Abstract

Objective: to describe the correlation of several hemodynamic parameters measured by PhysioFlow with corresponding parameters measured by PiCCO in septic shock patients. Methods: A prospective descriptive study on 32 patients with septic shock according to Sepsis 3 criteria. Patients were measured hemodynamic parameters by the thoracic impedance measurement technique (Physioflow) and corresponding parameters by PiCCO at the admission and during emergency management at at the A9 emergency center, Bach Mai Hospital. Study was carried out from from June 1, 2021 to August 15, 2022. Results: 32 patients were studied including 22 male patients (68.8%), and 10 female patients (31.2%), mean age was 60.8 ± 17.7 years old. CI measured by Physioflow (3.70±1.15 l/p/m2) and CI measured by PiCCO (3.71±1.34 l/p/m2) , SVRI measured by Physioflow (1955±941 ) d.s/cm5/m2) and SVRI measured by PiCCO (1933±1103 d.s/cm5/m2), SVI measured by Physioflow (32.8±10.3 ml/m2) and SVI measured by PiCCO (32 ,9±12.5 ml/m2 ). No statisticly significance was found between parameters measured by the 2 mothods. The hemodynamic parameters CI, SVRI, SVI measured by the Physioflow and PiCCO had a strong correlation and good agreement with r = 0.65 for CI, r = 0.84 for SVRI, r = 0.74 for SVI. Conclusions: The hemodynamic parameters measured by the thoracic impedance (Physioflow) are high accurate, which can replace the PiCCO for hemodynamic exploration on patients inh early septic shock stage.
