Randomized Controlled Trial
Comparison of four methods of paramedic continuing education in the management of pediatric emergencies.
Introduction: Finite resources limit the amount of time EMS agencies can dedicate to continuing education in pediatric emergencies. EMS instructors need effective, efficient, and affordable educational strategies for these high-risk, low frequency events. Objective: To compare the effectiveness of four training methods in management of pediatric emergencies for paramedics. ⋯ Conclusions: Although improvements in those skills included in the training were found in three groups, two hours of training in pediatric emergencies per year was insufficient to produce a substantial improvement overall. Expensive, high-fidelity simulators were not necessary for teaching pediatric resuscitation skills to paramedics; instructive scenarios using low-fidelity manikins and debriefings appear to be adequate. The content delivered by an online refresher course did not provide any improvement in performance as measured by simulated, case-based assessments.

Intranasal Ketamine as an Adjunct to Fentanyl for the Prehospital Treatment of Acute Traumatic Pain: Design and Rationale of a Randomized Controlled Trial.
Objective: Acute pain management is fundamental in prehospital trauma care. Early pain control may decrease the risk of developing post-traumatic stress disorder (PTSD) and chronic pain. Fentanyl and ketamine are frequently used off-label, but there is a paucity of comparative data to guide decision-making about treatment of prehospital severe, acute pain. ⋯ The outcomes in the follow-up study are satisfaction with life and development of PTSD or chronic pain at 90 days after injury. An intention-to-treat approach will be used. Conclusion: These studies will test the hypotheses that ketamine plus fentanyl, when compared to fentanyl alone, effectively manages pain, decreases opiate requirements, and decreases PTSD at 90 days.

Verbal Motivation vs. Digital Real-Time Feedback During Cardiopulmonary Resuscitation: Comparing Bystander CPR Quality in a Randomized and Controlled Manikin Study of Simulated Cardiac Arrest.
The use of smartphone applications increases bystander CPR quality as well as the use of telephone CPR protocols. The present prospective, randomized, controlled manikin trial analyses the effects of a smartphone application (PocketCPR©) on CPR quality in a bystander CPR scenario compared to a dispatcher-assisted telephone CPR with the additional use of a metronome and verbal motivation. Methods: 150 laypersons were included to perform 8-minute CPR on a manikin. ⋯ Median compression rate in the telephone + app-group was significantly elevated (108 min-1 [IQR 96-119 min-1]) compared to the telephone-group (78 min-1 [IQR 56-106 min-1]; p < 0.001) and the telephone + motivation-group (99 min-1 [IQR 91-101 min-1]; p < 0.001). Conclusions: The use of a smartphone application as well as verbal motivation by a dispatcher during telephone CPR leads to higher CPR quality levels compared to standard telephone CPR. Thereby, the use of the smartphone application mainly shows an increase in compression rate, while increased compression rate with simultaneously increased compression depth was only apparent in the telephone + motivation-group.

Comparison of Chest Compression Quality Between Transfer Sheet and Stretcher Use for Transporting Out-Of-Hospital Cardiac Arrest Patients in a High-Rise Building - A Randomized and Open-label Cross-over Design.
Stretchers are commonly used for transporting cardiac arrest patients, but their use may be limited in confined spaces, like elevators. Use of transfer sheet as an alternative has not been explored. We aimed to compare manual chest compression quality between these two methods. ⋯ The TS group showed shorter time intervals of simulation start-to-first-compression (TS: 13.9 [12.4-15.1] sec vs S90: 15.9 [13.3-16.4] sec, p = 0.04) and total run time (TS: 145.7 [135.1-151.4] sec vs S90: 160.0 [151.9-175.4] sec, p < 0.01) than the S90 group. Conclusion: In this simulation, using transfer sheet outperform using stretcher for transporting cardiac arrest patients from high-rise buildings. Rescuers need to be aware of full chest recoil.

Randomized Controlled Trial
Ability of Layperson Callers to Apply a Tourniquet Following Protocol-Based Instructions from an Emergency Medical Dispatcher.
Introduction: One of the greatest casualty-care improvements resulting from US military operations in Iraq and Afghanistan has been the reduction of preventable death from massive extremity hemorrhage - largely due to the widespread use of limb tourniquets. More recently, tourniquet use in civilian, prehospital settings has shown promise in reducing deaths in cases of catastrophic arterial limb hemorrhage. Telephone instructions by trained emergency medical dispatchers (EMDs) on applying an available tourniquet may help achieve such a benefit. ⋯ Median tourniquet pressure was 256 mmHg and median-end blood loss was 1,365 mL. A total of 198 participants (80.49%) were able to completely stop the bleeding while 16 participants (6.5%) had the tourniquet applied with some bleeding still occurring, and 32 participants (13.01%) exceeded the threshold of 2,500 mL of blood loss, resulting in the "patient" not surviving. Conclusions: The study findings demonstrated that untrained bystanders provided with instructions via phone from a trained Emergency Medical Dispatcher applied a tourniquet and successfully stopped the bleeding completely in most cases.
