- RSI is used to secure the airway quickly with an endotracheal tube and to prevent chance of regurgitation and aspiration
- the basic approach is similar to that in adults
- Note that pretreatment with atropine, while traditionally given prior to intubation in children, is generally not necessary
- follow this link for differences in the paediatric airway
- 4 vital capacity breaths or until ETO2 is concentration >90%
- this may be difficult with an uncooperative child, a cautious dose of fentanyl 0.25mcg/kg IV provides a slightly sedated more compliant child, however caution needs to be taken as airway protection must be maintained, not normally a problem for small children, but older ones may kick up a fuss
- Suction prepared and under pillow
- Apneic oxygenation via nasal prongs
- Induction with thiopentone 3-6mg/kg IV as long as patients haemodynamics will tolerate this dose
- choice of induction age and dose may be modified according to clinical context (e.g. propofol, etomidate)
- Cricoid pressure applied by skilled assistance (optional)
- Suxamethonium 1-2mg/kg IV (2mg/kg for neonates, and 1mg/kg children) OR rocuronium 1.2mg/kg IV
- Once patient fasciculated/ paralysed perform rapid laryngoscopy with placement of a endotracheal tube
- ETT size = age/4 + 4
- traditionally uncuffed until age 8, then cuffed (a ‘one-size smaller’ cuffed tube can be used in children <8 years)
- leak should occur at 20cmH2O if uncuffed
- check endotracheal tube placement by:
- observing tube fogging, chest rising and falling, auscultation of in both axillae and observing end tidal CO2
- if child is >2 years old then endotracheal tube should be at lips by formula age/2 + 12cm
- once endotracheal tube is satisfactory position cricoid pressure can be released
- if a nasogastric tube is in situ leave in place during the procedure as will help decompress stomach if bag-mask ventilation required, remove post procedure if indicated
