Objective #2
Wait, can you review seizure classifications
real quick?
![Page 11: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/11.jpg)
Seizure ClassificationGeneralized Partial
Complex Simple Both hemispheres involved
+LOC
Types:- Tonic/clonic- Absence - Atonic (drop attacks)- Infantile spasms
Impaired consciousness
Motor/autonomic sx
May generalize
Types of symptoms: 1) Motor- head/eye deviation, jerking, stiffening2) Autonomic- pupil dilation, drooling, pallor, HR/RR changes3) Somatosensory- smells, alteration of perception
No impaired consciousness
Can involve motor, autonomic, somatosensory
May generalize

Objective #3
This kid’s seizures are not stopping. I’m freaking out.
![Page 14: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/14.jpg)
Status Epilepticus
Life Threatening Emergency
Seizures that persist without interruption > 5 mins
Two or more sequential seizures without full recovery of consciousness between seizures
Millikan D et al. Emerg Med Clin North Am. 2009
![Page 15: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/15.jpg)
Status Epilepticus
Occurs in kids with epilepsy 9-27% over time
Rapid termination of seizure activity protects against neuronal injury
Millikan D et al. Emerg Med Clin North Am. 2009
![Page 16: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/16.jpg)
Riviello JJ et al. Neurology. 2006
Status Epilepticus:Types, Incidence, & Description
![Page 17: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/17.jpg)
Prehospital Assessment
Assess ABCs +D x 2 (Dextrose, Disability)
Positioning (C-spine protection if trauma):Jaw thrust/head tilt chin lift
Recovery position
Nasal airway, if needed and available
Aspiration precautions
Oxygen, Suction
![Page 18: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/18.jpg)

Prehospital Assessment
Obtain seizure history
How long was it? What did it look like?
History of previous seizures (PMHx, FHx)Current illness? Trauma/abuse?
Length of postictal phase
![Page 20: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/20.jpg)
List of current medications
Include any antipyretics given (time and dose)
Do the parents have any anticonvulsant medications (rectal diazepam)?
Have the patients given any anticonvulsant medications (time and dose)?
Prehospital Assessment
![Page 21: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/21.jpg)
Prehospital Management
If actively seizing >5 mins and parent has not given rectal diazepam, administer it
Document time and dose
Continue O2, suction
Follow BLS guidelines (BVM if inadequate oxygenation)
Call EMS to transfer to ED
Obtain IV/IO access if possible and does not delay definitive care
![Page 22: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/22.jpg)
Objective #4
What do I do with febrile seizures?
![Page 23: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/23.jpg)
What’s a Febrile Seizure?
Caused by increase in core body temp > 100.4F (38C)
Threshold of temp which may trigger seizures is unique to each child
![Page 24: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/24.jpg)
Febrile Seizure Facts
Benign
Peak occurrence: between 6 months to 5 years of age
May be either simple or complex
Accompanied by fever (before, during, after) WITHOUT ANY:CNS infection
Metabolic disturbanceUnderlying structural brain abnormality
![Page 25: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/25.jpg)
2 Types of Febrile Seizures
Simple Complex
Seizure lasting < 15 mins
Generalized
Occurs ONCE in a 24 hour period
Seizure lasting > 15 mins
Focal
Occurs MORE THAN ONCE in a 24 hour period
![Page 26: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/26.jpg)
Prehospital Assessment
1) Assess ABCs +D x 2 (Dextrose, Disability)
2) Obtain seizure history:
How long was it? What did it look like?
History of previous seizures (PMHx, FHx)Current illness? Trauma/abuse?
Length of postictal phase
3) Get a list of current meds
![Page 27: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/27.jpg)
Prehospital Management
Monitor ABCDs
Position with C-Spine protection (if trauma)
Treat fever or underlying source of infection
Observe and transfer to ED if necessary
![Page 28: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/28.jpg)
Objective #5
This kid seized for the first time but looks great now. Do I really have to
call neurology?
![Page 29: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/29.jpg)
First Unprovoked Seizure
First seizure that occurs WITHOUT an immediate precipitating event
Etiology Remote symptomatic:
Related to a pre-existing brain abnormality/insult
Cryptogenic/idiopathic: no known cause
Can present as a:Partial seizure
Generalized, tonic-clonic seizureTonic seizure
![Page 30: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/30.jpg)
Prehospital Assessment
1) Assess ABCs +D x 2 (Dextrose, Disability)
2) Obtain seizure history:
How long was it? What did it look like?
History of previous seizures (PMHx, FHx)Current illness? Trauma/abuse?
Length of postictal phase
3) Get a list of current meds
![Page 31: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/31.jpg)
Prehospital Assessment
Monitor ABCDs
Position with C-Spine protection (if trauma)
Observe and transfer to ED if necessary
![Page 32: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/32.jpg)
Recurrence Risk After First Unprovoked Seizure
Majority of children will have few or no recurrences:approximately 10-20% will have additional seizures regardless of therapy
Predictors of recurrence include: Abnormal EEG
Underlying etiologyAbnormal neurologic exams
Remote symptomatic- recurrence risk over 2 years is > 50%Cryptogenic/idiopathic- recurrence risk over 2 years is 30-50%
Hirtz D et al. Neurology. 2003
![Page 33: Office Emergencies: Seizure Review](https://reader034.fdocuments.us/reader034/viewer/2022042814/555e4dcad8b42ad74a8b4aa8/html5/thumbnails/33.jpg)
Objective #1 Objective #2 Objective #3 Objective #4 Objective #5
Don’t Panic. ABCDs is your mantra.
Call for help.
If actively seizing or postictal place in recovery position.
If trauma suspected, place in C-collar and jaw thrust to ensure adequate airway
We quickly reviewed seizure classifications.
Remember, a lot of other conditions can mimic seizure activity. Verbal and physical stimulation won’t
interrupt a seizure.
Status epilepticus is a true medical emergency
ABCDs, oxygen, suction, recovery position Rectal diastat/IN versed
Call EMS
Simple febrile seizures need no further work up or evaluation besides treating underlying
cause for fever
Complex febrile seizures need further evaluation
First-time unprovoked seizures may or may not need immediate neurology consultation.
~10% of kids will have another seizure at some point
