Status Epilepticus

Snapshot
  • 23 year old man, history of two traumatic brain injuries and subsequent epilepsy which present as an unresponsive staring spell with automatism of his left hand opening and clenching lasting two to five minutes, brought in by family after they noticed an episode at dinner. Family concerned that even though his automatism has not been constant, he remains unreponsive
 Non-convulsive seizure on EEG.
Introduction
  • Definition
    • more than 5 minutes of generalized convulsive seizure 
    • two or more seizure episodes without recovery of consciousness in between
    • seizures maybe convulsive or non-convulsive
  • A medical emergency with high mortality
    • 13% in young adults
    • 30% in elderly
Evaluation
  • Possible etiologies
    • intracranial bleeding, ischemic infarction, arterio-venous malformations, venous sinus thrombosis, amyloid angiopathy
    • meningitis, meningoencephalitis, abcess
    • trauma
    • CNS vasculitis, lupus
    • gross electrolyte abnormalities
    • cocaine, PCP, amphetamines, ethanol
    • medications or lack of medications
    • tumor
  • Differential diagnosis
    • hypoglycemia
    • stroke, transient ischemic attack
    • myoclonus, distonia
    • narcolepsy, cataplexy
    • complicated migraine
    • panic attack
    • transient global amnesia
    • pseudoseizures, psychogenic
    • malingering
  • Immediate work up
    • ABCs, oxygen sat, coma exam, blood glucose
    • ABG, ECG, place on cardiac monitor
    • CBC, Chem 10, LFT, Troponin, AED levels, tox screen
Treatment
  • Pharmacologic
    • have IV lorazepam in syringe handy
      • Avoid impulse to give benzos at onset!
    • maintain patient in lateral decubitus position
    • clear area of potentially injurous objects, place down protective padding
    • administer O2 via nasal cannula, place two IVs, finger stick glucose
    • if episode <5 minutes, wait 1-2 minutes
      • majority of seizures resolve spontaneously
      • draw labs and do immediate work up (see above)
      • thiamine IV, 50% dextrose IV
    • watch for respiratory suppression
      • onset of lorazepam ~ 3minutes
    • if seizure still persistent in
      • 10-20 minutes - IV fosphenytoin, phenytoin, or valproate
      • 21-60 minutes - IV midazolam, propofol, phenobarbital, or more valproate
        • all of the above except valproate require intubation
      • >60 minutes - IV phenobarbital
Prognosis and Complications
  • Prognosis
    • 15.6% mortality in those with first episode
    • 4.8% in those with repeated episodes
    • length of episodes predisposes patient to complications
  • Complications
    • lactic acidosis
    • hypoxia
    • hyperthermia
    • rhabdomyolysis
    • cerebral edema
    • hypotension
