Definition
Status epilepticus is defined as continuous clinical and/or electroencephalographic seizure persisting longer than 5 minutes or the occurrence of two or more episodes of seizures within one hour without returning to the baseline level of consciousness between the seizures.[1]
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. Status epilepticus is a life threatening condition by itself because it results in serious immediate and long term morbidity and mortality if the convulsive seize is not terminated by 30 minutes; therefore, treatment is required urgently.
Common Causes
- Alcoholism
- Brain abscess
- Brain trauma
- Cardiac arrest
- Cerebrovascular disorders
- CNS tumor
- Drug toxicity
- Electrolytes abnormalities
- Encephalitis
- Hypertensive encephalopathy
- Hypoglycemia
- Hypoxia
- Low antiepileptic drug levels in patients with epilepsy
- Meningitis
- Sepsis
- Stroke
- Uremia
- Withdrawal from opioids, benzodiazepine, barbiturates or alcohol[2][1]
Management
Shown below is an algorithm summarizing the approach to status epilepticus. The goal of the treatment is to stop the seizure as soon as possible; therefore, begin the general measures and administer the antiepileptic medications (AED) SIMULTANEOUSLY.
Characterize the symptoms: ❑ Aura (altered vision and/or hearing), AND/OR ❑ Tonic phase with muscle spasms, AND/OR ❑ Rapid jerky movement, AND/OR ❑ Uprolling of eyes, AND/OR ❑ Tongue bite, AND/OR ❑ Incontinence | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
General measures to be done SIMULTANEOUSLY and in PARALLEL to the administration of antiepileptic medications (Emergency): Begin initial care: ❑ Turn patient to side ❑ Secure airway ❑ Assess respiratory and cardiac functions ❑ Administer high concentration O2 ❑ Establish IV access ❑ Institute regular monitoring for pulse, blood pressure, temperature ❑ ECG monitoring ❑ Check fingerstick glucose, and correct hypoglycemia if present (Emergency) Order labs: Consider vitamin deficiencies: Consider alternative diagnosis: Treat acidosis if severe | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Administer AED (Emergency): | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Recurrent or ongoing seizure 10 min after onset? (Emergency) ❑ Repeat the previous regimen only ONCE | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Recurrent or ongoing seizure 30 mins after onset? (Emergency) ❑ IV phenytoin (15-18 mg/kg at 50 mg/min): Slow IV infusion, IM is not recommended, monitor ECG during the infusion OR ❑ IV fosphenytoin (15-20 mg phenytoin equivalents (PE)/kg at 50-100 mg PE/min): monitor ECG during the infusion OR ❑ IV phenobarbital (10-15 mg/kg at 100 mg/min) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Ongoing seizure 60 mins after onset? (Emergency) Start anesthesia (reduce the doses after 2-3 days): Ensure full intensive care support ❑ ICU admission and continuous monitoring | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adapted from the 2012 National Institute for Health and Care Excellence (NICE) clinical guidelines.
