BASKA Mask Versus Endo Tracheal Tube in Gynecological Laparoscopic Surgery

A Prospective Randomized Comparison of the Effect of BASKA Mask Versus Endo Tracheal Tube on Respiratory Function Parameters in Patients Undergoing Gynecological Laparoscopic Surgery

The BASKA mask (Logikal Health Products PTY Ltd., Morisset, NSW, Australia) is a novel supraglottic airway device. It has many of the features of other supraglottic airways, with a number of innovations. These include; A non-inflatable cuff, that it is continuous with the central channel of the device. As the pressure increases with positive pressure ventilation, the cuff itself is 'inflated', this may improve the seal, reduce leak, and make ventilation more efficient.

The BASKA mask incorporates an inlet that fits into the upper esophagus, and the dorsal surface of the cuff is moulded to direct any oropharyngeal contents away from the glottis and towards the side channels to which suction can be attached to facilitate aspiration of this space (Fig.1c). These features may reduce the risk of pulmonary aspiration of secretions or gastric contents that accumulate in the supraglottic area.

Compared with previous versions, these modifications have made BASKA mask airway a fairly safe and effective airway device in low-risk patients undergoing gynecologic laparoscopic surgeries
