The Baska mask is a new supraglottic airway device . The investigators would like to assess its performance in setting in which the current standard - LMA device - is being used.

Condition Intervention Phase
Performance and Safety of a New Supraglottic Airway Device
Device: Placement and use of Baska mask
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Observational Study of Baska Mask, a New Supraglottic Airway Device

Further study details as provided by University College Hospital Galway:

Primary Outcome Measures:
  • Device Placement Success rate [ Time Frame: within 30 mins of anaesthesia commencement ]
  • time to placement of device [ Time Frame: within 30 mins of anaesthesia commencement ]
    from the moment the device touched until successful ventilation achieved or device removed

Secondary Outcome Measures:
  • airway leak pressure of the device [ Time Frame: within 30 mins of anaesthetic commencement ]
  • user-rated ease of insertion of device [ Time Frame: within 30 mins of anaestesia commencement ]
    10cm visual analog score to be used

  • complication rates [ Time Frame: From the moment general anaesthesia commenced up to 1 day postoperatively ]
    complications specifically monitored will be desaturation episodes, laryngospasm, blood staining of the device, lip damage. We will record other complications related to the use of the device, including but not limited to loss of airway with need to manioulate mask/switch to alternative device, regurgitation, aspiration, teeth damage.

  • patient comfort indices [ Time Frame: from the moment the patient awake up to 1 day postoperatively ]
    Throat pain, dysphagia and dysphonia will be assessed. 10 point verbal rating scale will be used

Enrollment: 30
Study Start Date: August 2011
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Baska Device: Placement and use of Baska mask
use of a supraglottic airway device as a standard part of a general anaesthetic
Other Name: Baska mask

Detailed Description:
Our group has performed a number of studies on novel airway devices. In this study we would like to evaluate a new supraglottic airway named Baska mask. We would like to monitor certain parameters (time to and ease of insertion, failure rate, seal pressures, complications etc) as regarding the performance and safety profile of this device. This is a descriptive case series of patients undergoing airway management under general anaesthesia.
