摘要

摘要: 目的:探讨联合每博输出量变异度(SVV)及呼吸变异指数(RVI)在重症脓毒症患者容量反应性评估中的临床应用价值。方法:回顾性分析2012-01-2018-01期间在我院救治的50例脓毒性休克患者资料。所有患者进行补液试验,依据心脏指数变化值进行分组: ≥ 15%为反应组,<15%为无反应组,比较两组心率(HR)、平均动脉压(MAP)、中心静脉压(CVP)、SVV和RVI。结果:反应组RVI和SVV分别为(33.10±5.39)%和(16.13±4.55)%,明显高于无反应组(P<0.05);而反应组和无反应组HR、MAP和CVP比较差异无统计学意义(P>0.05);RVI和SVV诊断容量反应性的ROC曲线下面积分别为0.706和0.761(P<0.05),联合RVI及SVV诊断容量反应性的ROC曲线下面积为0.894(P<0.05)。结论:联合SVV与RVI可较好地评估机械通气脓毒性休克患者容量反应性,值得进一步深入研究探讨。

Abstract: Objective:To explore the value of stroke volume variation(SVV)and respiratory variability index(RVI)in the assessment of volume responsiveness in patients with severe sepsis. Method:Fifty cases of septic shock treated in our hospital from January 2012 to January 2018 were selected and analyzed retrospectively.All patients were tested with rehydration and assigned into two groups according to the changes of cardiac index,patients of cardiac index ≥ 15% were enrolled into reactive group,and patients of cardiac index < 15% were enrolled into non reactive group.Heart rate(HR),mean arterial pressure(MAP),central venous pressure(CVP),SVV and RVI were compared between the two groups. Result:The RVI and SVV in the reaction group were(33.10±5.39)% and (16.13±4.55)% respectively,which were significantly higher than those in the non response group(P<0.05).There were no significant difference in HR,MAP and CVP between the two groups(P>0.05).The area under the ROC curve of RVI and SVV for capacity reactivity was 0.706 and 0.761 respectively(both P<0.05)and the area under the ROC curve of RVI combined with SVV for capacity reactivity was 0.894(P<0.05).Conclusion:Combination of SVV and RVI may be effective in evaluating the volume responsiveness of septic shock patients with mechanical ventilation,which are worthy of further clinical investigations.
