The Laryngeal Mask Airway (LMA(TM))was developed in the 1980s, but has only
recently begun to be used in Emergency Medicine. The LMA affords effective
assisted ventilation without requiring endotracheal intubation or visualiz
ation of the glottis, In doing so, it is more efficacious than a bag-valve-
mask apparatus, although the risk of aspiration of gastric contents persist
s, particularly if the device is not properly plated, The LMA also has sign
ificant potential utility in management of the difficult airway. Most repor
ted clinical experience with the LMA has come from the operating room. This
article provides an overview of the extensive potential utility of the LMA
in the Emergency Department and prehospital settings as well as a comprehe
nsive review of the pertinent advantages, disadvantages, and complications
associated with its use. (C) 2001 Elsevier Science Inc.
