Accuracy of the abdominal examination for identifying children with blunt intra-abdominal injuries.

Objective: To determine the accuracy of complaints of abdominal pain and findings of abdominal tenderness for identifying children with intra-abdominal injury (IAI) stratified by Glasgow Coma Scale (GCS) score.

Study Design: This was a prospective, multicenter observational study of children with blunt torso trauma and a GCS score ≥13. We calculated the sensitivity of abdominal findings for IAI with 95% CI stratified by GCS score.

Sensitivity of plain pelvis radiography in children with blunt torso trauma.

Study Objective: Plain anteroposterior pelvic radiographs are commonly used to screen children for pelvic fractures or dislocations after blunt torso trauma. The test sensitivity and utility, however, are unclear. We assessed the sensitivity of anteroposterior pelvic radiographs for identifying children with pelvic fractures or dislocations after blunt torso trauma.

Occult pneumothoraces in children with blunt torso trauma.

Objectives: Plain chest x-ray (CXR) is often the initial screening test to identify pneumothoraces in trauma patients. Computed tomography (CT) scans can identify pneumothoraces not seen on CXR ("occult pneumothoraces"), but the clinical importance of these radiographically occult pneumothoraces in children is not well understood. The objectives of this study were to determine the proportion of occult pneumothoraces in injured children and the rate of treatment with tube thoracostomy among these children.

Identifying children at very low risk of clinically important blunt abdominal injuries.

Study Objective: We derive a prediction rule to identify children at very low risk for intra-abdominal injuries undergoing acute intervention and for whom computed tomography (CT) could be obviated.

Methods: We prospectively enrolled children with blunt torso trauma in 20 emergency departments. We used binary recursive partitioning to create a prediction rule to identify children at very low risk of intra-abdominal injuries undergoing acute intervention (therapeutic laparotomy, angiographic embolization, blood transfusion for abdominal hemorrhage, or intravenous fluid for ≥2 nights for pancreatic/gastrointestinal injuries).
