简要总结
Ultrasound measurements of the inferior vena cava (IVC) have been proposed as a noninvasive tool to help guide fluid management. Well-established correlations exist between respiratory cycle-induced changes in IVC diameter and C entral Venous Pressure (CVP) . Beyond providing an estimate of CVP, the caval index, or percentage collapsibility of the IVC , has been proposed as a predictor of preload reserve. This noninvasive rapid measurement of CVP is especially important in critical care settings. It can help in differentiating hypovolemic, septic and cardiogenic shock. Changes in volume status will be depicted by change in the diameter of the IVC .
However, the validity and reliability of sonographic assessment of the inferior vena cava have been matters of controversy, and its applicability has been shown to be limited by technical difficulties. Recent study has shown a significant relationship between the internal jugular vein/common carotid artery (IJV/CCA) cross-sectional area ratio and CVP in pediatric burn patients .
