IV bolus versus continuous lasix for CHF

In this meta-analysis of randomized trials of inpatients with acute CHF exacerbations, lasix by continuous infusion resulted in greater weight loss (~0.8kg) and greater urine output (~240cc/day/100mg lasix) compared to IV boluses, but did not differ in urinary sodium excretion or length of stay. Due to lack of differences in clinical endpoints, deciding on bolus versus continuous infusions for now may be based on logistics (eg continuous infusion availability, cost, and convenience) (abstract).
