Implementation of Fluid Strategies Using Real-time Bioelectrical Analyzer in Surgical Intensive Care Unit (SICU)

The participants in active fluid management with BIA monitoring arm received fluid supplementation targeting specific range of ECW ratio by BIA (0.390-0.406). If a patient with dehydrated status indicated by the ECW ratio was less than 0.390, a bolus infusion was performed using 250ml of crystalloid fluid (PlasmaLyte). If a patient with overhydrated status indicated by the ECW ratio was more than 0.406, 10mg of furosemide was administered. Changes in the ECW ratio were measured at one hour after initial intervention for fluid adjustment, and these processes continued until the ECW ratio was within the normal range (0.390-0.406).

The participants in conventional fluid management without BIA monitoring arm underwent conventional fluid management without specific targets of ECW ratio by BIA.
