AbstractIn a randomised, cross-over study, we compared the use of the Airtraq , Airway Scope and Macintosh laryngoscopes by paramedics for tracheal intubation in three simulated prehospital scenarios. Fifty-four paramedics were invited to take part. When evaluated in a difficult airway manikin, median IQR [range] time to intubation with the Airtraq (21 (16-37 [6-80] s) and Airway Scope (16 (5-75 [12-23] s) was shorter than that with the Macintosh laryngoscope (39 (25-54 [7-120] s; p < 0.0001). The success rate within 30 s was greater with the Airtraq (61%) and Airway Scope (93%) than with the Macintosh laryngoscope (22%; p < 0.0001). When used for a standard intubation and in the sitting position, we found minimal differences among the three laryngoscopes. We conclude that the Airway Scope and Airtraq have significant advantages over the Macintosh laryngoscope and that of the two, the Airway Scope is the more effective device to use in the prehospital environment.© 2010 The Authors.
