Cricothyrotomy

Cricothyrotomy is the endpoint of the can’t intubate, can’t ventilate airway algorithm and one of emergency medicine’s classic HALO procedures. Success depends less on bravado than on anatomy, early decision-making, and a simple reproducible setup when seconds matter.

ED Cricothyrotomy Pearls and Pitfalls

• HALO airway reality: Cricothyrotomy is a high-acuity, low-occurrence rescue airway, and the hardest step is often deciding to cut before repeated failed attempts turn a salvageable airway into a crash.
• Shared airway algorithm: A verbalized can’t-intubate, can’t-ventilate plan lowers room anxiety and clarifies when to move from tube, bougie, bronchoscope, and supraglottic rescue to a surgical airway. We walk through the decision pivot in the episode.
• Landmarking before induction: Routine neck palpation and pre-marking the cricothyroid membrane before intubation pays off when anatomy becomes obscured by obesity, blood, edema, or time pressure.
• Vertical incision strategy: A generous midline vertical skin incision, about 4 cm, creates working space and avoids the anterior jugular veins better than a small horizontal skin cut.
• Tube size sweet spot: A 6.0 to 6.5 endotracheal tube offers a practical balance between passing the opening and providing adequate ventilation, and it is usually easier to find than a trach tube.
• Complication priorities: Bleeding, false lumen, esophageal injury, pneumothorax, and vocal fold trauma all occur, but the immediate priority remains securing the airway; several troubleshooting moves are worth hearing in the chapter.

Troubleshooting and Pediatric Rescue Airway

• Bronchoscope rescue role: Flexible bronchoscopy can sometimes avert a surgical airway and can also confirm tube position or help recover from a false passage when the anatomy is unclear.
• False lumen recovery: When the tube tracks into soft tissue, scope-assisted withdrawal and re-advancement can salvage the airway without starting from zero. We lay out the bedside sequence in the podcast.
• Pediatric age uncertainty: The lower age limit for surgical cricothyrotomy is not fixed in the literature, with recommendations varying widely, so younger children are usually managed with needle cricothyrotomy first.
• Needle cric bridge: Needle cricothyrotomy is a temporizing maneuver in children, buying roughly 40 to 60 minutes before hypercapnia becomes the limiting problem.
• High pediatric landmark: In small children, the target is often higher than expected, near the hyoid region, so finding the midline airway matters more than chasing an adult-style cricothyroid membrane.
