Furosemide Stress Test to Predict Successful Liberation From RRT

The FST corresponds to the intravenous single-dose administration of 1 mg/kg (1.5 mg/kg in previously exposed patients) of furosemide and the assessment of resulting diuresis in the following two hours. In the 12 hours following the first RRT liberation, a FST will be performed. The test will be considered positive if urinary output is ≥200 mL in the two hours following furosemide administration.
