How giving fluids changes tiny blood flow in critically ill patients with venous congestion.
Official title: Evaluation of the Microcirculatory Response to Fluids in Critically Ill Patients With Venous Congestion: A Prospective Observational Study
Run by Università Politecnica delle Marche · NCT07499401 · Data updated 2026-11-12
This project will see if giving a fluid bolus makes tiny blood flow worse in ICU patients who have venous congestion compared with similar patients without congestion.

Is this trial a fit for you?
✓Likely a good fit
Critically ill ICU patients with invasive or minimally invasive hemodynamic monitoring who are undergoing a clinician-ordered fluid challenge are the intended participants.
✕Probably not a fit
Patients who are pregnant, those who cannot have oral-cavity or bedside microcirculatory measurements (for example due to facial trauma), or those without appropriate hemodynamic monitoring are unlikely to be eligible or benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective observational study enrolling critically ill patients in the intensive care unit who have invasive or minimally invasive hemodynamic monitoring. Patients who receive a clinician-ordered fluid challenge will have microcirculatory measurements taken before and after the fluid is given. Investigators will compare microcirculatory changes between patients with clinical signs of venous congestion and those without. The aim is to determine whether fluid administration worsens microvascular perfusion in patients with venous congestion.
Why it matters
Potential benefit: If the study shows harm from fluids in congested patients, it could help clinicians avoid fluid strategies that worsen tissue perfusion.
How similar studies have gone: Previous work has looked at how fluids affect microcirculation in critically ill patients, but the specific effect in patients with venous congestion is less well characterized.
