Dr. Abhilash Koratala from the Medical College of Wisconsin introduces VEXUS, or Venous Excess Ultrasound, for assessing hemodynamics and fluid status at the bedside in critical care and emergency medicine. He breaks down the components of VEXUS, including hepatic vein, portal vein, and intrarenal vein waveforms, and explains how they indicate venous congestion. Dr. Koratala emphasizes the importance of VEXUS in evaluating organ perfusion and its ability to provide additional information beyond traditional methods like Central Venous Pressure reading. He concludes by sharing a real-life case study where VEXUS helped guide diuretic therapy and monitor its effectiveness in treating venous congestion. This lecture provides valuable insights for healthcare professionals in managing patients with fluid overload and organ injury.
