Investigating fluid responsiveness and venous congestion in critically ill patients during volume expansion

Dynamic Assessment of Fluid Responsiveness and Venous Congestion: Evolution of the VExUS Score During Volume Expansion

Observational Bicetre Hospital · NCT06772038

This study is testing how well critically ill patients respond to extra fluids and if they have too much fluid in their veins during treatment in the ICU.

What this trial studies

This observational study examines the relationship between fluid responsiveness and venous congestion in critically ill patients undergoing a standardized fluid challenge. It aims to understand how these two factors evolve over time following fluid administration, which is crucial for guiding fluid therapy in the ICU. By utilizing hemodynamic monitoring and pulse wave contour analysis, the study seeks to provide insights into the dynamics of fluid management in critically ill patients. The findings could enhance clinical decision-making regarding fluid therapy and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are critically ill patients aged 18 years and older who are hospitalized in the ICU and undergoing hemodynamic monitoring.

Not a fit: Patients who are pregnant or those whose relatives refuse participation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved fluid management strategies, reducing the risk of fluid overload and enhancing recovery in critically ill patients.

How similar studies have performed: Previous studies have indicated a relationship between fluid responsiveness and venous congestion, but this study's approach of incorporating a fluid challenge is novel and aims to fill existing knowledge gaps.
