Status Epilepticus: Follow-up
Updated: Aug 24, 2009
Follow-up
Further Inpatient Care
- Emergency physicians must stop the seizures, stabilize the patient's medical condition, look for the etiology of the seizures, coordinate care with appropriate physicians, and make disposition to the appropriate service and medical unit.
- Care of the patient may involve interaction with a number of specialty or primary care physicians, including neurologists, neurosurgeons, internists, pediatricians, family practitioners, or intensivists.
- Continuous EEG monitoring may be desirable if a question exists about termination of status epilepticus or the presence of subtle status epilepticus.
- Coordinate treatment of associated injuries or complications with the inpatient service.
Further Outpatient Care
- Most patients with status epilepticus are admitted to the hospital not only for seizure control but also for treatment of other medical conditions that may be causing the seizures.
- Patients with a flurry of seizures that are easily controlled might conceivably be discharged after several hours of observation.
- The presence and capability of caretakers, proximity to the hospital, and comorbid medical conditions all factor into this decision.
Transfer
- Failure to terminate the seizures or need for critical care may be reasons for transfer. Transfer to a facility with expertise in this area may be desirable after the patient's condition has been stabilized.
Deterrence/Prevention
- Encourage anticonvulsant therapy compliance and alcohol abstinence.
- Emphasize the importance of regular medical attention for medication adjustment.
- Arrange for follow-up visits to adjust medications and for further medical workup and care.
Complications
- Complications of status epilepticus are many. As discussed in Pathophysiology section, current thought is that the abnormal electrical discharges themselves may cause neuronal damage.
- Systemic complications
- Hyperthermia
- Acidosis
- Hypotension
- Respiratory failure
- Rhabdomyolysis
- Aspiration
Prognosis
- Prognosis is related most strongly to the underlying process causing status epilepticus. For example, if meningitis is the etiology, the course of that disease dictates outcome.
- Patients with status epilepticus from anticonvulsant irregularity or those with alcohol-related seizures generally have a favorable prognosis if treatment is commenced rapidly and complications are prevented.
Patient Education
- Reinforcement of compliance with prescribed medications at routine clinical encounters may be helpful.

Miscellaneous
Medicolegal Pitfalls
- Failure to diagnose and treat the underlying cause of the seizures is a major pitfall because status epilepticus is often secondary to another pathologic process.
- Failure to recognize associated injuries or complications, such as aspiration pneumonia, is a potential problem.
- Failure to identify subtle or nonconvulsive status epilepticus in the patient with a coma or altered mental status but without convulsive motor seizures is an increasingly recognized pitfall.
- Seizures in association with hypertension in late pregnancy (or postpartum) may represent eclampsia.
Special Concerns
- In a small case series, several patients post-cardiac arrest treated with therapeutic hypothermia who developed postanoxic status epilepticus had a favorable outcome with aggressive treatment of the status epilepticus.7
- A paradox currently exists in that the criterion standard for diagnosing status epilepticus, the EEG, rarely is available in the acute-care setting.
- The work of Treiman et al suggests that electrical status epilepticus often persists when clinical seizure activity has ceased.8
- High clinical suspicion for continued unresponsiveness from this subtle status epilepticus is necessary along with timely consultations and occasional insistence on obtaining EEG.
