Review Case Reports
Bronchial blocker placement through the lumen of an in situ tracheal tube.
Tracheal intubation during trauma resuscitation is almost always performed with a standard endotracheal tube. Difficulties may arise if lung isolation is required later. The options for achieving lung isolation in seriously traumatized patients are briefly reviewed. Two efficient and airtight systems to allow the insertion of a bronchial blocker with minimal risks are presented.

The Abbreviated Injury Scale (AIS), developed by the Association for the Advancement of Automotive Medicine is the most widely used anatomic injury severity scale in the world (Association for the Advancement of Automotive Medicine. The Abbreviated Injury Scale; 1985 and 1990 revisions. Des Plaines, IL: Association for the Advancement of Automotive Medicine). However, different user groups have modified the AIS system to fit their needs, and these modifications prevent ready comparison and trending of data collected in these systems in the United States and throughout the world. The United States currently has five AIS-based severity systems and two AIS-based impairment systems in use, with additional revisions forthcoming. Other modified AIS systems are known to be in use in the United Kingdom and Japan. The data collected in these systems cannot be accurately combined or compared without re-coding or the use of complex "mapping" methodologies. Furthermore, the expanding use of data linked from multiple databases to answer complex medical, engineering, or policy issues emphasizes the need for coordination between severity and other injury systems. Linkage of state-wide motor vehicle crash data with data from hospital injury classification systems, mortality files, trauma registry, and national crash databases brings into immediate focus the lack of well defined relationships between the severity coding systems and these other widely used injury systems (Mango N, Garthe E. SAE Congress, February, 1998; Johnson, S, Walker, J. NHTSA Technical Report. DOT HS 808 338, Washington, DC: NHTSA; January, 1996). With the expanding use of linked data in state and national policy decisions, it is vital that consistent standards for injury descriptions, severities, and impairments be available for clinical, engineering, and policy users. ⋯ The authors believe that a "unified" injury system is a necessary and crucial advance from the currently fragmented injury system situation. Unified data can provide a pool of consistent international data to support a variety of important research and prevention and treatment efforts and is essential to satisfy the global needs of the medical and engineering communities.

Handguns are a ubiquitous consumer product in the United States, which annually cause significant morbidity and mortality. Handgun safety devices are often proposed as potential solutions to this problem. Their effectiveness at reducing handgun injuries and deaths is intensely debated. However, to effectively analyze the potential utility of handgun safety devices, physicians need to be aware of the safety devices available in the consumer market and how they operate. ⋯ Physicians have the potential to reduce the risk of firearm injuries with their patients and communities. Providing accurate information on firearm safety devices and their limitations is important, just as it is for other aspects of health care advice. Armed with accurate information, physicians can hopefully be effective in firearm injury prevention.

Review Case Reports
Detection of vertebral artery injury after cervical spine trauma using magnetic resonance angiography.
We prospectively describe the incidence, magnetic resonance-based diagnosis, and treatment of vertebral artery (VA) injury resulting from closed cervical spine trauma. ⋯ Our data suggest that the incidence of VA injury in closed cervical spine trauma is significant and that FT fractures warrant flow-sensitive magnetic resonance imaging.
