[Post-traumatic seizure prevention--results of a survey of 127 neurosurgery clinics].

Starting in November, 1993, until January, 1994, we performed a survey among 127 Neurosurgical Departments in Austria, Germany, and Switzerland concerning the practice of antiepileptic prophylaxis in head injured patients. Seventy seven percent of the 12-item multiple choice questionnaires were completed and returned. They indicate a variety of attitudes towards prophylaxis for seizures: in 12% of the responding institutions, antiepileptic prophylaxis is given to every brain trauma patient, in 36%, no prophylaxis is carried out. and in 52% some patients receive prophylaxis while others do not. Penetrating injuries, intracranial haemorrhages and electroencephalographic abnormalities were the most frequent reasons why prophylaxis was initiated. Phenytoin is by far the most popular drug, given usually for at least three months, and in most cases monitored by routine serum level observations. Nevertheless, about three out of four neurosurgeons conceded that a general renunciation of antiepileptic prophylaxis after brain trauma might be justified. There is no uniform way in which patients are informed about a possible risk of seizures, as it may be relevant, for instance, in respect of driving abilities.
