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

What this Trial Is About

Fluid responsiveness is an important factor that helps guide fluid therapy in critically ill patients. This research aims to better understand the relationship between fluid responsiveness and venous congestion, a condition where excess fluid causes pressure in the veins and can lead to worse health outcomes. The study focuses on how these factors change over time after giving a standardized fluid challenge to patients in intensive care. Patients in the intensive care unit who are monitored for heart function and have a clinical decision to receive intravenous crystalloid fluid will be observed. The study groups include those whose cardiac index increases by 15% or more after the fluid challenge and those who do not show this increase. The main goal is to compare changes in venous congestion, measured by the VExUS score, between these two groups immediately after and one hour following the fluid challenge. Participants will be closely monitored with hemodynamic tools before and after fluid administration. Researchers will assess the VExUS score for venous congestion changes at baseline, after 15 minutes, and again one hour later. This will help understand how fluid responsiveness affects venous congestion over time. The study is observational and will last until July 2025, involving adult patients aged 18 to 99 years who are receiving fluid therapy in the ICU.
