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.
