摘要重症超声检查具有可视化、可重复、无创、实时动态监测等多方面的操作优势，目前已经被广泛应用于临床各类疾病的诊疗过程中。脓毒症是指宿主对感染反应失调导致的危及生命的器官功能障碍。在积极抗感染的基础上，早期给予液体复苏维持器官组织灌注，并个体化调整容量管理，是改善脓毒症患者预后及降低病死率的核心。目前临床上通常应用体格检查及静态参数来评估脓毒症患者的容量状态，存在诸多不足；而重症超声因其多元化的优点在脓毒症容量管理中具有诸多优势，并促进了重症医学的发展。本文对有关重症超声在脓毒症容量管理中应用的研究进展进行综述，旨在强调重症超声在脓毒症容量管理中的应用价值和局限性。

abstractsCritical care ultrasound has many operational advantages such as visualization, reproducibility, noninvasiveness, and real-time dynamic monitoring, and is now widely used in the treatment process of various clinical diseases. Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. On the basis of active anti-infection, early administration of fluid resuscitation to maintain organ tissue perfusion and individualized adjustment of volume management is the core of improving patient prognosis and reducing mortality. Currently, there are many shortcomings in the commonly used clinical physical examination and static parameters to assess volume status. Critical care ultrasound has many advantages in volume management of sepsis due to its diversified advantages, which promoted the development of critical care medicine. This article presents a review of critical care ultrasound in volume management in sepsis, aiming to highlight the value and limitations of the application of critical care ultrasound in volume management in sepsis.
