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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 how pressure inside the abdomen changes in critically ill adults who receive continuous renal replacement therapy, a form of kidney dialysis used in intensive care. They measure the pressure through the patient's existing urinary catheter at set times over 72 hours. The study also tracks fluid balance, blood pressure, urine output, illness severity, length of stay, and 30-day survival to see how these relate to pressure changes. No extra treatments are given for the study.

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 researchers learn how abdominal pressure shifts during continuous kidney dialysis, doctors may one day adjust fluid removal or timing to avoid dangerous pressure buildup in critically ill patients.
What could go wrong
This is a small observational study in one hospital's ICU, so its patterns may not apply to other patients or settings. Measuring pressure through a bladder catheter can be unreliable if the catheter is blocked or the patient has certain pelvic conditions.
