Using non-invasive tools to monitor brain health after surgery

Transcranial Doppler, Optic Nerve Envelope Diameter and Quantitative Pupillometry Measurements in Postoperative Resuscitation Neurosurgery

Observational Centre Hospitalier Universitaire de la Réunion · NCT05843214

This study is testing non-invasive tools to see if they can help monitor brain health and catch any early problems in French-speaking patients after they have surgery on their brain.

What this trial studies

This observational study evaluates the effectiveness of non-invasive neuromonitoring tools, including transcranial Doppler, optic nerve envelope diameter measurement, and quantitative pupillometry, in patients undergoing controlled intracranial surgery. The aim is to detect early signs of postoperative neurological deterioration by monitoring various physiological parameters. The study focuses on French-speaking patients scheduled for surgery more than 48 hours in advance, ensuring a comprehensive assessment of their neurological status during recovery.

Who should consider this trial

Good fit: Ideal candidates are French-speaking patients scheduled for regulated intracranial surgery more than 48 hours in advance.

Not a fit: Patients with chronic subdural hematoma, isolated cerebral endovascular procedures, or specific ocular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the early detection of neurological complications in patients after brain surgery, potentially improving patient outcomes.

How similar studies have performed: While the use of these non-invasive monitoring tools is common in acute brain injury management, this specific application in controlled intracranial surgery is novel and has not been extensively tested.
