Six minutes pass. The patient's right arm continues to rhythmically jerk. He asks you if you can stop it, because it's getting annoying. You're a bit more worried than he is, because this seems to be focal status epilepticus.
Yes, it's not great to see that the patient is in status epilepticus. However, one of the important qualifiers here is that he is in focal motor status epilepticus. Not all focal status is created equally. The second key additional piece of information you really need to know to craft an appropriate plan is the patient's current mental status.
If the patient's mentation is totally preserved and he's just talking to you as his arm is convulsing away, great. This patient here has focal motor status epilepticus with preserved awareness, which is also known as epilepsia partialis continua (EPC). EPC can be notoriously difficult to treat, and will actually end up being fine so long as you don't overdo it with sedating medications; you don't want to give him a reason to get intubated. Of course, you should ensure that the patient is very carefully monitored in this acute phase, as his mentation may very well decline, which would then necessitate more aggressive management.
If the patient's mentation is clearly acutely impaired in association with this focal status, then we should treat this as we would any other typical generalized convulsive status epilepticus, going through the usual algorithm with first-line benzodiazepines followed by levetiracetam vs. fosphenytoin vs. valproic acid followed by intubation and propofol.
Unfortunately, there are times when the patient's mentation is stably poor throughout the admission, and it's not clear whether it's been further impaired by the focal status. It can be helpful to contextualize this development in terms of the patient's current and overall clinical course, their baseline neurologic status, their ongoing comorbidities and how they'd affect and be affected by status management, and their goals of care. It's common in these situations to have to err on the side of initial aggressive management (treated as we would with generalized convulsive status), and then using their response in the coming days to guide continued management, whether it's high doses of sedatives or continued multi-ASM uptitration.
For this patient, because his mentation is reassuring but this has been going on for six minutes, you ask the ED to order IV lorazepam 2mg.
