The novel technique of video laryngoscopy has been shown to improve glottic view and intubation success in the operating room. The aim of this study was to compare glottic view time of intubation and success rate of the McGrath Series 5 and GlideScope Ranger video laryngoscopes with the Macintosh laryngoscope by paramedics. Methods Thirty paramedics performed six intubations in a randomised order with all three laryngoscopes in an airway simulator with a normal airway. Subsequently every participant performed one intubation attempt with each device in the same manikin with simulated cervical spine rigidity using a cervical collar. Glottic view time until visualisation of the glottis and time until first ventilation were evaluated. Results Time until first ventilation was equivalent after three intubations in the first scenario. In the scenario with decreased cervical motion the time until first ventilation was longer using the McGrath compared to the GlideScope and AMacintosh p . The success rate for endotracheal intubation was similar for all three devices. Glottic view was only improved using the McGrath device p compared to using the Macintosh blade. Conclusions The learning curve for video laryngoscopy in paramedics was steep in this study. However these data do not support prehospital use of the McGrath and GlideScope devices by paramedics. Background Endotracheal intubation remains the
