PEDIATRIC AIRWAY MANAGEMENT
Introduction
Paediatric airway management is one of the most important and challenging aspects of paediatric anaesthesia. Children are not small adults; they possess unique anatomical and physiological characteristics that predispose them to airway obstruction, difficult ventilation, rapid desaturation, and airway-related complications.
The primary goals of paediatric airway management are:
• Maintain airway patency
• Ensure adequate oxygenation
• Ensure effective ventilation
• Protect against aspiration
• Secure the airway safely
• Anticipate and manage difficult airway situations
• Plan for safe extubation
Fundamental Principle: Oxygenation is more important than intubation.
Airway Assessment
History
Important questions include:
• Previous difficult intubation
• Previous tracheostomy
• Obstructive sleep apnoea
• Noisy breathing
• Stridor
• Previous airway surgery
• Congenital syndromes
Clinical Pearl: A previous difficult airway remains the strongest predictor of a future difficult airway.
Physical Examination
Assess:
• Facial symmetry
• Mandibular size
• Mouth opening
• Tongue size
• Neck mobility
• Airway masses
• Mallampati classification
• COPUR index (COPUR score >10 suggests increased likelihood of difficult intubation)

Recent advances and guideline updates in paediatric airway management (2024–2025)
This section summarizes major recommendations from:
- ESAIC–BJA Neonatal and Infant Airway Guidelines (2024)
- DAS Pediatric Difficult Airway Guidelines
- Recent Pediatric Airway Safety Reviews (2024–2025)
1. Video Laryngoscopy is Becoming First-Line
Traditionally, video laryngoscopy (VL) was considered a rescue device.
Current evidence supports:
• Earlier use of VL
• Higher first-pass success rates
• Better glottic visualization
• Reduced airway trauma
• Fewer esophageal intubations
Video laryngoscopy should be considered early in:
• Neonates and infants
• Anticipated difficult airway
• Failed direct laryngoscopy
• Teaching environments
Key Message: Video laryngoscopy is increasingly a first-line rather than a rescue device.
2. Oxygenation Takes Priority Over Intubation
Modern difficult airway management emphasizes: Maintain oxygenation at all times.
Repeated attempts at intubation should never compromise oxygenation.
The priority sequence is:
- Oxygenation
- Ventilation
- Intubation
3. Per-Oxygenation
One of the most important recent developments.
Definition: Continuous oxygen administration throughout airway management.
Methods:
• Nasal cannula oxygen
• High-flow nasal oxygen (HFNO)
• Oxygen insufflation during laryngoscopy
Advantages:
• Increased safe apnoea time
• Delayed desaturation
• Reduced hypoxemia during difficult airway management
4. First-Pass Success is the New Airway Quality Indicator
Multiple laryngoscopy attempts are associated with:
• Hypoxemia
• Bradycardia
• Airway trauma
• Cardiac arrest
Current goal: Maximize first-pass success.
Strategies include:
• Experienced operator
• Video laryngoscopy
• Proper positioning
• Adequate preparation
5. Limit Intubation Attempts
Both DAS and recent international guidelines strongly discourage repeated laryngoscopy.
Recommendations:
• Maximum two attempts per operator
• Escalate early to alternative devices
• Call for help promptly
Repeated attempts increase:
• Airway oedema
• Bleeding
• Hypoxemia
• Difficulty of subsequent attempts
6. Early Use of Supraglottic Airway Devices (DAS Recommendation)
A major change in difficult airway management philosophy.
Historically:
• SGA insertion was delayed
Current recommendation:
• Early insertion of second-generation SGAs
Benefits:
• Rapid restoration of oxygenation
• Reduced hypoxemia
• Provides a conduit for fibreoptic intubation
• Allows time for reassessment
Preferred Devices:
• i-gel
• ProSeal LMA
• Supreme LMA
DAS Principle: If intubation fails, oxygenate first with an SGA rather than repeatedly attempting laryngoscopy.
7. Human Factors Are Major Contributors to Airway Failure
Modern airway research has shown that many airway catastrophes result from:
• Communication failures
• Poor planning
• Fixation errors
• Delayed help-seeking
• Teamwork failures
Recommended Strategies:
• Pre-induction briefing
• Closed-loop communication
• Defined team roles
• Cognitive aids
8. Airway Management is a Team-Based Process
Modern airway practice emphasizes:
• Shared situational awareness
• Clearly assigned roles
• Early senior involvement
• Team communication
Clinical Pearl: Difficult airway management is rarely a single-operator activity.
9. Cognitive Aids Improve Safety
Recommended tools include:
• Airway checklists
• Difficult airway algorithms
• Emergency action cards
• Crisis manuals
Benefits:
• Reduced omission errors
• Improved decision making
• Better team coordination
10. Structured Airway Planning
Every paediatric airway should include:
Plan A: Primary airway strategy
Plan B: Alternative intubation strategy
Plan C: Rescue oxygenation strategy
Plan D: Emergency front-of-neck access
Key Principle: Never proceed to induction without a backup plan.
11. Difficult Airway Prediction Remains Imperfect
No bedside assessment reliably predicts every difficult airway.
Limitations exist for:
• Mallampati score
• Thyromental distance
• Airway ultrasound
• AI-based prediction systems
Strongest Predictor: Previous documented difficult airway.
12. Preservation of Spontaneous Ventilation
Particularly important in:
• Pierre Robin sequence
• Severe airway obstruction
• Mediastinal masses
• Craniofacial abnormalities
Advantages:
• Maintains airway patency
• Preserves oxygenation
• Provides safety margin
13. Neuromuscular Blockade Improves Intubation Conditions
Current evidence suggests:
• Better laryngoscopic view
• Improved first-pass success
• Reduced airway trauma
Exception:
• Anticipated difficult airway where spontaneous ventilation is required
14. Combined Airway Techniques
Increasing use of:
- Video Laryngoscope + Fibreoptic Bronchoscope
- SGA-Assisted Fibreoptic Intubation
- Four-Hand Intubation Technique
Particularly useful in:
• Syndromic difficult airways
• Severe craniofacial abnormalities
15. Airway Ultrasound as a Point-of-Care Tool
Emerging applications include:
• ETT size prediction
• Confirmation of tracheal placement
• Identification of cricothyroid membrane
• Assessment of airway anatomy
Currently considered an adjunct rather than a replacement for standard assessment.
16. Extubation is an Airway Procedure
A major modern concept.
Extubation deserves the same planning as intubation.
High-risk extubations require:
• Airway strategy
• Rescue plan
• Immediate availability of reintubation equipment
17. Difficult Airway Documentation and Registries
Increasing emphasis on:
• Difficult airway alerts
• Electronic airway records
• Airway registries
Purpose:
• Improve future airway safety
• Reduce repeated airway complications
18. Early Recognition of Airway Failure
A major DAS recommendation.
Do not persist with a failing technique.
Early recognition and escalation improve outcomes.
19. Earlier Declaration of CICO (DAS Recommendation)
One of DAS’s strongest messages.
Current Philosophy: Recognize failure early.
Avoid:
• Multiple failed attempts
• Delayed decision-making
• Progressive hypoxemia
Principle: Declare CICO early and act decisively.
20. Emergency Front-of-Neck Access (eFONA)
Although rare:Remains the final life-saving intervention
Current recommendations:
• Familiarity with institutional technique
• Availability of equipment
• Team rehearsal
Key Message: Do not delay eFONA once CICO is established.
21. Simulation-Based Airway Training
Increasingly recommended by all major airway societies.
Training should include:
• Difficult airway scenarios
• Failed intubation drills
• SGA rescue techniques
• CICO management
• eFONA practice
Benefits:
• Improved technical performance
• Better teamwork
• Faster crisis recognition
22. Shift from Device-Centred to System-Centred Airway Management
Perhaps the most important conceptual change.
Older airway management focused primarily on:
• Laryngoscopy
• Intubation devices
Modern paediatric airway management focuses on:
• Oxygenation
• Teamwork
• Human factors
• Communication
• Cognitive aids
• Rescue pathways
• Patient safety systems
Modern Philosophy: Successful airway management is not defined by placing a tube; it is defined by maintaining oxygenation safely throughout the airway journey.
