The AirSim Multi (ASM; developed and manufactured by TruCorp, Belfast, United Kingdom, a spinout from the Department of Anesthetics at the Queen's University in Belfast) is a new realistic and functional adult model for teaching and training the various airway management (AM) techniques recommended by practice guidelines for difficult AM. The key feature of the ASM is the life-like airway in which the reactions of the airway are virtually identical to those of a human patient. In order to ensure maximum realism, the main airway (including the tracheal carina and the bronchial bifurcation) has been created from computer tomography scans of a patient and moulded in one piece (manufactured from a soft polymere compound which gives a postive tactile feedback during and after insertion of the airway device).
The ASM can be used for indirect lifting of the epiglottis with Macintosh-type laryngoscopes and performs best (compared to other airway models) for training with a wide variety of currently available extra/supraglottic airway devices (1, 2), provided that a generous amount of a water-soluble lubricant is applied to the surfaces of the main airway and the airway device. The neck has a novel joint construction allowing a full range of extension and flexion movements. The full face and the movable jaw (the unique spring-loaded mandible allows maneuvers such as jaw thrust and mouth opening) facilitates realistic teaching and training in face-mask ventilation. The movable neck and jaw can be fixed in any position simulating limited airway access. The nasal passage (moulded in a manner similar to the main airway) allows nasal procedures (such as flexible bronchoscopy-assisted airway evaluation and nasotracheal intubation).
For many years, we used a standard airway model (the Laerdal Airway Management Trainer, Laerdal, Stavanger, Norway), with a main airway made of stiff plastic material, for teaching and training anesthesia residents, staff anesthetists, and anesthesia nurses in established and new techniques for AM. Although in use for only 3 months, the ASM became the model of choice (by novice users and exerienced instructors) for teaching and training purposes.
The acquisition costs of the ASM are about 1920 Euro (exclusive value-added taxes, according to the offer of the Austrian distributor, queried in December 2006).
