SHM Converge Scientific Abstract ePoster Gallery-Venous Excess Ultrasounography Captures Dynamic Volume Changes Surrounding Hemodialysis

Pdf Summary

This document describes research on Venous Excess Ultrasound Score (VExUS), a point-of-care ultrasound tool used to assess venous congestion by measuring the inferior vena cava and Doppler waveforms in the hepatic, portal, and renal veins. While VExUS has already been validated in patients with stable fluid status, its behavior during large fluid shifts had not been well studied.<br /><br />The study evaluated 31 patients with end-stage renal disease undergoing same-day intermittent hemodialysis (iHD). Researchers performed transabdominal VExUS and lung ultrasound before and after dialysis, and compared changes using paired t-tests. They also assessed B-line counts and subjective dyspnea.<br /><br />Results showed that iHD removed an average of 1.8 liters of fluid and was associated with a statistically significant decrease in VExUS grade by 0.65 (p = 0.005). Lung ultrasound also improved, with a mean reduction in B-lines of 1.1 (p = 0.002). Subjective dyspnea did not change significantly. The average patient age was 56.5 years, 61% were male, and average BMI was 25.9.<br /><br />The findings suggest that VExUS can detect dynamic volume changes during hemodialysis and may be useful as a bedside tool for guiding volume management. The authors note that future research should examine VExUS changes during diuresis to improve its accuracy and safety in hospital medicine. Current related projects include a biorepository study of plasma proteins in volume overload, a decompensated heart failure study, and research on VExUS changes in sepsis and septic cardiomyopathy.
