Complications
A possible complication of any neck infection that involves the retropharyngeal space. Epiglottitis which extends into this space can spread to the mediastinum, and lead to mediastinitis. This infection is typically characterised by tachycardia and chest pain. These infections are severe and classically associated with a 14% to 42% mortality rate.[32]
Can occur if the infection extends beyond the epiglottis into the deep spaces of the neck. This may be a cellulitis, or could progress into an organised abscess. Imaging (i.e., computed tomography or magnetic resonance imaging) can further delineate the boundaries as well as the severity of the infection.
Is a potential complication with any patient requiring intubation and mechanical ventilation. It is also conceivable that distal spread of the upper airway infection could seed the lower airway with bacteria.
