Abstract
Seizures may occur in up to 22% of ICU patients with severe traumatic brain injury. There is a relatively high risk of nonconvulsive seizures in this population. Seizures may exacerbate the injury process and disrupt both patient care and family coping. Therefore, seizures should be recognized quickly and treated promptly. The clinician should have a high index of suspicion for seizures, especially in patients with clearly defined risk factors for seizure development. Continuous EEG monitoring should be considered in those patients who are considered to be at high risk of clinical or subclinical seizures. Seizure prophylaxis with antiepileptics is supported by the literature for the prevention of early seizures (defined as < 7 days post-injury) but not for late seizures. Phenytoin and carbamazepine have been used in this setting, and both have been found to be efficacious in preventing early seizures. Phenytoin has several features that make it the best first line agent. Anticonvulsants have not been found to reduce the incidence of developing late posttraumatic seizures and therefore, prolonged prophylaxis with antiepileptics is not currently supported.
