下腔静脉变异度评估容量反应性影响因素

The influencing factors of fluid responsiveness evaluated by inferior vena cava variability

休克是重症患者常见的病理生理状态,病死率高。液体治疗是治疗休克的重要手段之一,实施液体治疗的前提是确保患者具有容量反应性,下腔静脉变异度是临床上常用的容量反应性评价手段,具有简单、无创、易学等优点。目前已有多项研究对其影响因素进行探究,但部分影响因素的具体作用尚未完全明确。本文就评估下腔静脉变异度的影响因素与相关研究进展做一讨论。

Shock is a common pathophysiological condition in critically ill patients with a high mortality rate.Fluid therapy is one of the essential approaches in treating shock,with the prerequisite being the determination of the patient's fluid responsiveness.Inferior vena cava collapsibility index is a commonly used clinical tool for assessing fluid responsiveness,known for its simplicity,non-invasiveness,and ease of use.Several studies have investigated its influencing factors;however,the specific roles of some of these factors remain not entirely clear.This article provides a review of the influencing factors and research progress related to the assessment of inferior vena cava collapsibility index.
