Study Arms:
- Sevoflurane (Type: ACTIVE_COMPARATOR): In sevoflurane arm (n=20) at the beginning after successful intubation, 2 L/min nitric oxide (N2O), 2 L/min O2 , and 2% to 2.5% sevoflurane will be given for 10 minutes then total flow will be decreased to 2 L/min. Anesthesia will be maintained using 1-1.5 minimal alveolar concentration (MAC) of sevoflurane in 50% O2 and 50% N2O.
- Desflurane (Type: EXPERIMENTAL): In desflurane arm (n=20) at the beginning after successful intubation, 2 L/min N2O, 2 L/min O2, and 6% to 8% desflurane will be given for 10 minutes then total flow will be decreased to 2 L/min. Anesthesia will be maintained using 1-1.5 MAC of desflurane in 50% O2 and 50% N2O.

Based on this trial design, predict the completion outcome and termination type (if applicable).
