Can a cooling blanket beat heat stroke faster?
NCT ID NCT05923931
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a cooling blanket helps people with heat stroke cool down faster than standard methods like ice packs and cool fluids. About 126 adults with heat stroke will be randomly assigned to receive either the cooling blanket or usual care. The goal is to see if the blanket speeds up temperature drop and reduces organ damage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cooling blanket
- What this could lead to
- If it works, this could provide a simple, effective way to cool heat stroke patients faster and reduce complications.
- What could go wrong
- This is a small, early-stage trial (126 participants) comparing two cooling methods, so results may not be definitive or widely applicable. The cooling blanket may not significantly improve outcomes over standard care.
