IV Diuretics Appear Safe for Outpatient Heart Failure Treatment
Hospitalization reported as imminent for 52.8% of patients but observed rate is 31.7%.
(HealthDay News) -- Intravenous (IV) diuretics appear to be safe and effective for outpatient volume management in heart failure, according to a study published online in JACC: Heart Failure.
Leo F. Buckley, Pharm, from the Brigham and Women's Hospital in Boston, and colleagues examined the effectiveness of IV diuretic treatment for volume management in 60 patients with chronic heart failure and clinical evidence of worsening congestion. Patients received a bolus and 3-hour infusion of IV furosemide at an outpatient clinic. A standardized conversion algorithm was used to derive diuretic dosing from the maintenance oral loop diuretic dose.
The researchers found that the median daily loop diuretic dose was 240 mg oral furosemide or equivalent. For the entire cohort, the median urine output was 1.1 liters and 24-hour weight loss was 1.1 kg. For patients with varying maintenance diuretic doses and in patients with reduced or preserved ejection fraction, outcomes were similar. In 8.9% and 3.5% of patients, respectively, transient worsening of renal failure and hypokalemia occurred. Hospitalization was reported as imminent for 52.8% of patients although the observed rate of all-cause hospitalization at 30 days was 31.7%, with no deaths.
"Short courses of IV diuretics for volume management in patients with heart failure were safe and associated with significant urine output and weight loss across a wide range of maintenance diuretic doses and ejection fraction," the authors write.
