FloTrac/Vigileo系统与超声在评估脓毒症休克血流动力学相关性及对比研究
Correlation and Comparative Study of FloTrac/Vigileo System and Ultrasound in Assessing Hemodynamics in Septic Shock
摘要
Abstract
Objective To compare the effectiveness of ultrasound and the FloTrac/Vigileo system in evaluating fluid resuscitation in patients with septic shock.Methods From January 2023 to August 2024,80 patients with septic shock requiring mechanical ventilation admitted to the Intensive Care Vnit of our hospital were enrolled.All patients received early goal-directed therapy,followed by volume status measurements using ultrasound and the FloTrac/Vigileo system.Volume responsiveness was assessed by volume expansion(VE).Patients were divided into two groups based on stroke volume increase(△SV):the response group(△SV≥15%,n=38)and the non-response group(△SV＜15%,n=42).The parameters measured by ultrasound and the FloTrac/Vigileo system before VE were compared between the two groups.The correlations between these parameters and △SV were analyzed,and their predictive value for volume responsiveness was evaluated.Results Before VE,the central venous pressure(CVP)and inferior vena cava diameter(IVC-D)of the response group were lower than those of the non-response group,while the distensibility index of the inferior vena cava(dIVC),stroke volume variation(SVV),stroke volume variation before and after leg raising test(△SV-PLR)were higher than those of the non-response group,and the differences were statistically significant(P＜0.05).According to correlation analysis,CVP,IVC-D,dIVC,SVV,△SV-PLR before VE were linearly correlated with △SV(r values were-0.367,-0.630,0.788,0.936,0.942,all P＜0.05),and △SV-PLR had the highest correlation;ROC curve analysis showed that the area under the ROC curve(AUC)of CVP,IVC-D,dIVC,SVV,and △SV-PLR before VE were 0.404,0.160,0.683,0.829,and 0.860,and △SV-PLR had the highest predictive value,while CVP and IVC-D had no predictive value.Conclusion In patients with mechanical ventilation for septic shock,ultrasonic monitoring of dIVC and FloTrac/Vigileo system monitoring of SVV and △SV-PLR can effectively predict the fluid responsiveness of patients with mechanical ventilation septic shock,but △SV-PLR has the best specificity and sensitivity.关键词
