What is a central component of post-arrest management to minimize brain injury?

• A. Maintaining adequate perfusion and perfusion pressure
• B. Early ambulation
• C. Reducing sedation aggressively
• D. Immediate discharge

Answer: (A)

Maintaining adequate perfusion and perfusion pressure to support cerebral blood flow is essential after cardiac arrest to minimize brain injury. The brain remains vulnerable even after circulation is restored because injury accrues from the initial ischemia and from reperfusion injury; keeping blood flow adequate helps deliver oxygen, clear metabolic byproducts, and preserve neuronal function. Cerebral perfusion pressure, roughly linked to mean arterial pressure minus intracranial pressure, guides how well the brain is perfused. In practice, aiming to keep MAP around 65 mmHg or higher supports cerebral perfusion and reduces secondary brain injury. Other options don’t address this critical need for brain protection after arrest—ambulation provides no immediate brain protection, aggressive sedation lacks context and can compromise stability, and discharge ignores ongoing risk.
