significant effect on the outcomes. Moreover, sample sizes were not calculated for between-group comparisons and therefore these data should be regarded as preliminary. Complications in eFONA, such as excess time, incision errors, tube misplacements, haemorrhage and cartilage injury, warrant adequate training and the upkeep of skill for this procedure. Since the correct identification of the CTM is recognised as the critical initial step, and since gaining confidence in one’s ability to correctly identify the CTM may decrease the barrier to perform cricothyroidotomy when indicated, we suggest that training with the F4L cadaver model contributes to a timely, correct application of cricothyroidotomy in the future.
