Comparative study of intravenous diuretics therapy-bolus versus infusion regimen in acute decompensated heart failure

Abstract

Background: Heart failure (HF) is a growing problem worldwide; more than 20 million people around the world are affected. The objective of the study was to compare the effect of different modes of administration of intravenous diuretic –bolus versus infusion, in acute decompensated heart failure in relation to diuresis and electrolyte balance.Methods: This prospective study was conducted in Darbhanga Medical College and hospital, Laheria sarai between October 2014 to November 2016. Patients of acute decompensated heart failure attending medical emergency ward and Intensive care unit of medicine department of Darbhanga Medical College and hospital, Laheria sarai were selected and grouped randomly as per inclusion and exclusion criteria.Results: The main findings of our study were greater diuresis in the first 24 h of admission with bolus dose. No difference in serum sodium or serum potassium levels between the groups.Conclusions: All three modes of diuretic therapies can be practiced with no difference in worsening of electrolyte levels. Bolus dose administration with its rapid volume loss might be a more effective diuretic strategy in our country with limited health resources.
