Acute pulmonary edema (APE) is a common cause of acute dyspnea. In the prehospital setting, it is often difficult to differentiate APE from other causes of shortness of breath (SOB). Radiography and echocardiography aid in the identification of APE but are often not available. There is little information on how accurately ambulance paramedics identify patients with APE. Objectives. This study aimed to 1) describe the prehospital clinical presentation and management of patients with a clinical diagnosis of APE and 2) compare the accuracy of coding of APE by paramedics against the emergency department (ED) medical discharge diagnosis. ⋯ Acute pulmonary edema is difficult to identify in the prehospital setting because of the variability in the signs and symptoms associated with this condition. Improved identification of APE is essential in the initiation of appropriate and timely care. Ambulance paramedics need to be aware of such variability when considering patients who may be suffering from APE. Key words: pulmonary edema; acute pulmonary edema; emergency medical services; ambulance; paramedics.

Prior data from our institution suggested that our paramedics can accurately interpret ST-segment elevation myocardial infarction (STEMI) on prehospital 12-lead electrocardiograms (ECGs), and that activation of the cardiac catheterization laboratory by paramedics immediately upon diagnosing STEMI at the scene could potentially decrease door-to-balloon (D2B) times. A "field activation" protocol was thus initiated in May 2010. This study examined D2B times and compliance with the national 90-minute D2B performance benchmark in the first 14 months. Hypothesis. We hypothesized that D2B times would be shorter, and 90-minute compliance better, when the catheterization laboratory was activated by emergency medical services (EMS), compared with when either EMS failed to activate the catheterization laboratory or when the STEMI patient arrived by means other than EMS. ⋯ In the system studied, EMS field activation of the catheterization laboratory for patients with STEMI is associated with shorter D2B times and better compliance with 90-minute benchmarks than ED activation for either walk-in STEMI patients or STEMI patients arriving by EMS without field activation. Improvements are needed in compliance with the field activation protocol to maximize these benefits. Key words: emergency medical services; emergency medical technicians; electrocardiography; myocardial infarction; heart catheterization.

The use of beta-adrenergic antagonists in acute heart failure is controversial. In this case series, we report the use of intravenous atenolol, a short-acting cardioselective beta-adrenergic antagonist, to treat acute pulmonary edema in the prehospital setting. Four patients with a documented history of cardiac disease and one patient with unknown cardiac issues experienced severe respiratory distress and presented with pulmonary edema; the local emergency medical service was utilized. ⋯ However, only a small increase in oxygen saturation was observed. Intravenous atenolol was administered and led to a dramatic increase in SpO2. In our case series, we observed the positive effect of early treatment with short-acting beta-adrenergic antagonists on the recovery of rapid oxygen delivery in severely hypoxemic patients.

Review
Expanding paramedic scope of practice in the community: a systematic review of the literature.
Paramedics are an important health human resource and are uniquely mobile in most communities across Canada. In the last dozen years, challenges in the delivery of health care have prompted governments from around the globe to consider expanding the role paramedics play in health systems. Utilizing paramedics for the management of urgent, low-acuity illnesses and injuries has been coined "community paramedicine," but the role, safety, and effectiveness of this concept are poorly understood. ⋯ Community paramedicine research to date is lacking, but programs in the United Kingdom, Australia, and Canada are perceived to be promising, and one RCT shows that paramedics can safely practice with an expanded scope and improve system performance and patient outcomes. Further research is required to fully understand how expanding paramedic roles affect patients, communities, and health systems.

Opioid (including prescription opiate) abuse and overdose rates in the United States have surged in the past decade. The dearth and limitations of opioid abuse and overdose surveillance systems impede the development of interventions to address this epidemic. Objective. We explored evidence to support the validity of emergency medical services (EMS) data on naloxone administration as a possible proxy for estimating incidence of opioid overdose. ⋯ While our findings suggest limitations of EMS naloxone administration data as a proxy indicator of opioid overdose, the results provide partial support for using these data for estimating opioid overdose incidence and suggest ways to improve such data. The study findings have implications for an EMS role in conducting real-time surveillance and treatment and prevention of opioid abuse and overdose.
