Arm cuff treatment before surgery to prevent confusion
Part of Brain & nervous system clinical trials.
This study tests whether using a blood pressure cuff on the arm before surgery (called remote ischemic preconditioning) can help prevent confusion (delirium) after surgery. It is for older adults having planned non-cardiac surgery who are at risk for delirium.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 50 years or older.
- You are scheduled for a planned (non-emergency) surgery that is not on your heart, and you will receive general anesthesia.
- You have at least two of these risk factors for postoperative confusion: age 65 or older, higher anesthesia risk (ASA 3+), surgery lasting over 3 hours, taking more than 5 medications regularly, or symptoms of depression.
- You do NOT have significant arm problems like poor blood flow, swelling (lymphedema), recent arm surgery, injury, or skin sores.
- You have NOT had a heart attack, surgery, or brain surgery in the last month.
- You do NOT currently have confusion (delirium) or severe memory problems.

This trial tests whether a simple, non-invasive treatment called remote ischemic conditioning (briefly inflating and deflating a blood pressure cuff on your arm) can improve the safety and effectiveness of surgery for a chronically blocked carotid artery. It may help protect your brain during and after the procedure.
This study tests if a simple, non-invasive treatment (briefly inflating a blood pressure cuff on your arm) before surgery can reduce lung complications in older adults having non-heart, non-lung surgery. It may help protect your lungs during and after the operation.
This trial tests a simple, non-drug treatment called remote ischemic conditioning (repeatedly inflating and deflating a blood pressure cuff on an arm) to see if it can help people who have both a recent stroke and signs of heart injury. The goal is to help protect the heart and improve recovery after a stroke.
This study tests whether a simple arm-cuff procedure done before heart bypass surgery can help protect the heart in people with type 2 diabetes. The goal is to see if this technique reduces complications during and after the operation.
This trial tests whether a simple technique that briefly cuts off blood flow to the arm (like a blood pressure cuff) before heart surgery can protect the body from harmful inflammation and reduce organ damage. This might help patients recover better after surgery.
This study tests a treatment called remote ischemic conditioning (RIC) that uses brief periods of blood pressure cuff inflation on your arm to protect the brain after a bleed. The goal is to see if it is safe and helps improve recovery after a brain hemorrhage.
