Orexin and confusion after surgery in older adults
Part of Brain & nervous system, Mental health clinical trials.
This study looks at a brain chemical called orexin (which helps control wakefulness) in older adults after surgery. The goal is to see if orexin levels are linked to confusion or agitation that can happen when waking up from anesthesia. If you take part, your blood will be tested before and after surgery.

This study looks at how brain “metabolomics” (small chemical signals in the brain/body) relate to thinking or mood problems that can happen after surgery in people age 65 and older. It may help doctors understand who is more likely to have these side effects after an operation.
This study tests whether avoiding opioid painkillers during anaesthesia can reduce confusion after surgery in older adults. It is specifically for people 65 and older having stomach or intestine surgery.
This study looks at older patients (65 and older) who have had surgery and anesthesia. It aims to find who is at risk for confusion (delirium) and memory problems afterward. The goal is to help doctors prevent these issues.
This study tests whether a sleep medication called lemborexant can help older adults recover their thinking and memory more quickly after surgery. It may reduce confusion or delirium that sometimes happens after an operation.
This trial tests giving either lidocaine or dexmedetomidine during abdominal surgery to see if it helps keep the brain healthy and lowers the chance of waking up confused or agitated. It is for older adults having planned abdominal surgery who are otherwise in fairly good health.
This study looks at how giving extra oxygen during surgery affects brain function and confusion (delirium) in older adults. It involves placing a small sensor on your forehead to measure brain oxygen levels.
