Cooling time trial for kids after heart stopping: could longer be better?
NCT ID NCT05376267
First seen Jun 27, 2026 · Last updated Jul 14, 2026 · Updated 2 times
Summary
This study tests different lengths of body cooling in children who remain unconscious after a cardiac arrest outside the hospital. The goal is to see if longer cooling helps protect the brain and improve recovery. The trial will enroll 900 children and follow them for one year.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Therapeutic hypothermia (controlled body cooling)
- What this could lead to
- If it works, this could identify the optimal cooling duration to improve brain function and survival in children after cardiac arrest.
- What could go wrong
- This is an early-phase trial with no definitive results yet. The optimal duration may not improve outcomes, and longer cooling could carry risks like infection or bleeding.
