Automated Robotic TCD in Traumatic Brain Injury (ART-TBI)
Virginia Commonwealth University
Summary
This study's objective is to determine the safety, feasibility and efficacy of prolonged automated robotic TCD monitoring in critically ill patients with severe TBI across multiple clinical sites with varying levels of TCD availability and experience
Description
Upon informed consent, patients will undergo daily automated robotic TCD monitoring sessions for up to 4 hours a day for a total duration of at least 3 days and up to 5 days whenever clinically feasible. TCD monitoring of bilateral middle cerebral artery cerebral blood flow velocity (MCA CBFV) will be performed using a robotic TCD system equipped with bilateral 2-MHz Doppler probes. This system allows for continuous bilateral extended duration recording of MCA CBFV, using robotically controlled TCD probes that allow automated angle correction to maintain optimal MCA insonation.
