ADVANCEMENTS IN THE CLINICAL APPLICATION OF INFERIOR VENA CAVA DIAMETER AND COLLAPSE INDEX IN ULTRASONOGRAPHY DURING ANESTHESIA

Abstract

Fluid management involves static and dynamic indicators. Static indicators include pulmonary artery wedge pressure and central venous pressure, whereas dynamic indicators include stroke volume variation, the inferior vena cava collapsibility index, the pulse perfusion variability index, pulse indicator continuous cardiac output, and Flotrac based on cardiac output. However, most of these techniques are frequently used in intensive care units owing to their combination of clinical characteristics, cost, invasiveness, anesthetic risk, procedure time, and operability. Concurrently, ultrasound techniques have recently received more attention from anesthetists because of their ease of learning and use and lower cost. This article discusses the clinical application of inferior vena cava diameter and blood vessel assessment intraoperatively during general anesthesia.
