The primary research questions are: (1) Does desflurane administration contribute to POCD in this patient population? and (2) Are alterations in Cdc42 and Clock protein levels associated with desflurane-induced POCD in elderly patients? To address these questions, elderly patients will be administered desflurane for anesthesia maintenance. Postoperative assessments will then compare blood levels of Cdc42 and Clock proteins, and examine related signaling pathways, between a control group and a POCD group.\n\nStudy participants will receive desflurane anesthesia maintained at a Bispectral Index (BIS) value of 40-60. Postoperative cognitive function will be assessed on the second day using the Montreal Cognitive Assessment (MoCA), and participants will be categorized into either a control group or a POCD group based on MoCA performance. Cognitive function and blood levels of Cdc42 and Clock proteins will be recorded. Furthermore, the study will also investigate associated signaling pathways.",[77,78,79,80,81],"Avascular Necrosis of the Femoral Head","Coronary Artery Disease (CAD)","Benign Prostatic Hyperplasia (BPH)","Cholecystitis","Knee Osteoarthritis","NOT_YET_RECRUITING","2025-01-12",{"date":85,"type":86},"2025-01-14","ACTUAL",{"date":88,"type":71},"2025-02-01",{"date":90,"type":71},"2025-05-10",{"name":58,"class":6},1]
