Fluid responsiveness and changes in venous congestion and lung water during volume expansion in critically ill patients: a multicentre observational study.

ABSTRACT:

Background

The relationship between fluid responsiveness and right-and left-sided congestion remains underexplored. This study aimed to delineate the dynamic behaviour of venous congestion and extravascular lung water index (EVLWI) during a fluid challenge depending on the concomitant changes in cardiac index (CI).

Methods

In patients from three intensive care units, for whom a 500-mL fluid challenge was administered, we retrospectively analysed CI, central venous pressure (CVP), venous excess ultrasound (VExUS), and EVLWI, which had been prospectively recorded. A VExUS congestion point was calculated from 0 to 7 by assigning 1 point to each degree of abnormality for the 4 investigated veins. A subgroup analysis was planned in patients with acute respiratory distress syndrom
