Low-Flow Desflurane vs Sevoflurane: Impact on Physiology and Recoveryand Recovery Profiles in Adult ENT Surgery

Sevoflurane will be administered via inhalation under low-flow anesthesia conditions. The concentration will be maintained at 2-3% (0.8-1 MAC) with a fresh gas flow of 1 L/min (50% oxygen and 50% air) after induction. Used in Group S (Sevoflurane Low-Flow Anesthesia Arm).

Desflurane will be administered via inhalation under low-flow anesthesia conditions. The concentration will be maintained at 4-6% (0.8-1 MAC) with a fresh gas flow of 1 L/min (50% oxygen and 50% air) after induction. Used in Group D (Desflurane Low-Flow Anesthesia Arm).
