NCT ID NCT06504238

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study is testing several non-invasive methods—like pupil checks, EEG, and ultrasound—to see if they can detect life-threatening brain swelling earlier than current methods. Researchers will monitor 720 patients with acute brain injuries in the ICU. The goal is to find reliable, easy-to-use tools that could speed up treatment and improve outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to better, faster detection of dangerous brain swelling without invasive procedures, potentially saving lives and reducing disability.
What could go wrong
This is an observational study, not a treatment trial. The methods are still being tested for accuracy, and results may not change current care immediately.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Admitted under Neuro intensivist primary or consultative care. * At least one head computed tomography (CT) scan demonstrating intracranial pathology that may lead to life-threatening mass effect (i.e. traumatic brain injury, ischemic or hemorrhagic stroke, epidural or subdural hematoma, subarachnoid hemorrhage, diffuse hypoxic injury, metabolic cerebral edema, tumor) * Concern for Life Threatening Mass Effect * Glasgow Coma Score (GCS) \<9 * Anticipated stay \>24 hours Exclusion Criteria: * Comfort measure only * Any other criteria that the PI deems that makes the patient inadequate for the study * Sub-exclusion criteria for specific non-invasive measurements include: * Orbital injury (pupillometry, ONSD) * Traumatic injury or surgery that precludes use of B4C device * Presence of supratentorial craniectomy or craniotomy that has not healed and is mobile/bone defects/scalp injury \[EEGelectroencephalogram (EEG), Brain4Care\] * Presence of extensive scalp injury
