Management of Combative Behavior in Post-Craniotomy Patients

Assessment and Evaluation

The American Academy of Emergency Medicine recommends considering switching to valproate (30 mg/kg IV) for seizure control in patients with combative behavior, as it has demonstrated similar efficacy to levetiracetam with potentially fewer psychiatric side effects 1
Post-craniotomy patients with subdural hematoma are at risk for encephalopathy, which may be exacerbated by medication side effects, underlying neurological injury, or undetected seizure activity 2, 3

The American Academy of Neurology recommends valproate as a first-line treatment option for seizure control in post-craniotomy patients, with a recommended loading dose of 30 mg/kg IV infused at 5-6 mg/kg per hour 3, 6
The American College of Emergency Physicians suggests considering lamotrigine as an alternative option for antiseizure medication, due to its favorable psychiatric side effect profile 1
The American Heart Association recommends avoiding phenytoin/fosphenytoin in patients with intracranial hemorrhage due to associated excess morbidity and mortality 7, 8

The Society of Critical Care Medicine recommends propofol as a sedation option for severe agitation requiring immediate intervention, with a suggested dose of 2 mg/kg bolus followed by 3-4 mg/kg/hr infusion 2, 7
The American Academy of Neurology suggests continuous EEG monitoring to detect subclinical seizures, especially in high-risk patients 8

The American Association of Neurological Surgeons recommends regular assessment of serum drug levels to ensure therapeutic range and evaluate for toxicity 1
The Neurocritical Care Society suggests monitoring for improvement in mental status and behavior after medication adjustment 1
The American Stroke Association recommends avoiding the use of phenytoin for seizure prophylaxis in patients with intracranial hemorrhage due to associated excess morbidity 8
