Table 3 ICU and hospital mortality according to serum sodium concentration (SNa+) before and after the first renal replacement therapy (RRT) session.
From: Natraemia variations induced by acute dialysis in critically ill patients: a database study
Serum sodium levels (mmol/L) | Before 1st RRT N (%) | ICU mortality N (%) | Hospital mortality N (%) | After 1st RRT N (%) | ICU mortality N (%) | Hospital mortality N (%) |
|---|---|---|---|---|---|---|
Hyponatremia: Na+ ≤ 135 | 116 (53.9) | 43 (37.0) | 57 (48.3) | 42 (19.5) | 13 (30.2) | 19 (45.2) |
Mild: 130 ≤ Na+ ≤ 135 | 80 | 33 (41.2) | 39 (47.5) | 37 | 12 (32.4) | 16 (43.2) |
Moderate: 125 ≤ Na+ ≤ 129 | 26 | 10 (38.5) | 11 (42.3) | 4 | 1 (25.0) | 2 (50.0) |
Severe : Na+ < 125 | 10 | 0 | 7 (70.0) | 1 | 0 | 1 (100) |
Hypernatremia: Na+ > 145 | 8 (3.7) | 3 (37.5) | 3 (37.5) | 15 (7.0) | 0 | 6 (40.0) |
Severe: Na+ > 155 | 0 | 0 | 0 | 0 | 0 | 0 |
Normal sodium level: 135 < Na+ ≤ 145 | 91 (42.3) | 41 (45.1) | 41 (45.1) | 158 (73.5) | 74 (46.8) | 76 (48.1) |
