150 ED patients undergoing RSI in a single ED in Zurich were randomised to either C-MAC vs. DL.
For "ethical reasons" they excluded patients that they thought would be difficult to intubate. The primary outcome measure was first pass success rate. It was powered to find a 14% difference between the groups.
Unfortunately, all intubations were performed by one of three “very experienced” anaesthetic consultants.
Can you guess the first pass success rate for “very experienced” anaesthetists for simple intubations?
Yes, you guessed it… 100% in both groups. (Well, just about.)
This study was never going to find a difference and I wonder why they went to so much effort in the first place. Seems like it was always going to be a waste of time.
We already know that video laryngoscopes are taking over. But what do you do when the scope fails, unavailable, or needs rescue?

Dr Brian Doyle is an emergency physician originally from the United States but now very much calls Tasmania his home. Unfortunately, it will now be a bit more difficult to deport him from the country as he passed his Australian citizenship test a few years ago. (He was able to answer that Phar Lap won the Melbourne rather than the Davis Cup). His main interests are mostly the clinical aspects of emergency medicine but also in education, ultrasound and critical appraisal of the literature. He spends much of his time annoying people to help out with conferences.
