Trial Summary

What is the purpose of this trial?

The RADAR-Canada trial is a pilot RCT undertaken to assess the acceptability of, compliance with, and biologic consequences of a deresuscitation protocol designed to expedite the removal of excess interstitial fluid in patients who remain in a positive fluid balance following admission to an intensive care unit (ICU).

Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Active deresuscitationExperimental Treatment2 Interventions
* Fluid minimization: clinical and research teams will review all intravenous orders and attempt to reduce fluids to 10-15 ml/hr. * Active deresuscitation: * Administer bolus furosemide 0.5 mg/kg bid or tid * Target daily negative fluid balance as follows: Calculated positive balance: \< 3 liters -600 - -800 ml/24 hours 3-6 liters 0.8 - 1.2 liters/24 hours 6- 10 liters 1.2 - 2.0 liters/24 hours \>10 liters \>2.0 liters/24 hours * If bolus furosemide fails to achieve these goals, results in hypotension or tachycardia, or at the discretion of the attending intensivist, start furosemide infusion titrated on an hourly basis to achieve above goals * If single agent ineffective, consider addition of metolazone
Group II: Usual careActive Control1 Intervention
Care at the discretion of the attending team.
