Comparative Study
Prospective analysis of a rapid trauma ultrasound examination performed by emergency physicians.
The objective of this prospective study was to determine the sensitivity, specificity, and accuracy of the rapid trauma ultrasound examination, performed by emergency physicians, for detecting free peritoneal and thoracic fluid in patients presenting to a level I trauma center with major blunt or penetrating torso trauma. Emergency medicine residents and faculty were trained to perform an ultrasound examination of the torso evaluating for free intraperitoneal, retroperitoneal, pleural, and pericardial fluid. ⋯ Ultrasonography can serve as an accurate diagnostic adjunct in detecting free peritoneal and thoracic fluid in trauma patients. Appropriately trained emergency physicians can accurately perform and interpret these trauma ultrasound examinations.

Pulmonary embolism in reamed femoral nailing has been reported and discussed over recent years. Does an unreamed nailing technique with a solid nail prevent this rare but serious complication of intramedullary fixation? In an animal model in rabbits, we studied the pathophysiologic impact on pulmonary function and the impact on hemostasis of reamed and unreamed nailing of intact femora and tibiae, and of femoral fracture in relation to intramedullary pressure. No statistical difference of PaO2, PaCO2, and PCO2et was found in the femur whether a reamed or unreamed procedure was performed. ⋯ Intramedullary pressure was increased in all animals with perioperative impairment of pulmonary function (375 to 676 mbar). Analysis of the hemostatic results showed a significant difference of platelet activation in reamed versus unreamed nailing of the femur 1 hour after nailing (p < 0.01) and a significant decrease of fibrinogen and antithrombin III (p < 0.001/p < 0.01) in reamed femoral nailing. We conclude that unreamed nailing of the femur with a solid rod may also cause bone marrow embolization with alteration of pulmonary function as long as an important increase of the intramedullary pressure is generated during the nailing procedure.(ABSTRACT TRUNCATED AT 250 WORDS)

The demographics and outcome of patients with gunshot wounds to the head over the past 10 years at Chicago's Cook County Hospital was examined. The study group consisted of 476 consecutive patients admitted to this urban level I trauma center with a diagnosis of penetrating craniocerebral missile injury. All patients followed a protocol that included aggressive surgical management when indicated. ⋯ A large proportion of this violence is most likely attributable to gang activity. Factors correlating with poor outcome included hypotension, apnea, bihemispheric injuries, or ventricular penetration. Although aggressive surgical and medical management improves the outcome of these patients, much more stringent preventative measures are required to control this violent epidemic.

To determine the usefulness of early echocardiography in stable patients with penetrating wounds in proximity to the heart. ⋯ Using the protocol of early ECHO and selective pericardial window, no clinically significant injuries were missed. In all, 12 penetrating cardiac injuries were identified and repaired successfully. We have found early and aggressive work-up, as outlined herein, to be helpful in the successful treatment of occult cardiac injuries.

To assess the teaching effectiveness of the Advanced Trauma Life Support (ATLS) Program among senior medical students. ⋯ Using highly reliable trauma OSCE stations we have demonstrated trauma management skills acquisition by senior medical students after the ATLS course.
