Neck vein catheter and brain pressure during surgery
Part of Brain & nervous system clinical trials.
This study checks whether placing a small tube in a neck vein changes pressure inside the skull or blood flow in the brain. It uses a simple eye ultrasound to measure these changes during surgery, which could help doctors watch for brain pressure issues safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years old or older.
- You will be having surgery with general anesthesia (fully asleep).
- You will need a special IV line placed in a large neck vein as part of your care.
- You must be able to have an ultrasound of your eye to measure the nerve behind it.
- You cannot have any known brain condition that affects pressure inside the skull.
- You cannot have certain eye problems like recent injury, surgery, or infection that would make the eye ultrasound hard to do.

This study tests a new way to estimate pressure inside the skull without extra needles or surgery. It uses a soft mask and ultrasound to measure pressure at a vein near the eye, aiming to find a safer alternative for people who already have a standard brain-pressure monitor in place.
This study is testing a new way to measure pressure inside the skull without needing a separate procedure. It may be an option for people having brain surgery, getting spinal taps, or needing their VP shunt adjusted.
This study looks at how a certain way of delivering blood to the brain during surgery on the upper aorta affects eye pressure, which may indicate brain swelling. It may help doctors improve safety during these surgeries.
This study uses ultrasound pictures of a large neck vein to help doctors place a central line and estimate the pressure inside the vein. It may improve the safety and accuracy of placing the line and reduce the need for more invasive pressure measurements.
This study uses ultrasound to look at a vein in your neck before and after major abdominal surgery to understand how surgery affects your kidneys. Researchers hope this simple imaging technique might help predict and prevent kidney problems after surgery.
This study tests whether a quick ultrasound of a neck vein can help predict if your blood pressure will drop when anesthesia starts. This might help doctors manage blood pressure more safely during gallbladder surgery.
