Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Furosemide with spironolactone or hydrochlorothiazide
Furosemide with placebo
IV furosemide dosage will be adjusted according to the protocol as follows. Level 1: previous oral furosemide dose ≤80 mg/day; furosemide 80 mg IV bolus every 6 hours Level 2: previous oral furosemide dose 81-160 mg/day; furosemide 160 mg IV bolus every 6 hours Level 3: previous oral furosemide dose >160 mg/day; furosemide 250 mg IV bolus every 6 hours Furosemide dosage will be adjusted to keep urine output between 3,000 and 5,000 ml/day and >600 ml during 6 hours after furosemide administration. If the urine output <3,000 ml/day or <600 ml per 6 hours, furosemide dosage will be increase 1-level up per protocol above. If the urine output >5,000 ml/day, furosemide dosage will be reduced 1-level down per protocol above. Patients will be received spironolactone or hydrochlorothiazide in combination with intravenous furosemide according to patients' serum potassium levels.
IV furosemide dosage will be adjusted according to the pre-defined protocol as shown in the experimental group. Patients will be received spironolactone placebo or hydrochlorothiazide placebo in combination with intravenous furosemide according to patients' serum potassium levels.
