Crainio non-invasive intracranial pressure monitor for traumatic brain injury

Crainio Non-invasive Intracranial Pressure Monitor for Traumatic Brain Injury: Product Development

Not applicable Interventional Crainio Ltda · NCT06453733

This project will test whether the Crainio device can non‑invasively detect raised intracranial pressure in adults with traumatic brain injury by comparing its readings to standard invasive monitors.

What this trial studies

This feasibility study will enroll 54 adults with traumatic brain injury who already have invasive ICP monitoring, collecting cerebral photoplethysmogram signals concurrently with invasive ICP measurements over a 12‑month period. The collected data will be used to train and validate Crainio machine learning algorithms to detect raised ICP (>20 mmHg) with a target of at least 90% sensitivity and specificity. Secondary analyses will examine how factors like skin tone, skull thickness and density affect signal quality, and will record device tolerability and staff acceptance. The work is conducted at the Royal London Hospital in collaboration with academic and funding partners and focuses on developing a continuous external nICP monitoring approach.

Who should consider this trial

Good fit: Adults aged 16–99 with traumatic brain injury admitted to the Royal London Hospital who are receiving invasive ICP monitoring and have intact forehead skin are eligible.

Not a fit: Patients with decompressive craniectomy, open external ventricular drains, non‑intact forehead skin, or who are not expected to survive the next 12 hours are excluded and unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the device could provide continuous non‑invasive ICP monitoring that reduces the need for invasive bolts or ventricular catheters and their associated risks.

How similar studies have performed: Prior non‑invasive ICP approaches (e.g., transcranial Doppler, retinal vein measures) have produced mixed, largely non‑continuous results, and continuous PPG‑based machine‑learning methods like Crainio remain relatively novel and unproven clinically.
