Limitations and Problems of Supraglottic Airway Devices

Abstract

Supraglottic airway device（SGD）is reported as the most popular device for emergent airway management in airway management guidelines such as the DAS guideline, DAM guideline and JSA airway management guideline. However, we rarely use the SGD when we perform emergent airway management.

The reason is that the SGD has limitations and problems. The limitations are that it is difficult to ventilate after an insertion of the SGD in patients who are male, aged 45 or older, have short thyromental distance, or limited neck movement. The problems are that we are worried about whether the SGD is a more effective ventilation than the endotracheal tube.

We do not know anything about the SGD.
