Conditions

TBI (Traumatic Brain Injury)

Brief summary

Preliminary evaluation of depth electrode recording and novel algorithms to determine Cortical Spreading Depolarization's (CSD) following traumatic brain injury (TBI) requiring neurosurgical intervention.

Detailed description

During the standard of care External Ventricular Drain (EVD) placement, a depth electrode with minimal modification to the standard surgical procedure will be placed. This will allow electrocorticogram (ECoG) recordings. An ECoG will be reviewed by a study Neurosurgeon to understand the association between cortical spreading depression and pathological findings on imaging. The recordings help create a novel algorithm in order to detect CSD's. This may ultimately provide significant benefit to society through the diagnosis and treatment of secondary injury associated with traumatic brain injury.

Interventions

DEVICEdepth electrodes

The study will be conducted at a single center, in TBI patients requiring neurosurgical intervention in the form of EVD placement. During neurosurgical intervention at the bedside in the Intensive Care Unit (ICU), a single depth electrode will be placed in the brain adjacent to the EVD catheter in the same burr hole. After EVD and depth electrode placement, continuous recording of ECoG activity as well as relevant physiological parameters will be performed for the duration of clinically indicated invasive neuromonitoring in accordance with the standard of care for TBI patients. A single recording station is currently available for data collection, therefore, with an anticipated average recording period of 14 days, the study will take greater than 210 days to complete for a total of 15 patients.

Detecting CSDs in TBI patients2 yearsThe primary endpoint is to determine the feasibility of using depth electrodes in conjunction with novel analytical algorithms to detect CSDs in TBI patients. A single depth electrode will be placed at the same time the EVD is performed. ECoG recordings from each patient will be recorded.
