床旁超声监测下腔静脉在重症患者容量管理中的应用进展

Application progress of point-of-care ultrasound monitoring inferior vena cava in volume management of critically ill patients

确定哪些患者有容量反应性是重症监护病房中常被问到的问题之一,特别是在休克患者中。评估容量状态及容量反应性可帮助临床医护人员准确把握患者心脏前负荷功能,指导合理的容量管理,有助于改善患者的预后。为此,学者们提出了许多无创和有创的方法来评估容量反应性。下腔静脉超声因其简单、无创及可重复性好,目前已被广泛应用于指导重症患者的容量管理。本文就下腔静脉超声在重症患者容量管理中的临床应用进行综述,以期为重症患者的循环管理提供参考。

Determining whether patients have volume-responsiveness is one of the frequently asked questions in the intensive care unit,especially in shock patients.Evaluating the volume status and volume responsiveness can help clinical medical staff accurately grasp the patient's cardiac preload,guide reasonable volume management,and help improve patient prognosis.Therefore,many non-invasive and invasive methods have been proposed to evaluate volume responsiveness.Inferior vena cava ultrasound has been widely used to guide the fluid management of critically ill patients due to its simplicity,non-invasiveness,and good repeatability.This article reviews the clinical applications of inferior vena cava ultrasound in fluid management of critically ill patients,so as to provide a reference for circulatory management of critically ill patients.
