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
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 This study
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are observing adults who need a radial artery catheter for elective heart surgery to see whether the procedure changes the artery's size, blood flow, or fine motor skills over three months. The study uses ultrasound to measure the radial and ulnar arteries and the Purdue Pegboard test to check hand performance. Participants are compared to themselves over time, and the cannulated arm is compared with the other arm. The goal is to understand any lasting effects of this common monitoring technique.

What this could mean

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

Active substance
radial artery catheterization
What this could lead to
If the study finds lasting changes in the artery or hand function, it could inform how doctors choose and monitor arterial lines for heart surgery. It may also guide future research into safer cannulation techniques.
What could go wrong
This is a small observational study of 103 people having heart surgery, so it cannot prove cause and effect. Any changes seen might be temporary, related to the surgery itself, or not apply to other patients or settings.
