Targeted temperature management after cardiac arrest should be maintained for how long?

• A. 12 hours
• B. 48 hours
• C. 72 hours
• D. 24 hours

Answer: (D)

Targeted temperature management after cardiac arrest aims to protect the brain during the vulnerable early period after the event. Maintaining the chosen temperature for about one day (roughly 24 hours) provides this neuroprotection during the critical reperfusion window without adding unnecessary risks. Why 24 hours is best: Evidence shows that keeping the patient at the target temperature for around 24 hours offers neurologic benefit and has not been shown to improve outcomes with longer durations. Extending cooling beyond 24 hours can raise the chance of complications such as infections, electrolyte disturbances, and cardiovascular instability, without clear extra protection to the brain. After 24 hours, rewarming should occur gradually to avoid hemodynamic or cerebral instability.
