Brief Summary
The size selection of Laryngeal Mask Airway classic is usually followed the manufacturer's recommendation based on the patient's ideal weight. But sometimes the patient is tall and slim, the actual weight is much less than the ideal weight. This phenomenon might affect the success rate of insertion. Previous studies had demonstrated that the selection of Laryngeal Mask Airway size based on ideal weight could improve the success rate of insertion; therefore, this study was designed to prove whether this conclusion also applies to the tall and thin patients.

Six months
Study Arms (2)
Actual weight Group
EXPERIMENTALPatients in Actual weight Group: The selection of Laryngeal Mask Airway classic will be based on actual body weight, followed the recommendations of manufacturer (size 3 for weight \< 50 kg, size 4 for weight 50-70 kg, and size 5 for weight \> 70 kg ).
Ideal weight Group
EXPERIMENTALPatients in Ideal weight Group: The selection of Laryngeal Mask Airway classic will be based on ideal body weight, followed the recommendations of manufacturer ( size 3 for weight \< 50 kg, size 4 for weight 50-70 kg, and size 5 for weight \> 70 kg ).
Interventions
If there were any conflicts of the Laryngeal Mask Airway classic size selection in slim patients by the actual or ideal body weight, size selection will based on actual body weight in Actual weight Group while ideal body weight in Ideal weight Group.
