This prospective randomised crossover study was carried out to evaluate the performance and efficacy of the i-gel blind intubation (IGI) in airway management for pre-hospital trauma patients. Here, two blind intubation techniques were assessed (by 18 paramedics) using two supraglottic airway devices (IGI and LMA Fastrach) and a Macintosh laryngoscope (MCL).

LMA Classic, i-gel, PENTAX Airway Scope and Macintosh laryngoscope were all tested, with time to ventilation, intubation success rate and difficulty of intubation measured. Authors conclude that intubation with i-gel was faster and easier.
