Laryngeal Mask Ambu Aura Once vs. Supreme in Children

Not Applicable

Withdrawn

• Conditions: Apnea

• Registration Number: NCT01718782
• Lead Sponsor: Medical University Innsbruck

Brief Summary

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.

Detailed Description

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.
