Case Reports
Field airway management of a construction worker with an impaling rebar injury to the neck and brain.
This article discusses a case of airway management by air ambulance emergency medical services (EMS) providers in a 22-year-old man impaled through the neck into the brain with 0.5-inch rebar. Penetrating neck injuries (PNIs) with impalement are extraordinarily rare. It is important for EMS providers and emergency medicine physicians to have an understanding of the initial management of an impaled patient with PNI, including having an organized approach to establishing a definitive airway and recognizing the airway complications that PNI may cause. This article discusses out-of-hospital management of impaled patients.

Case Reports
Potential utility of near-infrared spectroscopy in out-of-hospital cardiac arrest: an illustrative case series.
We evaluated the measurement of tissue oxygen content (StO(2)) by continuous near-infrared spectroscopy (NIRS) during and following cardiopulmonary resuscitation (CPR) and compared the changes in StO(2) and end-tidal carbon dioxide (ETCO(2)) as a measure of return of spontaneous circulation (ROSC) or rearrest. ⋯ This preliminary study in humans demonstrates that StO(2) dynamically changes during periods of hemodynamic instability in postarrest patients. These data suggest that a decline in StO(2) level may correlate with rearrest and may be useful as a tool to predict rearrest in post-cardiac arrest patients. A rapid increase in StO(2) was also seen upon ROSC and may be a better method of identifying ROSC during CPR than pauses for pulse checks or ETCO(2) monitoring.

Comparative Study
Ondansetron oral dissolving tablets are superior to normal saline alone for prehospital nausea.
Antiemetics have been shown to be effective in multiple hospital settings, but few studies have been done in the prehospital environment. ⋯ There was no improvement in patient nausea related to quantity of saline alone during an EMS transport. The addition of ondansetron ODT resulted in a significant improvement in degree of nausea.

This paper describes the methodology of a large emergency medical services (EMS) data linkage research project currently under way in the statewide EMS system of New South Wales, Australia. The paper is intended to provide the reader with an understanding of how linkage techniques can be used to facilitate EMS research. This project, the Australian Prehospital Outcomes Study of Longitudinal Epidemiology (APOStLE) Project, links data from six statewide sources (computer-assisted dispatch, EMS patient health care reports, emergency department data, inpatient data, and two death registries) to enable researchers to examine the patient's entire journey through the health care system, from the emergency 0-0-0 call to the emergency department and inpatient setting, through to discharge or death, for approximately 2.6 million patients transported by the Ambulance Service of New South Wales to emergency departments between June 2006 and July 2009. Manual, deterministic, and probabilistic data linkages are described, and potential applications of linked data in EMS research are outlined.
