What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at whether an ultrasound scan of veins in the belly and leg can predict a dangerous drop in blood pressure after spinal anesthesia. Researchers will measure these veins in 110 men scheduled for prostate surgery, then track their blood pressure after anesthesia. The goal is to find a simple, non-invasive way to identify patients at risk and prevent complications.

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 give doctors a simple, non-invasive way to predict and prevent dangerous drops in blood pressure during spinal anesthesia.
What could go wrong
This is a small, early observational study, not a treatment trial. The ultrasound method may not prove reliable enough for routine use.
