76. What makes “awake” such a good approach? www.airwaymanagement.dk Aziz M, Kristensen MS, Anaesthesia 2020:

77. awake anaesthetised & Paralyzed Advantages Open airway preserved Y n Spontaneous breathing preserved Y n Easier to localise glottic opening (air bubbles) Y n Easier to intubate (oropharyngeal axis) Y n The patient can help Y n The patient can be sitting Y n Some protection against aspiration Y n Observing patients neurological status Y n Allows decision making (intubate or not?) DURING the endoscopy y n Avoid cardiovascular depression Y n Dis-advantages Airway narrowing due to local anaesthetics Y n Cardiovascular stimulation Y n Patient dis-comfort? ? n More time consuming? ? n Aziz M, Kristensen MS, Anaesthesia 2020:

204. TTJV not Recommended in Emergency CICO Situations Transtracheal jet ventilation in the ‘can’t intubate can’t oxygenate’ emergency: a systematic review. L.V. Duggan, et al. BJA, Volume 117, Supplement 1, 2016, Pages i28-i38. Device failure in 42% of emergency CICO cases 51% rate of complications in emergency vs. 8% in elective anesthesia Barotrauma in 32% of emergency cases

205. • “Failed Airway” phrase stigmatizes procedure • The surgical airway—a small neck incision— should be viewed in larger context of patient care issues • “To save a life..sometimes you need a knife!” • Attempt to oxygenate during procedure; 100 seconds to ventilation—must begin before the patient is dead Surgical Airway ≠ “Failed Airway” Surgical Airway ≠ Rescue Airway

206. • Fluids are the enemy of everything • High-volume fluids (blood, vomitus) can prevent every means of visualization and oxygenation • High-volume fluids make every means of intubation—except cric—very challenging • Distorted midface and upper airway may preclude use of HFNC, mask, & SGA (supraglottic airway) Surgical Airway NOW! Dynamically Deteriorating with Distorted Anatomy and Fluids

207. Common Misperceptions and Errors with Surgical Cric • Lack of anatomic insight creates fear about using a scalpel—either cutting too deeply, or too far laterally • Operators are hesitant to start the procedure if they haven’t identified the cricothyroid membrane (misbelieving this is the 1st step) • Misperception of surgical skill needed to do the procedure causes delay in starting, and makes many operators “more comfortable” using a percutaneous technique

208. Operator Mindset 5 Mantras of a Surgical Cric • “To save a life, I need to use a knife” • “The laryngeal handshake will find midline” • “I will find the CTM—after—the vertical, midline skin incision” • “I am not a surgeon, but I can stabilize my hand on the patients sternum.” • “The cartilaginous cage will protect.”

219. Localizing CTM with fingertip often fails, and delays start Fingertip palpation is a fine motor skill in setting where most operators will have elevated heart rates CTM identification is difficult through skin and adipose If operator cannot locate CTM, they are mentally defeated at outset

227. • Dominant hand holds the scalpel; low grip on scalpel, like holding a pencil • Base of scalpel hand rests on patient’s sternum throughout the entire procedure—making both vertical skin and horizontal CTM incisions • Operator should be at the patient’s side, at shoulder, on the same side as operator’s dominant hand Ergnomics of Surgical Cric Cutting hand sternal stabilization Non-dominant hand laryngeal handshake from start to finish

228. • Always insert finger tip in the hole after CTM incision • Verifies entrance into airway • Verifies size of hole is adequate for tube • Some advocate bougie insertion alongside finger; It’s OK to use bougie, but never omit finger tip insertion to verify hole size • Most common mistake in open cric procedure is too small a hole, then passing a bougie or tube into subcutaneous location (same error common with chest tubes) Scalpel > Finger > Tube or Scalpel > Finger > Bougie > Tube

229. Non-Dominant Hand Position & 2nd Digit Movements Fingertip verifies CTM location after vertical skin incision 1st & 3rd digits grab thyroid Hand in same position Verifies hole size after horizontal skin incision

233. • Verify depth. Bifurcation of trachea is ~ 11 cm from cords—and insertion point is below the cords to start • Over-insertion causes hyper-inflation, tension physiology • Tension pneumothorax can occur from air dissecting through tissue planes • Secure tube securely Post-Surgical Cric: Depth of Tube & Pneumothorax
