The paediatric airway: anatomy, physiology and management
Also known as Paediatric airway · Pediatric airway management · Infant airway · Neonatal airway · Paediatric difficult airway
The paediatric airway differs from the adult airway in anatomy, physiology and equipment, and these differences drive every aspect of safe management — from positioning and preoxygenation to the difficult-airway algorithm and emergency front-of-neck access. Children desaturate far faster than adults, so airway crises tolerate no delay.

Red flags
- A child with stridor at rest, tracheal tug, intercostal recession or accessory-muscle use is at high risk of obstruction on induction — keep them upright and breathing spontaneously until the airway is secured.
- A febrile, toxic, drooling child sitting forward in tripodi is epiglottitis until proven otherwise — do not lie them flat or instrument the airway awake; call for senior anaesthetic and ENT help.
- Saturations fall into the seventies within under a minute of apnoea in a small child — preoxygenation is harder and the safe apnoeic window is far shorter than in adults.
- A barking cough and inspiratory stridor after a recent upper respiratory infection signals croup; a recent URTI multiplies the risk of perioperative airway adverse events.
- Repeated laryngoscopy attempts cause oedema in the narrow paediatric subglottis; each attempt narrows the airway further — limit attempts and escalate early.
- In the neonate or infant the cricothyroid membrane is tiny and a needle cricothyroidotomy is preferred over the open scalpel technique used in adults.
Meet the patient
A three-year-old is brought to theatre at midnight with a barking cough, inspiratory stridor at rest, and intercostal recession that started after a viral upper respiratory infection. She sits upright on her mother's lap, refusing to lie flat, and the saturation monitor reads 91 percent in room air. The instinct to lay her down, preoxygenate, and induce is wrong — it will obstruct the airway she is holding open by effort, and she will desaturate in under a minute.[1]
The two questions that decide the next hour are the two every paediatric airway stem turns on: will this child tolerate apnoea? (the physiological reserve answers in seconds) and can I secure the airway before the reserve runs out? (the equipment, the technique, and the plan answer in minutes).[1]
