Paramedic electrocardiogram and rhythm identification: a convenient training device.
A common reason for utilizing local paramedics and the emergency medical services is for the recognition and immediate treatment of chest pain, a complaint that has multiple possible etiologies. While many of those complaining of disease processes responsible for chest pain are benign, some will be life-threatening and will require immediate identification and treatment. The ability of paramedics to not only perform field electrocardiograms (ECGs), but to accurately diagnose various unstable cardiac rhythms has shown significant reduction in time to specific treatments. Increasing the overall accuracy of ECG interpretation by paramedics has the potential to facilitate early and appropriate treatment and decrease patient morbidity and mortality. ⋯ A flip book with multiple ECG rhythms and definitions without the benefit of any outside support was not effective in improving paramedic identification of ECG rhythms on a post-test. Suggestions for further research include repeating the study with a larger sample size; utilizing a lecturer to explain how to use the flip book in the most efficient manner; reiterating how to read and interpret ECGs; and answering questions. Comparing test scores of paramedic students, and newly certified paramedics as opposed to veteran paramedics also may indicate that the flip books are more suited for one group over another.

Historical ArticleOne hundred years of railway disasters and recent trends.
Globally, railway transport is increasing steadily. Despite the adoption of diverse safety systems, major railway incidents continue to occur. Higher speeds and increased passenger traffic are factors that influence the risk of mass-casualty incidents and make railway crashes a reality that merits extensive planning and training. ⋯ Despite extensive crash avoidance and injury reduction safety systems, railway crashes occur on all continents, indicating that this type of incident must be accounted for in disaster planning and training. Better developed safety, crashworthiness, and rescue resources in North America and Europe may be factors explaining why the number of crashes and losses has stabilized and why the average number of people killed per disaster is lowest on these continents.

Fuel use in a large, dynamically deployed emergency medical services system.
Emergency medical services (EMS) systems are a central component of the healthcare system, particularly for older patients. As currently configured, EMS transport is fundamentally petroleum dependent. Petroleum scarcity is an emerging public health concern, particularly for patient transport. Little is known regarding EMS fuel use, potential impacts of scarcity on operations, or strategies to minimize these impacts. ⋯ In this EMS system, operations are fundamentally dependent on petroleum. Mileage estimates can serve as a baseline to evaluate interventions for reducing petroleum dependence and in contingency planning. As cost pressures increase and these interventions become more common, systematic evaluations will be important.

Transportation-related injuries and fatalities among emergency medical technicians and paramedics.
This is the first study using national data to evaluate transportation risks among emergency medical technicians (EMTs) and paramedics (to be referred to hereafter as "EMTs") in the United States. ⋯ The US national EMS system is built on the premise of having an unlimited supply of 20 year olds interested in, and dedicated to, the provision of EMS care. Not only do we not have an unlimited supply of 20 year olds, we may be rapidly losing our current workforce through clearly preventable risks such as transportation incidents.Emergency medical services workers face a rate of occupational injury that is much higher than the national average and transportation-related events are a significant component of that risk. Resources must be devoted to further research, and to the development and evaluation of interventions designed to mitigate these transportation-related hazards.

Randomized Controlled TrialEmergency Cricothyrotomy in Confined Space Airway Emergencies: A Comparison.
In confined-space airway emergencies, prehospital personnel may need to perform cricothyrotomy when conventional airway techniques cannot be utilized or have failed. This study is a prospective, cross-over, randomized controlled trial that compares two widely-known techniques using two commercially available kits. ⋯ Use of the Quicktrach™ kit resulted in the fastest time to placement, was placed correctly in the airway, and was preferred by each of the residents. Its small, simple,and sturdy design, with few parts and easy manipulation, allow the Quicktrach™ to be a valuable option in prehospital situations involving confined spaces. The Melker™ kit, with its many parts, and need for greater manipulation, is not as easily utilized or preferred in a confined space scenario.
