Transauricular Vagal Nerve Stimulation Improves Postoperative Delirium in Elderly Patients

Not Applicable
Recruiting
Conditions
Vagus Nerve Stimulation
Interventions
Device: Transauricular Vagal Nerve Stimulation
Registration Number
NCT06421090
Lead Sponsor
Beijing Tiantan Hospital
Brief Summary

To investigate the efficacy and safety of perioperative Transauricular vagal nerve stimulation in improving Postoperative Delirium in elderly patients undergoing elective surgery Lay the groundwork for a Phase III study.

Detailed Description

This study aims to conduct a prospective, randomized controlled clinical trial on the preventive use of Transauricular vagal nerve stimulation(taVNS) to improve the incidence of Postoperative Delirium(POD) 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.

Incidence of POD at discharge or within 5 days postoperativelyAt discharge or within 5 days postoperatively

POD assessment was performed using the 3D-CAM scale estimate. Assessed 2 times daily until postoperative day 5 or hospital discharge.

All-cause mortalityon the 90 days
Postoperative pain1-5 days after surgery

VAS score

Incidence of cognitive declineDay 1 before surgery, day 5 after surgery, day 90 after surgery

The MMSE scale and MoCA scale was used for evaluation

Time of anesthesia recoveryWithin 2 hours after the end of the surgery
