Comparison of the Effectiveness of Bolus and Infusion Diuretic Therapy in the Management of Acute Heart Failure in Emergency Departments: a Randomised, Double-blind Clinical Study

Detailed Summary

Acute decompensated heart failure (ADHF) is a clinical syndrome associated with high morbidity and mortality rates. Current guidelines emphasize the importance of oxygenation and diuresis in the management of ADHF. However, there is no clear recommendation regarding whether diuretic therapy should be administered as intermittent bolus dosing or continuous infusion. The aim of this study was to compare the early efficacy of bolus versus continuous infusion diuretic therapy in the emergency department management of ADHF. In this single-center, prospective, randomized, double-blind, parallel-group clinical trial, patients aged ≥18 years presenting with ADHF and without known chronic kidney disease were randomized in a 1:1 ratio to receive either intermittent bolus therapy or continuous infusion therapy. Allocation concealment was ensured using opaque sealed envelopes. To maintain blinding, simultaneous placebo-like administrations were performed in both groups. The primary endpoint was total urine output at 2 and 4 hours. Secondary endpoints included changes in the internal jugular vein collapsibility index (JVCI) at 2 and 4 hours. Tertiary end point was spot urinary sodium at 2 and 4 hours.
