Melatonin or lidocaine to prevent confusion after hip replacement
Part of Brain & nervous system, Mental health clinical trials.
This trial tests if giving either oral melatonin or lidocaine during surgery can reduce the chance of confusion (delirium) in older adults after total hip replacement. It compares these two approaches to standard care.
Summary written for real people, not researchers, by Clin2.

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 trial tests if a long-acting numbing medicine (liposome bupivacaine) given before surgery can reduce pain and lower the risk of confusion (delirium) after hip fracture repair in older adults.
This trial tests if a non-invasive 40 Hz brain stimulation can prevent delirium (sudden confusion) in older adults after hip or knee replacement surgery. Delirium is common after surgery in elderly patients, and this treatment aims to lower that risk.
This study looks at whether older adults who get a hip replacement may experience confusion after surgery. It aims to find factors that might help prevent or reduce this confusion.
This study tests if two medicines, ketamine and dexmedetomidine, can help prevent confusion (delirium) after hip or knee replacement surgery. If you're having this surgery and are generally healthy, you may be able to join.
This trial tests if giving flumazenil after remimazolam sedation can help people think more clearly after hip replacement surgery. If you are having a planned hip replacement and are generally healthy, this study might be for you.
