Abstract:
Objective:The hemodynamic parameters of elderly patients with septic shock were measured simultaneously with pulse index continuous cardiac output(PiCCO)and thoracic electrical bioimpedance(TEB)to evaluate the accuracy of TEB and to provide empirical evidence for its clinical use.Methods:A total of 24 elderly patients with septic shock admitted to the intensive care unit of our hospital between July 2021 and December 2021 were retrospectively recruited.TEB and PiCCO hemodynamic monitoring were performed continuously in all patients, and hemodynamic data were collected for statistical analysis.Results:Cardiac output, cardiac index, stroke volume, stroke index and systemic vascular resistance measured by the two methods had no significant difference( P>0.05). The 95% confidence intervals in the Bland-Altman plots for cardiac output, CI, stroke volume, stroke index, and systemic vascular resistance were(-1.18, 1.25), (-0.65, 0.71), (-24.23, 37.00), (-12.93, 19.26)and(397.11, 425.83). In the Bland-Altman plots for cardiac output, cardiac index, stroke volume and systemic vascular resistance, 4.17% of the points(1/24)fell outside of the 95% confidence interval, and in the Bland-Altman plots for stroke index, 8.33% of the points(2/24)fell outside of the 95% confidence interval. Conclusions:TEB and PiCCO have good consistency in evaluating the hemodynamics of elderly patients with septic shock.Therefore, TEB can be recommended for community hospitals and used in elderly patients.
