简要总结
The aim of this clinical trial is to study the impact of ultra-early transnasal evaporative cooling after cardiac arrest and subsequent hypothermia at hospital, on survival with complete neurologic recovery, compared to currently recommended normothermia. The study population will consist of patients 18-79 years old, with out-of-hospital cardiac arrest with initial shockable rhythm.
The main research question it aims to answer is whether there is a difference in survival with complete neurologic recovery at 90 days after cardiac arrest between the group of patients that received ultra-early cooling, compared to the group that was treated with normothermia.
Participants will be randomized to two groups. One group (the intervention group) will receive ultra-early trans-nasal evaporative cooling initiated by EMS personnel at the scene of the cardiac arrest, and subsequent systemic hypothermia for 24 hours at hospital arrival. The other group (the control group), will receive standard of care (advanced cardiac life support and normal body temperature (normothermia)).

盲法说明
Patients in the intervention group will be treated with hypothermia, which makes blinding for care provider and next of kin difficult in the intervention phase (first 36 h). Participants will be informed of which group the were assigned to if they regained consciousness. The study personnel assessing neurologic outcome at discharge and at 90 days will be blinded for which study group the participant belongs to. In addition, the physician performing the prognostication at 72 hours from cardiac arrest will be a neurologist, intensivist or other specialist experienced and will be blinded for group allocation, but not for relevant clinical data.

结局指标
主要结局
Proportion of patients surviving with complete neurologic recovery at 90 days defined as modified Rankin scale (mRs) of 0-1.
时间窗: Day 90
The modified Rankin Scale is a scoring system on neurologic function ranging from 0-6, where 0 means no symtoms at all, higher numbers indicating increasing neurologic disabilities and 6 equals death.
次要结局
- Proportion of patients alive at hospital discharge(Day 1-90)
- Proportion of patients with sustained ROSC (return of spontaneous circulation) and admitted alive to hospital(Day 1)
- Proportion of patients alive at 90 days(Day 90)
- Proportion of patients with Modified Rankin scale 0-3 at hospital discharge(Day 1-90)
- Proportion of patients with Modified Rankin scale 0-3 at 90 days(Day 90)
- Device related adverse event rate within the first 24 hours(Day 1)
- Proportion of patients with new cardiac arrest prior to hospital admission(Day 1)
- Composite serious adverse event rate within the first 7 days(Day 1-7)
