This clinical study prospectively evaluated the first-shock defibrillation efficacy of 150-joule impedance-compensated, 200-microF biphasic truncated exponential (BTE) shocks in patients with electrically-induced ventricular fibrillation (VF), and compared it with a historical control group treated with 200-J monophasic damped sine (MDS) shocks. ⋯ This study demonstrated that 150-J shocks of this impedance-compensated, 200-microF BTE waveform provided very high efficacy for defibrillation of short duration, electrically-induced VF. These lower-energy biphasic shocks had a success rate equivalent to that of 200-J MDS shocks, and they provided this efficacy while exposing patients to much less current than the monophasic shocks.

This study evaluated the feasibility of using the emergency medical services (EMS) system as a public health provider by having paramedics screen older adults (age >or= 65 years) for influenza immunization status during emergency responses. It also determined the proportion of older-adult EMS patients who lacked an influenza vaccination. ⋯ Paramedics can screen a majority of older adults for influenza immunization status during emergency responses. Older adult users of EMS reported lacking influenza vaccination at levels similar to national estimates. An EMS-based, paramedic-implemented screening program has the potential to identify older adults at risk for preventable illnesses and to augment traditional screening programs, but additional measures are needed to enhance screening rates.

The Brain Trauma Foundation (BTF) Guidelines for Prehospital Management of Traumatic Brain Injury (TBI) are intended to standardize treatment and improve outcomes in severe TBI patients. The key guideline components focus on airway management, blood pressure support, Glasgow Coma Score assessment, and transport. The purposes of this study were to determine if providers could learn and retain the guidelines (education), assess if providers would use the guidelines in practice (implementation), and evaluate the effect of guideline implementation on patients (outcomes). ⋯ Providers were able to learn and implement the BTF guidelines, and outcomes in TBI patients were significantly improved. All emergency medical services providers should be trained in these potentially lifesaving guidelines.

To develop a mathematical formula that assists in determining the number of automated external defibrillators (AEDs) needed at sites of mass gatherings. ⋯ Given a medical director's targeted response times and goals, the optimal number of AEDs required at a mass gathering can be calculated using time versus distance relationships. Future studies should evaluate the impact of the mathematically derived optimal number of AEDs at mass gatherings.

This study compares etomidate with midazolam for prehospital rapid-sequence intubation (RSI). ⋯ Intubation success rate was very high with both etomidate (98%) and midazolam (99%). There was no statistically significant mean percentage of change in SBP or HR with either agent. The authors found a low incidence of hypotension with both agents, although the mean dose of midazolam used was considerably less than typically recommended for induction.
