Bleeding from intra-abdominal injuries is a leading cause of traumatic deaths in children. Abdominal CT is the reference standard test for diagnosing intra-abdominal injuries. Compelling reasons exist, however, to both aggressively evaluate injured children for intra-abdominal injuries with CT and to limit abdominal CT evaluation to solely those at non-negligible risk. The focused assessment sonography for trauma (FAST) examination can help focus patient evaluation in just this manner by potentially safely decreasing abdominal CT use in low risk children. This research study is a multicenter, randomized, controlled trial to determine whether use of the FAST examination, a bedside abdominal ultrasound, impacts care in 3,194 hemodynamically stable children with blunt abdominal trauma. The overall objectives of this proposal are 1) to determine the efficacy of using the FAST examination during the initial evaluation of children with blunt abdominal trauma, and 2) to identify factors associated with abdominal CT use in children considered very low risk for IAI after a negative FAST examination. The long-term objective of the research is to determine appropriate evaluation strategies to optimize the care of injured children, leading to improved quality of care and a reduction in morbidity and mortality.

Rate of abdominal CT scanning
Timeframe: For the duration of the subject's Emergency Department stay and initial hospitalization (up to 24 hours)
Rate of delayed or missed or delayed intra-abdominal injuries
Timeframe: In hospitalized participants, IAI collection will be captured from the time of assignment until discharge (up to 30 days). For participants discharged from the ED IAI collection will be captured from the time of assignment until 7 days after ED discharge
Identifying variables associated with obtaining abdominal CT scans in very low risk patients with normal FAST examinations
Timeframe: The binary indicator assessment of yes/no will occur upon discharge from the Emergency Department or admission to the hospital, an average of 6.5 hours
