摘要: 精准评估患者容量状态对优化围术期及危重症治疗至关重要，锁骨下静脉塌陷指数(SCV-CI)作为一种基于超声的无创工具，通过测量呼吸周期中锁骨下静脉最大(呼气末)与最小(吸气末)直径的变化来评估容量状态及预测容量反应性。研究表明，SCV-CI在脓毒性休克、手术患者中展现出高预测价值，尤其适用于肥胖或腹胀等IVC测量困难的患者。其核心优势在于无创、简便、快速、可重复及经济高效。然而，其应用受呼吸模式、体位、深吸气动作及疾病病理生理状态等因素影响，最佳临界值及人群适用性仍需深入研究。本文将从多个方面综述SCV-CI在评估患者容量状态方面的临床应用价值及研究进展。
Abstract: Accurately assessing patients’ volume status is crucial for optimizing perioperative period and critical care. As an ultrasound-based non-invasive tool, the Subclavian Vein Collapse Index (SCV-CI) evaluates volume status and predicts fluid responsiveness by measuring respiratory variations in the maximum (end-expiratory) and minimum (end-inspiratory) diameters of the subclavian vein. Studies demonstrate that SCV-CI exhibits high predictive value in septic shock and surgical patients, particularly for those with difficult inferior vena cava (IVC) assessment due to obesity or abdominal distension. Its core advantages lie in being non-invasive, simple, rapid, reproducible, and cost-effective. However, its application is influenced by respiratory patterns, patient positioning, deep inspiration maneuvers, and pathophysiological conditions. Further research is needed to establish optimal cutoff values and population applicability. This article reviews the clinical value and research progress of SCV-CI in assessing volume status from multiple perspectives.
