Droperidol is a butyrophenone that has recently been reintroduced after a United States Food and Drug Administration (US FDA) black box warning in 2001. Evidence demonstrates utility in a variety of clinical conditions. ⋯ Current evidence suggests that droperidol is a safe and effective medication for treating nausea and vomiting, headache, vertigo, and agitation in the ED setting.

As foreign body airway obstruction (FBAO) can be life-threatening, it has to be promptly diagnosed and treated. We report a case series of three patients presenting to the emergency department with cardiac arrest due to FBAO. In each case, ventilation was difficult due to high airway resistance. ⋯ The life-saving benefits of bronchoscopy outweigh the small risks of complications such as bleeding, desaturation and pneumothorax. In the three cases, the removal of the obstructing material led to immediate improvements in oxygenation and ventilation. The patients had return of spontaneous circulation after cardiopulmonary resuscitation and definite airway control.

Triptans are potent serotoninergic vasoconstrictors. They are generally avoided in elderly patients age greater than 65 or in patients with a history of CAD. Although there are reported cases of Acute Coronary Syndrome (ACS) or Transient Global Amnesia (TGA) in patients after ingesting therapeutic doses of triptan or dihydroergotamine, this is the first case report, up to our knowledge, of a patient, who had no previous cardiac history, that was diagnosed with both ACS and TGA. ⋯ There is an increasing number of reports delineating sumatriptan's adverse effects. Emergency medicine physicians should promptly recognize the toxic effects and adverse reactions from triptans. Sumatriptan-induced vasoconstriction may lead to cardiac and cerebral ischemic events.

Spinal epidural abscess (SEA) is a rare but serious condition that carries with it a high rate of morbidity and mortality. ⋯ An understanding of SEA can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Randomized Controlled Trial
Advances in clinical trials methodology: Intervention optimization approaches in emergency medicine.
The classical two-arm randomized clinical trial (RCT) is designed to test the efficacy or effectiveness of an intervention, which may consist of one or more components. However, this approach does not enable the investigator to obtain information that is important in intervention development, such as which individual components of the intervention are efficacious, which are not and possibly should be removed, and whether any components interact. The Multiphase Optimization Strategy (MOST) is a new framework for development, optimization, and evaluation of interventions. ⋯ If a fixed intervention, i.e. one in which the same intervention content and intensity is provided to all participants, is to be optimized, a factorial experiment is often appropriate. If an adaptive intervention, i.e. one in which intervention content or intensity is varied in a principled manner, is to be optimized, a sequential multiple-assignment randomized trial (SMART) is often a good choice. The objective of this article is to describe MOST and the scientific rationale for its use; describe two current applications of MOST in emergency medicine research, one using a factorial experiment and the other using a SMART; and discuss funding strategies and potential future applications in studying the care of individuals with acute illness, injury, or behavioral disorders.
