Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Congestion reduction (weight loss of 1.8 kg) is expected to be achieved, with daily weighing machine, during administration of the medication or placebo, according to randomization), by comparing weight before intervention and after the end of it. | — |
Secondary
| Measure | Time frame |
|---|---|
| A loss of 1.8 kg or a reduction of 30% of the NT-proBNP will be evaluated through a laboratory kit, before and after the intervention, in 3 days.;We will evaluate variation of BNP in 3 days (or discharge, if before) and at the end of hospitalization, through a laboratory kit, compared to values before the start of the intervention.;A 3-day creatinine variation (or discharge, if earlier) will be evaluated and at the end of hospitalization, using a laboratory kit, compared to values before the start of the intervention.;The need to use vasoactive drugs (sodium nitroprusside, nitroglycerin, dobutamine, milrinone) will be assessed over the study intervention days.;The congestion score (composed of 6 variables, each with a value of 1 point, being jugular, hepatojugular reflux, peripheral edema, crackling, third bulge, orthopnea) between the groups, before and after the intervention, will be evaluated.;The dyspnea score (Likert scale and area on the curve between Likert scale and time) will be evaluated between the groups, before the intervention and after.;The weight variation will be evaluated before after the intervention between the groups, through a weighting machine;The hospitalization time between the control and intervention groups will be evaluated.;Variation of hematimetric parameters (hematocrit and hemoglobin, by laboratory measurement) will be evaluated, before and after 3 days of intervention.;Hepatic function (TGO, TGP, bilirubin, alkaline phosphatase, gamma-GT, by laboratory measurement) will be assessed before and after intervention in both groups.;Re-hospitalization for decompensated heart failure (defined by the inclusion criteria of the present study) will be evaluated in 30 days (through telephone contact and / or patient chart review) in both groups.;Subjective site scale will be evaluated (value from 0 (no thirst) to 10 (intense thirst), in area on the curve - thirst x time) in both groups, before and after the intervention.;It will be assessed mort | — |
