Podcast 184 – Needle Cric (Again) and Transtracheal Jet Ventilation with Laura Duggan - a podcast by Scott D. Weingart, MD FCCM

So we have discussed my preference for surgical over needle-based techniques for front-of-neck-access (FONA) many times on the podcast. You can see the needle vs. knife discussions in some of the earlier posts as well. Cut to air just works better in my opinion. If you'd like to see how I advocate you perform this procedure, come to the EMCrit Cric Page. This debate has heated up as the airway society of the UK has recently recommended scalpel-bougie cricothyrotomy as the first technique for FONA. Editorials explain why this decision was made. Currently, the Australians are still recommending needle-based techniques. So, to add gasoline to the debate, today I interview Laura Duggan, MD.



Laura completed residencies in both paediatrics and anesthesiology, as well as a cardiothoracic anesthesiology fellowship. She practiced for a time as a paediatric emergency physician in Canada. She now practices cardiac and general anesthesia at a level 1 trauma centre. In short, she is the perfect person to discuss these issues with. I got to chat with Laura at SmaccDUB about a paper she had just written on the high failure rate of transtracheal jet ventilation in can't intubate, can't oxygenate situations.

The Ventrain Device





I tested this device on the bench (no COI) and the reason I think it is the best of the crop is its active exhalation and the ability to monitor ETCO2. They sell it in kits with a proper cannula as well.

Other Jury-Rigged Techniques (None are Recommended)

3-Way Stopcocks are Probably Inadequate

Catheter or cath with 3-way stopcock is prob. inadequate for exhalation unless 13 seconds between breaths (Anaesthesia 2009;64:1353 and Pediatric Anesth 2009;19:452)

Use a Ventilator

Ventrain was the only device in this study that did not produce potentially injurious pressures, but ENK was pretty good and device below has not been tested
