无创评估容量反应性的临床应用进展

容量评估与干预是围术期患者安全管理的一项重要因素，可以影响患者最终转归。无创评估容量反应性具有简便、快速、创伤小、患者更易配合等特点，是进行个体化液体治疗的基础，近些年临床应用广泛。本文从基于心肺交互作用的评估指标、基于容量负荷的评估方法两方面对常用的无创评估容量反应性的方法进行阐述，为临床应用提供参考。

Progress in clinical application of noninvasive methods for assessing fluid responsiveness

Volume assessment and intervention is an important factor in perioperative patient safety management, which affects the final outcome of patients. Non-invasive assessment of fluid responsiveness is simple, rapid, non-invasive, and easy for patients to cooperate, which is the basis of individualized fluid therapy. It has been widely used in clinical practice in recent years, but different monitoring indicators and methods both have strengths and weaknesses. In this paper, non-invasive assessment of fluid responsiveness will be described from the evaluation indexes based on cardiopulmonary interaction and the evaluation methods based on capacity load, which provides a reference for clinical application.
