Evaluation of Apparent Life-Threatening Events in Infants

Abstract

A comprehensive, detailed history and physical examination with pulse oximetry and nondilated funduscopy (to look for traumatic retinal hemorrhage) helps to determine the underlying etiology of an apparent life-threatening event (ALTE) in 70 percent of infants. (Strength of Recommendation [SOR]: C, based on case series). Initial diagnostic evaluation should include 12-lead electrocardiography (ECG); blood gas analysis; chest radiography; complete blood count (CBC); pertussis and respiratory syncytial virus cultures, if respiratory symptoms are present; serum electrolytes; and urinalysis. (SOR: C, expert opinion and case series).
