INTERVENTIONAL
Conditions
Summary
To investigate whether the inhaled anesthetic desflurane, compared with propofol, exerts cardioprotective effects and reduces the incidence of severe postoperative major cardiac events in patients undergoing coronary artery bypass graft (CABG) surgery.

Interventions
After routine induction, maintain anesthesia with inhaled desflurane , adjusting concentration as needed to sustain 0.5-2 MAC . To maximize the cardioprotective effects of inhaled anesthetics, adhere to this intraoperative strategy: Maintain ≥1 MAC continuous desflurane for ≥30 minutes ; For on-pump CABG , discontinue desflurane 15 minutes before initiating cardiopulmonary bypass (CPB) ; If intraoperative desflurane cessation is required, implement a wash-in/wash-out strategy (recommended but non-mandatory): Perform 3 alternating cycles of: Wash-in : ≥10 minutes of desflurane at ≥0.5 MAC, Wash-out : ≥10 minutes of complete cessation of inhaled anesthetics. Propofol is strictly prohibited for anesthesia maintenance throughout the procedure , except during CPB.
Administer total intravenous anesthesia (TIVA) using propofol infusion at 3-8 mg/kg/h . No inhaled anesthetics are permitted for maintenance. This may be delivered via:target-controlled infusion (TCI) systems, or manual adjustment of intravenous infusion rates.
