Ear (auricular) vagus nerve stimulation to speed recovery after acute neurocritical illness
Official title: The TAVERN Trial: Transcutaneous Auricular Vagus Enhanced Recovery in the NeuroICU - A Study of Clinical Outcomes and Cost Reduction
Run by Washington University School of Medicine · NCT07219108 · Data updated 2026-11-12
This trial will test whether noninvasive ear (auricular) vagus nerve stimulation helps adults admitted to the NeuroICU have fewer infections, need fewer tracheostomies, and leave the hospital sooner.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) admitted to the NeuroICU within 36 hours of an acute medical or neurological event who meet at least one critical-illness predictor (GCS 4–12, NIH Stroke Scale ≥6, ongoing mechanical ventilation, vasopressor support, subarachnoid hemorrhage, intracerebral hemorrhage with >5 mL hematoma, moderate–severe TBI, or refractory status epilepticus) are ideal candidates.
✕Probably not a fit
Patients with systemic immunosuppression, active cancer therapy, implanted electrical devices (e.g., pacemaker), or sustained bradycardia on admission are excluded and are unlikely to receive benefit from this intervention.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults admitted to the NeuroICU within 36 hours of an acute neurological or medical event are randomized to transcutaneous auricular vagus nerve stimulation (taVNS) or sham stimulation. Blood samples for inflammatory markers are collected on admission and serially during the hospital stay while clinicians track infections, need for tracheostomy, vital signs, blood glucose, peri-hematomal edema, and related interventions. Outcomes include rates of hospital-acquired infection, tracheostomy, ICU and hospital length of stay, physiologic measures, inflammatory marker trends, discharge destination, functional scores up to one year, and a health economic cost analysis. No additional clinic visits are required specifically for the research protocol.
Why it matters
Potential benefit: If successful, taVNS could reduce infection rates and prolonged intubation, shorten ICU and hospital stays, and lower overall care costs for neurocritical patients.
How similar studies have gone: Animal studies and some human work with implantable VNS show anti-inflammatory effects, but transcutaneous auricular VNS in acute neurocritical care is relatively novel with limited clinical data to date.
