Randomized Controlled Trial
Physiological recovery from firefighting activities in rehabilitation and beyond.
The primary objective of this study was to document the timeline of physiologic recovery from firefighting activities in order to inform emergency medical services (EMS) of vital sign values that might be expected during incident rehabilitation and in developing rehabilitation protocols to make decisions about when to return personnel to the fireground. Secondarily, we compared two different incident rehabilitation strategies to determine effectiveness in reducing physiologic strain following firefighting. ⋯ The timeline for recovery from firefighting activities is significantly longer than the typical 10-20-minute rehabilitation period that often is provided on the fireground. Modifications from the current rehabilitation protocol do not appear to improve the recovery timeline when rehabilitation is conducted in a cool room. While firefighters often are concerned about elevated blood pressures, this study suggests that firefighters and EMS personnel should also be cognizant of the potential dangers of hypotension.

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.

Randomized Controlled Trial Comparative Study
A comparison of cooling techniques in firefighters after a live burn evolution.
We compared the use of two active cooling devices with passive cooling in a moderate-temperature (≈ 22 °C) environment on heart rate (HR) and core temperature (T(c)) recovery when applied to firefighters following 20 minutes of fire suppression. ⋯ During 30 minutes of recovery following a 20-minute bout of fire suppression in a training academy setting, there is a slightly higher cooling rate for FI and no apparent benefit to CV when compared with P cooling in a moderate temperature environment.

Comparative Study
Effectiveness of prehospital morphine, fentanyl, and methoxyflurane in pediatric patients.
To compare the effectiveness of intravenous morphine, intranasal (IN) fentanyl, and inhaled methoxyflurane for managing moderate to severe pain in pediatric patients in the out-of-hospital setting. ⋯ Intranasal fentanyl and intravenous morphine are equally effective analgesic agents in pediatric patients with moderate to severe acute pain in the out-of-hospital setting. Methoxyflurane is less effective in comparison with both morphine and fentanyl, but is an effective analgesic in the majority of children.

The National Association of EMS Physicians (NAEMSP), the American College of Emergency Physicians (ACEP), the Air Medical Physician Association (AMPA), the Association of Air Medical Services (AAMS), and the National Association of State EMS Officials (NASEMSO) believe that patient care and outcomes are optimized by using air medical transport services that are licensed air ambulance providers with robust physician medical director oversight and ongoing quality assessment and review. Only air ambulance medical transport services with these credentials should advertise/market themselves as air ambulance services.
