History of Changes
  Purpose

This study will evaluate the efficiency of the EcoAnesthesia mask and its advantages over the standard facemask used in our practice. The satisfaction by the anesthesia provider and its ease of use may change the standard practice in airway management. In addition to these additional effects on patient safety, the facemask is affordable and may reduce the environmental burden of anesthesia waste.


Condition Intervention Phase
Anesthesia Induction
 Device: EcoAnaesthesia facemask first
Device: Portex Adult (Standard) facemask first
Device: Portex Adult (Standard) facemask second
Device: EcoAnesthesia facemask second
 Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Crossover Assignment
Masking: Single Blind (Subject)
Primary Purpose: Health Services Research
Official Title: A Comparison of the Efficiency of the New EcoAnaesthesia Facemask With a Standard Facemask During Induction of Anesthesia

Further study details as provided by University of Louisville:

Primary Outcome Measures:
  • End-tidal oxygen concentration [ Time Frame: three minues ] [ Designated as safety issue: Yes ]
    End-tidal oxygen concentration after 3 minutes with the mask that the patient was first randomized to use.


Secondary Outcome Measures:
  • Maximum airway pressure [ Time Frame: End of 3 minutes with each mask ] [ Designated as safety issue: No ]
    Maximum airway pressure, which will be necessary to reach a tidal volume of at least 6 ml/kg every minute during the 3 minutes of mask ventilation with each device.


Enrollment: 40
Study Start Date: April 2010
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: EcoAnesthesia Mask first
Both the "standard adult facemask" (Portex Adult, USA) and the new facemask (EcoAnesthesia Mask, Intersurgical, Inc., Liverpool, NY, USA) will be tested in each patient for three minutes. The order of usage of each mask will be randomly assigned to each patient. This group will receive the EcoAnesthesia Mask first.
 Device: EcoAnaesthesia facemask first
The trial facemask will be used before the standard one.
Device: Portex Adult (Standard) facemask second
The standard facemask will be applied after the trial device
Active Comparator: Standard mask first
Both the "standard adult facemask" (Portex Adult, USA) and the new facemask (EcoAnesthesia Mask, Intersurgical, Inc., Liverpool, NY, USA) will be tested in each patient for three minutes. The order of usage of each mask will be randomly assigned to each patient. Patients in this arm will receive the standard mask first.
 Device: Portex Adult (Standard) facemask first
The standard facemask will be applied before the trial device.
Device: EcoAnesthesia facemask second
The trial facemask will be used after the standard one.
