Of course the issue here is whether occlusion of the oesophageal entrance sufficient to prevent antegrade passage of a flexible silicon tube is a valid surrogate for the ability to prevent retrograde passage of liquid (ie. gastric fluid). There is a significant difference here and I feel this research adds little to the debate regarding benefit (or not) of cricoid pressure.

Interesting. One wonders how many blocks would be improved by the addition of dex. Cost:benefit analysis would be nice as (in my setting anyway) the cost of dex is prohibitive.
