Transcutaneous Auricular Neurostimulation for ICU Patients With Traumatic Brain Injury

NCT06467708 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 42

No results posted yet for this study

Summary

The overarching goal of this pilot study is to assess the feasibility and safety of transcutaneous auricular neurostimulation (tan) in ICU patients with TBi and to determine the effect of tan on serum markers of inflammation. exploratory analyses will examine effects on such physiological parameters as blood pressure, heart rate, and intracranial pressure (iCP), as well as measures of neurological function.

Conditions

  • TBI (Traumatic Brain Injury)

Interventions

DEVICE

Sparrow Ascent Transcutaneous Auricular Neurostimulation (tAN)

This method of simultaneous vagal and trigeminal stimulation via the external ear is known as transcutaneous auricular neurostimulation (tAN), as the targets of electrical stimulation include the auricular branch of the vagus nerve (ABVN) and auriculotemporal nerve (ATN), which is a branch of the mandibular division of the trigeminal nerve. Electrodes applied to select dermatome regions can target ear neural structures and deliver non-invasive vagus nerve stimulation (VNS) and trigeminal nerve stimulation (TNS).
