Figure 2From: Treatment of euvolemic hyponatremia in the intensive care unit by ureaEvolution of SNa in 35 patients with severe hyponatremia treated by urea and isotonic saline. (a) Daily evolution of SNa (mean ± SD) in 35 patients with severe hyponatremia (≤ 115 mEq/L) treated with isotonic saline and urea (*P < 0.001 compared to Day 0). (b) Daily evolution of SNa (mean ± SD) in 12 patients with severe hyponatremia (≤ 115 mEq/L) who received the first day only isotonic saline (1 or 2 L). The addition of urea increased significantly SNa (*P < 0.01 compared to Day 0). (c) Evolution of SNa (mean ± SD) each four hours in 10 patients with severe hyponatremia treated with 1 L isotonic saline over 12 hr and urea (0.5 g/kg) (P < 0.01 compared to time 0).Back to article page
