Targeted Temperature Management (TTM) is considered primarily for which purpose in post-cardiac arrest care?

• A. It Is a Routine Measure for All Patients
• B. It Is a Neuroprotective Strategy Considered for Eligible Patients
• C. It Is Contraindicated in All Post-Arrest Patients
• D. It Is Used Only in Pediatric Patients

Answer: (B)

Targeted Temperature Management is used to protect the brain after cardiac arrest. By cooling the body to a mild hypothermic range, the brain's metabolic rate drops and the cascade of injury that can follow reperfusion is attenuated. This neuroprotective effect is the reason it’s considered for patients who remain comatose or have an unreliable neurologic exam after return of spontaneous circulation. It isn’t applied to every post-arrest patient; eligibility depends on clinical status and absence of contraindications. It’s not limited to pediatric patients and is used in adults when appropriate. In practice, clinicians typically aim for a target temperature in the 32–36°C range for a defined period and then rewarm gradually to minimize physiological stress.
