Intraoperative aortic clamping time, priming and time on cardiopulmonary bypass circuit
| NP | HP | P-value difference between mediansa | Median difference between groups (95 % CI)b | |
|---|---|---|---|---|
| (n = 9) | (n = 11) | |||
| Aortic clamping time (min) | 35 (20–55) | 30 (18–46) | 0.71 | −2 (−14 to 8) |
| Time on CPB (min) | 59 (36–75) | 53 (37–83) | 0.37 | −7 (−17 to 8) |
| Priming CPB circuit: | ||||
| Erythrocytes (mL · kg−1) | 140 (100–260) | 130 (80–180) | 0.18 | −25 (−75 to 10) |
| Plasma (mL · kg−1) | 0 (0–25) | 0 (0–0) | 0.41 | 0 (0 to 0) |
| Albumin 20 % (mL · kg−1) | 50 (50–100) | 50 (50–75) | 0.77 | 0 (0 to 0) |
