Cognitive Assessment And Post-Operative Complications After Surgery: Linking Anaesthesia And Risk
This study checks whether it is practical to give older adults memory tests and blood tests before and after major surgery. Researchers will compare the results with anaesthesia details, such as drugs used and brain-wave monitoring. It is a small feasibility study, meaning it tests the research methods, not a treatment. No phase was listed.
