Can a Triple-Dose of ICU tweaks save more brains after cardiac arrest?
NCT ID NCT05564754
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at 3,500 unconscious patients who survived a cardiac arrest to find the best combination of sedation, fever control, and blood pressure management in the ICU. Each patient gets one of two levels for each factor (e.g., deep vs. light sedation, tight vs. loose fever control, high vs. standard blood pressure target). The goal is to see which approach leads to more people alive and with good brain function at 6 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Feedback-controlled temperature device; vasopressors; sedation drugs
- What this could lead to
- If it works, this could establish a standard ICU protocol to improve survival and brain function after cardiac arrest.
- What could go wrong
- This is a large trial but still testing combinations of existing treatments; results may not show a clear winner or may not apply to all patients.
