The radiographic diagnosis of blunt traumatic aortic laceration (BTAL) remains problematic. We reviewed our experience with chest radiographic signs of BTAL at a single trauma center. ⋯ The experience at our institution suggests that chest radiographs have limited utility in the accurate diagnosis of blunt traumatic aortic laceration. Cross-sectional imaging techniques will likely become the preferred imaging procedures for evaluating patients with suspected BTAL.

Previous studies have reached contradictory conclusions regarding where injured children are best treated. Our hypothesis was that no differences in survival outcome exist among trauma centers caring for pediatric patients. ⋯ The improved unexpected outcome results at Level I centers and centers with Added Qualifications in Pediatrics suggest that a team of qualified professionals working in an institution willing to commit the required resources can sufficiently offer injured children the survival advantage expected of a trauma center.

This study evaluated processes of care and outcome for injured patients at a Level I trauma center who had been either treated as a full trauma team activation (FULL) or managed with a modified trauma team activation (MOD). ⋯ Implementation of the tiered response protocol led to a substantial change in the operational response in the emergency department. Although processes of care were nominally prolonged, adverse consequences were not identified. We concluded from this quality improvement review that implementation of a tiered response protocol was satisfactory and improved efficiency. Further work is required to improve accuracy of the categorization of trauma system patients as either MOD or FULL trauma codes.

Cytokines signal the normal processes of inflammation and repair in all organs, yet the aberrant expression of these peptide mediators is associated with significant organ dysfunction. The accurate measurement of cytokines is therefore critical. In this study, we sought to investigate the alterations in cytokine expression early after trauma in humans using a new competitive binding immunoassay that measures both free and bound cytokine and compare this with standard enzyme-linked immunosorbent assay (ELISA), which measures only free cytokine. ⋯ Cytokine measurements in peripheral blood in trauma patients and normal controls are significantly (10- to 500-fold) higher when using a total cytokine assay that measures both free and bound cytokine. Competitive immunoassays may be the method of choice when measuring endogenous cytokine levels in biologic fluids, and new normal ranges for cytokines must be established for future accurate research in critical care and trauma.

The cost of uncompensated trauma care is a significant barrier to trauma system development. Trauma center designation may burden an institution with an unprofitable mix of underinsured, severely injured patients. Concerns about inadequate reimbursement may motivate interhospital transfers on the basis of insurance status rather than medical necessity, potentially undermining the effectiveness of the system. We set out to explore whether this phenomenon exists in a mature trauma system. ⋯ Insurance status influences the decision to transfer to higher levels of care. These findings suggest that the financial burden of a trauma system may be inequitably distributed. This inequitable distribution may be necessary for trauma system sustainability and calls for the development of disproportionate reimbursement strategies to support regional referral centers.
