seizure prophylaxis
Pronunciation: pro-fi-LAK-sis
Preventive antiepileptic medication administration to reduce seizure risk in neurosurgical patients.
Full Definition
Seizure prophylaxis involves the administration of antiepileptic drugs (AEDs) to prevent seizures in patients at risk, particularly those undergoing neurosurgical procedures or with brain tumors. Prophylactic AEDs are commonly used perioperatively in supratentorial surgeries, especially those involving cortical incisions or tumor resections. The duration and choice of prophylactic medication varies by institution and patient factors. Evidence suggests limited benefit for routine prophylaxis in all neurosurgical patients, but it remains standard practice for high-risk procedures and patients with brain tumors.
Usage
Usage note: Specify medication, dose, and duration; distinguish from therapeutic seizure treatment.
