Association Between Venous Excess Ultrasound Grading System and Acute Kidney Injury in the ICU Population

Overview

Fluid resuscitation is one of the cornerstones of treatment in ICU patients. Nonetheless, excessive fluid administration can lead to fluid overload which has been associated with worse outcomes in the ICU. To prevent this, assessments of fluid responsiveness are commonly employed. However, fluid responsiveness does not take fluid tolerance into account. Fluid tolerance is the idea that a patient might still be fluid responsive but might already be at risk of the detrimental effects of fluid therapy. Recent developments in point of care ultrasound e.g. the Venous excess ultrasound might help identify patients at risk of fluid overload. However its association with patient relevant outcomes in the ICU remains unclear.

This study will investigate the association between the venous excess ultrasound grading system (VExUS) and patient relevant outcomes such as acute kidney injury, mortality and length of stay. A secondary analysis is planned where the association between VExUS and the lung ultrasound score will be investigated
