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.

Many trauma centers have separated emergency and general surgery from trauma care. However, decreased trauma volume and more frequent nonoperative management may limit operative experience and the economic viability of the trauma service. Trauma surgeons at our Level I trauma center have long provided all emergency surgical care and elective surgery. We sought to determine the impact of this policy. ⋯ Maintenance of emergency and general surgical care by the trauma service has allowed us to buffer impact of variations in trauma volume and to maintain operative skills in an era of increased nonoperative management of many injuries.

The potential to modulate the inflammatory response has renewed interest in hypertonic saline (HTS) resuscitation of injured patients. However, the effect of the timing of HTS treatment with respect to polymorphonuclear neutrophil (PMN) priming and activation remains unexplored. We hypothesized that HTS attenuation of PMN functions requires HTS exposure before priming and activation. ⋯ The timing of HTS is a key variable in the attenuation of PMN cytotoxic functions. Maximal attenuation of cytotoxicity is achieved before priming, whereas HTS exposure after activation augments cytotoxicity.

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.
