Evaluation of four airway training manikins as simulators for inserting the LMA Classic™
Airway manikins have traditionally been used for teaching mask ventilation and tracheal intubation. There is an increasing need to use manikins for training in procedures such as insertion of the laryngeal mask airway. We have assessed four new airway training manikins (latest versions of the Airway Trainer™ (Laerdal, Norway), Airway Management Trainer™ (Ambu, UK), 'Bill 1'™ (VBM, Germany) and Airsim™ (Trucorp, Ireland)) as simulators for insertion of the LMA Classic™ laryngeal mask airway. Twenty volunteer anaesthetists inserted a size-4 laryngeal mask airway five times into each of the four manikins, in random order. Each insertion was assessed using objective and subjective tests. Subjective assessment varied widely but overall assessment indicated that the Airway Management Trainer was the poorest simulator for insertion of the laryngeal mask airway. The 'Bill 1' and Airsim manikins performed best as simulators for insertion of the laryngeal mask airway, although realistic ventilation with 'Bill 1' was not possible. © 2006 The Authors Journal compilation 2006 The Association of Anaesthetists of Great Britain and Ireland.
