Overview
Brief Summary
By doing this study, the investigator hopes to learn how the levels of important proteins involved in inflammation change over time in patients with acute brain injury. The total amount of time participants will be asked to volunteer for this study is approximately two hours over a five day period.
Detailed Description
This pilot project is a prospective, observational study in 20 patients who are admitted to University of Kentucky (UK) Chandler Medical Center with a diagnosis of severe, non-penetrating traumatic brain injury (TBI) or aneurysmal subarachnoid hemorrhage (aSAH). All adult participants with a primary diagnosis of severe, non-penetrating TBI or aSAH who are admitted to the neuroscience or trauma intensive care units will be screened for potential inclusion into this study. Once a potential participant is identified, the legally-authorized representative will be approached for study consent and HIPAA authorization. If the participant regains consent capacity before the end of the cerebrospinal fluid (CSF) collection period, assent will be obtained from the research participant. In this research study, up to 5 small samples of CSF, will be carefully removed from the device, already in place, that drains excess CSF from the participant's head. The samples will be less than 1 teaspoon (\< 5 mL) each. These samples will be frozen and stored until samples from approximately 20 participants have been obtained. These samples will then be prepared and sent to a research laboratory to analyze the proteins in the samples collected from each research participant. Because the results of this study will not affect the treatment participants receive in or outside of the hospital, the investigator will not share the results of this study with the participant, their doctor or their family member(s).
