What this trial studies
This multicenter survey collects information from ICU physicians across Swiss hospitals about their knowledge, attitudes, and practices with ultrasound-based fluid management. It compares familiarity with traditional methods like central venous pressure and IVC ultrasound to newer approaches such as the VEXUS score and dynamic tests for fluid responsiveness. The study uses an online REDCap questionnaire to capture demographics, training, experience, and institutional factors, with voluntary participation and electronic informed consent. Data will describe current practices and identify areas for improvement in ultrasound use for volume management and venous congestion assessment.
Why it matters
Potential benefit: Results could inform training and practice improvements to optimize ultrasound-guided fluid management in ICUs.
How similar studies have gone: Related surveys have mapped ultrasound use in critical care and helped identify practice gaps in several regions.

-
Carotid Doppler and echocardiography to predict fluid response in children with septic shock
We will test whether carotid Doppler ultrasound and echocardiography can tell which children with septic shock will respond to fluid treatment.
-
Right ventricular–arterial coupling during fluid loading in ICU patients
This study tests how the right ventricle handles fluid changes in critically ill adults to see how it affects blood flow and congestion.
-
How giving fluids changes tiny blood flow in critically ill patients with venous congestion.
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.
-
See if VExUS ultrasound can guide fluid decisions in ICU patients with venous congestion
We’re testing whether a bedside ultrasound score (VExUS) helps doctors in the ICU decide how much IV fluid to give to adults with venous congestion.
-
Venous congestion and delirium after heart surgery
This project will see if venous congestion during and after elective heart surgery is linked to a higher risk of postoperative delirium in adults who can complete cognitive testing.
-
Venous congestion and microcirculation after elective cardiac surgery
This project will try to see if bedside ultrasound signs of venous congestion (VEXUS score and femoral vein Doppler) are linked with microcirculatory problems in adults during their ICU stay after elective or urgent cardiac surgery.
