We evaluated the benefit of emergency medical services providers' placing a second intravenous (IV) line in the prehospital trauma setting. Our hypothesis was that the placement of a second IV catheter in trauma does not result in an improvement in heart rate, blood pressure, rehospitalizaton rate, or 30-day mortality. ⋯ Redundant prehospital IV lines provided no noticeable benefit in physiologic support for trauma patients. When controlling for confounding variables, no significant outcome difference was noted, even in the hypotensive patients. The traditional approach for establishment of a secondary IV line in prehospital trauma patients should not be followed in a dogmatic fashion.

Older injured persons are frequently undertriaged, increasing the risk for preventable mortality and morbidity in an already-vulnerable population. Changes made in 2006 to the American College of Surgeons Committee on Trauma (ACS-COT) Field Triage Decision Scheme might improve triage accuracy for this population. ⋯ There is a positive trend in triage accuracy for older injured persons since 2004. Ongoing funding, continued trauma system development with more training emphasis on scene evaluation of older adults, and the use of the ACS-COT triage decision scheme are essential for further improvement of triage accuracy. More research is needed to identify and validate additional triage criteria that are sensitive to severe injuries in older persons.

Comparative Study
Advanced rescuer- versus citizen-witnessed cardiac arrest: Is there a difference in outcome?
Substantial financial and human resources are invested in training and maintaining advanced life support (ALS) skills of paramedics who are deployed to the field in response to out-of-hospital cardiac arrest. It would be expected that patients who experience cardiac arrest in the presence of a trained health care practitioner, such as a paramedic, have better outcomes. ⋯ Among our study population of out-of-hospital cardiac arrest victims, paramedic-witnessed arrests did not appear to have improved survival rates when compared with citizen-witnessed arrests.

To determine how often out-of-hospital cardiac arrest (OHCA) patients who achieve return of spontaneous circulation (ROSC) experience rearrest during their emergency medical services (EMS) care and to analyze their arrest characteristics, including survival to hospital discharge. ⋯ A significant number of OHCA patients who achieved field ROSC experienced rearrest prior to hospital arrival. Patients who experienced rearrest were less likely to survive.

OBJCTIVE: The objectives were to evaluate the safety and efficacy of ondansetron in the out-of-hospital treatment of undifferentiated nausea or vomiting. ⋯ Ondansetron is safe and effective for out-of-hospital treatment of nausea and vomiting when administered by paramedics via the IV, IM, or oral route. When available to paramedics, ondansetron is used frequently.
