Epistaxis in children

Overview & Definition

A mother rings the after-hours line about her four-year-old, frightened because blood is dripping from one nostril after he rubbed it in a warm room. An hour later, in the emergency department, a seven-year-old is brought in tilted backward in a chair, a towel soaked with blood and now vomiting. Both have epistaxis, but the first is the benign anterior majority that first aid settles in minutes, and the second shows how a wrong technique turns a small bleed into a mess. The fellowship skill is to recognise that most childhood epistaxis is benign and anterior, and to teach and apply correct first aid without delay. [1]

Epistaxis is bleeding from the rich vascular network of the nasal mucosa. The nose is one of the most vascular structures in the child, and its vessels lie under a thin mucosa that dries, cracks and bleeds with the least provocation. The defining anatomy is the division into anterior and posterior bleeds: anterior bleeds, overwhelmingly from Little's area (Kiesselbach's plexus) on the anteroinferior nasal septum, account for over 90 percent of childhood epistaxis and are usually mild and self-limiting; posterior bleeds, typically from the sphenopalatine artery, are rarer in children but more profuse, harder to control, and more likely to need packing or specialist care. [1] [3]

What makes the topic examinable is the gap between how common and how benign it usually is, and the few features that signal danger. Most childhood epistaxis is primary (idiopathic), driven by nose picking and dry air, and resolves with simple measures. The minority that is recurrent, posterior, bilateral, profuse or accompanied by systemic signs forces a different response — a bleeding-disorder work-up, a search for a tumour such as juvenile nasopharyngeal angiofibroma, or escalation to cautery and packing. Reading that distinction, and teaching correct first aid, is the core of the topic. [2]
