Abstract：Objective To discuss the application value of bedside cardiac ultrasound combined with passive leg raising (PLR) test in the assessment of capacity reactivity in patients with septic shock.Methods 61 patients with septic shock from October 2015 to October 2016 were objects of this study.Echocardiographic hemodynamic indices in horizontal position were detected.PLR and volume load test (VE) for patients were detected successively to detect the changes of echocardiographic hemodynamic indexes.The hemodynamic indices between the volume reactivity group and the nonreactive group were compared.Results 29 had capacity response in the 61 patients,accounting for 47.54％ (29/61).The baseline values differences of hemodynamics HR,MAP,CVP,SV and CO before PLR and VE of reactivity group and non-reactivity group were not statistically significant (P ＞ 0.05).After PLR and VE,the changes of HR and MAP between the two groups were not statistically significant (P ＞ 0.05).The two groups of CVP were all rising,compared with the baseline,the two groups were statistically significant (P ＜ 0.05).The two groups of SV values were also higher than the baseline;compared with baseline data,there was no statistical difference in non-reactivity group (P ＞ 0.05).Compared with baseline data,there was statistical difference in reactivity group (P ＜ 0.05).The corresponding SV value in the reaction group was higher than that in the non-reactive group (P ＜ 0.05).The two groups of CO were all higher than the baseline,but the changes in the non-reactivity group were not significant (P ＞ 0.05).And compared with baseline data,there was statistical difference in reactivity group (P ＜ 0.05).Pearson correlation analysis shows a positive correlation between PLR-ASV and dilatation of ASV (r =0.812,P ＜ 0.05).Conclusion Bedside cardiac ultrasound combined with passive leg raising test can be used for capacity reactivity in patients with septic shock.Its application effect is better and has certain guiding significance for clinical liquid treatment.
