So this one is off the normal beaten track for me.
The original Scancrit post can be found here
The paper can be found here.
Here’s the rest of my thoughts on it:
This study was found by ScanCrit a while back now and generated a little bit of discussion on the twitter thingy.
Below are my notes on the study.
- sedated pigs with lots of monitors in place
- the common carotid monitor was of course proximal to where the LMA would be so i don’t know if this affects reading seeing as we’re interested in distal flow in the ICA and not the common or the ECA
- there’s some lovely stuff on the model they used
- they performed angios on pigs with the EGDs in to see how it affected things but these were on recently dead pigs which is surely a different thing altogether
- flow dramatically decreased when the EGD was placed
- they note that one study in anaesthesia showed reduced flow with EGD but it’s likely of little consequence there and very important in cardiac arrest
- of most importance is the fact the airway of a pig is shaped is so remarkably different that this may be entirely wrong.
- if it’s right however then reducing cerebral blood flow during a critically low flow period might be real bad news.

And here’s a GIF of the CT. Sorry if the scroll is a bit slow. HT to radiology signs for the link to the MakeAGif site.
