Extreme vagal manoeuvres, Star Trek style translator apps and lignocaine magic all feature in this month's discoveries. Bex whips through the latest CMACE report, Frank reviews the evidence for ECMO and Mark tells us which drugs he'll be using for RSIs in 2012. Rik uses the new alcohol AUDIT tool to see who's been over-indulging this festive season and makes up this month's bunkum in the bath.
