Sous vide device tested for thawing frostbite
NCT ID NCT05280301
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a sous vide device, normally used for cooking, can keep a warm water bath at a steady temperature to rewarm frostbitten hands and feet. Seven people with acute frostbite took part. Researchers measured how long it took for the frozen areas to become warm and soft again, and asked providers how easy the device was to use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sous vide device (SVD) used to heat and maintain a warm water bath for rewarming frostbitten extremities
- What this could lead to
- If it works, this could offer a simple, controlled way to rewarm frostbitten hands and feet in emergency settings.
- What could go wrong
- This is a very small, early study (only 7 participants) that only tested the device's ability to heat water and rewarm tissue. It does not prove the device improves long-term outcomes or prevents tissue damage.
