Conventional emergency medical services (EMS) guidelines recommend that essentially every victim of any significant trauma be treated in the field as having an unstable spine injury. For example, any victim of any motor vehicle crash generally is assumed to have an unstable spine injury and is transported to the hospital in full-spine immobilization. This approach generally is reasonable and appropriate for the conventional EMS context of rapid transport, because patient symptoms and physical examination often are unreliable for the time period immediately following the event.

The specialized context of delayed or prolonged transport, however, requires a closer look at assessment criteria and treatment procedures for spine injury. Full-spine immobilization, if it is not required, can be unnecessarily difficult, impractical, impossible, and even dangerous during prolonged evacuation, especially in severe environments or when using improvized equipment. Prolonged transport also provides an opportunity to repeat patient surveys and to observe changes in the patient's condition over time.

Disaster managers should be familiar with certain technologies or sets of information used in disaster management. Among the more important are mapping, interpretation of aerial photography, communications, information management, logistics and computer applications, epidemiology, and preventive medicine.

Exposure to radiation induces a reduction in the number of gastrointestinal, anaerobic bacterial flora, and an increase in the number of Enterobacteriaceae that are associated with sepsis and mortality. Antimicrobials that suppress anaerobic flora have a deleterious effect on survival by promoting earlier enterobacterial sepsis. In contrast, in studies of animals and immunosuppressed patients, antimicrobials that inhibit gram-negative enteric bacteria and preserve the anaerobic flora have shown a beneficial effect by preventing bacterial translocation and fatal sepsis. The quinolone antimicrobials hold potential for therapy of endogenous and exogenous infection after irrodiation.
