I read an article recently published in Annals of Emergency Medicine. It leaves me a bit perplexed. I struggle to see what new knowledge it brings to the field.

Here’s what they did:

Patients having procedural sedation with propofol for minor surgical procedures like fracture reductions, abcess incisions, joint reductions and what-not were randomised into one of two groups. One group received supplemental higher-flow O2 on a rebreather mask five minutes before and during the procedure. The other group received room air throughout the same non-rebreather mask. Then they looked at how many patients developed hypoxemia, in this case meaning sats below 93%. The results are in the diagram below.

The article also discusses how this can be employed in pain management as well. A closely related yet different area, it’s uses are immediately apparent. The article went on to discuss the use of pure cbd oil for pain management, and how it seems to be in a controversial gray area for some, while proven, tried and true to yet another group. An article I found on the site anipots covered this topic well. So I guess what I’m saying is this seem to be gaining some traction, as well as media attention. It’s an interesting topic, and one I consider worth following.

They conclude that patients who get supplemental O2 are less likely to become hypoxaemic during the procedure.

So what they are basically saying is that pre oxygenation prevents hypoxemia and supplying the patient with oxygen cures hypoxemia.

We knew that. Right?
