1. Paediatric Stridor (airway compromise) Mr. Gerry Siou BSc.(Hons) MD FRCS(ORL-HNS)
Consultant ENT Surgeon
2. Paediatric life support for the non-breathing child SAFE approach
ABC
Airway manoeuvres
Head tilt/chin lift
Neutral (Infant)
‘Sniffing’ (child)
Jaw thrust (care)
Look, listen, feel
5 rescue breaths
3. Securing the airway Oropharyngeal – Guedel
Nasopharyngeal
Endotracheal tube (>1year age)
Internal diameter (mm) – (age/4) + 4
Oral ET length (cm) – (age/2) + 12
Nasal ET length (cm) – (age/2) + 15
Neonates – 2.5-3.5 mm internal diameter
4. Acute Stridor Stridor
Noisy breathing caused by partial obstruction of respiratory tract at or below larynx
Stertor
Noisy breathing caused by partial obstruction of respiratory tract above larynx
5. History of ‘the noise’ Worse asleep
?Pharyngeal
Worse with exertion
?larynx/trachea/brochial
Inspiratory
?supraglottic
Biphasic
?glottic/subglottic ?laryngotracheobronchitis
6. Airway anatomical differences
7. Clinical signs of airway compromise ? ? Resp rate +/- shallow resps
Subcostal recession
Intercostal recession
Suprasternal tug
Stridor (caution)
Cyanosis
Tiring/Agitation/confusion
10. Why is the infant airway more at risk? Poiseuille's equation
Resistance ? 1/r4
Flow ? r4
11. Diagnosis & management
12. Medical ‘First aid’ management Keep calm! (you, the child and everyone else)
Parent and essential personnel only
Anaesthetic team
Nebulised adrenalin
Dexamethasone
Heliox
13. Foreign body airway obstruction Infant
Back blows
Chest thrusts
Child
Back blows
Heimlich
14. Airway assessmentWhat ‘kit’ do I need? Laryngoscopes
Bronchoscopes
Graspers
Sucker
Hopkins Rod
Camera + Stack
(Tracheostomy tray + Tubes)
15. Paediatric laryngoscopes
16. Ventilating bronchoscopes
18. Optical graspers
20. Airway assessment
21. Supraglottic examples
22. Glottic examples
23. Laryngeal cleft grading
24. Subglottic examples
25. Mayer-Cotton Grading of subglottic stenosis
26. Dynamic view
27. Paediatric tracheostomy Old indications?
Infective upper airway
Current indications?
Chronic obstruction/ventilation
28. Surgeon’s perspective
29. Exposure and technique Small skin incision
Remove subcutaneous fat
Vertical tracheotomy
Maturation suture
Stay sutures
30. Maturation suture
31. Tracheostomy tubes Shiley Neo
Shiley Ped
33. EXITEX utero Intrapartum Treatment Pre-natal diagnosis
Congenital laryngeal atresia
Other upper aerodigestive or neck mass causing potential airway problems
34. EXITEX utero Intrapartum Treatment NOT a caesarian section
Maximise uterine tone – prevent post-partum haemorrhage
Minimize trans-placental diffusion of inhalation anaesthetic agents
EXIT procedure
Promote uterine hypotonia – maintain uteroplacental circulation
Preserve uterine volume – prevent uterine abruption
Deep maternal anaesthesia – normal maternal BP
Adequate foetal anaesthesia – no cardiac depression
35. EXITEX utero Intrapartum Treatment Low transverse or midline incision – placental position
Partial delivery of foetus (head, neck, shoulders)
Umbilical cord attached
Direct laryngoscopy + intubation
Tracheostomy
