Comparison of Droperidol and Haloperidol for Use by Paramedics: Assessment of Safety and Effectiveness.
Since the 2001 "black box" warning on droperidol, its use in the prehospital setting has decreased substantially in favor of haloperidol. There are no studies comparing the prehospital use of either drug. The goal of this study was to compare QTc prolongation, adverse events, and effectiveness of droperidol and haloperidol among a cohort of agitated patients in the prehospital setting. ⋯ In this cohort of agitated patients treated with haloperidol or droperidol in the prehospital setting, there was no significant difference found in QTc prolongation, adverse events, or need for repeat sedation between haloperidol and droperidol.

Seizure is a frequent reason for activating the Emergency Medical System (EMS). Little is known about the frequency of seizure caused by hypoglycemia, yet many EMS protocols require glucose testing prior to treatment. We hypothesized that hypoglycemia is rare among EMS seizure patients and glucose testing results in delayed administration of benzodiazepines. ⋯ Rates of hypoglycemia were very low in patients treated by EMS for seizure. Glucose testing prior to benzodiazepine administration significantly increased the median time to benzodiazepine administration. Given the importance of rapid treatment of seizure in actively seizing patients, measurement of blood glucose prior to treating a seizure with a benzodiazepine is not supported by our study. EMS seizure protocols should be revisited.

Pepper Spray Injury Severity: Ten-year Case Experience of a Poison Control System.
Pepper spray is a common lacrimator used by law enforcement and the public to subdue individuals and for self-defense. The risk factors for severe injury due to pepper spray exposure are not well documented and there is a lack of guidelines to identify patients that require transport and medical evaluation in an emergency department. ⋯ There was a low 1 in 15 potential risk for more severe adverse health effects in persons exposed to pepper spray that warranted a medical evaluation. The risk was highest when used for training of law enforcement personnel and involved severe ocular symptoms. This suggests that routine use of pepper spray for training of law enforcement or military personnel be reconsidered. Protective goggles may be an option when direct spraying into the face of trainees. Transport for medical evaluation should be considered for exposed persons that manifest persistent ocular or respiratory symptoms.

To determine whether emergency physicians (EPs) and prehospital emergency medical services (EMS) personnel differ in their assessment of motor vehicle crash (MVC) severity and the potential for serious injury when viewing crash scene photographs. ⋯ Although overall agreement between EPs and EMS personnel was excellent, differences in estimation of crash severity and potential for injury were identified among crashes estimated to be moderate in severity.

Comparative Study
Comparison of Video, Optical, and Direct Laryngoscopy by Experienced Tactical Paramedics.
While optical and video laryngoscopy have been studied in the emergency department, the operating room, and the routine prehospital setting, their efficacy in the tactical environment--in which operator safety is as important as intubation success--has not been evaluated. This study compared direct laryngoscopes to optical (AirTraq) and video (King Vision) laryngoscopes in a simulated tactical setting. ⋯ Video and optical laryngoscopes can be used successfully by experienced tactical paramedics in a simulated tactical setting. The King Vision and AirTraq resulted in improved Cormack-Lehane glottic views but similar times to ventilation and first-pass success compared to direct laryngoscopy. Intubator head height was lower with direct laryngoscopy. Clarifying the role of optical and video laryngoscopes in a tactical environment, especially in the hands of less experienced intubators, requires further research.
