Comparative Study
Comparison of emergency medical services systems across Pan-Asian countries: a Web-based survey.
There are great variations in out-of-hospital cardiac arrest (OHCA) survival outcomes among different countries and different emergency medical services (EMS) systems. The impact of different systems and their contribution to enhanced survival are poorly understood. This paper compares the EMS systems of several Asian sites making up the Pan-Asian Resuscitation Outcomes Study (PAROS) network. Some preliminary cardiac arrest outcomes are also reported. ⋯ We found substantial variation in 11 communities across the PAROS EMS systems. This study will provide the foundation for understanding subsequent studies arising from the PAROS effort.

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.

Urban trauma systems are characterized by high population density, availability of trauma centers, and acceptable road transport times (within 30 minutes). In such systems, patients meeting field trauma triage (FTT) criteria should be transported directly to a trauma center, bypassing closer non-trauma centers. ⋯ Differential distance between the closest non-trauma center and the closest trauma center was associated with lower compliance with triage protocols, even in an urban setting where trauma centers can be accessed within approximately 30 minutes. Our findings suggest that there are opportunities for reducing the gap between ideal and actual application of field trauma triage guidelines through a process of education and feedback.

Intoxication, whether from alcohol, drugs, or alcohol and drugs in combination, remains a challenging burden on emergency departments. The increasing alcohol consumption among adolescents and young adults, particularly heavy episodic drinking, and the resulting increase in the use of health care resources for alcohol intoxication has been a widely discussed topic. ⋯ Our findings suggest two main vulnerable groups: young persons under 25 years of age, with a particular focus on women, having the greatest increase over time, and middle-aged men, having the greatest proportion among all cases observed. Intervention efforts should include a high-risk approach to reduce alcohol-related problems. Key words: alcohol intoxication; substance-related disorders; aggression; injuries; emergency medical services.
