Recent studies have suggested that transesophageal echocardiography (TEE) can be used as the primary imaging method in patients suspected of traumatic rupture of the thoracic aorta. A segment of the aorta and the aortic arch branches cannot be adequately evaluated in all patients by TEE. To assess the impact of these limitations of TEE, this retrospective study examined the aortographic features of traumatic aortic or great vessel injuries in a large number of patients. ⋯ Twenty percent of patients in our retrospective series had traumatic involvement of aortic arch branches or the distal ascending aorta. These vascular injuries may be suboptimally assessed or overlooked if TEE is used as the sole imaging modality in the evaluation of patients with blunt chest trauma.

Focused abdominal sonography for trauma (FAST) relies on hemoperitoneum to identify patients with injury. Blunt trauma victims (BTVs) with abdominal injury, but without hemoperitoneum, on admission are at risk for missed injury. ⋯ Up to 29% of abdominal injuries may be missed if BTVs are evaluated with admission FAST as the sole diagnostic tool. Consideration of examination findings and associated injuries should reduce the risk of missed abdominal injury in BTVs with negative FAST results.

To compare differences in response times, scene times, and transport times by advanced life-support-trained paramedics to trauma incidents in urban and rural locations. ⋯ Response and transport times among professional, advanced life-support-trained paramedics responding to major trauma incidents are longer in rural areas, compared with urban areas.

Trauma has a high rate of recurrence, suggesting that some people are more injury-prone than others. This study was performed to evaluate some of the psychological and social factors that might influence the likelihood of traumatic injury. ⋯ Victims of trauma, both nonintentional, and especially intentional, have a high incidence of psychopathology. Victims of intentional trauma have significantly lower intelligence scores than either nonintentional injury or elective surgery patients. The high incidence of unemployment, alcohol abuse, and illicit drug use in victims of intentional injury might provide several opportunities for trauma prevention programs. Underlying psychological disorders will have to be addressed to reduce the likelihood of becoming a victim of trauma.

Initial small-volume hypertonic saline resuscitation of a combined hemorrhagic shock and head injury model was studied. ⋯ Less fluid was needed in the short- and long-term with HS resuscitation. Early intracranial pressure was higher with lactated Ringer's solution resuscitation, possibly in part owing to increased blood volume.
