This study was designed to investigate the epidemiology and prognostic factors determining survival in penetrating injuries of the aorta. ⋯ Penetrating aortic injuries still have a very high mortality rate with no improvement in survival despite improved trauma services. Injury to the thoracic aorta, gunshot wounds, unrecordable blood pressure on admission, and the need for emergency room thoracotomy, are important predictors of high mortality.

To quantify the occurrence of arterial hypotension and arterial oxygen desaturation in a series of patients with head trauma rescued by helicopter. ⋯ Hypoxemia and shock are frequent findings on patients at the accident scene. Hypoxemia is more frequently detected and promptly corrected, white arterial hypotension is more difficult to control. Both insults may have a significant impact on outcome.
