From the Guidelines

The treatment for post-assault seizures should prioritize immediate stabilization and anticonvulsant therapy, with benzodiazepines as the first-line treatment, followed by antiepileptic drugs such as levetiracetam or valproate, as recommended by the most recent guidelines 1. When managing post-assault seizures, it is crucial to ensure the patient's airway is clear and they are in a safe position to prevent injury.

  • The first-line treatment for acute seizures involves administering benzodiazepines, such as lorazepam (2-4 mg IV) or diazepam (5-10 mg IV), to stop ongoing seizure activity 1.
  • If seizures persist, a second dose may be given after 5-10 minutes.
  • For longer-term management, antiepileptic drugs such as levetiracetam (500-1000 mg twice daily) or valproic acid (loading dose of 20-40 mg/kg, then 500-1000 mg twice daily) may be prescribed, as they have been shown to be effective in suppressing epileptiform activity in the EEG 1.
  • The choice of antiepileptic drug depends on the patient's medical history and seizure characteristics.
  • Neuroimaging (CT or MRI) is essential to identify traumatic brain injuries that may be causing the seizures.
  • Blood tests should be performed to check for metabolic abnormalities, toxins, or infections that could trigger seizures.
  • Close follow-up with a neurologist is important to adjust medication and monitor recovery. It is also important to note that the treatment of post-assault seizures should be individualized, taking into account the patient's specific needs and circumstances, and that the use of sedating agents may delay awakening 1.

From the FDA Drug Label

In adults, a loading dose of 10 to 15 mg/kg should be administered slowly intravenously, at a rate not exceeding 50 mg per minute (this will require approximately 20 minutes in a 70-kg patient). The loading dose should be followed by maintenance doses of 100 mg orally or intravenously every 6 to 8 hours If administration of parenteral Phenytoin Sodium Injection does not terminate seizures, the use of other anticonvulsants, intravenous barbiturates, general anesthesia, and other appropriate measures should be considered.

The treatment for post-assault seizure involves administering a loading dose of 10 to 15 mg/kg of phenytoin intravenously, followed by maintenance doses of 100 mg every 6 to 8 hours. If the seizures do not terminate with phenytoin, other measures such as intravenous barbiturates or general anesthesia may be necessary 2.

Treatment for Post-Assault Seizure

The treatment for post-assault seizure is crucial and requires immediate attention.

  • The first line of treatment for drug-induced seizures, which can be a result of assault, involves the use of benzodiazepines 3.
  • Benzodiazepines, such as lorazepam, are effective in controlling seizures and are recommended as the first line of treatment 4, 5.
  • If benzodiazepines fail to halt seizures promptly, second-line drugs such as barbiturates and propofol may be used 3.
  • In cases where isoniazid poisoning is a possibility, pyridoxine is given 3.
  • Levetiracetam is also a promising option for the treatment of status epilepticus, although its role is not yet fully established 3, 4.
  • Lorazepam has been shown to be as efficacious and safe as diazepam-phenytoin combination in the treatment of convulsive status epilepticus in children 6.
  • Prehospital treatment of status epilepticus with benzodiazepines is effective and safe, and treatment should be initiated when seizures have lasted 5-7 minutes 5.
  • Lorazepam has also been used for the prevention of recurrent seizures related to alcohol, and has been shown to be effective in reducing the risk of recurrent seizures 7.
