Sr\u010dani zastoj je nagli prestanak rada srca, koji se \u010desto naziva i klini\u010dka smrt. Ishod je uglavnom smrtan.<\/p>\n

Kada srce prestane da pumpa, prekida se dotok krvi mozgu i ostalim organima. Bez dotoka krvi gubi se kiseonik, bez koga ni jedan organ ne mo\u017ee da funkcioni\u0161e.<\/p>\n

Prekinut dotok kiseonika do mozga mo\u017ee imati katastrofalne posledice. Nakon tri minuta sr\u010danog zastoja javljaju se trajna i nepopravljiva o\u0161te\u0107enja na mozgu, a nakon pet minuta nastupa smrt pacijenta. Pacijent se naj\u010de\u0161\u0107e reanimira spoljnim kompresovanjem srca.<\/p>\n

Sr\u010dani zastoj i sr\u010dani udar su dve razli\u010dite stvari. Za vreme sr\u010danog udara, samo jedna strana srca prestaje da pumpa krv.<\/p>\n

 <\/p>\n

Uzroci<\/strong><\/h2>\n

Sr\u010dani zastoj naj\u010de\u0161\u0107e nastaje kada se javi problem u njegovoj elektri\u010dnoj aktivnosti. To mo\u017ee biti ventrikularna fibrilacija (poreme\u0107aj sr\u010danog ritma) ili asistolija (prekid elektri\u010dne aktivnosti srca). Ventrikularna fibrilacija se \u010desto javlja kod ljudi koji pate od koronarne arterijske bolesti, koja nastaje kao posledica lo\u0161ih \u017eivotnih navika poput pu\u0161enja i gojaznosti. Neki od uzroka ventrikularne fibrilacije mogu biti i strujni udar, davljenje ili pro\u0161irenje srca (dilatirana kardiomiopatija).<\/p>\n

Asistolija predstavlja potpuni prestanak elektri\u010dne i mehani\u010dke aktivnosti srca. Srce prestaje da se kontrahuje i pumpa krv, \u0161to rezultuje sr\u010danim zastojem. Asistolija se na EKG skeneru manifestuje kao potpuno ravna linija, i zahteva hitnu reanimaciju pacijenta. Smrtni ishod je izvesan ukoliko se za kratko vreme ne uspostavi elektri\u010dna aktivnost srca. Asistoliju mo\u017ee uzrokovati i davljenje, kao i intenzivno unutra\u0161nje krvarenje.<\/p>\n

Sr\u010dani zastoj se tako\u0111e mo\u017ee javiti i kao posledica sr\u010danog udara.<\/p>\n

Simptomi<\/strong><\/h2>\n

Simptomi sr\u010danog zastoja se skoro uvek javljaju iznenadno i ne mogu se predvideti. Mogu biti:<\/p>\n

Faktori rizika<\/strong><\/h2>\n

Faktori koji uti\u010du na pove\u0107anje rizika od sr\u010danoj zastoja skoro su isti kao kod koronarne arterijske bolesti. Ova boest je naj\u010de\u0161\u0107i i najdirektniji uzrok, i njeni faktori rizika su:<\/p>\n

<\/h2>\n

Komplikacije<\/strong><\/h2>\n

Sr\u010dani zastoj mo\u017ee izazvati trajno o\u0161te\u0107enje mozga ukoliko traje vi\u0161e od tri minuta. Stopa izle\u010denja je jako mala, a ukoliko sr\u010dani zastoj traje vi\u0161e od 10 minuta, ravna je nuli.<\/p>\n

 <\/p>\n

Prevencija<\/strong><\/h2>\n

Prevencija sr\u010danog zastoja svodi se na vo\u0111enje zdravog \u017eivota sa dosta fizi\u010dke aktivnosti. To zna\u010di regulisanje ishrane (smanjivanje unosa soli i masne hrane), kao i prestanak pu\u0161enja i konzumiranja alkohola. Pacijentima se tako\u0111e savetuje da izbegavaju stresne situacije.<\/p>\n

Pacijentima sa istorijom sr\u010danih bolesti u porodici preporu\u010duju se redovne lekarske kontrole kako bi se izbegle dodatne komplikacije. U slu\u010daju pove\u0107anog rizika od sr\u010danog zastoja, mo\u017ee se ugraditi potko\u017eni defibrilator, mali ure\u0111aj koji \u0107e reanimirati srce u slu\u010daju artimije ili nekog drugog zastoja.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-71530","disease","type-disease","status-publish","hentry"],"yoast_head":"\nSr\u010dani zastoj - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"sr_RS\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Sr\u010dani zastoj - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Sr\u010dani zastoj je nagli prestanak rada srca, koji se \u010desto naziva i klini\u010dka smrt.
