Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are elderly patients aged 65 and older who are scheduled for surgeries lasting at least two hours and will have a postoperative hospital stay of four days or more.
✕Probably not a fit
Patients undergoing neurosurgery or cardiac surgery, emergency surgeries, or those with severe cognitive dysfunction may not benefit from this study.

What this trial studies
This clinical trial investigates the effectiveness of transcutaneous auricular vagus nerve stimulation (taVNS) in preventing postoperative delirium (POD) in elderly patients undergoing anesthesia for surgery. Participants will be randomly assigned to receive either standard or low stimulation parameters of taVNS, and the incidence of POD will be evaluated within five days post-surgery. Secondary outcomes will assess cognitive impairment, mortality rates, adverse events, and length of hospital stay. The study aims to provide evidence for the safety and efficacy of taVNS in improving postoperative brain health.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the incidence of postoperative delirium in elderly patients, improving their recovery and overall health outcomes.
How similar studies have gone: While the use of vagus nerve stimulation is a novel approach in this context, similar studies have shown promising results in related areas of postoperative care.
