Abstract

Objective: To determine the correlation and agreement of various hemodynamic indices measured using the non-invasive Electrical Cardiometry (EC) method compared to the thermodilution (TD) method in septic shock patients. Methods: A prospective cross-sectional study was conducted in the Intensive Care Unit II at Viet Duc Hospital from March 2023 to September 2023. The studied indices included cardiac index (CI), stroke volume variation (SVV), and systemic vascular resistance index (SVRI). Thirty septic shock patients were simultaneously monitored hemodynamically using both methods, with 170 pairs of data points recorded at predefined time intervals. Results: The Pearson correlation coefficients (r) for CI, SVV, and SVRI measured by both methods were 0.848, 0.625, and 0.846, p < 0.001. Conclusion: CI, SVV, and SVRI measured by the EC method had good correlation and agreement with TD measurements in septic shock patients. The use of the EC method to monitor CI and SVRI to replace the TD method in clinical practice is appropriate. Currently, we do not recommend using the EC method to measure SVV to replace the TD method.
