This study compared the decongestive effects of two isotonic infusion strategies: 5% glucose (for intravascular volume repletion only) versus 0.9% NaCl (providing additional sodium\/chloride supplementation), both added to protocolized diuretic therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>This single-centre, prospective, randomized, single-blind study included patients with fluid overload who were randomized 1:1 to continuous infusions (83.3\u2009ml\/h) of either 0.9% NaCl or 5% glucose for 48\u2009h. Co-primary endpoints included 24- and 48-h urine output, natriuresis within 48\u2009h, and total furosemide dose up to 48\u2009h. The NaCl group (n\u2009=\u200925) significantly outperformed glucose group (n\u2009=\u200925) in all co-primary endpoints: the median urine output was higher in the NaCl group versus glucose group at 24 and 48\u2009h (cumulative during 48\u2009h: 9500 vs. 7395\u2009ml, p\u2009=\u20090.001), the NaCl group had higher natriuresis during 48\u2009h of decongestion (p\u2009&amp;lt;\u20090.05), which was achieved with lower cumulative doses of furosemide (220 vs. 280\u2009mg, p\u2009=\u20090.02). The fractional excretion of lithium was higher in the NaCl versus glucose group (19.0\u2009\u00b1\u20098.9% vs. 14.7\u2009\u00b1\u20099.6%, p\u2009=\u20090.030), indicating inhibited proximal tubular sodium reabsorption. There was no difference in absolute distal reabsorption, but relative distal sodium reabsorption in the NaCl group was lower (86.9\u2009\u00b1\u200912.3% vs. 91.5\u2009\u00b1\u20099.3%,
