Commercially Available Pediatric Cricothyrotomy Kits
There are extremely limited commercially available pediatric-specific cricothyrotomy kits, and critically, catheter-based approaches are NOT recommended in children under 8 years old due to high failure and complication rates. 1
Critical Age-Based Distinction
The most important clinical reality is that pediatric cricothyrotomy differs fundamentally from adult approaches, and most "pediatric" kits are actually only appropriate for older children (≥8 years):
Children Under 8 Years Old
- Catheter-based cricothyrotomy is contraindicated 1
- The cricothyroid membrane is extremely small and difficult to identify
- High risk of complete airway obstruction, barotrauma, and surgical emphysema
- Surgical cricothyrotomy with scalpel-bougie-tube technique is preferred if emergency front-of-neck access is absolutely necessary 1
Children 8 Years and Older
- May tolerate adult-sized equipment with appropriate size adjustments
- 4mm cannula with low-pressure ventilation may be successful in spontaneously breathing patients 2
Available Commercial Devices
Quicktrach Baby™
- The only device specifically evaluated for infant use 3
- Consists of plastic cannula over metal needle for direct tracheal placement
- Animal model data shows:
- Successful placement in all attempts
- Mean placement time: 31 seconds
- Complications: cricoid cartilage fracture (20%), posterior wall damage (10%)
- Sufficient ventilation achieved in all cases 3
- Important caveat: Despite successful animal testing, this remains a catheter-based approach with the inherent limitations discussed above
Adult Kits Potentially Adaptable for Older Children
The following are designed for adults but have been evaluated in veterinary/cadaver models 4:
- Portex® PCK (Percutaneous Cricothyrotomy Kit)
- Melker Universal Cricothyrotomy Kit (Seldinger technique)
- H&H® Emergency Cricothyrotomy Kit
These require significant technique modifications for pediatric use and are NOT appropriate for infants or young children 5
The Fundamental Problem
Most commercially available devices are designed for adults and are impractical or dangerous in neonates and infants 5. The unique anatomy includes:
- Extremely small cricothyroid membrane
- Technical difficulty locating anatomical structures
- High complication risk with percutaneous devices
Recommended Equipment for Pediatric Emergency Airway
Rather than relying on commercial kits, guidelines recommend having available 2:
For Needle Cricothyrotomy (if attempted despite limitations):
- 4mm cannula
- 20ml syringe for air aspiration confirmation
- Low-pressure ventilation system
For Surgical Cricothyrotomy (preferred method):
- Short, rounded scalpel (no. 20 or Minitrach scalpel)
- Small cuffed tracheal or tracheostomy tube (6-7mm for older children)
- Tracheal hook for caudal traction on cricoid
- Bougie for tube guidance
Critical Clinical Algorithm
When facing cannot-intubate-cannot-oxygenate (CICO) in children:
Exhaust all non-invasive options first 1, 6
- Supraglottic airways
- Two-person mask ventilation
- Videolaryngoscopy
If SpO₂ < 80% and/or decreasing heart rate 1:
- Call for experienced ENT surgeon
- Consider emergency tracheostomy by surgeon as first-line
- Rigid bronchoscopy with jet ventilation if available
If cricothyrotomy unavoidable:
- Age < 8 years: Surgical technique only (scalpel-bougie-tube)
- Age ≥ 8 years: Either surgical or carefully selected catheter technique
- Convert to definitive airway as soon as possible 2
Common Pitfalls
- Assuming pediatric kits exist for all ages - they don't
- Using adult catheter-based kits in young children - contraindicated
- Attempting jet ventilation in infants - high risk of barotrauma and complete obstruction
- Delaying surgical consultation - ENT/surgery should be called immediately in pediatric CICO
The harsh reality: there is no ideal commercial pediatric cricothyrotomy kit for emergency use in young children, which is why prevention of CICO through meticulous airway assessment and planning is paramount 1, 5.
