Popis: | Cardiac arrest (CA), the sudden cessation of effective cardiac pumping function, is still a major clinical problem with a high rate of early and long‐term mortality. Post‐cardiac arrest syndrome (PCAS) may be related to an early systemic inflammatory response leading to exaggerated and sustained neuroinflammation. Therefore, early intervention with targeted drug delivery to attenuate neuroinflammation may greatly improve therapeutic outcomes. Using a clinically relevant asphyxia CA model, we demonstrate that a single (i.p.) dose of dendrimer‐N‐acetylcysteine conjugate (D‐NAC), can target “activated” microglial cells following CA, leading to an improvement in post‐CA survival rate compared to saline (86% vs. 45%). D‐NAC treatment also significantly improved gross neurological score within 4 h of treatment (p |
