摘要
容量管理是重症患者血流动力学治疗的重要组成部分,可帮助患者达到机体最适的心脏前负荷。液体复苏、肾功能不全等因素均可导致液体过负荷的形成。研究证明,容量高负荷对以心脏为首的全身各器官都会造成显著负面影响,而液体负平衡可减少并发症并改善重症患者预后。容量管理的最终目标是达到并且维持能满足适当组织灌注的最低心脏前负荷。连续肾脏替代治疗(CRRT)作为一种肾替代技术来清除体内过多的液体,具有快速、精确调整容量以及通过血流动力学相关指标连续评估容量状态等优势。
Fluid capacity management is considered an integral part of hemodynamic therapy in critically ill patients, aimed at maintaining optimal heart preload. Fluid overload attributes to fluid resuscitation and renal insufficiency. Recent studies have demonstrated that volume overload has significant negative impacts on multiple organs, especially heart; consequently, negative fluid balance can reduce complications and improve prognosis. The ultimate goal of volume therapy is to achieve and maintain a minimal heart preload appropriate for tissue perfusion. As a renal replacement therapy to remove excess fluid, continuous renal replacement therapy （CRRT） possesses incomparable superiorly, which can rapidly and accurately regulate volume and evaluate the volume state continuously through hemodynamic indexes.
