[Secondarily accelerated foreign bodies as a source of danger from airbag deployment].

BACKGROUND

The use of airbag systems in motor vehicle construction has led to a significant reduction in both the frequency and intensity of injuries during traffic accidents. However, recent reports have shown numerous cases in which it is assumed that the airbag was the major cause of serious injury.

CASE REPORT

In a collision with a wild boar, both airbags in the automobile deployed. The driver suffered facial abrasion and belt contusion to the left shoulder. The passenger held a glass bottle in her hands during the impact that, secondarily accelerated through the airbag, hit both eyes and the bridge of her nose. On clinical admission, the patient showed fractures of the nasal bridge, of both medial orbital walls on both sides and a massive periocular haematoma which required direct examination under narcosis. Both eyes showed an orbital contusion, a large area of corneal abrasion, traumatic mydriasis with sphincter tears such as bilateral 90% hyphema. During surveillance, a progressive reduction in visual acuity occurred. After posterior chamber vitrectomy with epiretinal peeling and posterior chamber lens implantation in the left eye, visual acuity was 0.05 in the left eye and 0.01 in the right.

CONCLUSIONS

A considerable danger emanates from objects which are situated between head and airbag in the moment of airbag deployment. This requires public education and, in addition, airbag systems which are adapted to the drivers height and weight, as well as to objects in its immediate vicinity.
