Comparative StudyA comparison of emergency medical helicopter accident rates in the United States and the Federal Republic of Germany.
The purpose of this study was to compare accident rates of helicopter emergency medical services (USA-HEMS) to domestic air taxi service (USA-Taxi) and helicopter emergency medical services in the Federal Republic of Germany (FRG-HEMS). Contingency tables compared the total hours flown to the number of fatal and non-fatal accidents for USA-HEMS (1982-7) vs. USA-Taxi (1980-5) and USA-HEMS (1982-7) vs. ⋯ This was significantly different from the USA-Taxi overall accident rate of 6.7/100,000 h and the fatal accident rate of 1.6/100,000 h (chi 2 = 20.441, p = 0.0001). The USA-HEMS overall and fatal accident rates were not significantly different than the FRG-HEMS overall (10.9/100,000 h) and fatal (4.1/100,000 h) accident rate (chi 2 = 0.061, p = 0.97). These data suggest that emergency air transport is inherently more risky than routine air taxi services.

The optimal extent of prehospital care, including intravenous (IV) therapy for critically ill patients, remains unclear. The authors evaluated the success rate for IV cannulation in a moving ambulance by trained emergency medical technicians and paramedics in 641 adult medical- and trauma-related cases. ⋯ In hypotensive patients, the success rates for at least one IV in medical and trauma patients were 80% and 95%, respectively. These data suggest that IV lines can be secured with a high degree of success en route to the hospital by trained personnel, and that prompt transport of unstable patients should not be delayed solely to obtain IV access.
