Laboratory comparison between patients with high (>6mEq/L) and normal strong ion gap (<6mEq/L) values in the hBE group
| Low SIG (N=20) | High SIG (N=16) | p value | |
| pH | 7.39 (7.37-7.39) | 7.40 (7.39-7.41) | 0.70 |
| PCO2 (mmHg) | 43.4 (40.00-46.70) | 37.60 (35.88-42.50) | 0.01 |
| Na (mEq/L) | 141 (137-144.8) | 139 (137.5-142.2) | 0.42 |
| Cl (mEq/L) | 106 (101.5-110.5) | 103 (100-106.5) | 0.17 |
| Albumin (mg/dL) | 3.5 (3.02-3.41) | 3.1 (2.85-3.50) | 0.09 |
| Lactate (mmol/L) | 1.38 (1.19-1.91) | 1.33 (0.97-1.67) | 0.35 |
| SIG (mEq/L) | 4.13 (2.75-5.20) | 8.37 (6.85-10.02) | <0.01 |
| SIDa (mEq/L) | 42.68 (38.83-45.74) | 43.45 (42.38-45.79) | 0.35 |
| SIDe (mEq/L) | 38.64 (34.75-40.97) | 34.90 (33.00-37.21) | 0.01 |
SIG - strong ion gap; SIDa - apparent strong ion difference; SIDe - effective strong ion difference. The results are expressed as the median (IQ) ± standard deviation.
