Laryngeal mask airway: uses in anesthesiology.
The laryngeal mask airway (LMA), developed in 1983, is a new device to assist in the management of the pediatric and adult airway. In 1991, the Food and Drug Administration gave its approval for use of the LMA in the United States. The LMA is reusable and appears to provide cost-effective airway management in numerous situations. The LMA is simple to use, atraumatic to insert, and helpful in overcoming an obstructed airway. Its role in management of the difficult airway and the traumatic airway is still evolving. This review will introduce the LMA to the nonanesthesiologist and review for the anesthesiologist the origins of the LMA, its physical structure, the technical aspects of insertion, problems with aspiration, its role in the difficult airway, and experience with the pediatric population.
