COVID Airways Podcast on Critical Care Scenarios

I was honoured to be invited back on the Critical Care Scenarios (@icuscenarios) podcast, to chat this time about airway management in COVID-19, but also talking about how it’s helping to focus improving our emergency airway management in general. Check it out at this link:

IAMM 2021: Access the International Airway Management Meeting content onliNe

This year’s International Airway Management Meeting was fully online, thanks for COVID, but SARS-CoV-2 certainly gave us lots to talk about. The meeting, held over 21-22 May, brought together 44 international experts for online presentations and very robust discussions, and had nearly 50 000 views online. The good news (if you missed it) is that the content is still fully available as an online recording (over 10 hours worth!), which you can access here:

The full program is below. You can watch the recording on my talk on “COVID Airway Management: Principles, Projects, Pet Ideas and Proper Evidence” below or by following this link.

Global Airway management in Unstable cervical Spine Survey (GAUSS)

Have you shared your preferences, practice and experience with managing the airway in patients with unstable cervical spine injuries? We have representation from around the world but would still like to expand our sample! If your country is not dark blue or green in the map above, please add your voice:

Airway ultrasound page launched

New content – we’ve added a static page to OpenAirway to build up a resource of #FOAM content on airway ultrasound. There is quite a lot out there on the great big interwebs, but this should form a kernel of good stuff to get you up to speed, or learn a few nuggets. Please comment on the page if you have additional sources or ideas to suggest. You can find the Airway Ultrasound page here.

In the process of collating material for the Airway Ultrasound resources here on OpenAirway, the great free e-learning courses on usabcd have come to light. After registering with the service, you can access the following freecourses (and even take the tests, generating a course certificate):

You’ll need to register, add the courses to your cart and then check out
(total fee 0.00) to gain access to the material. There are plenty of other modules, including FATE, FAST, lung ultrasound and TEE which can be accessed for a fee. Check it out!

Dual endoscopy demo

Here’s a brief clinical example of dual endoscopy using the CMAC VL and VS (video stylet).  This case was performed for teaching purposes, rather than a difficult airway.  Note the endoscopic view appearing as a picture-in-picture is from the editing; the images are on two separate displays.  (It starts a little late due to the author forgetting to press the record button on the device).

 

Dual endoscopy

“Dual endoscopy” refers to using two devices – usually a video laryngoscope and a rigid or flexible endoscope – to manage an airway.  The Bonfils (or Shikani or Levitan) optical stylet is often used in this context.  Performing dual endoscopy provides “three levels of protection”:

  1. If the glottic opening is easily seen with the laryngoscope, the rigid endoscope simply acts as an ideally shaped or steerable stylet to introduce the tube
  2. If the view is poor (CL grade 3 or 4), the laryngoscope can be used to guide the tip of the ETT and endoscope “into the ballpark”, and then the final positioning of the tip of the tube through the vocal cords is achieved with the endoscope.
  3. If the airway is badly soiled or swollen (eg. ongoing bleeding or angioedema), the endoscope can be used as a lightwand for a transillumination technique.  (Remember lightwands, anyone?)

Here’s a brief informal video explaining the first two points, using the CMAC VL/VS:

Another dual endoscopy approach is “VAFI” (video-assisted flexible/fibreoptic intubation), where a VL is used to help place a flexible endoscope, whereafter the rest of the intubation is continued using the flexible.  Several good case reports of this technique are described in the literature.
