RESUMEN
Objective:To evaluate the value of bedside ultrasound in evaluating volume responsiveness of patients with septic shock.Methods:A total of 102 patients with septic shock admitted to ICU of the First Affiliated Hospital of Hebei North University from April 2018 to February 2021 were selected. Patients were divided into response group and non-response group according to the value of stroke volume increase (ΔSV) after volume loading test (VE), and the hemodynamic parameters before and after VE were compared between the two groups. Pearson correlation was used to analyze the relationship between ΔSV and hemodynamic indexes. Receiver operating characteristic (ROC) curve was drawn to analyze the sensitivity and specificity of each hemodynamic index in evaluating volumetric reactivity in patients with septic shock.Results:Of the 102 patients, 54 responded and 48 did not. Before VE, the distensibility index of inferior vena cava (ΔIVC 1), espiratory variability index of inferior vena cava (ΔIVC 2), respiratory variability of aortic peak velocity (ΔVpeak AO), brachial artery maximum velocity variability (ΔVpeak BA) and respiratory rate of peak flow velocity of femoral artery (ΔVpeak CFA) in response group were higher than those in non-response group (all P<0.05), but there was no statistical significance in heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP) between 2 groups (all P>0.05). After VE, the HR, ΔIVC 1, ΔIVC 2, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA in response group were significantly decreased, while MAP and CVP were significantly increased (all P<0.05). The CVP was significantly decreased in the non-response group ( P<0.05), while other indexes were not significantly changed. Before VE, the ΔIVC 1, ΔIVC 2, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA were positively correlated with ΔSV ( r=0.589, 0.647, 0.697, 0.621, 0.766; all P<0.05). There was no correlation between CVP and ΔSV ( r=-0.345, P>0.05). Before VE, the area under the curve of ΔIVC 1, ΔIVC 2, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA were all >0.7, indicating high sensitivity and specificity. Conclusions:Bedside ultrasound monitoring ΔIVC, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA can better evaluate the volume response of patients with septic shock, and can provide a reference basis for clinical fluid resuscitation treatment.
