A clinical study of cardiac ultrasound combined with internal diameter respiratory variability of inferior vena cava in predicting volumetric reactivity in patients with sepsis in ICU
Objective:To investigate the clinical value of cardiac ultrasound combined with internal diameter respiratory variability of inferior vena cava in predicting volume reactivity in patients with sepsis in intensive care unit(ICU).Methods:60 patients with ICU sepsis who received treatment in our hospital from January 2021 to May 2023 were included in the study.Patients were grouped according to the results of volumetric load examination at admission.Patients with volumetric response were included in the volumetric response group(19 cases),and patients without volumetric response were included in the non-volumetric response group(41 cases).The Respiratory variability of inferior vena cava(RVI)was calculated by comparing the internal diameter of inferior vena(IVCDmax and IVCDmin)of the two groups.Cardiac ultrasound detection indicators[Stroke volume(SV),Cardiac output(CO),Heart Rate(HR),Mean arterial pressure(MAP)];Receiver operating characteristic(ROC)curve was used to analyze the predictive value of RVI and echocardiographic indexes for volume reactivity abnormalities in ICU sepsis patients.Results:IVCDmax and IVCDmin in volume-free group were lower than those in volume-free group,and RVI levels were higher than those in volume-free group(P<0.05).SV and CO levels in voluminous response group were lower than those in non-voluminous response group(P<0.05),and HR and MAP levels were not significantly different between the two groups(P>0.05).The area under the curve of volume reactivity of RVI,SV and CO by ROC analysis were 0.882,0.714 and 0.858,the sensitivity was 86.67%,84.00%and 85.77%,and the specificity was 86.67%,42.88%and 72.22%,respectively(P<0.05).Conclusion:Cardiac ultrasound combined with internal diameter respiratory variation of inferior vena cava has obvious clinical value in predicting volumetric reactivity in patients with sepsis in ICU,and can safely and effectively improve the accuracy of predicting volumetric reactivity in patients with sepsis in ICU.
