Summary

After heart surgery, up to half of patients may experience a sudden state of confusion called delirium, which can slow recovery. This study aims to build a computer-based early warning system that combines real-time brain wave (EEG), brain oxygen, and heart function measurements to predict delirium 1 to 6 hours before it starts. Researchers will enroll 200 adults aged 18 to 80 in the ICU after heart surgery, continuously recording their vital signals and regularly checking their mental state. The goal is to give doctors a window to intervene early, potentially improving recovery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this early warning system could help doctors prevent delirium after heart surgery, leading to faster recovery and shorter ICU stays.
What could go wrong
This is an observational study to develop a prediction tool, not a treatment test. The system may not prove accurate enough for real-world use, and it does not test any intervention to prevent delirium.
