Difficulties in pediatric airway management are common and continue to result in significant morbidity and mortality. This review reports on current concepts in approaching a child with a difficult airway. Routine airway management in healthy children with normal airways is simple in experienced hands. Mask ventilation (oxygenation) is always possible and tracheal intubation normally simple. However, transient hypoxia is common in these children usually due to unexpected anatomical and functional airway problems or failure to ventilate during rapid sequence induction. Anatomical airway problems (upper airway collapse and adenoid hypertrophy) and functional airway problems (laryngospasm, bronchospasm, insufficient depth of anesthesia and muscle rigidity, gastric hyperinflation, and alveolar collapse) require urgent recognition and treatment algorithms due to insufficient oxygen reserves. Early muscle paralysis and epinephrine administration aids resolution of these functional airway obstructions. Children with an 'impaired' normal (foreign body, allergy, and inflammation) or an expected difficult (scars, tumors, and congenital) airway require careful planning and expertise. Training in the recognition and management of these different situations as well as a suitably equipped anesthesia workstation and trained personnel are essential. The healthy child with an unexpected airway problem requires clear strategies. The 'impaired' normal pediatric airway may be handled by anesthetists experienced with children, whereas the expected difficult pediatric airway requires dedicated pediatric anesthesia specialist care and should only be managed in specialized centers.

Perioperative airway problems frequently result in significant morbidity and mortality in children. Therefore, proficiency in airway management is one of the most important key elements in the safe conduct of paediatric anaesthesia. This review includes important anatomical and physiological aspects of the paediatric airway, challenges encountered, and their management with commonly available resources. The importance of early recognition and treatment of anatomical or functional airway obstruction using locally adapted algorithms is highlighted. Children deemed at risk of aspiration require a controlled rapid sequence induction with sufficiently deep anaesthesia, confirmed complete muscle paralysis and intermittent ventilation prior to tracheal intubation. The benefits of a supraglottic airway device and a cuffed tracheal tube in paediatric airway management are discussed. The primary goal of mastering the paediatric airway is to ensure oxygenation and ventilation. This requires intricate knowledge, regular practice and experience.
