液体治疗是围手术期液体管理的重点、难点，过与不及都可对机体组织造成损伤。机体对液体反应性是指导液体治疗管理的重点。文章综述了目前预测液体反应性常用指标的基本原理、影响因素、不同手术中的应用价值和局限性，从而为患者围手术期合理的液体治疗管理提供依据，选择合适的液体反应性预测指标，作出及早诊断和处理。“,”Fluid treatment is an essential and difficult part of perioperative fluid management and excessive or deficient fluid treatment may result in injury to body tissues. The fluid responsiveness of the body is important for guiding the management of fluid treatment. The article reviewed the basic principles and influencing factors of the indicators commonly used to predict liquid reactivity, their application value and limitations in different operations, so as to provide evidence for rational treatment management of fluid responsiveness in the perioperative period, select appropriate fluid responsiveness indicators, and make early diagnosis and treatment.
