Ubuchopho hypoxia

ubuchopho hypoxia kwenzeka endabeni i Ukushoda okukhulu komoya-mpilo. Lokhu lula okuthonywa nayizimo zendawo noma izifo kubantu.

Ukweleta imvelaphi yayo hypoxia kuphazamiseka cerebral kwegazi, uthi ukushaqeka, ukwehluleka oyingozi zenhliziyo, ubuthi by-carbon monoxide, inani transverse inhliziyo ukuvinjelwa asphyxia yinto ehlukile. Oxygen yokulamba zobuchopho kungase kube ngenxa yobunzima phakathi nokuhlinzwa kwakhe enhliziyweni nezitsha omkhulu, futhi kungenza ukuzibonakalisa ngasekuqaleni isikhathi nasezinkingeni ezilandela ngemva kokuhlinzwa. Kulesi simo, kukhona ukuthuthukiswa ezihlukahlukene syndromes zezinzwa zengqondo.

Brain hypoxia: izimpawu

Ekuqaleni, kukhona ukwephulwa microvasculature, okuyinto ziyabonakala ukuthuthukiswa stasis, plasmatic impregnation futhi necrobiotic izinguquko semithambo izindonga nge ukwephulwa permeability. Kungenzeka futhi ukuphuma plasma pericapillary isikhala. Ifomu acute lesi sifo ephelezelwa degrees ezehlukene nolokubhujiswa neurocytes. Amaseli zobuchopho ibhekane vacuolization, chromolysis, giperhromatoz, pycnosis, ukuvuvukala oyingozi futhi homogenizing izinzwa ischemic. Nhlobo wephule ultrastructure we-nucleus futhi ulwelwesi yayo, wathi ekubhujisweni mitochondrial.

hypoxia olunamandla zobuchopho kuzibonakalisa ngesimo excitation isimiso sezinzwa, okuyinto esikhundleni braking nokucindezela okwandayo of ukusebenza yayo. Ukuyaluza, bajabula, kwenhliziyo kanye ukuphefumula, isikhumba ugodo, izithukuthuku ebandayo ephelezelwa izimpawu engqondo. inkathi excitation kungaba lingekho. Lokhu kuhlola kulandelwa isimo evilaphayo nge ugesi wawuphela, isiyezi, ukozela, ukucobeka jikelele, ethukile, ukucindezelwa kancane kancane ukwazi.

Isikhathi sokukhululwa lokungeniswa inzuzo umsebenzi subcortical esihambisana disordered motor umsebenzi, Ukudlikizela, kulandele ukulahlekelwa ingqondo isikhumba, periosteal, umsipha. Ngesikhathi ijika elilandela zesifo zinyamalale corneal ikhaliphe pupillary. ukukhubazeka spastic nokukhuphula imisipha ithoni, ikhaliphe elichaza ukubonakaliswa sokugembula motor umsebenzi.

Hypoxia zobuchopho nge ukuthuthukiswa ngokushesha ngomzuzu wawo olandelayo kubangela nokulahlekelwa ukwazi. Kuthatha imizuzu embalwa - nomuntu iwela equlekile. ubuchopho hypoxia kubangela ezihlukahlukene syndromes zezinzwa.

Kukhona amafomu alandelayo ka ikhoma: subcortical (isimo decortication) perednestvolovaya (diencephalic, mesencephalic) zadnestvolovaya futhi esibulalayo (ezimba). Ukuqala Kwenkathi ikhoma ngokuvamile kwandulelwe r. N. isimo prekomatosnoe: stupor (stupor), emangalisa kanye somnolence (ukozela).

Phakathi syndromes organic lesion ngokukhukhumala kwentamo isehlane posthypoxic esindayo encephalopathy futhi ngokulinganisela uzwakalise posthypoxic encephalopathy.

uthi Asthenic kukhona asthenia posthypoxic nge Hypo futhi hypersthenes.

Hypoxia zobuchopho: ukuphathwa

Lapho ukwelashwa kuyadingeka ukuze balondoloze ukusebenza isimo senhliziyo, ukuphefumula, uketshezi electrolyte ibhalansi, acid-base isiguli. Imiphumela hypoxia kwegazi iphathwa izidakamizwa, neuroleptics. indima Special cerebral hypothermia extracorporeal kwegazi futhi oxygenation giperboricheskoy. Antioagulyanty reopoligljukin futhi nomthelela nokuvimbela ukuphazamiseka microcirculation. Protivogipoksichesie mithi ngempumelelo ngokwanele. Ososayensi baye wadala quinones entsha, okuncike ortobenzohinon. Gutimine, sodium hydroxybutyrate, amaqembu nootropics praparaty ifa izakhiwo zokuzivikela.
