NCT ID NCT04680728

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

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 Results may not be published yet.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

Summary

This study examined 185 intensive care patients to understand how common venous congestion (a backup of blood in the veins) is and whether it contributes to organ problems like kidney or liver failure. Researchers used blood tests and ultrasound to check for signs of congestion. The goal is to better identify this condition in non-heart surgery ICU patients, which could lead to earlier treatment with diuretics.

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 this study confirms a link between venous congestion and organ failure in ICU patients, it could pave the way for targeted treatments like diuretics to improve outcomes.
What could go wrong
This is an observational study, not a treatment trial, so it cannot prove cause and effect. The findings may not apply to all ICU patients or lead directly to new therapies.
