Your next patient was witnessed to have a tonico-clonic seizure 30 min ago. He remains GCS 6. Why might that be?
Causes of persisting altered mental state following a seizure
– status epilepticus
– iatrogenic (i.e. given benzodiazepines prehospital or in ED)
– normal postictal state
– persisting cause (of seizure + AMS): hypoNa / hypoglycaemia / toxins / SAH / intracerebral haemorrhage / meningitis / encephalitis
– complications of the ictal state – hypoxic brain injury / severe metabolic acidosis
