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.

Blunt small bowel injury (SBI) may be difficult to diagnose accurately. Diagnostic delays are associated with increased morbidity and mortality. ⋯ There is significant variation in the diagnostic approach to the patient with suspected SBI. The perceived mortality of delayed diagnosis is much less than reported. Those surgeons with more experience or perception of greater morbidity and mortality from a delayed diagnosis are more aggressive. Further investigation into the diagnosis and treatment of this injury is needed.

Patients are surviving previously fatal injuries. Unique morbidities are occurring in these survivors. Anterior ischemic optic neuropathy represents a previously unrecognized cause of blindness in the trauma victim. We hypothesize that this phenomenon is caused by unique characteristics of optic edema/ pressure or decreased blood flow associated with massive resuscitation. ⋯ Prone positioning is known to be associated with an increased intraocular pressure. We postulate that the combination of massive resuscitation and prone positioning will increase the incidence of anterior ischemic optic neuropathy. As such, we recommend that prone positioning for adult respiratory distress syndrome be reserved for only those patients at risk of death.
