Pediatric Stridor

“…The cuffed tracheal tubes effect on stridor risk, (adjusting for confounders), was non-significant: OR = 2,2; Conf. Interval 95% [0, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]; p = 0,5. Conclusions: The use of cuffed endotracheal tubes did not increase the risk of post-extubation stridor in children.…”

“…These effects are so significant that 1 mm of swelling in a neonatal subglottis, that is 5 mm in diameter, results in a 60% reduction in flow. 3 When the rapid, turbulent airflow creates a resonant vibration among the tissues of the airway, a sound results, which is known as stridor.…”

Infections of the pediatric airway result in partial obstruction of the airway and often require intervention to maintain the airway. Most airway infections are treated medically, but respiratory support or invasive airway protection may be required if the patient does not respond adequately to initial interventions. We review three major types of central airway infections, focusing on illustrative diagnostic and treatment dilemmas.

“…intrinsic or extrinsic, are less common. Classically, obstruction of the upper airway produces stridor, and the type of stridor is defined by the level of obstruction (9). Inspiratory stridor is caused by narrowing of the epiglottic, glottic, and subglottic regions (9).…”

“…Classically, obstruction of the upper airway produces stridor, and the type of stridor is defined by the level of obstruction (9). Inspiratory stridor is caused by narrowing of the epiglottic, glottic, and subglottic regions (9). Biphasic stridor may be caused by narrowing of the glottic or subglottic regions, and expiratory stridor is caused by narrowing of the trachea (9).…”

Acute airway obstruction is much more common in infants and children than in adults because of their unique anatomic and physiologic features. Even in young patients with partial airway occlusion, symptoms can be severe and potentially life-threatening. Factors that predispose children to airway compromise include the orientation of their larynx, the narrow caliber of their trachea, and their weak intercostal muscles. Because the clinical manifestations of acute airway obstruction are often nonspecific, clinicians often rely on the findings at imaging to establish a diagnosis. Several key anatomic features of the pediatric airway make it particularly susceptible to respiratory distress, and the imaging recommendations for children suspected of having acute airway obstruction are presented. Although cross-sectional imaging may be helpful, the diagnosis can often be established by using radiographs alone. Radiographs of the chest and upper airway should be routinely acquired; however, for the child who is in severe distress, a single lateral radiographic view may be all that is necessary. The purpose of this article is to provide an imaging approach to acquired causes of acute airway obstruction in children, including (a) abnormalities affecting the upper portion of the airway, such as croup, acute epiglottitis, retropharyngeal infection, and foreign bodies, and (b) abnormalities affecting the lower portion of the airway, such as asthma, bronchiolitis, and foreign bodies. It is essential that the radiologist recognize key imaging findings and understand the pathophysiologic features of acute airway obstruction because in most cases, when the cause is identified, the condition responds well to prompt management.
