摘要
Objective： To analyze the injuries of motorcyclists involved in fatal motorcycle frontal crashes. Methods： A survey group involving multi-discipline experts was built to randomly collect data on fatal motor- cycle frontal collision accidents that occurred in Chongqing during 2006-2010. The sampled information included medi- cal or autopsy reports, blood alcohol concentration （BAC） level, helmet use, accident witness, field sketch as well as field photos. The motorcyclist injuries were scored accord- ing to the Abbreviated Injury Scale （AIS） 2005. The involved riders with a BAC level^20 mg/ml were attributed to alco- hol use. Data were processed statistically with nonparamet- tic test via software SPSS 11.0. Results： A total of 86 fatal motorcycle frontal crashes were sampled and further analyzed. The age of motorcy- clists enrolled in this investigation showed nominal distri- bution and the middle-aged （30-39 years） occupied the high- est percentage of fatalities. There were only 14 motorcyclists （16.3%） wearing helmets at the moment of collision. And 12.8% of these motorcyclist crashes were attributable to alcohol use. Impact injury was the main fatal cause, accounting for 72% of motorcyclist deaths, followed by tumbling injury （26%） and run-over （2%）. Respectively 84%, 22% and 19% of motorcyclists who sustained head, chest and abdominal trauma died. Extremity injury was the most trequently observed injury type. Conclusions： This investigation is helpful to build accident prevention programs and develop protection devices which may effectively mitigate injuries and prevent deaths following motorcycle frontal collision accidents. Further investigations on motorcycle collision accidents are still needed.
