Maintenance of anesthesia | Propofol | Sevoflurane |
RIPC | No | Three cycles of: 5 min inflation to 200 mmHg/5 min deflation |
Intraoperative blood glucose (BG) management | BG control every 60 min. Intravenous insulin infusion if BG greater than 180 mg/ml | BG control every 30 min. Intravenous insulin infusion if BG greater than 140 mg/ml |
pH level at the end of CPB, before aortic unclamping | pH ≥ 7.40 | pH ≤ 7.30 |
Gentle reperfusion | No | Gradual recovery of the CPB flow (initial recovery of the flow at 20% of the theoretical flow, with an increase of 20% every 30 s, until complete restoration in 2 min) |
