What is a primary post-arrest objective regarding temperature?

• A. Maintain fever above 38°C for 24 hours
• B. Maintain normothermia without active cooling
• C. Maintain targeted temperature management in the 32-36°C range for 24 hours with careful rewarming
• D. Do not alter body temperature

Answer: (C)

After resuscitation, the brain is highly vulnerable to further injury from reperfusion and inflammation. The main goal is to protect neural tissue by actively controlling temperature rather than letting it drift toward fever or remain untreated. Maintaining targeted temperature management in the 32-36°C range for about 24 hours provides a neuroprotective effect: it lowers cerebral metabolic demand, stabilizes cellular processes, and dampens inflammatory injury, all of which can improve neurological outcome. Rewarming must be gradual to avoid destabilizing hemodynamics and electrolyte shifts. Fever worsens brain injury, so avoiding fever is also a key part of this approach. Simply keeping the patient normothermic without cooling doesn’t guarantee against fever or the benefits of controlled temperature management, whereas the described plan offers a structured, evidence-supported protection window.
