Determination of the Optimal Approach to Select the Best Size of BASKA Mask to Use in Male Patients

This study has been completed.

John Laffey, University College Hospital Galway
ClinicalTrials.gov Identifier:
NCT01625052
First received: March 23, 2012
Last updated: December 22, 2012
Last verified: December 2012
  Purpose
The investigators group has performed a number of studies on novel airway devices, including an observational study on the performance of a new supraglottic airway named Baska mask. In this new study the investigators wish to determine which criteria best predict the correct size of the Baska mask to be used in male patients

Condition Intervention Phase
Determination of the Best Predictor for Correct Baska Mask Size 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: Determination of the Optimal Approach to Select the Best Size of BASKA Mask to Use in Male Patients

Further study details as provided by John Laffey, University College Hospital Galway:

Primary Outcome Measures:
  • Determination of the best predictor for successful Baska mask size [ Time Frame: From the moment of preoperative assessment until the moment of mask placement, an expected average of 3 hours. ]
    We will evaluate the correlation between certain patient characteristics (including, but not limited, to actual and ideal body weight; height) and the size of the Baska mask used successfully in each patient.


Secondary Outcome Measures:
  • insertion success rate of the device [ Time Frame: within 30 min of anaesthesia commencement ]
  • device airway leak pressure [ Time Frame: within 30 min of anaesthesia commencement ]
  • device insertion time [ Time Frame: within 30 min of anaesthesia commencement ]
    the time from the moment the device is touched until successful ventilation is achieved or device is removed.

  • ease of insertion of device [ Time Frame: within 30 min of anaesthesia commencement ]
    we will use 10cm visual analogue scale

  • complications [ Time Frame: from the moment anaesthesia commenced up to the first postoperative day, an expected average of 30 hours. ]
    Complications during insertion, maintenance and removal and in the postoperative period (in PACU and next day follow up) List of complications (not exhaustive): desaturation episodes, loss of airway with need to manipulate mask/switch to alternative device, lip/teeth damage, regurgitation, aspiration, laryngospasm, blood staining on mask removal)

  • Patient comfort [ Time Frame: from the moment patient awake up to third postoperative day, an expected average of 80 hours. ]
    We will record throat pain, dysphonia and dysphagia using 10 point verbal rating scale.


Estimated Enrollment: 50

Study Completion Date: June 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Baska Device: Placement and use of Baska mask
use of Baska mask as component of standard general anaesthetic

Detailed Description:

Our observational study of the performance of the Baska mask suggests that this novel supraglottic airway has promise as an alternative to the current standard device, the laryngeal mask airway (LMA). Our results indicate that while the manufacturer weight criteria work reasonably well in females this may not be the case in males. The investigators wish to determine how well the manufacturer recommended sizing criteria for the Baska mask work in males.

This study is designed to determine which criteria best predict the correct size Baska mask to use in male patients. In addition the investigators will monitor the performance and safety of this device (insertion success rate, seal pressures, time to and ease of insertion, failure rate, complications etc)
