目的：评估被动抬腿试验（passive leg raising，PLR）后每搏量变异（stroke volume variation，SVV），即PLR-△SVV在自主呼吸感染性休克患者中容量反应的预测价值。方法：患者60例，用 PiCCO 监测 PLR和补液试验前后的血流动力学，补液试验后△SV（stroke volume）≥10％为容量反应组，评价PLR-△SVV预测容量反应的价值。结果：反应组PLR-△SVV明显变化[（10±4）mL vs （14±6）mL，P＜0．05]，无反应组无明显变化（P＞0．05）。 PLR-△SVV预测容量反应的ROC曲线下面积为0．881。以PLR-△SVV≥11．2％评价容量反应性，灵敏度为85．7％，特异度为92．0％。结论：PLR-△SVV可预测自主呼吸感染性休克患者的容量反应。

Objective To evaluate the value of PLR-△SVV for the septic shock patients with autonomous breathing. Methods 60 patients were included in the study. Hemodynamic data of PICCO were collected before and after treatment. After rehydration, the group (△SV≥10%) was defined volume responder group, and then the predictive value of PLR-△SVV was analyzed. Results Compared with the nonresponders group, PLR-△SVV was increased significantly in response group[(10 ± 4)mL vs (14 ± 6)mL,P<0.05]. The ROC curve for PLR-△SVV were 0.881, and the sensitivity was 85.7%, the specificity was 92.0%. Conclusion PLR-△SVV can be used to predict fluid responsiveness for septic shock patients with spontaneously breathing.
