Sensitivity of total body electrical resistance measurements in detecting extracellular volume expansion induced by infusion of NaCl 0.9%

Fluid balance management in hospitalized patients is hampered by the limited sensitivity of currently available tools. The aim of this study was to assess the sensitivity of total body electrical resistance (TBER) measurements for the detection of extracellular volume (ECV) expansion. TBER and plasma resistivity (ρplasma) were measured during a 4-h infusion of NaCl 0.9% at a rate of 500 mL/h in 23 patients undergoing a diagnostic saline infusion...
