Infants who present with an acute event reported by the caregiver represent a wide range of patients with diverse pathophysiology.
The challenge as physicians is to identify those who are at risk of recurrence or of having a serious underlying disorder.
The term “BRUE” (Brief Resolved Unexplained Event) has replaced the term “ALTE” (Apparent Life-Threatening Event).
ALTE is an old term for events that are characterised by some combination of “apnoea, colour change, change in muscle tone, or choking and gagging and are frightening to the observer”.
This term has been replaced as it described events that ranged from normal physiological events to pathological events and so was not useful in determining diagnosis, treatment or prognosis. In the majority of patients, ALTEs were often benign, but the name implied that the child’s life was at risk. This reinforced parental anxiety and potentially led to unnecessary investigations. |
