BACKGROUND: This unblinded randomised crossover study compares two endotracheal tube introducers (ETIs): the FROVA and the "Flexible Tip Bougie" (FTB), in an airway manikin mimicking difficult intubation with a percentage of glottic opening view of 30%. Participants were Emergency Medicine and Anaesthesia trainees with recent experience of less than twenty patient intubations. The primary outcome was time to intubation, further divided into time taken to pass the ETI and time to railroad the endotracheal tube (ETT) over the ETI. The secondary outcome was the difficulty of intubation. RESULTS: The median total time to ETT placement was significantly shorter with the FTB (37.5 s) compared with the FROVA ETI (63.0 s), P = 0.0006. The median difficulty reported (scores 0-10 with 0 being no difficulty) with the FTB was 2 compared with 5 for the FROVA, P < 0.0001. CONCLUSIONS: The FTB enabled significantly faster and easier placement of the endotracheal tube compared with the FROVA in inexperienced hands intubating a difficult intubation manikin.
