  Purpose

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.


Condition Intervention
Apnea
Device: laryngeal mask Ambu AuraOnce
Device: laryngeal mask LMA Supreme

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Official Title: Ventilation With Laryngeal Mask Ambu Aura Once vs. Supreme in Children

Further study details as provided by Medical University Innsbruck:

Primary Outcome Measures:
  • Leakage pressure [cmH2O] [ Time Frame: 1min ] [ Designated as safety issue: Yes ]
    After ventilation has been established the leakage pressure will be measured, ie 1min after establishing ventilation


Secondary Outcome Measures:
  • Efficient ventilation [mL], [ Time Frame: 3min ] [ Designated as safety issue: Yes ]
    After ventilation has been established the efficient ventilation, tidal volume and stomach inflation will be measured, ie 3min after establishing ventilation

  • tidal volume [mL], [ Time Frame: 3 minutes ] [ Designated as safety issue: Yes ]
  • stomach insufflation [yes or no] [ Time Frame: 3 minutes ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Active Comparator: laryngeal mask Ambu AuraOnce
laryngeal mask Ambu AuraOnce
Device: laryngeal mask Ambu AuraOnce
airway management and mechanical ventilation with laryngeal mask
Active Comparator: laryngeal mask LMA Supreme
laryngeal mask LMA Supreme
Device: laryngeal mask LMA Supreme
airway management and mechanical ventilation with laryngeal mask

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.
