NCT ID NCT07465419
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether inserting a central line into the neck vein affects brain pressure in 50 ICU patients on breathing machines. Doctors used ultrasound to measure the nerve sheath at the back of the eye before and after the procedure. The goal was to see if this simple method could detect any pressure changes.
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 help doctors understand whether placing a central line in the neck safely affects brain pressure in ICU patients.
What could go wrong
This is a small, completed observational study with only 50 participants. It does not test a treatment, so it cannot directly lead to new therapies.
