A proposito di questo titolo

In this episode, we break down BICARICU-2, a multicenter open-label randomized clinical trial of 4.2% IV sodium bicarbonate in critically ill adults with severe metabolic acidemia (pH ≤7.20) and moderate-to-severe AKI (KDIGO 2–3). We cover the physiology (why acidemia matters), the trial design (and what open label means for dialysis decisions), and the outcomes that should change bedside behavior. Bottom line: bicarbonate did not improve 90-day all-cause mortality (62.1% vs 61.7%), but it was associated with less kidney replacement therapy by day 28 (35% vs 50%). We close with a practical, conditional approach to when bicarbonate is reasonable as a temporizing strategy—and when it shouldn’t delay needed KRT.
