Transcutaneous Auricular Neurostimulation for ICU Patients With Traumatic Brain Injury
(tAN-TBI)
What this study is about
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.
View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Post-resuscitation GCS score 12 or below and acute trauma-related intradural blood on head CT scan after TB
- Age 18 years or older (pediatric trauma patients are not routinely transported to Parkland)
- Consent from legally authorized representative
Exclusion criteria
- Hemodynamic instability
- Expected imminent mortality because of overwhelming neurological and/or systemic injury
- Unclear neurological status because of paralytic medications or intoxication with ethanol or other drugs
- Presence of other electrical stimulation devices (pacemaker, cochlear prosthesis, neurostimulator, etc.)
- Abnormal ear anatomy or ear infection
- Participant is pregnant or lactating
- Any other significant medical or psychosocial problems that, in the opinion of the investigator, would potentially cause harm to the participant, impact their ability to participate, or influence the results of the trial
Where

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
