Review Comparative Study
Chest Pain of Suspected Cardiac Origin: Current Evidence-based Recommendations for Prehospital Care.
In the United States, emergency medical services (EMS) protocols vary widely across jurisdictions. We sought to develop evidence-based recommendations for the prehospital evaluation and treatment of chest pain of suspected cardiac origin and to compare these recommendations against the current protocols used by the 33 EMS agencies in the state of California. ⋯ Protocols for chest pain of suspected cardiac origin vary widely across California. The evidence-based recommendations that we present for the prehospital diagnosis and treatment of this condition may be useful for EMS medical directors tasked with creating and revising these protocols.

Randomized Controlled Trial
A Simulation-based Randomized Controlled Study of Factors Influencing Chest Compression Depth.
Current resuscitation guidelines emphasize a systems approach with a strong emphasis on quality cardiopulmonary resuscitation (CPR). Despite the American Heart Association (AHA) emphasis on quality CPR for over 10 years, resuscitation teams do not consistently meet recommended CPR standards. The objective is to assess the impact on chest compression depth of factors including bed height, step stool utilization, position of the rescuer's arms and shoulders relative to the point of chest compression, and rescuer characteristics including height, weight, and gender. ⋯ Rescuer arm position relative to the patient's chest and step stool utilization during CPR are modifiable factors facilitating improved chest compression depth.

Airway management in critically ill patients involves the identification and management of the potentially difficult airway in order to avoid untoward complications. This focus on difficult airway management has traditionally referred to identifying anatomic characteristics of the patient that make either visualizing the glottic opening or placement of the tracheal tube through the vocal cords difficult. ⋯ The four physiologically difficult airways described include hypoxemia, hypotension, severe metabolic acidosis, and right ventricular failure. The emergency physician should account for these physiologic derangements with airway management in critically ill patients regardless of the predicted anatomic difficulty of the intubation.

Despite evidence from other healthcare settings that language barriers negatively impact patient outcomes, the literature on language barriers in emergency medical services (EMS) has not been previously summarized. The objective of this study is to systematically review existing studies of the impact of language barriers on prehospital emergency care and identify opportunities for future research. ⋯ The existing research on prehospital language barriers is largely exploratory, and substantial gaps in understanding the interaction between language barriers and prehospital care have yet to be addressed. Future research should be focused on clarifying the clinical and cost implications of prehospital language barriers.

Multicenter Study Comparative Study
Direct Versus Video Laryngoscopy for Intubating Adult Patients with Gastrointestinal Bleeding.
Video laryngoscopy (VL) has been advocated for several aspects of emergency airway management; however, there are still concerns over its use in select patient populations such as those with large volume hematemesis secondary to gastrointestinal (GI) bleeds. Given the relatively infrequent nature of this disease process, we sought to compare intubation outcomes between VL and traditional direct laryngoscopy (DL) in patients intubated with GI bleeding, using the third iteration of the National Emergency Airway Registry (NEARIII). ⋯ In this national registry of intubations performed in the ED for patients with GI bleeds, both DL and VL had similar rates of success, glottic views and need to change devices.
