"Perimortem" total body CT-scan examination in severely injured children: an informative insight into the causes of death.

Abstract

To report routine practice of "perimortem" CT-scan imaging to determine the causes of death in children dying from severe accidental injuries within the first hours following hospital admission. Trauma center of a University Pediatric Hospital. A retrospective study was conducted in children (0 to 15years old) referred for severe trauma (GCS ≤ 8) to a regional pediatric trauma center, presenting with at least spontaneous cardiac rhythm and dying within the first 12h after admission. "Perimortem" CT-scan consisted in high-resolution, contrast-enhanced, full-body CT-scan imaging, performed whatever child's clinical status. Lethal and associated lesions found were analyzed and classified according to validated scales. The comparison between clinical and radiological examinations and CT-scan findings evaluated the accuracy of clinical examination to predict lethal lesions. CT-scan performed in 73 children detected 132 potentially lethal lesions, at least 2 lesions in 63%, and 1 in 37% of the cases. More frequent lethal lesions were brain (43%), and chest injuries (33%), followed by abdominal (12%), and cervical spine injuries (12%). Clinical and minimal radiological examinations were poorly predictive for identifying abdominal/chest lesions. Clinical and imaging data provided to the medical examiner were considered sufficient to identify the cause of death, and to deliver early burial certificates in 70 children. Only three legal autopsies were commanded. Perimortem CT imaging could provide an insight into the causes of death in traumatized children. Performed on an emergency basis near death, it eliminates the difficulties encountered in forensic radiology. It could be a possible alternative to full-scale forensic examination, at least regarding elucidation of the potential, or highly probable causes of death.
