The design of the PRINCESS 2 trial: A randomized trial to study the impact of ultrafast hypothermia on complete neurologic recovery after out-of-hospital cardiac arrest with initial shockable rhythm
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) patients with initial shockable rhythmplanned sample size
- Participants
- 1,022 patients
- Planned comparison

- Primary endpoint
- Survival with complete neurologic recovery (modified Rankin scale (mRS) 0-1)
- Follow-up
- 90 days
