Status Epilepticus
PED-22
Diagnosis
Persistent seizures
Confirm ABCs: Airway, Breathing, Circulation
Increase O2 to 100%, consider intubation
Place monitors: ECG, SpO2, BP, EtCO2
Obtain IV access
Stop local anesthetic infusion/injection
Check glucose. If < 60 mg/dL, give D25W IV:
- < 2 years: 4 mL/kg
- ≥ 2 years: 2 mL/kg
Preop/PACU/Natural Airway
Prepare to immediately intubate, if needed
Give benzodiazepine, IF available
- IF IV access: Lorazepam 0.1-0.2 mg/kg (MAX 4mg) may give 2nd dose
- OR
- Midazolam or diazepam 0.1-0.2 mg/kg (MAX 10 mg) may give 2nd dose
- IF NO IV access: Midazolam intranasal or IM 0.4 mg/kg (MAX 20 mg)
If seizures continue, go to "Intraop/Assisted Ventilation"
Intraop/Assisted Ventilation
Maintain adequate ventilation
Increase inhaled anesthetic to 1.5-2 MAC, or give propofol 2 mg/kg IV (avoid if on ketogenic diet) or midazolam 0.1 mg/kg IV (repeat 2x every 3 min, if needed)
If movement could be dangerous, consider neuromuscular blockade and pausing surgery
Create safer environment, if needed (e.g. removal from Mayfield pins)
If seizure >6 minutes, consider anticonvulsants in consultation with ICU and neurology:
- levetiracetam 50 mg/kg (MAX 4.5 g) IV
- After 10 min, if needed, give fosphenytoin 20 mg/kg (MAX 1.5 g) IV or valproic acid 40 mg/kg (MAX 3 g) IV
Watch for myocardial suppression, vasoplegia, or rhabdomyolysis: may be associated with poorly controlled or prolonged seizures
If seizure ≥ 15 min, consult expert and see American Epilepsy Society Guidelines
Consider ABG/VBG and temperature monitoring
Consider PICU postop
Crisis Management (If Severe)
Notify surgeon, call for help and code cart
Call for Transesophageal Echocardiography
Start chest compressions
Give epinephrine 1-10 MICROgrams/kg IV/IO
If cardiac arrest, go to CARDIAC ARREST
Consider ECMO
