Prolonged compression of limb muscles and subsequent decompression are important in the development of crush syndrome (CS). We applied a simple rubber tourniquet to rat hind limbs to create a CS model. ⋯ The findings from this study demonstrate the feasibility of a novel small animal model of extremity crush injury. By using this model, the impact of incremental periods of reperfusion on mortality and remote organ dysfunctions can be characterized. Future studies are necessary to better define a threshold for this injury pattern and the impact of other factors underlying this syndrome.

Venous thromboembolism is a major cause of morbidity and mortality after injury. Prophylactic anticoagulation is often delayed as a result of injuries or required procedures. Those patients at highest risk in this early vulnerable window postinjury are not well characterized. We sought to determine those patients at highest risk for an early pulmonary embolism (PE) after injury. ⋯ Early lower extremity/pelvis orthopedic fixation is the single independent predictor of EARLY PE in this patient cohort. Venous thromboembolism/PE prevention strategies should be made a priority in this group of patients, including early preoperative institution of anticoagulation prophylaxis. These results suggest that those with contraindications to early anticoagulation may benefit from insertion of retrievable inferior vena cava filters preoperatively.

To evaluate functional, radiologic, and subjective outcome after volar locking plate osteosynthesis (VLPO) for unstable distal radius fractures (DRF). ⋯ VLPO for the treatment of unstable DRF is a reliable technique with excellent subjective, objective, and radiologic outcome.

Comparative Study
Comparison of trauma mortality and estimated cancer mortality from computed tomography during initial evaluation of intermediate-risk trauma patients.
Computed tomography (CT) is the primary source of nontherapeutic medical radiation exposure. Radiation exposure is associated with an increased risk of cancer mortality. Although the risk of cancer mortality is negligible in comparison with that of trauma mortality in high-risk patients, the balance of risk versus benefit in patients with less severe mechanisms of injury is unknown. ⋯ The risk of mortality from trauma is six times higher than the estimated risk of radiation-induced cancer mortality in intermediate level trauma patients. The mortality due to trauma is greatest in older patients, suggesting lower clinical suspicion is needed to warrant CT studies in this population. Efforts to reduce radiation exposure to trauma patients should focus on young patients with minor injuries.

The early resuscitation occurs in the emergency department (ED) where intensive care unit protocols do not always extend and monitoring capabilities vary. Our hypothesis is that increased ED length of stay (LOS) leads to increased hospital mortality in patients not undergoing immediate surgical intervention. ⋯ In this patient population, a longer ED LOS is associated with an increased hospital mortality even when controlling for physiologic, demographic, and anatomic factors. This highlights the importance of rapid progression of patients through the initial evaluation process to facilitate placement in a location that allows implementation of early goal directed trauma resuscitation.
