Brief Summary

Precise assessment of postoperative volume status is important to administrate optimal fluid management. Bioelectrical impedance analysis (BIA) which measures the body composition using electric character. Extracellular water (ECW) ratio by BIA represented as the ratio of ECW to total body water (TBW) and is known to reflect the hydration status. Based on this, we aimed to determine whether aggressive fluid control using ECW ratio could improve clinical outcomes through a single blind, randomized controlled trial.

  • 28-day mortality rate

    Participants were followed upto 28th day after surgery

Study Arms (2)

Active fluid management with BIA monitoring

EXPERIMENTAL

For assessment of fluid status, a commercial portable BIA device (InBody M20®, InBody Corp., Seoul, Korea) was measured. Baseline BIA data were collected at the time of ICU admission, and BIA measurements were performed daily for 3days for all participants. 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 the investigators determined whether additional intervention was needed according to results of changes. These processes continued until the ECW ratio was within the normal range (0.390-0.406).

Drug: Active fluid management with BIA monitoring

Conventional fluid management without BIA monitoring

EXPERIMENTAL

For assessment of fluid status, a commercial portable BIA device with 5-kilohertz, 50-kilohertz, and 250-kilohertz alternating current (InBody M20®, InBody Corp., Seoul, Korea) was measured. Baseline BIA data were collected at the time of ICU admission. Thereafter, BIA measurements were performed daily for 3 days for all participants. The participants in conventional fluid management without BIA monitoring arm underwent conventional fluid management without specific targets of ECW ratio by BIA.

Interventions

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).
