Overview Ø Case based Ø Presentation of illness Ø Important questions to ask Ø Management Ø Physical findings Ø Work up Ø Summary
Pediatric Seizures Ø Most common neurologic disorder in childhood Ø 4 -6% of all kids will have 1 seizure before 16 y/o
Ø 5 year old female Case One Ø GTC seizure Ø Started 15 minutes ago Ø T-101, P-155, RR-40, BP-110/80, Ox Sat-89% Ø What would you like to do? Ø What history do you want to know?
Useful History for Seizure Ø Ø Ø Ø Does s/he have a fever? Does s/he have a seizure disorder? Ø If yes, is s/he on anti-seizure meds? Ø If yes, is s/he taking them, or any recent changes? Any trauma? Any medicines s/he had access to? How was s/he before the seizure started? Is s/he developmentally normal? Bottle or breast? Did you have a party last night?
Case One PMHx former 27 week’er Ø Has a known seizure disorder Ø On phenobarb Ø Has a fever and is seizing
Case One Getting started Ø Oxygen, NPA Ø Ask for IV access and d-stick Ø Ask to draw up Benzo (or phenobarb)
Seizure IV Medication Dosages Ø Lorazepam 0. 1 mg/kg Ø Dilantin Ø Phenobarbital 20 mg/kg Ø Valproic 20 mg/kg Acid
I ain’t got no… IV access. . . Ø Lorazepam Diazepam Ø Midazolam Ø Fosphenytoin Ø 0. 1 mg / kg IM 0. 5 mg / kg PR 0. 1 mg / kg IM 0. 5 mg / kg IM 0. 2 mg / kg Intranasal 0. 15 mg / kg PR 20 PE/ kg IM

Simple Febrile Seizures Ø Work-up Ø Find Ø If source of fever and treat it you think they have meningitis tap them ØLow threshold to tap kids less than 12 months
Complex Febrile Seizures Ø Work-up Ø Find source of fever and treat it Ø Work up for seizure
Febrile Seizures Antipyretics (what do you tell parents? ) Ø Worth giving, but no study shows you can prevent future febrile seizures

If Hyponatremic Ø If less than 125 m. Eq/l and seizing Ø 3%NS 3 cc/kg Ø Repeat with the goal to get up to 125 m. Eq/l which should stop seizures Hypothermia(<36. 5 or 97. 7), bottle fed, seizing check Na+
Case Four Ø 4 month old brought in by mom, seizing. She says she went to check on him and he was shaking all over. Tried to give him a bath because she thought he was cold but still shaking. Ø T-99. 1, P-170, RR-25, BP-110/80, Ox sat-89% Ø What physical findings would you look for?
Physical Findings to Look For Physical (obviously complete exam including) Ø “Is the baby seizing? ” Ø Signs of infection Ø Fever or hypothermia Signs of trauma Ø Organomegaly Ø Dysmorphic features Ø Big head, little head, VP shunt Ø Skin findings Ø
Neurofibomatosis Think about these…. If you see these…. . Order one of these…. .

Case Four
Case Four What do you want to do?
Case Four Airway (if not already intubated) Ø Fosphenytoin or phenobarb Ø Mannitol (is BP adequate? ) Ø Nearest pediatric neurosurgeon Ø Any other children at home? Ø Document the story well!! Ø
Case Five Ø 7 year old was at home working on his computer and parents heard a thump, they ran upstairs and found him seizing. Ø Lasted 2 minutes, he was tired for 30 minutes and now back to baseline Ø What would your work up be?
Case Five Ø If normal exam and no significant PMHx Ø Will need outpatient EEG, outpatient neurology Ø Possibly an MRI of brain Ø No Head CT Ø (some say 1/1000 mortality for each pediatric head CT) Ø No Blood work
Who gets a scan? Ø Ø Ø Ø Ø Focal seizure Persistent seizure Focal neurological deficit VPS Neurocutaneous disorder Signs of increased ICP History of trauma Immunocompromised Bleeding disorder (sickle cell, hyper or hypocoagulable)
Who gets labs? Bedside glucose: Ø Think about it often Electrolytes for: Ø Prolonged or persistent seizures Ø Younger than 6 months old Ø History of metabolic disorder, diabetes, dehydration, excess water intake, altered LOC
Who gets labs? Tox screen if altered LOC CSF for: Ø neonatal seizures Ø altered LOC, prolonged postictal period Ø signs of meningitis

If Hypoglycemic Ø Dextrose Ø D 5 NS Ø D 10 NS Ø D 25 NS (0. 25 -1 g/kg) 10 cc/kg 5 cc/kg 2 cc/kg 50 Remember to start an infusion
The Basics as always…. Ø Airway Ø Oxygen (non rebreather) Ø NP airway Ø Positioning Ø Breathing Ø remember Ø Circulation Ø Fluids Ø cricoid pressure if BVM if needed (NS) D, D, D, D duhhhhhh… Ø Dextrose …. . check d-stick
Access Ø Ø Ø Three attempts at IV Ø Consider other routes Think IM, PR, intranasal Ø IM Lorazepam Ø IM, PR, Intranasal Midazolam Ø PR Diazapam (Diastat) Agree on a weight and ask for meds early Ø Broslow? Other routine? Ø Not the best time to be practicing multiplication
Additional Pearls
Pyridoxine (Vit B 6) Ø Consider for persistent seizures in patient <1 yr Ø 50 -100 mg IV Ø Consider in suspected Isoniazid toxicity Ø Initial dose 70 mg/kg
Fosphenytoin Nicer to veins Ø Can be infused rapidly with less hypotension Ø 20 Phenytoin equivalents/kg load Ø

Case Seven Ø PE Ø No sign of trauma Ø No rashes Ø Well hydrated Ø No dysmorphic features Ø Normal tone Ø Eyes deviated to the left Ø Persistent lip smacking/sucking/chewing Ø What would you like to do?
