As trauma care evolves, there has been increased reliance on imaging. The purpose of this study was to examine changes in trauma imaging and radiation exposure over time. Our hypothesis was that there has been an increased usage of imaging in the management of trauma patients without measurable improvements in outcomes. ⋯ From 2002 to 2007, there was a significant increase in the use of CT and plain radiographs in the management of trauma patients, leading to significantly higher radiation exposure with no demonstrable improvements in the diagnosis of missed injuries, mortality, or length of stay.

The amount of free fluid that can normally be present in a pregnant patient is unknown. Evaluation of pelvic free fluid in a population of pregnant patients without early history of trauma would help determine what amount of free fluid should raise suspicion of intra-abdominal injury in those who have suffered trauma. ⋯ These results suggest that the presence of pelvic free fluid in pregnant patients without antecedent trauma is very low. After blunt abdominal trauma, the presence of free fluid in the pelvis of a pregnant patient may not be physiologic, especially if there is >2 mm to 4 mm, and there is no history of ovarian hyperstimulation syndrome or other known associations.

Endotoxemia from lipopolysaccharide (LPS) induces systemic cytokine production, whereas traumatic brain injury (TBI) increases intracerebral cytokine production. In anesthetic doses, ketamine has potent anti-inflammatory properties. However, its anti-inflammatory effects at subanesthetic doses and its effects on TBI-induced inflammation have not been fully investigated. We hypothesized that ketamine would attenuate both LPS- and TBI-induced inflammatory responses. ⋯ Although ketamine did not seem to exert any beneficial effects against TBI in the rat, it did not exacerbate cytokine production or enhance cerebral edema as some studies have suggested.

Screening for mental illness in a trauma center: rooting out a risk factor for unintentional injury.
Injury prevention and screening efforts have long targeted risk factors for injury recurrence. In a retrospective study, our group found that mental illness is an independent risk factor for unintentional injury and reinjury. The purpose of this study was to administer a standard validated screening instrument and psychosocial needs assessment to admitted patients who suffer unintentional injury. We aimed to prospectively measure the prevalence of mental illness. We hypothesize that systematic screening for psychiatric disorders in trauma patients is feasible and identifies people with preexisting mental illness as a high-risk group for unintentional injury. ⋯ This inpatient pilot screening program prospectively identified preexisting mental illness as a risk factor for unintentional injury. Implementation of validated psychosocial and mental health screening instruments is feasible and efficient in the acute trauma setting. Administration of a validated mental health screening instrument can be achieved by training college-level research assistants. This system of screening can lead to identification and treatment of mental illness as a strategy for unintentional injury prevention.

Randomized Controlled Trial Multicenter Study
Quality of life after severe trauma: results from the global trauma trial with recombinant Factor VII.
Physical disability and psychologic morbidity are frequent and important complications of severe trauma injury with serious consequences for long-term health-related quality of life (HRQOL). Little prospective data exist, however, in a global trauma population on the risk factors for poor HRQOL. ⋯ Three months after severe trauma injury, survivors report very poor HRQOL. Physical wellbeing is generally more negatively affected than mental wellbeing. A trauma-specific HRQOL instrument reveals more diverse mental health problems than generic instruments. In a global trauma population, postinjury HRQOL is predicted by demographic and socioeconomic characteristics, type of injury, and treatment received.
