Venous thromboembolism (VTE) is a major source of morbidity in critically ill trauma patients. Although the incidence and risk factors for VTE after trauma in adults have been well described, similar data regarding pediatric patients are lacking. ⋯ Older children with high Injury Severity Scores, major vascular injury, craniotomy, or venous catheters are at risk for VTE. These data may help guide strategies geared toward screening and prophylaxis in injured children.

Our knowledge about the bidirectional interactions between brain and whole organism after trauma is still limited. It was the purpose of this prospective clinical study to determine the influence of severe head trauma (SHT) as well as trauma in different anatomic injury regions on posttraumatic inflammatory mediator levels from patients with multiple injuries. ⋯ Traumatic injuries cause the liberation of various mediators, without any specific association between anatomic injury pattern and the pattern of mediator release.

Surgical reconstruction is indicated for posterior cruciate ligament (PCL) reconstruction for a grade III or IV injury, combined ligament or meniscus injuries, and chronic symptomatic posterior instability. Considerable controversy continues over the choice of graft tissues. Hamstring tendon has been popular in recent years. The purpose of this study is to prospectively assess the outcomes of PCL reconstruction using quadruple hamstring tendon autograft with a double-fixation technique at minimal 2-year follow-up. ⋯ Arthroscopic PCL reconstruction with quadruple hamstring tendon autograft appears to produce acceptable results at a minimal 2-year follow-up. The four-stranded hamstring tendon graft is adequate in graft size and associated with minimal harvesting morbidity. The double-fixation method for the graft could provide a rigid fixation. We believe that this technique could afford good ligament function after reconstruction and could be a reasonably acceptable choice for PCL injury.

Comparative Study
Relative importance of designation and accreditation of trauma centers during evolution of a regional trauma system.
Improved survival after injury has been demonstrated with trauma system implementation and designation of trauma centers. Local designating health authorities or national verification (United States) or accreditation (Canada) programs audit trauma center performance. The relative importance of designation versus accreditation with respect to improved outcomes is not clear. The purpose of this study was to measure outcomes within a single regional trauma system after designation of trauma centers and to compare outcomes in the one accredited center to the nonaccredited centers. ⋯ Differences between hospitals were apparent from the outset of the trauma system. However, designation as a trauma center does not appear to necessarily improve survival in large regional medical centers. Development of a trauma program and commitment to meeting national guidelines through the accreditation process does appear to be associated with improved outcome after injury.

Motor vehicle collision-related blunt thoracic aorta injury (BAI) is rare and highly lethal. Vascular disease as related to advancing age potentially subjects older adults to increased risk of BAI; the mechanisms associated with such injuries may be different as compared with younger adults. The goal of the present study is to test this hypothesis using population-based data. ⋯ Older adults have the highest rate of motor vehicle collision-related BAI, and their injuries tend to occur in less severe collisions. A high level of suspicion for BAI among older adults should not be reserved for high-energy collisions only.
