Arm Description
Infusion of 1L cold crystalloid solution (4°C) over 15 minutes
Passive external neck cooling with 1 EMCOOLS Brain.Pad (Emergency Medical Cooling Systems AG, Wien, Austria)
Outcomes
Primary Outcome Measures
Brain temperature
Primary endpoint: Change of brain temperature during one hour after start of cooling. Repeated measurement ANOVA for within subject contrasts (phase 1 (0 to 15min), 2 (15 to 30min), 3 (30 to 45min) and 4 (45 to 60min)) vs. baseline (-15 to 0min)
Secondary Outcome Measures
(Neuro-)vital parameters
Effects on (neuro-)vital parameters (e.g. HR, AP, ICP, CPP) are registered
Cerebral autoregulation
Cerebral auto-regulation parameters (e.g. PRx) are calculated on the basis of the (neuro-)vital parameters monitored.
Safety
Various safety parameters, such as bleeding complications, cardiac decompensation, or local skin irritations are assessed.

5. Study Description
Brief Summary
Mild hypothermia improves outcome in patients with global cerebral ischemia after cardiac arrest. Hypothermia seems promising also in other acute hypoxic-ischemic or in brain swelling associated cerebrovascular disease. The narrow-time-frame is a major issue ("time is brain"). To provide immediate cooling without delay, easy to use, mobile and effective methods are needed. Cold infusions (4 °C) are an accepted standard worldwide. EMCOOLS Brain.Pad (Emergency Medical Cooling Systems AG, Wien, Austria) is a new non-invasive surface cooling system. A comparison of these two induction methods has never been done before. Neither was the effect of the EMCOOLS Brain.Pad on brain-temperature measured. For the first time iCOOL 3 compares feasibility, safety and efficacy of the two methods.
