Abstract

Diuretics are integral in fluid de-resuscitation of ICU patients following initial stabilization. While loop diuretics are commonly used, sequential nephron blockade (SNB) is an alternative diuretic strategy that combines a loop diuretic with at least one diuretic from another pharmacologic class to increase efficacy and limit adverse effects. The objective of this study was to compare the safety and efficacy of SNB to loop diuretics alone for de-resuscitation of critically ill patients. This retrospective study included adult ICU patients who received either a loop diuretic alone or combined with an aldosterone antagonist, carbonic anhydrase inhibitor, and/or thiazide diuretic on two consecutive days. The primary outcome was comparison of diuretic efficacy, assessed by urine output, on diuresis day 1. Secondary outcomes included comparison of diuretic efficacy on diuresis days 2-5 and incidence of acute kidney injury and electrolyte abnormalities on diuresis day 1. A total of 100 patients were included (SNB = 15, Loop = 85). At baseline, SNB patients had more hypernatremia (20% vs 2.4%,
