VExUS评分在重症患者液体复苏中的应用价值

The Role of VExUS Scoring in Guiding Fluid Management during Resuscitation of Critically Ill Patients

摘要: 液体复苏是重症患者管理中的核心环节，旨在维持足够的灌注压力并避免因静脉充血引发的器官损伤。当前，重症医学领域面临着液体管理策略不明确、个体化不足的问题。静脉超负荷超声评分(Venous Excess Ultrasound, VExUS)作为一种量化静脉充血的新兴工具，能够通过静脉超声评估液体耐受性，为液体管理提供重要依据。该文章总结了VExUS评分的技术原理，结合最新研究成果，探讨其在重症患者液体复苏中的应用前景，为临床医师提供基于VExUS的液体管理策略参考，从而优化重症患者的治疗效果，提升临床决策的科学性和有效性。

Abstract: Fluid resuscitation is a cornerstone in the management of critically ill patients, aimed at maintaining adequate perfusion pressure while avoiding organ injury induced by venous congestion. Currently, the field of critical care faces challenges in fluid management strategy, including a lack of clarity and insufficient personalization. The Venous Excess Ultrasound (VExUS) score is an emerging tool for quantifying venous congestion, capable of assessing fluid tolerance through venous Doppler ultrasonography, thereby providing critical guidance for fluid management. This article summarizes the technical principles of the VExUS score and, by integrating the latest research findings, explores its application prospects in fluid resuscitation for critically ill patients. It aims to provide clinicians with a VExUS-based reference for fluid management strategies, ultimately optimizing therapeutic outcomes and enhancing the scientific rigor and clinical effectiveness of decision-making.
