evaluation of renal function and BNP levels during loop diuretic infusion [ Time Frame: 180 days ] [ Designated as safety issue: Yes ]
this study aimed to evaluate the effects of continuous infusion of furosemide in comparison to twice daily regimens at similar doses with respect to changes in renal function in terms of creatinine levels and GFR, and BNP levels from admission to discharge

Loop Diuretics Administration and Acute Heart Failure
Continuous Versus Intermittent Loop Diuretics Infusion Dosing in Acute Heart Failure: Effects on Renal Function, Outcome and BNP Levels

Intravenous loop diuretics is the therapy most commonly used to treat pulmonary congestion and systemic fluid overload. In theory, continuous infusion should allow for a more consistent diuresis, avoiding the sodium reabsorption in the distal tubule as well as the neurohormonal activation. This should lead to renal function improvement and BNP decrease.

Probability Sample

consecutive patient sampling with diagonsis of acute heart failure, volume overload and needing for furosemide infusion

Acute Heart Failure
Drug: furosemide infusion
Patients were randomized in a 1:1 ratio to receive furosemide dose divided into twice-daily bolus injection (group 0) or continuous infusion (group 1)(mixed as a 1:1 ratio in 5% dextrose in water) for a time period ranging from 72 to 120 hours. The mean daily diuretic dosage was similar in the two groups. The median time from presentation to randomization was 16 hours, and the median duration of study-drug administration was 112± 24 hours
