Review Case Reports
Pediatric transesophageal echocardiography in the evaluation of acute disruption of the mitral valve following blunt thoracic trauma: case report.
Disruption of the mitral valve following blunt thoracic trauma has been only occasionally reported. A case of a pediatric patient with this complication is presented and the value of transesophageal echocardiography in diagnosis and management is documented.

Review Case Reports
Baluster entrapment avulsion of the little finger: a new clinical entity--case reports.
Five cases of avulsion injuries of the little finger are described. The mechanism of injury was identical in all cases. The little finger was entrapped by a baluster when the patient frantically attempted to grasp the handrail to avoid falling down stairs. To our knowledge, this type of injury has not been reported previously.

Review Case Reports
Successful roadside resuscitative thoracotomy: case report and literature review.
Patients with injuries severe enough to require cardiopulmonary resuscitation (CPR) have a dismal prognosis. Time to surgical intervention is a major determinant of outcome in moribund trauma patients who have a potential for survival. With the exception of endotracheal intubation during evacuation to surgical intervention, no other usual prehospital procedures have been validated to affect outcome in such cases of extremis. ⋯ The patient recovered fully and was discharged home in 21 days, neurologically intact. Four years later, the patient was alive, healthy, and working. This report demonstrates the feasibility of prehospital thoracotomy and raises provocative issues regarding future intense surgical involvement in prehospital care.

Case Reports
Transesophageal echocardiography in the evaluation of a transmediastinal gunshot wound: case report.
Transesophageal echocardiography is a safe, minimally invasive imaging modality that may be useful in the evaluation of transmediastinal gunshot wounds. In this report, we describe a hemodynamically stable patient who sustained a gunshot wound to the ascending aorta. Routine diagnostic evaluation, including aortography, failed to confirm the suspected diagnosis. Transesophageal echocardiography definitively detailed the injury to the aorta enabling definitive surgical repair.

Comparative Study
Resuscitation from hypovolemia in swine with intraosseous infusion of a saturated salt-dextran solution.
Prehospital fluid resuscitation of traumatic injury is limited by difficulty in delivering large volumes of fluid in the field and time delays associated with gaining vascular access. We addressed these limitations in 14 anesthetized swine by evaluating a highly efficient volume expander, a near-saturated salt-dextran solution (SSD) administered through a new device, which gains vascular access via intraosseous (IO) infusion into the sternal bone marrow. After a steady-state baseline was achieved, all animals were hemorrhaged to 45 mm Hg for one hour. ⋯ In addition, cardiac output was better sustained after 2 hours with SSD than with NS. No deleterious effects of IO infusion of SSD were observed. From the improvement in cardiovascular variables and the lack of significant sternal or pulmonary pathologic perturbations, these data suggest that IO infusion of SSD can effectively treat hypovolemia and may allow field treatment when logistic considerations make conventional resuscitation impractical.
