Prehospital cooling with hypothermia caps (PreCoCa): a feasibility study

Area of Science:

• Emergency Medicine
• Cardiology
• Neuroscience

Background:

• Animal studies indicate early therapeutic hypothermia post-cardiac arrest improves neuroprotection.
• Optimal methods for rapid, safe hypothermia induction are not yet established.
• Prehospital cooling is crucial for timely intervention.

Purpose of the Study:

• To evaluate the feasibility of using hypothermia caps in the prehospital setting.
• To assess the safety and effectiveness of prehospital hypothermia cap application.
• To determine the impact on patient temperature upon hospital admission.

Main Methods:

• A study was conducted using hypothermia caps on patients post-out-of-hospital cardiac arrest.
• Cooling initiation and temperature monitoring were performed prehospital.
• A control group without prehospital cooling was used for comparison.

Main Results:

• Hypothermia caps were applied within a median of 10 minutes after return of spontaneous circulation (ROSC).
• A statistically significant drop in tympanic temperature was observed before hospital admission (P < 0.001).
• Patients receiving prehospital cooling had significantly lower temperatures on admission compared to the control group (P < 0.001).

Conclusions:

• Prehospital hypothermia caps are a safe and effective method to initiate therapeutic hypothermia.
• This approach is rapidly available, inexpensive, non-invasive, and easy to implement.
• Early initiation of cooling via hypothermia caps can enhance neuroprotective benefits after cardiac arrest.
