目的：评估被动抬腿试验是否有助于预测液体反应性。设计：文献的非系统回顾。结果：被动抬腿已被用作内源性液体挑战，并经过测试可预测急性循环衰竭患者对液体的血流动力学反应。现在，使用能够实时测量收缩期血流量的方法可以在床边轻松执行此操作。被动抬腿导致降主动脉血流增加至少 10% 或超声心动图主动脉下血流增加至少 12% 已被证明可以预测液体反应性。重要的是，这种预测对于心律失常或自主呼吸活动的患者仍然非常有价值。结论：即使对于有自主呼吸活动或心律失常的患者，被动抬腿也可以可靠地预测液体反应性。该测试可能会越来越多地在床边使用，因为它易于执行且有效，只要通过实时测量心输出量来评估其效果即可。
Objective: To assess whether the passive leg raising test can help in predicting fluid responsiveness. Design: Nonsystematic review of the literature. Results: Passive leg raising has been used as an endogenous fluid challenge and tested for predicting the hemodynamic response to fluid in patients with acute circulatory failure. This is now easy to perform at the bedside using methods that allow a real time measurement of systolic blood flow. A passive leg raising induced increase in descending aortic blood flow of at least 10% or in echocardiographic subaortic flow of at least 12% has been shown to predict fluid responsiveness. Importantly, this prediction remains very valuable in patients with cardiac arrhythmias or spontaneous breathing activity. Conclusions: Passive leg raising allows reliable prediction of fluid responsiveness even in patients with spontaneous breathing activity or arrhythmias. This test may come to be used increasingly at the bedside since it is easy to perform and effective, provided that its effects are assessed by a real-time measurement of cardiac output.
