Seizure in rural & remote settings

Template for documenting a seizure:

  • Before (pre-ictal): what was happening at time of onset, any trigger, any aura?

  • During (ictal)

    • Duration (timed vs estimated)

    • Onset (versive head turn, ictal cry, posturing, etc)

    • Eyes (open/closed, deviated)

    • Movements (stiffening / rhythmic; synchronous; distribution (unilateral/bilateral, arms/legs, pelvis/head)

    • Other: tongue biting, incontinence

    • Treatment

  • After (post-ictal): time to baseline, focal deficits.

Choosing to start an anti seizure medication

Typically only start if >60% risk of additional seizure.

  • ≥2 unprovoked seizures. (ie. Substance-induced do not qualify).

  • Seizure + imaging abnormality or EEG abnormality.

  • High-risk features to consider:

    • FHx epilepsy

    • PMHx major head injury

    • Nocturnal seizure

    • Status epilepticus on first presentation*
      *NOTE: this does not clearly indicate higher risk of recurrence!

In remote (± rural) settings, consider a lower threshold to start ASM:

  • Status epilepticus in a remote setting often a life-threatening situation.

  • Shared decision-making with patient.

  • Balance risk of seizure in a low-resource setting vs risks of adverse effects from ASM.

How to choose:

  • www.epipick.org - very helpful guideline especially for patients with comorbidities or specific demographic factors.

  • Consider patient factors:

    • Epilepsy type: focal vs generalized (NEW adult-onset seizures most often focal).

    • Possibility of pregnancy:

      • Best: LTG, LEV

      • Avoid VPA, TPX. Caution with enzyme inducers interaction with hormonal OCP.

    • Obesity: avoid VPA (weight gain)

  • Consider patient comorbidities:

    • Requires DOAC (ex. post-stroke):

      • Best: LEV, LAC, BRV

      • Avoid: inducers CBZ, PHT, PB.

    • Mood / psychiatric history:

      • Best: LTG, LAC, CBZ

      • Avoid: LEV, PER

    • Cardiac conduction abn: caution with any Na+ channel blockers, especially LAC.

  • Med specific:

    • Consider access: older medications may be more accessible. In resource-limited settings, supply issues may contribute to medication interruptions. Discuss with pharmacy prn.

    • Once-daily dosing: cenobamate, ESL, PHT.

    • Coverage: most ASMs can be accessed through EAP or NIHB special access.

    • Levels available: PHT, CBZ, VPA ± LEV (usually send-out / delayed).

Legend:

  • VPA - valproic acid

  • PHT - phenytoin

  • LEV - levetiracetam

  • LAC - lacosamide

  • TPX - topiramate

  • PB - phenobarbital

  • PER - perampanel

  • ESL - eslicarbazepine

Transfer or observe? Seizure checklist and call script

After a seizure stops, the decision that matters most is whether this person needs medical transport, and the acuity (medevac vs “schedevac”).

This is for adults who have had a seizure or status epilepticus and are now in your care at a nursing station, health centre, or small hospital. This assumes you have no CT, no EEG, and a medevac measured in hours.

Transfer if any of the following:

  • Seizures are refractory, or recur despite an appropriately dosed benzodiazepine and antiseizure medication.

  • The patient is not improving within ~60 minutes of the seizure stopping. Non-convulsive status can’t be excluded without EEG.

  • There is a new or worsening focal deficit that is not clearly resolving.

  • The patient takes an anticoagulant, or there is a recent history of head trauma.

  • There is fever, meningism, or immunosuppression.

  • The patient is pregnant or up to 6 weeks postpartum.

  • The airway is a concern, or the patient needed a large sedative dose (benzodiazepine or phenobarbital).

  • You can’t observe them safely: there’s no overnight staff, no one can stay with them, or you’re worried.

Consider local observation when all of the following apply:

  • The patient is back to baseline or clearly improving on serial exams.

  • There is a known cause (known epilepsy diagnosis, clear provoking factor such as substance use).

  • Glucose, Na, and other POCT results are normal or corrected.

  • Someone can observe the patient and call for help, and there is a plan if another seizure occurs.

A new seizure always needs head imaging. CT can wait (ex. standard transport as opposed to medieval) when all the following apply:

  • The patient is back to baseline with a normal neurological examination.

  • No head trauma or anticoagulation.

  • No fever, red-flag headache features (SNOOPPP), no history of immunosuppression.

  • Outpatient imaging and follow-up are booked.

Communicating with Neurology on call:

Have these in front of you. You don’t need a full neurological exam; the neurologist will walk you through what matters.

  • Times: when the patient was last seen well, when the seizure started, and when each seizure stopped.

  • What was seen: which side started, any eye or head turning, whether the eyes were open or closed, and how long it lasted. Ask whether anyone has phone video.

  • Every drug given: name, dose, route and time, including anything EMS or family gave.

  • Usual medications: antiseizure drugs with doses and adherence, and any anticoagulant.

  • Now: GCS, pupils, which limbs move, speech, and vital signs.

  • Results: glucose, sodium and any other point-of-care tests.

  • Logistics: realistic medevac arrival time, and what your site can and can’t do (intubation, infusions, overnight staff).

  • Your question: advice only, or transfer.

S — Situation: who you are, where you are, and your question.
B — Background: seizure history, usual antiseizure medications and adherence, anticoagulants, and other key history.
A — Assessment: timeline, what you saw, every drug with dose and time, current exam, and results.
R — Request: what you need, and your constraints.
Always with a readback.
