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

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 Results may not be published yet.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

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 how giving fluids affects the smallest blood vessels in critically ill patients with venous congestion. Researchers will give a small amount of fluid and check blood flow in the mouth before, right after, and 30 minutes later. The goal is to see if fluids help or hurt these patients, which could guide better treatment in the ICU.

What this could mean

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

Active substance
fluid challenge (intravenous fluids)
What this could lead to
If successful, this could help doctors decide when to give fluids to ICU patients with venous congestion, potentially avoiding harm.
What could go wrong
This is a small, early observational study with only 30 participants, so results may not apply broadly. It does not test a new treatment.

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