Neonates, infants, and children present a range of unique airway challenges. For example, neonates have a relatively large tongue, a shorter mandible, and a narrower subglottic airway, all of which make mask ventilation and intubation more difficult. The prominence of the occiput in neonates can cause excessive flexion of the neck which causes airway obstruction when they are supine, which necessitates careful positioning to maintain a patent airway. Furthermore, the soft, less calcified cartilage in pediatric patients increases the risk of airway collapse, particularly during anesthesia.
Pediatric patients also have a higher laryngeal position and a narrower airway compared to adults, requiring modifications in airway management techniques. While adult airways are generally cylindrical, pediatric airways are funnel-shaped, with the narrowest point often at the cricoid ring. This makes the selection of appropriately sized endotracheal tubes critical to avoid trauma and ensure a proper fit. Additionally, pediatric patients are obligate nasal breathers until around five months of age, and enlarged adenoids or tonsils can complicate airway management. Given their higher oxygen consumption and lower functional residual capacity, pediatric patients can desaturate more quickly than adults, making rapid and efficient airway interventions essential.
