Thio, sux, cricoid etc. aren't magic. They were thought up by clever people, and new clever people get to think up the next version, and make it better. This is how things move on towards "optimal".

When we are so bound to the past we can't change, we perish, innit?

Fascinating

Although intubating while suctioning regurgitating gastric contents is likely to take up time/complicate intubation, & head down makes intubation more difficult while also decreasing apnoeic oxygenation time, unless you preoxygenate head up & then head down for intubation, which makes no sense.

*Sellick, not Selldinger

… it doesn’t replicate the same patient position & other variables at induction.

On balance, the marginal utility of cricoid pressure (in this position) is outweighed by its potential disadvantages. Seldinger’s cadaveric studies (in steep head down) have utility in demonstrating pressure is transmitted to the oesophagus, but..

In steep head up (should be standard) the most likely cause of regurgitation (in my patient population) will be active rather than passive. The mostly likely cause of active regurgitation is coughing, of which (in my experience) is well meaning, but premature application of cricoid pressure. (contd)

That would have made a very reassuring noise when sleeping at night.

Now you’re talking

Sounds like a great getaway

Vets in Australia do it pretty tough. I actually get the markup.

I do love the fact that over the years we've kept up with the science by going from "something something oil/gas partition" via "something something lipid bilayer" to "something something microtubules quantum mechanics"
