Comparison of baseline biological characteristics and haptoglobin 3–5 days before the procedure and 1 day after the procedure
| Biological characteristics | Before procedure | After procedure (Day 1) | P-value |
|---|---|---|---|
| Haemoglobin (g/dL) | 14.5 (13.7; 15.4) | 12.9 (12.1; 14.2) | 0.0001 |
| Platelets (109/L) | 235 ± 58 | 193 ± 44 | 0.001 |
| Leucocytes (109/L) | 6.3 (5.2; 6.9) | 8.4 (7.4; 9.7) | 0.0001 |
| Haptoglobin (g/L) | 1.40 (1.20; 1.58) | 0.18 (0.04; 0.51) | 0.0001 |
| GFR (mL/min/1.73 m2) | 72 ± 20 | 80 ± 50 | 0.96 |
| Creatininemia (μm/L) | 73 (73; 104) | 80 (71; 102) | 0.32 |
| Urea (mmol/L) | 7.0 (5.6; 8.2) | 6.2 (5.4; 7.5) | 0.14 |
| Free haemoglobin (g/L) | / | 0.04 (0.02; 0.08) | |
| LDH (UI/L) | / | 374 (311; 445) | |
| Haemoglobinuria | / | 19 (28%) | |
| Total bilirubin (μm/L) | / | 24.5 (18.0; 36.0) | |
| Direct bilirubin (μm/L) | / | 10 (8; 12) |
All biological markers of haemolysis were not sampled before the procedure. Values are expressed as mean (SD) or median (quartiles: 25; 75).
GFR, glomerular filtration rate LDH, lactate dehydrogenase.
