Upper Airway Obstruction in a Child
This is an airway emergency with upper airway obstruction in a paediatric patient.
Call for help!
- assess whether intubation needs to take place now
- if patient is still breathing – keep them breathing and transfer to OT for inhalational induction with most experienced with the paediatric airway
- if patient is not breathing – attempt bag-mask ventilation with 100% O2 and attempt intubation now
- paediatric anaesthetist
- ENT surgeon
- notify theatre
- O2 (can hold mask away from face if distressing)
- keep child calm (allow to stay in parents arms, EMLA for IV access)
- adrenaline nebuliser (5mg)
- dexamethasone 0.6mg/kg IV
- oxygen/helium mixture if tolerates
- ETCO2 ready
- work of breathing
Equipment and Drugs
- Weight = age + 4 x 2 = 12kg
- Selection of laryngoscopes – size 1 – 3, (straight and curves)
- Selection of guedels
- Selection of ETT – age/4 +4 = 4.5 but will need smaller tube given upper airway obstruction (3.5, 4.0, 4.5, oral and nasal, uncuffed)
- LMA – #1.5 and #2
- Trans-tracheal airways
- Volatile anaesthetic agents – sevoflurane
- IV induction agents – propofol 3-4mg/kg, thiopentone 3mg/kg
- Muscle relaxants – suxamethonium 1-2mg/kg IV
- Resuscitation drugs – atropine 25mcg/kg, adrenaline 0.1mL/kg of 1:10,000, metaraminol increments
- Fluids – N/S 10-20mL/kg boluses
- Inhalational induction in OT with scrubbed ENT surgeon ready to secure a trans-tracheal airway, OR RSI if child in extremis
- Keep child spontaneously breathing as long as possible
- Bag-mask +/- Guedel or nasal ETT
- LMA insertion
