The evaluation of the impact of out-of-hospital emergency care is a relatively new research focus. As such, there is a compelling need to determine how finite health care resources should be used in this setting. The objective of this study is to conduct a structured review of published economic evaluations of out-of-hospital emergency care to assess its economic value. ⋯ There is a paucity of out-of-hospital care literature that addresses cost and economic value. The extant literature is limited in scope, poor in quality, and evaluates small subsets of out-of-hospital emergency care costs. Favorable cost-effectiveness has not been firmly established for most aspects of out-of-hospital emergency care.

Randomized Controlled Trial Comparative Study
Etomidate versus midazolam for out-of-hospital intubation: a prospective, randomized trial.
The primary objective of this study is to compare the intubation success rates of etomidate and midazolam when used for sedative-facilitated intubation, without paralytics, in out-of-hospital adult patients. ⋯ There were no observed differences between midazolam and etomidate in sedation-facilitated intubation success rates; we could not fully evaluate global outcomes of these agents or the sedative-facilitated intubation strategy itself.

Randomized Controlled Trial Comparative Study
Laryngeal view during laryngoscopy: a randomized trial comparing cricoid pressure, backward-upward-rightward pressure, and bimanual laryngoscopy.
External cricoid and thyroid cartilage manipulations are commonly taught to facilitate laryngeal view during intubation. We compare the laryngeal views during laryngoscopy with 4 manipulations (no manipulation, cricoid pressure, backward-upward-rightward pressure [BURP], and bimanual laryngoscopy) to determine the method that optimizes laryngeal view. ⋯ Using a cadaver model, we found pressing on the neck during curved blade laryngoscopy greatly affects laryngeal view. Overall, bimanual laryngoscopy improved the view compared to cricoid pressure, BURP, and no manipulation. Cricoid pressure and BURP frequently worsen laryngoscopy. These data suggest bimanual laryngoscopy should be considered when teaching emergency airway management.

While remaining prominent in paramedic care and beneficial to some patients, out-of-hospital endotracheal intubation has not clearly improved survival or reduced morbidity from critical illness or injury when studied more broadly. Recent studies identify equivocal or unfavorable clinical effects, adverse events and errors, interaction with other important resuscitation interventions, and challenges in providing and maintaining procedural skill. We provide an overview of current data evaluating the overall effectiveness, safety, and feasibility of paramedic out-of-hospital endotracheal intubation. These studies highlight our limited understanding of out-of-hospital endotracheal intubation and the need for new strategies to improve airway support in the out-of-hospital setting.

We determine the rate of adverse effects associated with the use of intravenous (IV) epinephrine by infusion for the treatment of severe asthma in the emergency department (ED). ⋯ IV epinephrine is associated with a low rate of major and a moderate rate of minor adverse events in patients with severe asthma; however, a causal relationship has not been established. Further research investigating effectiveness, as well as safety, is warranted.
