Sincope neuromediata e infortuni sul lavoro: strategie preventivee considerazioni su un caso clinico

A bus driver came to our observation after an occupational traffic accident due to a syncopal event. The positive result of the tilt testing demonstrated the neurally-mediated nature of the syncope. The accident involved approximately 40 people (all the bus passengers), fortunately without severe injuries or deaths. The described episode indicates the need for a procedural algorithm, commonly approved, applicable in the field of prevention, for those occupational categories with severe accident risk. Indeed, the possibility exists to identify at least a part of the subjects predisposed to neurally-mediated syncope. Fundamental steps for such screening are history taking (looking for previous events, familiarity), the physical examination (useful, for example, to exclude orthostatic hypotension or carotid sinus syncope), and, in particular, the tilt testing, a diagnostic investigation reccomended for all the workers who have had a previous syncope and are at high occupational accident risk. Moreover, the reported case recalls the need to strengthen the collaboration between the cardiologist and the occupational health physician.
