Desflurane Potentially Induces Postoperative Cognitive Dysfunction in Elderly Patients Undergoing Perioperative Procedures by Modulating Cdc42 and Clock Proteins

Sponsor: Xiaguang Duan

Summary

This clinical trial investigates whether desflurane induces postoperative cognitive dysfunction (POCD) in elderly patients undergoing perioperative procedures by modulating Cdc42 and Clock proteins. 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. Study 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.
