Because of the need to improve the quality of care of trauma patients in our country, we decided to evaluate the epidemiology and find the most powerful tool for prediction of survival. The Trauma and Injury Severity Score (TRISS) has been known as conventional method for this purpose. We planned to test its ability for prediction of survival of our trauma patients, and also we wanted to compare its ability with the New Injury Severity Score (NISS) in combination with Revised Trauma Score (RTS) and age. We used the most suitable model to evaluate the trauma care in our centers. ⋯ Based on our descriptive findings, we proposed some suggestions that seem to be necessary for improvement of trauma care in our centers. Among them were improved measures for prehospital service, and emergency department and other health care units of our centers. The findings of this study suggest that conducting trauma surgery training programs and direct transportation to trauma centers can improve the outcome of trauma patients. We conclude that small sample size, mixing penetrating trauma cases with blunt trauma cases, and differences in the mechanism of trauma between study populations may be responsible for the difference between our results and others.

The circumstances of failure for nonoperative management of blunt traumatic brain injury have been poorly defined. In this study, all trauma patients identified over a 12-year period with progression of neurologic injury requiring craniotomy were retrospectively reviewed. ⋯ Of the variables investigated, only anatomic location of injury was found to be predictive of early failure of nonoperative management. Frontal intraparenchymal hematomas are particularly prone to early failure. Clinical examination and intracranial pressure monitoring are equally important in detecting failure and should be an integral part of nonoperative management.

To evaluate admission systolic blood pressure (SBP) in the emergency center (EC) as a means by which patients with transmediastinal gunshot wounds (TM-GSWs) can be triaged to the operating room versus further diagnostic evaluation. ⋯ The diagnosis of TM-GSW for patients in groups I and II is confirmed by finding at physical examination and on chest x-ray films in 90% of cases. In the absence of obvious bleeding, patients with TM-GSWs and SBP > 100 mm Hg may safely undergo further diagnostic evaluation. Sixty percent of such patients did not require an operation. All patients with TM-GSWs and SBP < 60 mm Hg (group III) require immediate operation. For patients with TM-GSWs, SBP from 60 to 100 mm Hg (group II), and without obvious bleeding, it is the response to resuscitation and the results of further diagnostic evaluation that determine the need for operation. Fifty percent of such patients did not require operation.

The sequelae of blunt injury to the carotid arteries are unusual, but pseudoaneurysms causing subsequent strokes are devastating. The utility of treatment of these pseudoaneurysms was examined. ⋯ Use of metallic endoprostheses is an effective method to treat this potentially devastating injury. However, longer follow-up and more patients studied are needed to further examine this promising treatment.

Induced hypothermia is used clinically to prevent ischemic injury during elective procedures. We present an animal model of asanguinous hypothermic (10 degrees C) circulatory arrest, induced through a left anterior lateral thoracotomy after exsanguinating uncontrolled hemorrhage. ⋯ Induction of hypothermic arrest through the chest after exsanguination is possible. The further development of this technique may provide an extended state of "suspended animation" to allow for repairs of hemorrhaging injuries in trauma patients who require emergency department thoracotomy.
