Smart hydration during surgery may shield Seniors' brains

This study looked at 180 older adults (65+) having major abdominal cancer surgery to see if giving fluids based on real-time body signals (goal-directed fluid therapy) helps prevent short-term memory and thinking problems after surgery. Patients received either this personalized approach or standard care. The main goal was to compare changes in thinking test scores from before surgery to one and seven days after. The study aims to find better ways to support brain health during surgery in elderly patients.
