The purpose of this study was to assess the ability of the International Classification of Diseases-based Injury Severity Score (ICISS) to detect preventable deaths, and to compare the performance of trauma care facilities. ⋯ The degree of agreement in the preventability of trauma death derived from the ICISS with a professional judgment on preventability was similar to that derived from the Trauma and Injury Severity Score. The W-scores of EMCs correlated well with their preventable death rates, with marginal statistical significance. This study has demonstrated that the ICISS is useful in detecting preventable deaths and in comparing the performance of trauma care facilities.

Duodenal injury secondary to blunt trauma continues to pose a diagnostic challenge. The purpose of this study is to evaluate the cause, radiologic findings, and management of duodenal injuries from a Level I pediatric trauma center. ⋯ CT scanning remains a valuable tool in the diagnosis of blunt duodenal injuries in children. Although extravasation of oral contrast was not beneficial, the presence of extraluminal air was highly suggestive of perforation. The vast majority of hematomas were successfully managed nonoperatively, and duodenorrhaphy was safe and effective therapy for perforations.

The Glasgow Coma Scale (GCS) has served as an assessment tool in head trauma and as a measure of physiologic derangement in outcome models (e.g., TRISS and Acute Physiology and Chronic Health Evaluation), but it has not been rigorously examined as a predictor of outcome. ⋯ Because the motor component of the GCS contains virtually all the information of the GCS itself, can be measured in intubated patients, and is much better behaved statistically than the GCS, we believe that the motor component of the GCS should replace the GCS in outcome prediction models. Because the m component is nonlinear in the log odds of survival, however, it should be mathematically transformed before its inclusion in broader outcome prediction models.

Blunt chest trauma is an important clinical problem leading to injury of the heart and lungs that may be fatal. Experimental models in large animals have been developed previously. This study was aimed at developing a small-animal (rat) model for the purpose of evaluating blunt chest trauma. ⋯ This study has established a useful model for the study of blunt chest trauma in a small animal (rat). Blunt chest trauma is associated with cardiac arrhythmia, which may be fatal. Injury to the heart may not correlate with serious cardiac arrhythmia resulting in death, lending credence to the concept of cardiac concussion or commotio cordis. Lung contusion is always more obvious than morphologic injury to the heart.
