PURPOSE OF REVIEW
To evaluate the existing evidence on the passive leg raising (PLR) test for fluid responsiveness prediction.
RECENT FINDINGS
It has been well established that either insufficient or excessive fluid administration derives in worse outcomes in critically ill patients, highlighting that a more accurate assessment of fluid management is required. Accordingly, several cardiovascular indices have been tested to improve our ability to predict patients' response to fluid loading at the bedside, the so-called functional hemodynamic monitoring. The standardized PLR is a relatively novel maneuver that, over the past 10 years, has repeatedly demonstrated high sensitivity and specificity for fluid responsiveness prediction.
SUMMARY
The current review underlines that PLR is an easy-to-perform and reliable method to assess fluid responsiveness. Its excellent performance is maintained even in many situations in which other dynamic predictive indices are not consistent and represents a valid alternative to the fluid challenge to avoid unnecessary volume administration.
目的综述
评估被动抬腿（PLR）试验预测液体反应性的现有证据。
最近的发现
已经充分证实，危重症患者给予不足或过多的液体都会导致更差的结局，这突出表明需要更准确地评估液体管理。因此，已经测试了几种心血管指数来提高我们在床边预测患者对液体负荷反应的能力，即所谓的功能性血流动力学监测。标准化的 PLR 是一种相对较新的操作，在过去 10 年中，它已经反复证明对液体反应性预测具有很高的敏感性和特异性。
总结
本综述强调 PLR 是一种易于实施且可靠的方法，可用于评估液体反应性。即使在其他动态预测指数不一致的许多情况下，其性能也很出色，它是避免不必要容量输注的液体挑战的有效替代方法。
