What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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

Summary

This study tests whether pressing on the abdomen with an ultrasound probe can temporarily stop blood flow in the main artery (aorta) in healthy adults aged 18-40. The goal is to see if this technique is effective and tolerable, potentially offering a more accurate way to control severe bleeding in emergencies. Participants will have their abdominal aorta compressed under ultrasound guidance for up to 30 seconds while blood flow is monitored.

What this could mean

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

Active substance
ultrasound-guided external abdominal aortic compression
What this could lead to
If successful, this technique could provide a more precise way to control severe bleeding in emergencies, potentially saving lives.
What could go wrong
This is a small feasibility study in healthy volunteers, so results may not translate to real trauma situations. The technique may be difficult to perform or cause discomfort.
