Prospective observational study demonstrates ultrasound scoring for intravascular volume status in ICU, suggesting clinical utility.

This study aims to evaluate the validity of an ultrasound-based numerical scoring system for assessing intravascular fluid volume.
Conducted in a surgical intensive care unit in an urban tertiary care teaching hospital.
Compared standard intravascular volume assessments with bedside ultrasound evaluations of cardiac function and other indicators.
Applied Fisher's exact testing and multinomial logistic model to analyze ultrasound scores and their accuracy.
Identified 18 patients (29.5%) as euvolemic, with 61.1% scoring 0 on the SAFE score.
SAFE score of -4 to -2 typically indicates hypovolemia, while -1 to +1 indicates euvolemia, and +2 to +4 indicates hypervolemia.
Statistical significance of findings reported with p < 0.001.
