Status Epilepticus in Children


Status epilepticus is considered to have occurred when a generalised tonic-clonic seizure has lasted greater than 30 minutes.



  • Resuscitation
    Terminate seizures
    Clinical and Historical assessment for cause


  • Call for help – anaesthesia, paediatric neurologist
  • Airway – open and secure airway, recovery position, high flow oxygen
  • Breathing – ensure ventilation
  • Circulation – ensure adequate circulation (20mL/kg crystalloid bolus), consider early antibiotic use to cover meningitis, routine bloods
  • Disability
    — check conscious state, interictal periods, localising signs, pupillary response, glucose level, check for full fontanelle and neck stiffness (meningitis)
    — terminate seizure:
    -> rectal diazepam – 0.5mg/kg
    -> buccal midazolam – 0.5mg/kg
    -> IV lorazepam 0.1mg/kg
    -> IV midazolam 0.15mg/kg
    -> PR paraldehyde 0.4mg/kg (mixed 1:1 in olive oil)
    -> phenytoin 18mg/kg over 30min
    -> phenobarbitone 20mg/kg IV over 20 min
    -> thiopentone 4mg/kg with RSI
    -> volatile anaesthesia
    -> surgery
  • Exposure – rash to suggest infectious cause (esp. meningococcaemia), fever, poisoning (ecstasy, cocaine, saliciylates)

Other Management

  • consider empiric therapy of intracranial hypertension (0.25-0.5g/kg mannitol)
  • look for complications: aspiration, arrhythmias, hypertension, APO, hyperthermia, DIC, rhabdomyolysis
  • maintain normoglycaemia
  • restrict fluids to 60% maintenance to avoid hyponatraemia
  • normalised sodium to 135-145
  • gastric decompression with NGT
  • normothermia
  • ventilate to CO2 – 35-40
  • dexamethasone 0.2mg/kg bd for cerebral oedema from SOL
  • IDC

Diagnostic possibilities (COMATOSE)

  • C – convulsion (primary or SOL)
  • O – overdose
  • M – meningitis
  • A – adrenal failure
  • T – trauma
  • O – organ failure
  • S – stroke
  • E – end stage hypoxic ischaemic encephalopathy
