Brain blood flow and confusion after surgery study
Part of Brain & nervous system, Mental health clinical trials.
This trial looks at how well the brain controls its own blood flow during non-cardiac surgeries. It aims to see if problems with this regulation are linked to confusion after surgery (delirium).
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 60 years or older.
- You are having a non-heart surgery, like vascular, liver, or spine surgery.
- You will need general anesthesia and a special blood pressure line (arterial line) for monitoring.
- You speak English.
- Your thinking and memory are generally okay (MoCA score of 10 or more).
- You do not have major vision problems.
- Your surgery is not an emergency.
- You have not had a stroke in the last 3 months.

This study tests a new way to predict delirium (sudden confusion) after heart surgery by using brain monitoring. It may help doctors detect early warning signs so they can act faster.
This study uses a special brain-wave monitor during your surgery to see if it can predict confusion or memory problems afterward. It may help you and your doctors better understand your recovery.
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
This trial measures brain signals to see if they can predict confusion (delirium) after surgery. It may help identify patients at higher risk so they can get extra care.
This study is looking at how well the brain regulates its blood flow during heart surgery and whether that affects the chance of becoming confused (delirium) after surgery. Researchers want to find ways to prevent delirium in older adults having heart surgery.
This study looks at interventions to help with “postoperative delirium,” a sudden confusion that can happen after surgery, and uses brain measures like EEG and optional MRI. It may help doctors identify who is at risk and learn what approaches are most helpful after surgery.
