Randomized Controlled Trial Comparative Study
Comparison of Fentanyl and Morphine in the Prehospital Treatment of Ischemic Type Chest Pain.
In the treatment of acute coronary syndromes, reduction of sympathetic stress and catecholamine release is an important therapeutic goal. One method used to achieve this goal is pain reduction through the systemic administration of analgesia. Historically, morphine has been the analgesic of choice in ischemic cardiac pain. ⋯ There were no significant differences between the changes in visual analog scores and numeric rating scale scores for pain between the two groups (p = 0.16 and p = 0.15, respectively). This study supports that fentanyl and morphine are comparable in providing analgesia for ischemic-type chest pain. Fentanyl appears to be a safe and effective alternative to morphine for the management of chest pain in the prehospital setting.

Pain is the most common symptom in the emergency setting and remains one of the most challenging problems for emergency care providers, particularly in the pediatric population. The primary objective of this study was to determine the prevalence of acute pain in children attending emergency departments (EDs) in Ireland by ambulance. In addition, this study sought to describe the prehospital and initial ED management of pain in this population, with specific reference to etiology of pain, frequency of pain assessment, pain severity, and pharmacological analgesic interventions. ⋯ Upon ED arrival 54% (n = 1,422) of children had a documented pain assessment and some form of analgesic agent was administered to 50% (n = 1,324). Approximately 41% of children who attend EDs in Ireland by ambulance have pain documented as their primary symptom. This study suggests that the management of acute pain in children transferred by ambulance to the ED in Ireland is currently poor, with documentary evidence of only 26% receiving prehospital analgesic agents.

Observational Study
Achieving a Safe Endotracheal Tube Cuff Pressure in the Prehospital Setting: Is It Time to Revise the Standard Cuff Inflation Practice?
Numerous studies have reported unsafe endotracheal tube (ETT) cuff pressures (CP) in the prehospital environment. The purpose of this study was to identify an optimal cuff inflation volume (CIV) to achieve a safe CP (20-30 cmH2O). This observational study utilized 30 recently harvested ovine tracheae, which were warmed from refrigeration in a water bath at 85°F prior to testing. ⋯ Our study showed a high frequency of CP measurements outside of the desired norms. The CIV range of 6-7 cc resulted in the highest likelihood of achieving the desired cuff pressure range, while cuffs inflated with 8-10 cc resulted in dangerously high CPs in all instances. In the absence of a more ideal solution, the results of this study suggest that narrowing the recommended CIV from 5-10 cc to 6-7 cc might be a reasonable target for any tube size.

Case Reports
Differences in Paramedic Fatigue before and after Changing from a 24-hour to an 8-hour Shift Schedule: A Case Report.
Emergency medical services (EMS) clinicians often work 24-hour shifts. There is a growing body of literature, with an elevated level of concern among EMS leaders that longer shifts contribute to fatigued workers and negative safety outcomes. However, many questions remain about shift length, fatigue, and outcomes. ⋯ He also reported perceived fatigue, sleepiness, and difficulty with concentration at the beginning, every 4 hours during, and at the end of scheduled shifts, for a total of ten 24-hour shifts and twenty-four 8-hour shifts. We discuss differences in measures taken before and after switching shift schedules, and highlight differences in fatigue, sleepiness, and difficulty with concentration taken at the end of all 34 scheduled shifts stratified by shift duration (24 hours versus 8 hours). Findings from this case report present a unique opportunity to 1) observe and analyze a phenomenon that has not been investigated in great detail in the EMS setting; and 2) address an issue of significance to employers and EMS clinicians alike.

Multiple national organizations have recommended and supported a national investment to increase the scientific evidence available to guide patient care delivered by Emergency Medical Services (EMS) and incorporate that evidence directly into EMS systems. Ongoing efforts seek to develop, implement, and evaluate prehospital evidence-based guidelines (EBGs) using the National Model Process created by a multidisciplinary panel of experts convened by the Federal Interagency Committee on EMS (FICEMS) and the National EMS Advisory Council (NEMSAC). Yet, these and other EBG efforts have occurred in relative isolation, with limited direct collaboration between national projects, and have experienced challenges in implementation of individual guidelines. ⋯ Other action items include promoting research that supports creation and evaluates the impact of EBGs, promoting the development of new EBGs through improved stakeholder collaboration, and improving education on evidence-based medicine for all prehospital providers. The Strategy intends to facilitate implementation of EBGs by improving guideline dissemination and incorporation into protocols, and seeks to establish standardized evaluation methods for prehospital EBGs. Finally, the Strategy proposes that key stakeholder organizations financially support the Prehospital Guidelines Consortium as a means of implementing the Strategy, while together promoting additional funding for continued EBG efforts.
