    • Maintain patent airway with suctioning and/or turning on side.
    • Ensure safety by padding side rails, DO NOT RESTRAIN, and remove or loosen tight clothing.
    • Establish IV access, and anticipate administration of phenobarbital, phenytoin (Dilantin), benzos to control seizures.
    • Assist with ventilation if needed after seizure or intubation if gag reflex is absent.
  29. What are the 2 most commonly used antiseizure drugs during a status epilepticus seizure? What is it usually followed up with?
    • Lorazepam and diazepam are commonly given as a rapid-acting IV.
    • They are short-acting drugs, so it is followed up with a long-acting drug such as phenytoin or phenobarbital.
  30. How can these 3 therapies help with seizures?

    Vagal nerve stimulation
    Ketogenic diet
    Biofeedback
    • Vagal nerve stimulation: surgically implanted electrode in the neck delivers impulses to the vagus nerve is activated with a magnet when a seizure is imminent.
    • Keto diet: may be effective for patients with drug-resistant epilepsy.
    • Biofeedback: aimed to teach patient to maintain certain brain wave frequency that is refrACTORY TO seizure activity
