikezelwa unyango olunzulu, njengoko kukho ingozi enkulu kwimpilo nobomi bentsana.
Iziphumo zengozi ye-hypoxischemical ye-nervous system
Ngenxa ye-hypoxia, i-reflexes yokuzalwa komntwana inokuphazamiseka, ukuphazamiseka kokusebenza kwenkqubo ye-nervous central, intliziyo, imiphunga, iintso kunye nesibindi kunokwenzeka. Kamva, kukho ukulibaziseka kwimizimba kunye
Ngokumalunga nalokhu, abafazi bayacetyiswa ukuba bathathe iirekhodi zezokwelapha ngaphambi kokukhulelwa, babe nokuhlolwa kweemviwo ngexesha elifanelekileyo, baholele indlela yokuphila enempilo ngexesha lokulungiselela ukukhulelwa kunye nokukhulelwa. Ukuze unyango olusebenzayo, i-cerebral ischemia kufuneka ifumaneke kwiinyanga zokuqala zobomi bentsana.
