Review Historical ArticleMustard gas or sulfur mustard: an old chemical agent as a new terrorist threat.
Sulfur mustard is a member of the vesicant class of chemical warfare agents that causes blistering to the skin and mucous membranes. There is no specific antidote, and treatment consists of systematically alleviating symptoms. ⋯ Longitudinal studies of exposed victims show that sulfur mustard causes long-term effects leading to high morbidity. Given that only a small amount of sulfur mustard is necessary to potentially cause an enormous number of casualties, disaster-planning protocol necessitates the education and training of first-line healthcare responders in the recognition, decontamination, triage, and treatment of sulfur mustard-exposed victims in a large-scale scenario.

ReviewEarthquakes and trauma: review of triage and injury-specific, immediate care.
Earthquakes present a major threat to mankind. Increasing knowledge about geophysical interactions, progressing architectural technology, and improved disaster management algorithms have rendered modern populations less susceptible to earthquakes. Nevertheless, the mass casualties resulting from earthquakes in Great Kanto (Japan), Ancash (Peru), Tangshan (China), Guatemala, Armenia, and Izmit (Turkey) or the recent earthquakes in Bhuj (India), Bam (Iran), Sumatra (Indonesia) and Kashmir (Pakistan) indicate the devastating effect earthquakes can have on both individual and population health. ⋯ However, the main priorities of disaster rescue teams are the rescue and provision of emergency care for physical trauma. Furthermore, the establishment of transport evacuation corridors, a feature often neglected, is essential in order to provide the casualties with a chance for survival. The optimal management of victims under such settings is discussed, addressing injuries of the body and psyche by means of simple diagnostic and therapeutic procedures globally applicable and available.

ReviewPrinciples of disaster planning for the pediatric population.
Unique physiological, developmental, and psychological attributes of children make them one of the more vulnerable populations during mass-casualty incidents. Because of their distinctive vulnerabilities, it is crucial that pediatric needs are incorporated into every stage of disaster planning. Individuals, families, and communities can help mitigate the effects of disasters on pediatric populations through ongoing awareness and preventive practices. ⋯ Pediatric response can be improved in a number of ways, including: (1) enhanced pediatric disaster expertise; (2) altered decontamination protocols that reflect pediatric needs; and (3) minimized parent-child separation. Recovery efforts at the pediatric level include promoting specific mental health therapies for children and incorporating children into disaster relief and recovery efforts. Improving pediatric emergency care needs should be at the forefront of every disaster planner's agenda.

ReviewSurviving collapsed structure entrapment after earthquakes: a "time-to-rescue" analysis.
Massive earthquakes often cause structures to collapse, trapping victims under dense rubble for long periods of time. Commonly, this spurs resource intensive, dangerous, and frustrating attempts to find and extricate live victims. The search and rescue phase usually is maintained for many days beyond the last "save," potentially diverting critical attention and resources away from the pressing needs of non-trapped survivors and the devastated community. This recurring phenomenon is driven by the often-unanswered question "Can anyone still be alive under there?" The maximum survival time in entrapment is an important issue for responders, yet little formal research has been conducted on this issue. Knowing the maximum survival time in entrapment helps responders: (1) decide whether or not they should continue to assign limited resources to search and rescue activities; (2) assess the safety risks versus the benefits; (3) determine when search and rescue activities no longer are indicated; and (4) time and pace the important transition to community recovery efforts. ⋯ A thorough search of the English-language medical literature and media accounts provides a provocative picture of numerous survivors beyond 48 hours of entrapment under rubble, with a few successfully enduring entrapment of 13-14 days. These data are not necessarily applicable to non-earthquake collapsed-structure events. For incident managers and their medical advisors, the study findings and discussion may be useful for post-impact decision-making and in establishing and/or revising incident priorities as the response evolves.

Review Comparative StudyDoes advanced life support provide benefits to patients?: A literature review.
Emergency medical services have invested substantial resources to establish advanced life support (ALS) programs. However, it is unclear whether ALS care provides better outcomes to patients compared to basic life support (BLS) care. ⋯ ALS shows little, if any, benefits for urban trauma patients. Cardiac arrest studies show that ALS does not provide additional benefits over BLS-defibrillation care, but more research is needed in this area. In two small studies, ALS care did not provide benefits over BLS care for patients with myocardial infarctions or altered mental status. Larger-scale studies are needed to evaluate which specific ALS interventions improve patient outcomes.
