Nerve block before limb procedure to prevent confusion in older adults
Treatments studied
Part of Brain & nervous system, Heart & circulation, Mental health clinical trials.
This study tests whether a numbing injection near the neck (a 'stellate ganglion block') given before a planned leg or arm blood-flow procedure can help prevent confusion or disorientation (delirium) after surgery in older adults. If you are 65 or older and having a planned vascular procedure, this simple injection might reduce your risk of post-surgery confusion.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 65 years old or older.
- You must be having a planned (non-emergency) procedure to restore blood flow in your limbs.
- You must be in generally stable health (classified as ASA I-III, meaning mild to moderate health issues).
- You (or your legal guardian) must be able to understand and sign a consent form.
- You cannot have significant memory loss or dementia, severe hearing/vision loss, or major psychiatric conditions like schizophrenia.
- You cannot have severe heart, liver, or kidney disease (e.g., dialysis), or be allergic to numbing medications.
