Abstract

Objective: To analysis the correlation and aggrement of several hemodynamic parameters measured by the impedance cardiography (ICG) with corresponding parameters mesured by (PICCO) in septic shock patients at Bach Mai Hospital. Method: A prospective descriptive study on 32 patients with septic shock. Patients were measured hemodynamic parameters by the impedance cardiography (ICG) and PICCO at the same time. Study was carried out from November 2022 to November 2023 at the ICU and A9 Emergency Center - Bach Mai Hospital. Results: 32 patients were studied included 20 male patients (62,5%), and 12 female patients (37,5%), average age: 59.6 ± 19.76 years. The main cause of septic shock was pneumonia (50%), followed by gastrointestinal infections (25%) and cellulitis (9.4%), 56.7% of patients had chronic diseases and 66.7% of patients myocardial failure. The CI and SVRI indexes obtained in both methods are similar with the percentage of error (PE) being 27.9%, 30%, respectively, and a strong, statistically significant correlation throughout the study with the coefficient The correlations were r = 0.78 and r = 0.81, respectively, with p < 0.01. SVV index had a percentage error (PE) of 62.5% and correlation coefficient r = 0.84. Conclusion: The similarity and correlation of CI and SVRI measured between the two methods ICG and PICCO were acceptable in clinical practice, they can be used interchangeably to measure CI and SVRI. SVV measured from the two methods was less similar.
