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 Results may not be published yet.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.

Summary

This study looked at 40 children with congenital heart disease who had heart surgery. During surgery, doctors used a special filtering technique called SBUF-SMUF to remove inflammatory substances from the blood. The goal was to see how this affected inflammation and recovery. The study was observational, meaning it only described what happened without comparing to another group.

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 refine ultrafiltration methods to reduce inflammation and improve recovery after pediatric heart surgery.
What could go wrong
This is a small, observational study with no control group, so results may not prove cause and effect or apply to other hospitals.

This is an AI summary of the original study and may miss details. Read our disclaimer.
