Prehospital and disaster medicine

During a medical emergency, the American public often relies on the expertise of emergency medical technicians (EMTs). These professionals face a number of occupational hazards, and the literature suggests that EMTs are at a greater risk of developing physical and mental stress-related disorders. The purpose of this paper is to systematically examine gaps in the extant literature and to present a theoretically driven conceptual model to serve as a basis for future intervention and research efforts. ⋯ High-risk alcohol and other drug use and post-traumatic symptomatology pose substantial risks for EMTs, and consequently, for the patients they serve. It is imperative that researchers develop and test a theoretically grounded model of risk and protective factors that will guide intervention development and future study. The model suggested in this paper, based on a comprehensive literature review and development of theory, represents a critical first step in the intervention research process.

Protection against cold in prehospital care-thermal insulation properties of blankets and rescue bags in different wind conditions.
In a cold, wet, or windy environment, cold exposure can be considerable for an injured or ill person. The subsequent autonomous stress response initially will increase circulatory and respiratory demands, and as body core temperature declines, the patient's condition might deteriorate. Therefore, the application of adequate insulation to reduce cold exposure and prevent body core cooling is an important part of prehospital primary care, but recommendations for what should be used in the field mostly depend on tradition and experience, not on scientific evidence. ⋯ The evaluated insulation ensembles might all be used for prehospital protection against cold, either as single blankets or in multiple layer combinations, depending on ambient temperatures. However, with extended outdoor, on-scene durations, such as during prolonged extrications or in multiple casualty situations, the results of this study emphasize the importance of using a windproof and compression resistant outer ensemble to maintain adequate insulation capacity.

Comparative StudyComparision of health needs of older people between affected rural and urban areas after the 2005 Kashmir, Pakistan earthquake.
On 08 October 2005, an earthquake measuring 7.6 on the Richter scale, struck Pakistan's autonomous state of Kashmir and part of Indian-administrated Kashmir.The official death toll in Pakistan was 79,000, and nearly 1,400 in Kashmir. This study reports the findings of a three-week health needs assessment to understand the needs of rural, older people postearthquake. This study was conducted in February 2006 in the Neelum Valley of Kashmir, Pakistan, four months after the earthquake. ⋯ This is the first study to compare the post-earthquake healthcare needs of older people in urban and rural settings. Findings highlight specific health needs and issues related to long-term, chronic disease management. Given the global pattern of aging of the population, it is important to strengthen the capacity to respond appropriately to medical disasters, which includes preparedness for treating the health needs of older people.

Fluid therapy in pediatric victims of the 2003 bam, Iran earthquake.
On 26 December 2003, at 05:26 hours, an earthquake of magnitude 6.6 (Richter scale) caused a disaster in the Bam region of Southeastern Iran, which had a population of approximately 102,000. In this study, the clinical and laboratory features and therapeutic interventions in pediatric (three months to 14 years) crush victims were analyzed. Determination of the type and amount of fluid therapy for prevention of acute renal failure (ARF) was the main aim of this study. ⋯ Early intravenous volume replacement may prevent both ARF and dialysis need that may develop on the basis of rhabdomyolysis. In adults, six liters or 12-14 liters of fluids for prophylaxis of ARF in crush syndrome, were suggested. In children, it seems that DL/EX ratio (delivered to expected ratio) is the best marker for evolution of IV fluid therapy in pediatric patients. In children with crush injuries, DL/EX ratio of >4.8 was sufficient for the prevention of ARF.

Unintentional injury outcomes secondary to pedestrian traffic crashes: a descriptive analysis from a major medical center.
An environment in which traffic regulations are not strictly enforced often is characterized by carnage from motor vehicular crashes resulting in severe injuries with unacceptably high mortality. The descriptive demographics and injury characteristics of pedestrian road crash victims presenting to a tertiary medical center in southwestern Nigeria are presented in order to provide baseline epidemiology as a first step in determining areas of potential mitigation for care of unintentional injuries. ⋯ This raises serious questions about the prehospital- and hospital-based emergency services for vehicular road crash victims in this environment, and confirms the World Health Organization findings that Africa has the highest rate overall for unintentional injury deaths. A system-wide program must be put in place that addresses proven prevention measures across all sectors of the community.
