#8 Crash Cricothyrotomy• Learning Objectives
– Review• Prep
team/plan/room/equipment• Discuss Difficult Airway
Algorithm• Describe a “Crash Airway”• Declare: Can’t Intubate,
Can’t Oxygenate!
– Surgical Cric• Locate equipment• Double Setup• Proper technique
– Scalpel– Bougie– Tube
• Indications
• R40: 40 y/o M swollen tongue, difficulty breathing– Hx angioedema – Obtunded, GCS 6, SaO2 80%
• On Arrival– Sitting Up, Nasal O2, rebreather 02
>15lpm– SaO2 75% and GCS 5– LEMON
• Protruding tongue, Swollen face, 0-3-2, stridor
– SHORT• Short Neck
– Consultant suggests Crash Cric• Declare: Can’t Intubate, Can’t Oxygenate
– Skip Checklist• +/- sedation/paralysis • Difficult Airway Call (888)• Crash Cricothyrotomy
– End scenario after tube confirmation

Locate Cric Kit

Cricothyrotomy Assessment• Laryngeal Handshake
• Ultrasound
• SHORT•S: surgery (previous)
•H: haematoma (swelling)
•O: obesity•R: radiation•T: tumor

• Cant intubate, can’t oxygenate (CICO)
• When an experienced clinician thinks it will be safer than intubation from the top.
• Continue to attempt to ventilate from the top with an LMA/BVM
• Age cut-offs?– APLS suggests <12y/o– Some say <6y/o– Others say <3y/o – AKA: it depends
When to Cric Cricothyroidotomy

Preparation
• The “double prep”– Don’t wait until too late– Assess, clean, and mark neck early

Equipment• Simple Cric Kit– Scalpel
– (Bougie on Airway Cart)– 6-0 endotracheal tube (cuffed)
– Dressing Pack• Skin Marker• Antiseptic• KY• 10ml syringe • Blue pad
• Cook surgical-and percutaneous airway kit
10
Cric Technique
• Scalpel-Bougie-Tube • Optimize patient • Oxygenate with BVM/LMA• Locate cricothyroid membrane• Decide to CUT• Vertical cut skin• Horizontal cut membrane • Bougie• 6-0 ETT over bougie until cuff enters• Confirm and ventilate

Airway briefing and checklist• 60y/o with head and face trauma. Who is not protecting his
airway and not oxygenating.
• This is a predicted very difficult airway.
• We will Prepare “double setup” for cric and be ready for an emergent cricothyrotomy
• Declare an 888 airway emergency
• We will use 200mg of ketamine and 100 mg of Rocuronium if needed
•I’ll be team leader •Linda as primary airway operator •I’ll be the backup airway operator •Joyce as airway assistant•James also push the drugs
• The plan is:•A- Direct/bougie/7-0 tube•B- Video/7-0 tube w/ stylet•C- I-LMA #3.5”•D- Scaple-Bougie-6-0 Tube cric
• You can look for 1 minute as we assess and prepare the neck.
• If we can’t intubate and can’t oxygenate will will place an I-LMA, if that doesn’t work, we will perform a scalpel-bougie-tube cricothyrotomy
• Understand your roles
