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.

Comparative Study
Effect of a voluntary trauma system on preventable death and inappropriate care in a rural state.
This study compares the preventable death rate and the nature and degree of inappropriate care in a rural state before and after implementation of a voluntary trauma system. ⋯ Implementation of a voluntary trauma system has positive effects on PDR and inappropriate care. The degree and nature of inappropriate care remain a concern. Mandated and funded system policies may further influence care positively.

Blunt thoracic aortic injury (BAI) is a rare and highly lethal injury. We sought to identify occupant and collision characteristics associated with motor vehicle collision (MVC)-related BAI. ⋯ The risk factors for BAI identified in this study support generally accepted etiologic mechanisms for this injury.

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.
