Expérimental: 30 degree rotated lateral position
19 patients American Society of Anesthesiologists (ASA) class I or II aged 2-8 years undergoing tonsillectomy surgery were randomized to the head in 30 degree rotated lateral position.
The end-tidal (ET) sevoflurane concentration used for each patient was determined using the Dixon's up-and-down method.
The ratio of the end-tidal to predetermined end-tidal concentrations was maintained at 0.95-1.0
for at least 10 minutes to establish equilibration before device insertion was attempted.
The first patient received a 5.0% sevoflurane concentration and the step size of increase/decrease was 0.5%.

38 patients American Society of Anesthesiologists (ASA) class I or II aged 2-8 years undergoing tonsillectomy surgery were randomized to either the patient's head in the neutral position or 30 degree rotated lateral position.
The end-tidal (ET) sevoflurane concentration used for each patient was determined using the Dixon's up-and-down method.
The ratio of the end-tidal to predetermined end-tidal concentrations was maintained at 0.95-1.0
for at least 10 minutes to establish equilibration before device insertion was attempted.
The first patient received a 5.0% sevoflurane concentration and the step size of increase/decrease was 0.5%.

minimum alveolar anesthetic concentration of endotracheal intubation
Délai: The sevoflurane concentration is obtained when tracheal intubated immediately.
|
To compare the minimum alveolar anesthetic concentration of endotracheal intubation required for different head position in children with obstructive airway.
|
The sevoflurane concentration is obtained when tracheal intubated immediately.

|---|---|---|
|
intubation score
Délai: The intubation score is obtained when tracheal intubation was inserted immediately.
|
One nurse, who was blinded to the anaesthetic concentration, classified responses by the patient to tracheal intubation as either "movement" or "not movement".
Assesment was made for jaw relaxation and graded with intubation score.
The sum of intubation scores >4 was defined as a failure of insertion.
|
The intubation score is obtained when tracheal intubation was inserted immediately.
|
|
blood pressure include systolic and diastolic in mmHg
Délai: Baseline and every 1 minutes until 10 minutes after insertion of the endotracheal intubation.
|
To compare the evolution of blood pressure include systolic and diastolic during different head position group.
|
Baseline and every 1 minutes until 10 minutes after insertion of the endotracheal intubation.
|
|
heart rate in bpm
Délai: Baseline and every 1 minutes until 10 minutes after insertion of the endotracheal intubation.
|
To compare the evolution of heart rate during different head position group.
|
Baseline and every 1 minutes until 10 minutes after insertion of the endotracheal intubation.
|
|
bispectral index(BIS), number from 100 (awake) to 40-60(anesthetic status)
Délai: Baseline and every 1 minutes until 10 minutes after insertion of the endotracheal intubation.
|
To compare the evolution of of bispectral index values during different head position group.
|
Baseline and every 1 minutes until 10 minutes after insertion of the endotracheal intubation.
