摘要
A multitude of conditions may cause acute and unexpected upper airway compromise in both children and adults. These include mechanical blockage of the airways either from internal obstructions due to inhaled food or foreign objects, or from external compression. In addition, kinking of the airway in cases of positional asphyxia may compromise aeration. Infections represent another cause of airway narrowing with the potential for occlusion. The case of a 64-year-old man with acute laryngo-epiglottitis is used to demonstrate that death may occur from infections in previously structurally-normal airways. Infections may compromise respiration due to acute airway occlusion from intraluminal material/mucus, mural abscesses or from acutely inflamed and oedematous mucosa with adherent tenacious mucopurulent secretions. External compression from nearby abscesses may also critically narrow air passages.
