Published 14/03/2024

Paediatric Status Epilepticus

Set-up:

In ED RESUS

Lines/access:

2x 22G peripheral cannulas

Infusions:

Phenytoin infusion prepared by bedside (not connected)

Airway:

Own, NRB on

Ventilator:

Not required initially, Oxylog available by bedside

Other:

Paediatric airway trolley and equipment

CATS guidelines, intubation checklist and infusion calculator available on request (printed out)

Clinical Setting

I: You are the ICU registrar. The ED registrar bleeps you with a referral

S: There is a child in resus who has been admitted with tonic-clonic seizures

B: 6M with known epilepsy admitted following a tonic-clonic seizure at home (20 min ago). Further tonic-clonic seizure observed in resus by the registrar. He received diazepam with LAS and 1 dose IV lorazepam in ED

A: Drowsy, maintaining own airway but concerns given multiple seizures

R: 2 doses of benzodiazepine given so need additional support

Potential Clinical Course

  • Initially A own, B SpO2 100% on 15L O2, chest clear, C HR102 bpm, BP 98/54, D E1V2M5
  • Shortly after arrival patient has further seizure (3rd since admission)- appropriately starts phenytoin infusion/considers Keppra/status algorithm
  • Opens/supports airway/suctions
  • Gas provided when asked for:

pH 7.30, pO2 35.3, pCO2 4.5, Na 143, K 4.5, Lac 9, BE – 7.1

  • Asks for glucose (5.7)
  • Asks for temperature (37.9)
  • Gives fluid bolus +/- asks for antibiotics
  • Patient remains drowsy throughout scenario with no improvement in GCS. If prolonged deliberation can have further seizures

 

DECISION TO INTUBATE

  • Calculates WETFLAG for patient
    • (Estimated weight should be 20kg) – if using age +4 x2
    • (Accept weight 25kg) – if using (age x3) +7
  • Calculates appropriate ETT size and distance, appropriate MAC blade
  • Calculates appropriate drug doses & plan for intubation
  • Ensures appropriate equipment available (ventilator, pumps, infusions)
  • Liaises with paediatric team/CATS & contacts ODP
  • Explains what is about to happen to family and informs senior
  • Considers organising septic screen/CXR/CT head
  • CATS call at the end of scenario asking for an update: please hand over

 

End of scenario (Scenario can also be terminated after calculations and explanations prior to proceeding to drug assisted intubation)

Faculty Roles

ED nurse:

  • You are a senior ED nurse
  • The ED reg is busy with other patients and asked you to stay with this patient
  • This is a 6M with tonic clonic seizures (he has had 1 at home and 1 in resus) and has been given 2 doses of benzodiazepines (1 with LAS).
  • You are worried that this patient has continued to seize despite treatment
  • You sent initial blood tests to the lab when you cannulated (FBC, U&Es and CRP)
  • His parent is incredibly anxious, and you want the ICU doctor to reassure them
  • You take direction well, and can perform tasks asked if you in a timely fashion, you just lack impetus
  • If the candidate asks for the on-call ODP say that you’ve called, and they are on the way but that you can help them get any equipment needed

 

Parent:

  • You are worried about your son, his epilepsy is usually very well-controlled.
  • You want to know what is going on and when he can go home.
  • You are worried this is your fault because he’s not been himself these last few days and you just thought he had a cold.
  • You are not disruptive but refuse to leave your sons bedside and hold his hand throughout. When he has a seizure, you get very upset and distressed.
  • If you hear the doctor discussing intubation you get very worried. He has never been intubated/been to ICU before, and you don’t know what this means. You just want an explanation and if you get one you are amenable.
