Brief Summary

Fluid responsiveness is a critical determinant guiding fluid therapy in critically ill patients. However, excessive fluid administration can result in fluid overload, leading to venous congestion and worse clinical outcomes. Venous congestion, a marker of impaired fluid clearance, is increasingly recognized as a significant contributor to poor prognosis. Previous studies have demonstrated the coexistence of fluid responsiveness and venous congestion in critically ill patients. Notably, these studies were limited by the absence of fluid challenge-the gold standard for assessing fluid responsiveness-leaving the dynamic relationship between fluid responsiveness and venous congestion incompletely understood. This study aims to investigate the interplay and temporal evolution of fluid responsiveness and venous congestion following a standardized fluid challenge in critically ill patients.

Outcome Measures

Primary Outcomes (1)

  • The difference in venous congestion (VExUS) changes between fluid responders and non-responders following a fluid challenge.

    before and after 15-minute fluid challenge.

Secondary Outcomes (1)

  • The differential evolution of venous congestion (VExUS) changes between fluid responders and non-responders 1 hour after a fluid challenge.

    1 hour after fluid challenge

Study Arms (2)

Fluid Responder

Patients with an aumentation of cardiac index\>= 15% after a fluid challenge

Fluid Non-responder

Patients without an aumentation of cardiac index\>= 15% after a fluid challenge

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Critically ill patients with evidence of inadequate tissue perfusion, who are already monitored using a pulse wave contour analysis-derived estimation of cardiac output (either calibrated or uncalibrated),and for whom clinicians have decided to administer volume expansion through intravenous crystalloid infusion.

You may qualify if:

  • Age ≥ 18 years
  • Hospitalized in the intensive care unit (ICU)
  • Hemodynamic monitoring in place, with a pulse wave contour analysis- derived estimation of cardiac output (either calibrated or uncalibrated)
  • Decision made by clinicians to perform volume expansion through intravenous infusion of crystalloid fluid

You may not qualify if:

  • Pregnancy
  • Refusal to participate by relatives of the patient or the patient himself
