Objectives: To compare the performance of the perilaryngeal airway and the laryngeal tube in anaesthetized, paralyzed and ventilated adults having ophthalmic surgery.

Methods: Two hundred adults were randomly allocated to receive either the perilaryngeal airway or the laryngeal tube for airway management during general anesthesia. Ease and number of insertions, insertion time, oropharyngeal leak pressure, hemodynamic response to insertion, oxygen saturation and end-tidal CO2 during and after anesthesia were recorded.

Results: In the laryngeal tube group vs. the perilaryngeal airway group, insertion was considered easy in 90 vs.75, slightly difficult in 6 vs. 13, obviously difficult in 4 vs. 12 patients. In the laryngeal tube group, the device insertion was 96% successful on the first attempt as compared to 88% in the perilaryngeal airway group. The cumulative insertion success rate increased to 100% for both devices after a second attempt. The time required for the insertion of the perilaryngeal airway was slightly longer than that of the laryngeal tube, but it did not reach statistical significance. The airway leak pressure was significantly higher in the perilaryngeal airway group in comparison to the laryngeal tube group.

Conclusion: The perilaryngeal airway has insertion characteristics similar to the laryngeal tube but provides better airway sealing pressure. The perilaryngeal airway is a good addition to the airway armamentarium, and might be an important alternative for airway management.
