Multicenter Study Observational Study
Assessment of Emergency Airway Management Techniques in Korea Using an Online Registration System: A Multicenter Study.
The investigators developed a Web-based online registration system to identify the current status of trauma airway management. ⋯ Emergency physicians in Korea are prepared for trauma patient airway management. The backup by experienced senior physicians, and preparation and training for video laryngoscope could assist FPS for trauma patients.

Randomized Controlled Trial
Death Before Disco: The Effectiveness of a Musical Metronome in Layperson Cardiopulmonary Resuscitation Training.
A novel musical memory aid has been proposed for aiding laypersons in complying with the American Heart Association (AHA) cardiopulmonary resuscitation (CPR) guidelines of 100 compressions per minute (cpm). ⋯ Subjects trained to use a musical metronome more often maintained a compression rate of 100-120 cpm at ≥6-week follow-up, suggesting the memory aid may improve long-term guideline adherence.

Falls in the elderly cause serious injury. ⋯ Perceived and actual fall risks are highly associated. Most participants are willing to discuss their fall risk and a home safety evaluation. HF subjects were most willing to have these discussions; ED subjects were less willing than HF, but not significantly different from health fair participants. FP participants were significantly less willing to have these discussions than HF participants. This may suggest a meaningful opportunity for fall risk prevention in outpatient settings such as health fairs and the ED.

Laryngospasm is a rare cause of stridor in adults, and laryngospasm due to hypocalcemia is an unusual finding. ⋯ We present a case of an adult woman with acute dyspnea. A week prior to presentation, she experienced short episodes of a pinching feeling in her throat and difficulty breathing. On primary assessment, stridor and a positive Trousseau sign were noted. Laboratory examination showed hypocalcemia. We concluded that the dyspnea was caused by laryngospasm due to hypocalcemia. Hypocalcemia was treated promptly, and stridor and dyspnea resolved rapidly. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Laryngospasm is a rare, but serious and potentially lethal, complication of hypocalcemia in adults. In every adult presenting with acute dyspnea and stridor, the possibility of hypocalcemia should be considered. Hypocalcemia should be treated promptly.
