The purpose of this study is determine safety and efficiency of mechanical ventilation in children with two different types of single use laryngeal masks (Ambu AuraOnce vs. LMA Supreme). The main interest is leakage pressure of oropharynx and stomach. The null hypothesis is that leakage pressures of Ambu AuraOnce and LMA Supreme are equivalent. The alternative hypothesis is that there is a difference in leakage pressure.
Before starting surgery patients will be anesthetised and airway managed either with LMA Ambu AuraOnce or Supreme. Ventilation parameters, stomach inflation, and hemodynamic parameters will be measured.

Leakage pressure [cmH2O]
After ventilation has been established the leakage pressure will be measured, ie 1min after establishing ventilation
Time frame: 1min
Efficient ventilation [mL],
After ventilation has been established the efficient ventilation, tidal volume and stomach inflation will be measured, ie 3min after establishing ventilation
Time frame: 3min
tidal volume [mL],
Time frame: 3 minutes
stomach insufflation [yes or no]
Time frame: 3 minutes
