Accidental trauma is the leading cause of fatal and nonfatal injury among children in the United States. Hemorrhage specifically is the leading cause of preventable death after traumatic injury. Given these facts, and the continuing threat of mass causality events, schools must equip themselves with systematic approaches to disaster preparedness, the management of penetrating trauma, and the prevention of hemorrhagic shock. This chapter presents a case of three children sustaining injuries and discusses the recognition and acute stabilization of life-threatening hemorrhage, as well as the steps schools can take to prepare for emergencies.
