Temperature management after ROSC includes a rewarming phase. What is the intended pace of rewarming?

• A. Spontaneous rewarming
• B. Controlled rewarming
• C. Rapid rewarming
• D. No rewarming

Answer: (B)

After ROSC, warming the patient should be done in a controlled, deliberate way. The intended pace is slow rewarming at about 0.25–0.5°C per hour. This gradual rise helps the body adjust to higher temperatures and reduces the risk of hemodynamic instability, electrolyte shifts (such as potassium, phosphate, and magnesium), and rebound fever or brain edema. By controlling the rate, clinicians can monitor and manage blood pressure, electrolyte levels, and temperature closely, improving stability as temperature normalizes. Spontaneous or rapid rewarming can lead to unpredictable changes and adverse effects, while not rewarming at all would undermine brain-protection goals.
