Overview
Brief Summary
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
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)

Outcomes
Primary Outcomes
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 Outcomes
- insertion success rate of the device(within 30 min of anaesthesia commencement)
- device airway leak pressure(within 30 min of anaesthesia commencement)
- device insertion time(within 30 min of anaesthesia commencement)
- ease of insertion of device(within 30 min of anaesthesia commencement)
- complications(from the moment anaesthesia commenced up to the first postoperative day, an expected average of 30 hours.)
- Patient comfort(from the moment patient awake up to third postoperative day, an expected average of 80 hours.)
