[Motor vehicle accidents with entrapment. A medical and technical investigation of crash mechanism, injury pattern and severity of entrapment of motor vehicle occupants between 1983 and 2003].

Abstract

AIM

Crash mechanisms, injury patterns, and severity of injury of entrapped motor vehicle occupants were analysed by the Accident Research Unit's scientific teams between 1983 and 2003.

RESULTS

Of the 1281 vehicle passenger entrapments in our study, 18.3% happened on highways, 25.6% on federal roads, 35.9% on country roads, and 18.3% on city roads. Of those involved, 69.9% were drivers, 19.4% were front passengers, and 8.5% were rear passengers. Coinvolved objects in car collisions were: other cars 30.9%, trucks 50.2%, objects 18.6%, and motorbikes 0.3%. Coinvolved objects in truck collisions were: other trucks 61.8% and objects 38.2%. The mean Delta-V was 42 km/h (cars 46.2, trucks 32.2). Maximum AIS levels were 31% I, 25.2% II, 19.4% III, 7.8% IV, 7.8% V, and 8.6% VI. Of injuries, 68.7% were to the head, 23.5% to the neck, 50.8% to the chest, 43.6% to upper extremities, 15.4% to the abdomen, 16.4% to the pelvis, and 52.9% to lower extremities. The incidence of multiple injuries (ISS>16) was 23.7%, and mortality was 15.9%.

CONCLUSION

Car drivers are more at risk of accidents with entrapment on rural streets, and truck drivers are more at risk on highways. In most cases car occupants crash with trucks or other cars, and truck drivers collide more frequently with other trucks or objects. Besides a high degree of severe single injuries, there is also a high incidence of multiple injury victims and high mortality. Of the fatalities, 74.5% occur during the preclinical course and 24.5% during the clinical course.
