Medical Oversight, Educational Core Content, and Proposed Scopes of Practice of Wilderness EMS Providers: A Joint Project Developed by Wilderness EMS Educators, Medical Directors, and Regulators Using a Delphi Approach.

INTRODUCTION: A disparity exists between the skills needed to manage patients in wilderness EMS environments and the scopes of practice that are traditionally approved by state EMS regulators. In response, the National Association of EMS Physicians Wilderness EMS Committee led a project to define the educational core content supporting scopes of practice of wilderness EMS providers and the conditions when wilderness EMS providers should be required to have medical oversight. METHODS: Using a Delphi process, a group of experts in wilderness EMS, representing educators, medical directors, and regulators, developed model educational core content. This core content is a foundation for wilderness EMS provider scopes of practice and builds on both the National EMS Education Standards and the National EMS Scope of Practice Model. These experts also identified the conditions when oversight is needed for wilderness EMS providers. RESULTS: By consensus, this group of experts identified the educational core content for four unique levels of wilderness EMS providers: Wilderness Emergency Medical Responder (WEMR), Wilderness Emergency Medical Technician (WEMT), Wilderness Advanced Emergency Medical Technician (WAEMT), and Wilderness Paramedic (WParamedic). These levels include specialized skills and techniques pertinent to the operational environment. The skills and techniques increase in complexity with more advanced certification levels, and address the unique circumstances of providing care to patients in the wilderness environment. Furthermore, this group identified that providers having a defined duty to act should be functioning with medical oversight. CONCLUSION: This group of experts defined the educational core content supporting the specific scopes of practice that each certification level of wilderness EMS provider should have when providing patient care in the wilderness setting. Wilderness EMS providers are, indeed, providing health care and should thus function within defined scopes of practice and with physician medical director oversight.

Impact of a pressure-responsive flow-limiting valve on bag-valve-mask ventilation in an airway model.

OBJECTIVE: Using a simulated airway model, we compared ventilation performance by emergency medical services (EMS) providers using a traditional bag-valve-mask (Easy Grip) resuscitator to their performance when using a new device, the SMART BAG resuscitator, which has a pressure-responsive flow-limiting valve. METHODS: We recruited EMS providers at an EMS educational forum and performed a randomized, non-blinded, prospective crossover comparison of ventilation with 2 devices on a non-intubated simulated airway model. Subjects were instructed to ventilate a Mini Ventilation Training Analyzer as they would an 85-kg adult patient in respiratory arrest. After being randomized to order of device use, they performed ventilation for 1 minute with each device. Primary outcomes were ventilation rates and peak airway pressures. We also measured average tidal volume, gastric inflation volume, minute ventilation and inspiratory:expiratory (I:E) ratio, and compared our results to the American Heart Association standards (2005 edition). RESULTS: We observed statistically significant differences between the SMART BAG and the traditional bag-valve-mask for respiratory rate (12 v. 14 breaths/min), peak airway pressure (15.6 v. 18.9 cm H(2)O), gastric inflation (239.6 v. 1598.4 mL), minute ventilation (7980 v. 8775 mL), and I:E ratio (1.3 v. 1.1). Average tidal volume was similar with both devices (679.6 v. 672.2 mL). CONCLUSION: The SMART BAG(R) provided ventilation performance that was more consistent with American Heart Association guidelines and delivered similar tidal volumes when compared with ventilation with a traditional bag-valve-mask resuscitator.

Lemierre syndrome in a child with recent pharyngitis.

A 14-year-old boy presented with fever and progressive respiratory distress, one week after an episode of pharyngitis. Although there was a concern about pulmonary embolism secondary to a lower extremity fracture, his presentation was most consistent with Lemierre syndrome. This syndrome is an uncommon but potentially lethal complication of otolaryngological infections. Early recognition and aggressive antibiotic therapy are critical elements in reducing mortality. Emergency physicians should be aware of this syndrome because its incidence appears to be increasing.
