Portal vein pulsatility index variation induced by the fluid challenge (%), defined by: Portal vein pulsatility index before the fluid challenge - portal vein pulsatility index after the fluid challenge.

研究概览

简要总结

Portal vein pulsatility index is a marker of venous congestion evaluated by point of care ultrasound. It is associated with acute kidney injury, especially in critically ill patients. It may be considered as a dynamic marker. The investigators hypothesized that portal vein pulsatility index is higher after a fluid challenge only in patient without preload dependence in critically ill patients with cardiovascular insufficiency.
