Study Arms:
- Sevoflurane, propofol, Nasal oxygen (Type: ACTIVE_COMPARATOR): After securing the IV, sevoflurane will be discontinued and a propofol infusion will be started at the dose of 300 mcg/kg/min depending on the child's age and neurologic status. A bolus of propofol will not be administered. Oxygen will be delivered via nasal prongs at 2 liters per minute. The infusion rate of propofol will be decreased to 250 after 15 min and then 200 mcg/kg/min also after 15 min. Supplemental IV boluses of Propofol (0.5 mg/kg) will be administered if the child moves or if signs of light anesthesia are noticed. The propofol infusion may also be increased in response to light anesthesia.
- Sevoflurane, Propofol, LMA (Type: ACTIVE_COMPARATOR): After securing the IV, weight appropriate LMA will be inserted and sevoflurane will be discontinued and a propofol infusion will be started at the dose of 300 mcg/kg/min depending on the child's age and neurologic status. Oxygen in air will be delivered via LMA. The infusion rate of propofol will be decreased to 250 after 15 min and then 200 mcg/kg/min after another 15 min. Supplemental IV boluses of Propofol (0.5 mg/kg) will be given if the child moves or exhibits signs of light anesthesia. The propofol infusion may also be increased in response to light anesthesia.
- Sevoflurane, sevoflurane, LMA (Type: ACTIVE_COMPARATOR): After securing the IV, weight appropriate LMA will be inserted and sevoflurane continued at 3% inspired concentration. Oxygen in air will be delivered via LMA at 2 lpm. The sevoflurane may be increased or decreased in 0.5% increments as needed.
- Sevoflurane, isoflurane, LMA (Type: ACTIVE_COMPARATOR): After securing the IV, weight appropriate LMA will be inserted , sevoflurane will be discontinued and isoflurane will be administered at 2 % inspired concentration. Oxygen in air will be delivered via LMA at 2 lpm. Isoflurane may be increased or decreased in 0.5% increments as needed.

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