Study of Automated Robotic Transcranial Doppler Monitoring in Adults with Severe Traumatic Brain Injury

What this Trial Is About

Researchers are evaluating the safety, feasibility, and effectiveness of prolonged automated robotic transcranial Doppler TCD monitoring in critically ill patients with severe traumatic brain injury TBI. The study aims to assess this technology across multiple clinical sites with varying levels of TCD availability and experience to better understand its clinical utility. Participants will undergo daily sessions of automated robotic TCD monitoring for up to 4 hours each day, for a minimum of 3 days and up to 5 days when possible. The monitoring uses a robotic system with bilateral 2-MHz Doppler probes to continuously record cerebral blood flow velocity in both middle cerebral arteries. This system includes automated angle correction to maintain optimal measurement quality. During the study, participants will be monitored for safety concerns such as discomfort, device dislodgement, and skin changes at the probe site. Feedback will be collected from nurses and clinicians to evaluate safety and feasibility. Researchers will also assess the adequacy of temporal windows and insonation quality of the arteries. The total study duration includes up to 5 days of monitoring with ongoing safety and usability assessments.
