Caval Aorta Index and Central Venous Pressure Correlation in Assessing Fluid Status! “Ultrasound Bridging the Gap”

Abstract EN

Accurate body fluid assessment and estimation of fluid status are essential in guiding fluid therapy in emergency setup.

This prospective cross-sectional descriptive study conducted to ascertain the effectiveness of inferior vena cava and aorta (IVC/Aorta) index in assessing the fluid status by comparing it with the central venous pressure (CVP).

Results showed the mean IVC/Aorta index in patients who had normal CVP range was 1.2 ± 0.12 SD, while in patients with low CVP, the mean index was 0.7 ± 0.09 SD, and, patients with high CVP, the mean index was 1.6 ± 0.05 SD.

In conclusion, the sonographic IVC/Aorta index assessment seems to be a quick, simple, noninvasive, and reliable method to access the fluid status in a busy setup like an emergency room.
