Targeted Temperature Management at 33°C Versus Controlled Normothermia for In-hospital Cardiac Arrest

"Cooling and maintenance phase :~The aim is to achieve the target temperature of 33±0.5°C within 60 minutes after randomization. The target temperature of 33±0.5°C and device setting of 33°C will be maintained until 28 hours after randomization.~\- Rewarming: Normothermia will be restored by gradual rewarming at a rate of 0.2°C/h.~\- After rewarming: After 40 hours, in those participants who are still comatose or sedated, normothermia (36.5-37.7°C) will be maintained until 72 hours after randomization, and active warming will be avoided."

"Participants whose initial temperature is below 33°C may be actively rewarmed to 36.5°-37.7°C, at which point active rewarming will be stopped and passive rewarming performed according to the latest guidelines. Participants whose initial temperature is above 33°C will not be actively rewarmed to normothermia. The goal will be to maintain temperature no higher than 37.8°C.~After 40 hours, in those participants who are still comatose or sedated, normothermia (36.5-37.7°C) will be maintained until 72 hours after randomization, and active warming will be avoided."
