Strengths
Whilst comparison of the effectiveness of the common methods have been tested in other studies, most studies have only compared 2 methods [2,7,10,15,17–19]. Our study compares 3 different teaching methods with appropriate statistical contrasts. Furthermore, despite being widely recognised and used as a teaching method in clinical practice, only one study has tested the effectiveness of the nose method[7]. Our study sample was a good representation of staff routinely involved with cricoid pressure application from theatres and ICU and included a range of doctors and nursing anaesthetic assistants of different experiences and backgrounds across 2 different hospitals. Although the sample was opportunistic rather than random, we believe it is representative of those routinely performing cricoid pressure.
