Effect of spinal immobilization on heart rate, blood pressure and respiratory rate.
Vital signs remain important clinical indicators in the management of trauma. Tissue injury and ischemia cause tachycardia and hypertension, which are mediated via the sympathetic nervous system (SNS). Spinal immobilization is known to cause discomfort, and it is not known how this might influence the SNS and contribute to abnormal vital signs. Hypothesis This study aimed to establish whether the pain and discomfort associated with spinal immobilization and the maneuvers commonly used in injured patients (eg, log roll) affect the Heart rate (HR), Systolic Blood Pressure (SBP) and Respiratory rate (RR). The null hypothesis was that there are no effects. ⋯ Pain VAS increased significantly during spinal immobilization (3.8 mm, P < .01). Discomfort VAS increased significantly during spinal immobilization, after log roll and during partial immobilization (17.7 mm, 5.8 mm and 8.9 mm, respectively; P < .001). Vital signs however, showed no clinically relevant changes. Discussion Spinal immobilization does not cause a change in vital signs despite a significant increase in pain and discomfort. Since no relationship appears to exist between immobilization and abnormal vital signs, abnormal vital signs in a clinical situation should not be considered to be the result of immobilization. Likewise, pain and discomfort in immobilized patients should not be disregarded due to lack of changes in vital signs.

Comparative StudyPrehospital mass-casualty triage training-written versus moulage scenarios: how much do EMS providers retain?
The aim of this study was to assess the effectiveness of written and moulage scenarios using video instruction for mass-casualty triage by evaluating skill retention at six months post intervention. ⋯ These data confirm the skill deterioration associated with an infrequently used triage method. Further research to more precisely define triage criteria, as well as the ability to apply the criteria in a clinical setting and to rapidly identify patients at risk for morbidity/mortality is needed.

Historical ArticleInitial management of hospital evacuations caused by Hurricane Rita: a systematic investigation.
Hurricanes remain a major threat to hospitals throughout the world. The authors attempted to identify the planning areas that impact hospital management of evacuations and the challenges faced when sheltering-in-place. ⋯ Hospital EDs should plan for continuous patient arrival during evacuation. Emergency Operation Plans (EOPs) that anticipate challenges associated with evacuation will help to maximize initial decision making and management during a crisis situation. Hospitals that shelter-in-place face critical shortages and must provide independent patient care for prolonged periods.

Serving limited English proficient callers: a survey of 9-1-1 police telecommunicators.
The emergency telephone number 9-1-1 serves as a lifeline to the public during emergencies, and first responders rely on information gathered by 9-1-1 telecommunicators who speak with callers. Timely, accurate information from the telecommunicators is essential for providing appropriate care on scene. Language barriers can hamper these efforts and result in less efficient information exchange. Although 9-1-1 telecommunicators may access over-the-phone interpreter (OPI) services to facilitate communication, managing three-way communication during an emergency is challenging. Problem There is little published on the relationship between limited English proficient (LEP) callers and 9-1-1 police telecommunicators, and the role of OPI services during these calls. Further, little is known about effective strategies to manage such calls. ⋯ These results highlight intervention opportunities for both 9-1-1 telecommunicators and LEP communities. Together, interventions such as working with LEP communities to educate them on best communication practices during 9-1-1 calls, and with 9-1-1 telecommunicators to help them manage three-way communication and reduce stress associated with concern for officer safety may improve emergency communication during 9-1-1 calls.

Holy Shroud Exhibition 2010: health services during a 40-day mass-gathering event.
Mass-gathering events require varying types and amounts of medical resources to deal with patient presentations as well as careful planning for environmental health management. The Holy Shroud Exhibition was hosted in Torino, Italy, between April and May 2010. The venue was a unique mass-gathering event which lasted several weeks. It was held in a limited area in the center of the city and it was attended by a large and heterogeneous population. A dedicated Health Care Service was created for the event. ⋯ The experience for this 40-day event supported having an on-site, organized, dedicated Medical Service that decreased overcrowding of the local Emergency Medical System and hospitals. It is recommended that, for such events, there be recruitment of emergency physicians with experience in mass-gathering events, recruitment of pediatricians, and training for professionals during the planning process.
