Comparative Study
Base deficit in the elderly: a marker of severe injury and death.
Base deficit has been used as a marker of significant injury and to predict resource utilization and mortality. The significance of base deficit in trauma patients 55 years and older has not been specifically evaluated. The purpose of this study was to determine the utility of base deficit in assessing older trauma patients versus a younger cohort. ⋯ A base deficit of < or = -6 is a marker of severe injury and significant mortality in all trauma patients, but it is particularly ominous in patients 55 years and older. Patients older than 55 years may have significant injuries and mortality risk without manifesting a base deficit out of the normal range.

Comparative Study
Intracranial pressure monitor placement by midlevel practitioners.
The timely treatment of patients with head injuries is affected by the availability and commitment of neurosurgeons. Use of midlevel practitioners (MLPs) may permit more efficient neurosurgical coverage. Intracranial pressure monitoring is among the most frequently used neurosurgical procedures. The purpose of this study was to examine the placement of intracranial pressure (ICP) monitors by MLPs. ⋯ ICP monitor placement by MLPs is safe. Use of MLPs may aid neurosurgeons in providing prompt monitoring of patients with head injuries.

New Food and Drug Administration guidelines allow research to be done under an "exception to informed consent." These guidelines mandate advance public disclosure (PD) but provide no specifics for how to accomplish this task. This report outlines the history of informed consent in emergency care situations, highlights the Food and Drug Administration regulations for an exception to informed consent, and describes a stepwise approach with specific details of a PD program for a study using a blood substitute. This descriptive report can serve as a guideline for subsequent emergency care investigators in the development of a strategic plan for PD.

The purpose of this study was to prospectively examine the accuracy of contrast-enhanced spiral thoracic computed tomography (CEST-CT) for direct detection of traumatic aortic injury resulting from blunt thoracic trauma. ⋯ CEST-CT is a valuable ancillary study for the detection of traumatic aortic injury. Spiral computed tomography is accurate for the detection and localization of both hemomediastinum and direct signs of aortic injury.
