Outcome Measures

Primary Outcomes (1)

  • Occurrence of respiratory complications

    Respiratory complications are coughing, breath holding, laryngospasm, bronchospasm, and desaturation

    From the beginning of operation until 30 minutes after the operation

Secondary Outcomes (6)

  • Time of eye opening

    Within 30 minutes after the end of operation

  • Time to follow motor command

    Within 30 minutes after the end of operation

  • Time of LMA removal

    Within 30 minutes after the end of operation

  • Frequency of postoperative nausea and vomiting (PONV)

    Within 2 hours after operation

  • Changes of blood pressure during anesthesia

    Every 15 minutes, from the beginning of operation until 30 minutes after the operation

  • +1 more secondary outcomes

Other Outcomes (2)

  • Time to achieve a satisfied Modified Aldrete score

    Within 2 hours after operation

  • Number of Patients with high satisfaction to anesthesia

    At 12-24 hour after surgery

Study Arms (2)

Desflurane

EXPERIMENTAL

Desflurane group: The rule of 24 will be applied, which means that the fresh gas flow (l/ min) multiplied by volume percent of desflurane must not exceed 24. Therefore, once the patients return of spontaneous ventilation, an anesthesiologist turns on oxygen 1 l/ min, nitrous oxide 1 l/ min, and desflurane 12 vol% for 1-2 minutes. When the end-tidal desflurane reaches 3-3.5% (approximately 0.5 MAC), the anesthesiologist will decrease oxygen and nitrous oxide to each 0.5 l/ min and desflurane to 6 vol% (1 MAC). Desflurane concentration will be adjusted to maintain the end-tidal desflurane around 3-6% (0.5-1 MAC).

Drug: Desflurane

Sevoflurane

ACTIVE COMPARATOR

Sevoflurane group: The oxygen and nitrous oxide each 1 l/min will be turned on with sevoflurane 4 vol% for 1-2 minutes or until the end-tidal sevoflurane reach 1-1.2% (approximately 0.5 MAC). After that, the flow of oxygen and nitrous oxide is reduced to each 0.5 l/ min and concentration dial of sevoflurane is set to 2 vol% (1 MAC). During the operation, sevoflurane concentration will be adjusted to maintain the end-tidal sevoflurane around 1-2% (0.5-1 MAC)

Drug: Sevoflurane

Interventions

Desflurane is the volatile agent with low blood: gas partition coefficient (0.42), its uptake and elimination from the body of a patient are rapid, which results in a fast onset of anesthesia and a fast recovery from anesthesia. This property provides desflurane as an ideal agent for the ambulatory anesthesia. However, its pungent odor is concerned to irritate the upper airway and may cause significant respiratory complications.

Also known as: Des
Desflurane

Sevoflurane has a blood: gas partition coefficient of 0.65, which is slightly greater than desflurane. The major advantage over desflurane is the better scented. It is considered to be less airway irritation in LMA anesthesia with smooth induction and recovery.

Also known as: Sev
Sevoflurane
