Summary

This trial aims to see if using a type of ear stimulation called transcutaneous auricular neurostimulation (TAN) is safe and possible for patients in the ICU with traumatic brain injuries. They

Who is the study for?
This trial is for ICU patients with traumatic brain injury (TBI). It's aimed at those who can safely undergo neurostimulation therapy. Details on specific inclusion and exclusion criteria are not provided, but typically these would outline the severity of TBI, age range, and any other health conditions that might affect patient safety or the results of the study.
What is being tested?
The trial is testing a device called Sparrow Ascent which provides transcutaneous auricular neurostimulation (tAN) to see if it's safe for use in ICU patients with TBI and to observe its effects on inflammation markers, blood pressure, heart rate, intracranial pressure (ICP), and neurological function.
What are the potential side effects?
Specific side effects are not listed; however, since this is a feasibility and safety study of tAN in critically ill patients with TBI, potential side effects may include skin irritation at the stimulation site or changes in vital signs like blood pressure or heart rate.

Experimental Treatment
Group I: Determine the effect of tAN on serum concentrations of inflammatory mediators in TBI patientsExperimental Treatment1 Intervention
Subjects will receive treatment upon providing informed consent and will undergo transcutaneous auricular neurostimulation (tAN) once daily during their ICU stay, with the treatment duration not exceeding 10 days. Two blood samples will be collected daily: one before the tAN session and another two hours after the session. Participant data will be collected daily throughout the ICU stay. Additionally, surveys will be collected from registered nurses providing direct care to TBI patients enrolled in the tAN-TBI study to assess the compatibility of tAN with patient care processes in the ICU.
