Clinical Trial Summary

According to the 3D-CAM scale, evaluate the incidence of Postoperative Delirium within 5 days after surgery in elderly patients receiving Transauricular vagal nerve stimulation.The results are expected to provide evidence of the safety and efficacy of perioperative prophylactic use of taVNS in the clinical application of improving postoperative brain health in elderly patients, as well as theoretical and practical basis for subsequent studies or clinical applications.

Description:

This study aims to conduct a prospective, randomized controlled clinical trial on the preventive use of Transauricular vagal nerve stimulation to improve the incidence of Postoperative Delirium in elderly patients undergoing anesthesia surgery. The intervention group will receive taVNS, while the control group will only wear a taVNS stimulator without current stimulation. The main outcome measure of the study was the incidence of POD within 5 days after surgery. Secondary outcome measures include incidence of new mild and severe postoperative neurocognitive impairment during hospitalization and 90 days, all-cause mortality rate at 90 days, incidence of related adverse events, and length of stay.
